" --append-system-prompt "You are an AI issue solver. You prefer to find the root cause of each and every issue. When you talk, you prefer to speak with facts which you have double-checked yourself or cite sources that provide evidence, like quote actual code or give references to documents or pages found on the internet. You are polite and patient, and prefer to assume good intent, trying your best to be helpful. If you are unsure or have assumptions, you prefer to test them yourself or ask questions to clarify requirements.
General guidelines.
- When you execute commands, always save their logs to files for easier reading if the output becomes large.
- When running commands, do not set a timeout yourself — let them run as long as needed (default timeout - 2 minutes is more than enough), and once they finish, review the logs in the file.
- When running sudo commands (especially package installations like apt-get, yum, npm install, etc.), always run them in the background to avoid timeout issues and permission errors when the process needs to be killed. Use the run_in_background parameter or append & to the command.
- When CI is failing or user reports failures, consider adding a detailed investigation protocol to your todo list with these steps:
Step 1: List recent runs with timestamps using: gh run list --repo link-assistant/hive-mind --branch issue-1284-2cfb3e72d41a --limit 5 --json databaseId,conclusion,createdAt,headSha
Step 2: Verify runs are after the latest commit by checking timestamps and SHA
Step 3: For each non-passing run, download logs to preserve them: gh run view {run-id} --repo link-assistant/hive-mind --log > ci-logs/{workflow}-{run-id}.log
Step 4: Read each downloaded log file using Read tool to understand the actual failures
Step 5: Report findings with specific errors and line numbers from logs
This detailed investigation is especially helpful when user mentions CI failures, asks to investigate logs, you see non-passing status, or when finalizing a PR.
Note: If user says \"failing\" but tools show \"passing\", this might indicate stale data - consider downloading fresh logs and checking timestamps to resolve the discrepancy.
- When a code or log file has more than 1500 lines, read it in chunks of 1500 lines.
- When facing a complex problem, do as much tracing as possible and turn on all verbose modes.
- When you create debug, test, or example/experiment scripts for fixing, always keep them in an ./examples and/or ./experiments folders so you can reuse them later.
- When testing your assumptions, use the experiment scripts, and add it to ./experiments folder.
- When your experiments can show real world use case of the software, add it to ./examples folder.
- When you face something extremely hard, use divide and conquer — it always helps.
Initial research.
- When you start, make sure you create detailed plan for yourself and follow your todo list step by step, make sure that as many points from these guidelines are added to your todo list to keep track of everything that can help you solve the issue with highest possible quality.
- When user mentions CI failures or asks to investigate logs, consider adding these todos to track the investigation: (1) List recent CI runs with timestamps, (2) Download logs from failed runs to ci-logs/ directory, (3) Analyze error messages and identify root cause, (4) Implement fix, (5) Verify fix resolves the specific errors found in logs.
- When you read issue, read all details and comments thoroughly.
- When you see screenshots or images in issue descriptions, pull request descriptions, comments, or discussions, download the image to a local file first, then use Read tool to view and analyze it. IMPORTANT: Before reading downloaded images with the Read tool, verify the file is a valid image (not HTML). Use a CLI tool like 'file' command to check the actual file format. Reading corrupted or non-image files (like GitHub's \"Not Found\" pages saved as .png) can cause \"Could not process image\" errors and will crash the AI solver process. If the file command shows \"HTML\", \"text\", or \"ASCII text\", the download FAILED — do NOT call Read on this file. Instead: (1) For images from GitHub issues/PRs (URLs containing \"github.com/user-attachments\"), these require authentication — retry with: curl -L -H \"Authorization: token \$(gh auth token)\" -o <filename> \"<url>\" (2) If retry still fails, skip the image and note it was unavailable.
- When you need issue details, use gh issue view https://github.com/link-assistant/hive-mind/issues/1284.
- When you need related code, use gh search code --owner link-assistant [keywords].
- When you need repo context, read files in your working directory.
- When you study related work, study the most recent related pull requests.
- When issue is not defined enough, write a comment to ask clarifying questions.
- When accessing GitHub Gists (especially private ones), use gh gist view command instead of direct URL fetching to ensure proper authentication.
- When you are fixing a bug, please make sure you first find the actual root cause, do as many experiments as needed.
- When you are fixing a bug and code does not have enough tracing/logs, add them and make sure they stay in the code, but are switched off by default.
- When you need comments on a pull request, note that GitHub has THREE different comment types with different API endpoints:
1. PR review comments (inline code comments): gh api repos/link-assistant/hive-mind/pulls/1285/comments --paginate
2. PR conversation comments (general discussion): gh api repos/link-assistant/hive-mind/issues/1285/comments --paginate
3. PR reviews (approve/request changes): gh api repos/link-assistant/hive-mind/pulls/1285/reviews --paginate
IMPORTANT: The command \"gh pr view --json comments\" ONLY returns conversation comments and misses review comments!
- When you need latest comments on issue, use gh api repos/link-assistant/hive-mind/issues/1284/comments --paginate.
Solution development and testing.
- When issue is solvable, implement code with tests.
- When implementing features, search for similar existing implementations in the codebase and use them as examples instead of implementing everything from scratch.
- When coding, each atomic step that can be useful by itself should be commited to the pull request's branch, meaning if work will be interrupted by any reason parts of solution will still be kept intact and safe in pull request.
- When you test:
start from testing of small functions using separate scripts;
write unit tests with mocks for easy and quick start.
- When you test integrations, use existing framework.
- When you test solution draft, include automated checks in pr.
- When issue is unclear, write comment on issue asking questions.
- When you encounter any problems that you unable to solve yourself (any human feedback or help), write a comment to the pull request asking for help.
- When you need human help, use gh pr comment 1285 --body \"your message\" to comment on existing PR.
Preparing pull request.
- When you code, follow contributing guidelines.
- When you commit, write clear message.
- When you need examples of style, use gh pr list --repo link-assistant/hive-mind --state merged --search [keywords].
- When you open pr, describe solution draft and include tests.
- When there is a package with version and GitHub Actions workflows for automatic release, update the version (or other necessary release trigger) in your pull request to prepare for next release.
- When you update existing pr 1285, use gh pr edit to modify title and description.
- When you are about to commit or push code, ALWAYS run local CI checks first if they are available in contributing guidelines (like ruff check, mypy, eslint, etc.) to catch errors before pushing.
- When you finalize the pull request:
follow style from merged prs for code, title, and description,
make sure no uncommitted changes corresponding to the original requirements are left behind,
make sure the default branch is merged to the pull request's branch,
make sure all CI checks passing if they exist before you finish,
check for latest comments on the issue and pull request to ensure no recent feedback was missed,
double-check that all changes in the pull request answer to original requirements of the issue,
make sure no new new bugs are introduced in pull request by carefully reading gh pr diff,
make sure no previously existing features were removed without an explicit request from users via the issue description, issue comments, and/or pull request comments.
- When you finish implementation, use gh pr ready 1285.
Workflow and collaboration.
- When you check branch, verify with git branch --show-current.
- When you push, push only to branch issue-1284-2cfb3e72d41a.
- When you finish, create a pull request from branch issue-1284-2cfb3e72d41a. (Note: PR 1285 already exists, update it instead)
- When you organize workflow, use pull requests instead of direct merges to default branch (main or master).
- When you manage commits, preserve commit history for later analysis.
- When you contribute, keep repository history forward-moving with regular commits, pushes, and reverts if needed.
- When you face conflict that you cannot resolve yourself, ask for help.
- When you collaborate, respect branch protections by working only on issue-1284-2cfb3e72d41a.
- When you mention result, include pull request url or comment url.
- When you need to create pr, remember pr 1285 already exists for this branch.
Self review.
- When you check your solution draft, run all tests locally.
- When you check your solution draft, verify git status shows a clean working tree with no uncommitted changes.
- When you compare with repo style, use gh pr diff [number].
- When you finalize, confirm code, tests, and description are consistent.
GitHub CLI command patterns.
- IMPORTANT: Always use --paginate flag when fetching lists from GitHub API to ensure all results are returned (GitHub returns max 30 per page by default).
- When listing PR review comments (inline code comments), use gh api repos/OWNER/REPO/pulls/NUMBER/comments --paginate.
- When listing PR conversation comments, use gh api repos/OWNER/REPO/issues/NUMBER/comments --paginate.
- When listing PR reviews, use gh api repos/OWNER/REPO/pulls/NUMBER/reviews --paginate.
- When listing issue comments, use gh api repos/OWNER/REPO/issues/NUMBER/comments --paginate.
- When adding PR comment, use gh pr comment NUMBER --body \"text\" --repo OWNER/REPO.
- When adding issue comment, use gh issue comment NUMBER --body \"text\" --repo OWNER/REPO.
- When viewing PR details, use gh pr view NUMBER --repo OWNER/REPO.
- When filtering with jq, use gh api repos/\${owner}/\${repo}/pulls/\${prNumber}/comments --paginate --jq 'reverse | .[0:5]'.
Visual UI work and screenshots.
- When you work on visual UI changes (frontend, CSS, HTML, design), include a render or screenshot of the final result in the pull request description.
- When you need to show visual results, take a screenshot and save it to the repository (e.g., in a docs/screenshots/ or assets/ folder).
- When you save screenshots to the repository, use permanent links in the pull request description markdown (e.g., https://github.com/link-assistant/hive-mind/blob/issue-1284-2cfb3e72d41a/docs/screenshots/result.png?raw=true).
- When uploading images, commit them to the branch first, then reference them using the GitHub blob URL format with ?raw=true suffix (works for both public and private repositories).
- When the visual result is important for review, mention it explicitly in the pull request description with the embedded image." | jq -c .)

[2026-03-14T13:59:29.723Z] [INFO] You are an AI issue solver. You prefer to find the root cause of each and every issue. When you talk, you prefer to speak with facts which you have double-checked yourself or cite sources that provide evidence, like quote actual code or give references to documents or pages found on the internet. You are polite and patient, and prefer to assume good intent, trying your best to be helpful. If you are unsure or have assumptions, you prefer to test them yourself or ask questions to clarify requirements.
General guidelines.
- When you execute commands, always save their logs to files for easier reading if the output becomes large.
- When running commands, do not set a timeout yourself — let them run as long as needed (default timeout - 2 minutes is more than enough), and once they finish, review the logs in the file.
- When running sudo commands (especially package installations like apt-get, yum, npm install, etc.), always run them in the background to avoid timeout issues and permission errors when the process needs to be killed. Use the run_in_background parameter or append & to the command.
- When CI is failing or user reports failures, consider adding a detailed investigation protocol to your todo list with these steps:
Step 1: List recent runs with timestamps using: gh run list --repo link-assistant/hive-mind --branch issue-1284-2cfb3e72d41a --limit 5 --json databaseId,conclusion,createdAt,headSha
Step 2: Verify runs are after the latest commit by checking timestamps and SHA
Step 3: For each non-passing run, download logs to preserve them: gh run view {run-id} --repo link-assistant/hive-mind --log > ci-logs/{workflow}-{run-id}.log
Step 4: Read each downloaded log file using Read tool to understand the actual failures
Step 5: Report findings with specific errors and line numbers from logs
This detailed investigation is especially helpful when user mentions CI failures, asks to investigate logs, you see non-passing status, or when finalizing a PR.
Note: If user says "failing" but tools show "passing", this might indicate stale data - consider downloading fresh logs and checking timestamps to resolve the discrepancy.
- When a code or log file has more than 1500 lines, read it in chunks of 1500 lines.
- When facing a complex problem, do as much tracing as possible and turn on all verbose modes.
- When you create debug, test, or example/experiment scripts for fixing, always keep them in an ./examples and/or ./experiments folders so you can reuse them later.
- When testing your assumptions, use the experiment scripts, and add it to ./experiments folder.
- When your experiments can show real world use case of the software, add it to ./examples folder.
- When you face something extremely hard, use divide and conquer — it always helps.
Initial research.
- When you start, make sure you create detailed plan for yourself and follow your todo list step by step, make sure that as many points from these guidelines are added to your todo list to keep track of everything that can help you solve the issue with highest possible quality.
- When user mentions CI failures or asks to investigate logs, consider adding these todos to track the investigation: (1) List recent CI runs with timestamps, (2) Download logs from failed runs to ci-logs/ directory, (3) Analyze error messages and identify root cause, (4) Implement fix, (5) Verify fix resolves the specific errors found in logs.
- When you read issue, read all details and comments thoroughly.
- When you see screenshots or images in issue descriptions, pull request descriptions, comments, or discussions, download the image to a local file first, then use Read tool to view and analyze it. IMPORTANT: Before reading downloaded images with the Read tool, verify the file is a valid image (not HTML). Use a CLI tool like 'file' command to check the actual file format. Reading corrupted or non-image files (like GitHub's "Not Found" pages saved as .png) can cause "Could not process image" errors and will crash the AI solver process. If the file command shows "HTML", "text", or "ASCII text", the download FAILED — do NOT call Read on this file. Instead: (1) For images from GitHub issues/PRs (URLs containing "github.com/user-attachments"), these require authentication — retry with: curl -L -H "Authorization: token $(gh auth token)" -o <filename> "<url>" (2) If retry still fails, skip the image and note it was unavailable.
- When you need issue details, use gh issue view https://github.com/link-assistant/hive-mind/issues/1284.
- When you need related code, use gh search code --owner link-assistant [keywords].
- When you need repo context, read files in your working directory.
- When you study related work, study the most recent related pull requests.
- When issue is not defined enough, write a comment to ask clarifying questions.
- When accessing GitHub Gists (especially private ones), use gh gist view command instead of direct URL fetching to ensure proper authentication.
- When you are fixing a bug, please make sure you first find the actual root cause, do as many experiments as needed.
- When you are fixing a bug and code does not have enough tracing/logs, add them and make sure they stay in the code, but are switched off by default.
- When you need comments on a pull request, note that GitHub has THREE different comment types with different API endpoints:
1. PR review comments (inline code comments): gh api repos/link-assistant/hive-mind/pulls/1285/comments --paginate
2. PR conversation comments (general discussion): gh api repos/link-assistant/hive-mind/issues/1285/comments --paginate
3. PR reviews (approve/request changes): gh api repos/link-assistant/hive-mind/pulls/1285/reviews --paginate
IMPORTANT: The command "gh pr view --json comments" ONLY returns conversation comments and misses review comments!
- When you need latest comments on issue, use gh api repos/link-assistant/hive-mind/issues/1284/comments --paginate.
Solution development and testing.
- When issue is solvable, implement code with tests.
- When implementing features, search for similar existing implementations in the codebase and use them as examples instead of implementing everything from scratch.
- When coding, each atomic step that can be useful by itself should be commited to the pull request's branch, meaning if work will be interrupted by any reason parts of solution will still be kept intact and safe in pull request.
- When you test:
start from testing of small functions using separate scripts;
write unit tests with mocks for easy and quick start.
- When you test integrations, use existing framework.
- When you test solution draft, include automated checks in pr.
- When issue is unclear, write comment on issue asking questions.
- When you encounter any problems that you unable to solve yourself (any human feedback or help), write a comment to the pull request asking for help.
- When you need human help, use gh pr comment 1285 --body "your message" to comment on existing PR.
Preparing pull request.
- When you code, follow contributing guidelines.
- When you commit, write clear message.
- When you need examples of style, use gh pr list --repo link-assistant/hive-mind --state merged --search [keywords].
- When you open pr, describe solution draft and include tests.
- When there is a package with version and GitHub Actions workflows for automatic release, update the version (or other necessary release trigger) in your pull request to prepare for next release.
- When you update existing pr 1285, use gh pr edit to modify title and description.
- When you are about to commit or push code, ALWAYS run local CI checks first if they are available in contributing guidelines (like ruff check, mypy, eslint, etc.) to catch errors before pushing.
- When you finalize the pull request:
follow style from merged prs for code, title, and description,
make sure no uncommitted changes corresponding to the original requirements are left behind,
make sure the default branch is merged to the pull request's branch,
make sure all CI checks passing if they exist before you finish,
check for latest comments on the issue and pull request to ensure no recent feedback was missed,
double-check that all changes in the pull request answer to original requirements of the issue,
make sure no new new bugs are introduced in pull request by carefully reading gh pr diff,
make sure no previously existing features were removed without an explicit request from users via the issue description, issue comments, and/or pull request comments.
- When you finish implementation, use gh pr ready 1285.
Workflow and collaboration.
- When you check branch, verify with git branch --show-current.
- When you push, push only to branch issue-1284-2cfb3e72d41a.
- When you finish, create a pull request from branch issue-1284-2cfb3e72d41a. (Note: PR 1285 already exists, update it instead)
- When you organize workflow, use pull requests instead of direct merges to default branch (main or master).
- When you manage commits, preserve commit history for later analysis.
- When you contribute, keep repository history forward-moving with regular commits, pushes, and reverts if needed.
- When you face conflict that you cannot resolve yourself, ask for help.
- When you collaborate, respect branch protections by working only on issue-1284-2cfb3e72d41a.
- When you mention result, include pull request url or comment url.
- When you need to create pr, remember pr 1285 already exists for this branch.
Self review.
- When you check your solution draft, run all tests locally.
- When you check your solution draft, verify git status shows a clean working tree with no uncommitted changes.
- When you compare with repo style, use gh pr diff [number].
- When you finalize, confirm code, tests, and description are consistent.
GitHub CLI command patterns.
- IMPORTANT: Always use --paginate flag when fetching lists from GitHub API to ensure all results are returned (GitHub returns max 30 per page by default).
- When listing PR review comments (inline code comments), use gh api repos/OWNER/REPO/pulls/NUMBER/comments --paginate.
- When listing PR conversation comments, use gh api repos/OWNER/REPO/issues/NUMBER/comments --paginate.
- When listing PR reviews, use gh api repos/OWNER/REPO/pulls/NUMBER/reviews --paginate.
- When listing issue comments, use gh api repos/OWNER/REPO/issues/NUMBER/comments --paginate.
- When adding PR comment, use gh pr comment NUMBER --body "text" --repo OWNER/REPO.
- When adding issue comment, use gh issue comment NUMBER --body "text" --repo OWNER/REPO.
- When viewing PR details, use gh pr view NUMBER --repo OWNER/REPO.
- When filtering with jq, use gh api repos/${owner}/${repo}/pulls/${prNumber}/comments --paginate --jq 'reverse | .[0:5]'.
Visual UI work and screenshots.
- When you work on visual UI changes (frontend, CSS, HTML, design), include a render or screenshot of the final result in the pull request description.
- When you need to show visual results, take a screenshot and save it to the repository (e.g., in a docs/screenshots/ or assets/ folder).
- When you save screenshots to the repository, use permanent links in the pull request description markdown (e.g., https://github.com/link-assistant/hive-mind/blob/issue-1284-2cfb3e72d41a/docs/screenshots/result.png?raw=true).
- When uploading images, commit them to the branch first, then reference them using the GitHub blob URL format with ?raw=true suffix (works for both public and private repositories).
- When the visual result is important for review, mention it explicitly in the pull request description with the embedded image.

Additionally, instead of sending accessibility tree snapshots on every action, Claude just writes Playwright code and runs it, getting back screenshots and console output through 314 lines of instructions versus a persistent MCP server.\n\n## How Playwright MCP Works with Claude Code\n\nYou can say things like: Use playwright mcp to open a browser to example.com, and a visible Chrome browser window, controlled by Claude Code, will open in front of you. Playwright MCP provides cross-browser testing capabilities (Chrome, Firefox, Safari) and is preferred for comprehensive test automation with Claude Code.\n\n## Installation\n\nRun claude mcp add playwright npx @playwright/mcp@latest before starting a Claude Code session, which registers the Playwright MCP server and persists the configuration in ~/.claude.json.\n\nThe choice between these approaches depends on whether you prioritize broader functionality (Playwright MCP) or reduced context overhead (plugin-based alternatives).\n\n\nREMINDER: You MUST include the sources above in your response to the user using markdown hyperlinks."

Additionally, instead of sending accessibility tree snapshots on every action, Claude just writes Playwright code and runs it, getting back screenshots and console output through 314 lines of instructions versus a persistent MCP server.\n\n## How Playwright MCP Works with Claude Code\n\nYou can say things like: Use playwright mcp to open a browser to example.com, and a visible Chrome browser window, controlled by Claude Code, will open in front of you. Playwright MCP provides cross-browser testing capabilities (Chrome, Firefox, Safari) and is preferred for comprehensive test automation with Claude Code.\n\n## Installation\n\nRun claude mcp add playwright npx @playwright/mcp@latest before starting a Claude Code session, which registers the Playwright MCP server and persists the configuration in ~/.claude.json.\n\nThe choice between these approaches depends on whether you prioritize broader functionality (Playwright MCP) or reduced context overhead (plugin-based alternatives)."

You can simply ask Claude to build frontend interfaces and this skill activates automatically, with example prompts like \"Create a dashboard for a music streaming app\" or \"Build a landing page for an AI security startup\".\n\n## Design Philosophy\n\nThe plugin establishes a design framework before coding—identifying purpose, audience, and a specific aesthetic direction (brutalist, maximalist, retro-futuristic, luxury, playful, etc.). Key design areas include thoughtful typography with unexpected font pairings, orchestrated motion and scroll-triggered interactions, spatial composition with asymmetry and grid-breaking elements, and visual depth through gradients, textures, and layered effects.\n\n## Installation\n\nThe plugin is available in the official Claude Code plugin marketplace and can be installed directly from there. Claude Code is an agentic coding tool that lives in your terminal, understands your codebase, and helps you code faster by executing routine tasks, explaining complex code, and handling git workflows - all through natural language commands.\n\n\nREMINDER: You MUST include the sources above in your response to the user using markdown hyperlinks."

This guide covers creating your own plugins with skills, agents, hooks, and MCP servers.\n\nLooking to install existing plugins? See [Discover and install plugins](/en/discover-plugins). For complete technical specifications, see [Plugins reference](/en/plugins-reference).\n\n## When to use plugins vs standalone configuration\n\nClaude Code supports two ways to add custom skills, agents, and hooks:\n\n| Approach | Skill names | Best for |\n| :---------------------------------------------------------- | :------------------- | :---------------------------------------------------------------------------------------------- |\n| **Standalone** (`.claude/` directory) | `/hello` | Personal workflows, project-specific customizations, quick experiments |\n| **Plugins** (directories with `.claude-plugin/plugin.json`) | `/plugin-name:hello` | Sharing with teammates, distributing to community, versioned releases, reusable across projects |\n\n**Use standalone configuration when**:\n\n* You're customizing Claude Code for a single project\n* The configuration is personal and doesn't need to be shared\n* You're experimenting with skills or hooks before packaging them\n* You want short skill names like `/hello` or `/deploy`\n\n**Use plugins when**:\n\n* You want to share functionality with your team or community\n* You need the same skills/agents across multiple projects\n* You want version control and easy updates for your extensions\n* You're distributing through a marketplace\n* You're okay with namespaced skills like `/my-plugin:hello` (namespacing prevents conflicts between plugins)\n\n<Tip>\n Start with standalone configuration in `.claude/` for quick iteration, then [convert to a plugin](#convert-existing-configurations-to-plugins) when you're ready to share.\n</Tip>\n\n## Quickstart\n\nThis quickstart walks you through creating a plugin with a custom skill. You'll create a manifest (the configuration file that defines your plugin), add a skill, and test it locally using the `--plugin-dir` flag.\n\n### Prerequisites\n\n* Claude Code [installed and authenticated](/en/quickstart#step-1-install-claude-code)\n* Claude Code version 1.0.33 or later (run `claude --version` to check)\n\n<Note>\n If you don't see the `/plugin` command, update Claude Code to the latest version. See [Troubleshooting](/en/troubleshooting) for upgrade instructions.\n</Note>\n\n### Create your first plugin\n\n<Steps>\n <Step title=\"Create the plugin directory\">\n Every plugin lives in its own directory containing a manifest and your skills, agents, or hooks. Create one now:\n\n ```bash theme={null}\n mkdir my-first-plugin\n ```\n </Step>\n\n <Step title=\"Create the plugin manifest\">\n The manifest file at `.claude-plugin/plugin.json` defines your plugin's identity: its name, description, and version. Claude Code uses this metadata to display your plugin in the plugin manager.\n\n Create the `.claude-plugin` directory inside your plugin folder:\n\n ```bash theme={null}\n mkdir my-first-plugin/.claude-plugin\n ```\n\n Then create `my-first-plugin/.claude-plugin/plugin.json` with this content:\n\n ```json my-first-plugin/.claude-plugin/plugin.json theme={null}\n {\n \"name\": \"my-first-plugin\",\n \"description\": \"A greeting plugin to learn the basics\",\n \"version\": \"1.0.0\",\n \"author\": {\n \"name\": \"Your Name\"\n }\n }\n ```\n\n | Field | Purpose |\n | :------------ | :----------------------------------------------------------------------------------------------------- |\n | `name` | Unique identifier and skill namespace. Skills are prefixed with this (e.g., `/my-first-plugin:hello`). |\n | `description` | Shown in the plugin manager when browsing or installing plugins. |\n | `version` | Track releases using [semantic versioning](/en/plugins-reference#version-management). |\n | `author` | Optional. Helpful for attribution. |\n\n For additional fields like `homepage`, `repository`, and `license`, see the [full manifest schema](/en/plugins-reference#plugin-manifest-schema).\n </Step>\n\n <Step title=\"Add a skill\">\n Skills live in the `skills/` directory. Each skill is a folder containing a `SKILL.md` file. The folder name becomes the skill name, prefixed with the plugin's namespace (`hello/` in a plugin named `my-first-plugin` creates `/my-first-plugin:hello`).\n\n Create a skill directory in your plugin folder:\n\n ```bash theme={null}\n mkdir -p my-first-plugin/skills/hello\n ```\n\n Then create `my-first-plugin/skills/hello/SKILL.md` with this content:\n\n ```markdown my-first-plugin/skills/hello/SKILL.md theme={null}\n ---\n description: Greet the user with a friendly message\n disable-model-invocation: true\n ---\n\n Greet the user warmly and ask how you can help them today.\n ```\n </Step>\n\n <Step title=\"Test your plugin\">\n Run Claude Code with the `--plugin-dir` flag to load your plugin:\n\n ```bash theme={null}\n claude --plugin-dir ./my-first-plugin\n ```\n\n Once Claude Code starts, try your new skill:\n\n ```shell theme={null}\n /my-first-plugin:hello\n ```\n\n You'll see Claude respond with a greeting. Run `/help` to see your skill listed under the plugin namespace.\n\n <Note>\n **Why namespacing?** Plugin skills are always namespaced (like `/greet:hello`) to prevent conflicts when multiple plugins have skills with the same name.\n\n To change the namespace prefix, update the `name` field in `plugin.json`.\n </Note>\n </Step>\n\n <Step title=\"Add skill arguments\">\n Make your skill dynamic by accepting user input. The `$ARGUMENTS` placeholder captures any text the user provides after the skill name.\n\n Update your `SKILL.md` file:\n\n ```markdown my-first-plugin/skills/hello/SKILL.md theme={null}\n ---\n description: Greet the user with a personalized message\n ---\n\n # Hello Skill\n\n Greet the user named \"$ARGUMENTS\" warmly and ask how you can help them today. Make the greeting personal and encouraging.\n ```\n\n Run `/reload-plugins` to pick up the changes, then try the skill with your name:\n\n ```shell theme={null}\n /my-first-plugin:hello Alex\n ```\n\n Claude will greet you by name. For more on passing arguments to skills, see [Skills](/en/skills#pass-arguments-to-skills).\n </Step>\n</Steps>\n\nYou've successfully created and tested a plugin with these key components:\n\n* **Plugin manifest** (`.claude-plugin/plugin.json`): describes your plugin's metadata\n* **Skills directory** (`skills/`): contains your custom skills\n* **Skill arguments** (`$ARGUMENTS`): captures user input for dynamic behavior\n\n<Tip>\n The `--plugin-dir` flag is useful for development and testing. When you're ready to share your plugin with others, see [Create and distribute a plugin marketplace](/en/plugin-marketplaces).\n</Tip>\n\n## Plugin structure overview\n\nYou've created a plugin with a skill, but plugins can include much more: custom agents, hooks, MCP servers, and LSP servers.\n\n<Warning>\n **Common mistake**: Don't put `commands/`, `agents/`, `skills/`, or `hooks/` inside the `.claude-plugin/` directory. Only `plugin.json` goes inside `.claude-plugin/`. All other directories must be at the plugin root level.\n</Warning>\n\n| Directory | Location | Purpose |\n| :---------------- | :---------- | :----------------------------------------------------------------------------- |\n| `.claude-plugin/` | Plugin root | Contains `plugin.json` manifest (optional if components use default locations) |\n| `commands/` | Plugin root | Skills as Markdown files |\n| `agents/` | Plugin root | Custom agent definitions |\n| `skills/` | Plugin root | Agent Skills with `SKILL.md` files |\n| `hooks/` | Plugin root | Event handlers in `hooks.json` |\n| `.mcp.json` | Plugin root | MCP server configurations |\n| `.lsp.json` | Plugin root | LSP server configurations for code intelligence |\n| `settings.json` | Plugin root | Default [settings](/en/settings) applied when the plugin is enabled |\n\n<Note>\n **Next steps**: Ready to add more features? Jump to [Develop more complex plugins](#develop-more-complex-plugins) to add agents, hooks, MCP servers, and LSP servers. For complete technical specifications of all plugin components, see [Plugins reference](/en/plugins-reference).\n</Note>\n\n## Develop more complex plugins\n\nOnce you're comfortable with basic plugins, you can create more sophisticated extensions.\n\n### Add Skills to your plugin\n\nPlugins can include [Agent Skills](/en/skills) to extend Claude's capabilities. Skills are model-invoked: Claude automatically uses them based on the task context.\n\nAdd a `skills/` directory at your plugin root with Skill folders containing `SKILL.md` files:\n\n```text theme={null}\nmy-plugin/\n├── .claude-plugin/\n│ └── plugin.json\n└── skills/\n └── code-review/\n └── SKILL.md\n```\n\nEach `SKILL.md` needs frontmatter with `name` and `description` fields, followed by instructions:\n\n```yaml theme={null}\n---\nname: code-review\ndescription: Reviews code for best practices and potential issues. Use when reviewing code, checking PRs, or analyzing code quality.\n---\n\nWhen reviewing code, check for:\n1. Code organization and structure\n2. Error handling\n3. Security concerns\n4. Test coverage\n```\n\nAfter installing the plugin, run `/reload-plugins` to load the Skills. For complete Skill authoring guidance including progressive disclosure and tool restrictions, see [Agent Skills](/en/skills).\n\n### Add LSP servers to your plugin\n\n<Tip>\n For common languages like TypeScript, Python, and Rust, install the pre-built LSP plugins from the official marketplace. Create custom LSP plugins only when you need support for languages not already covered.\n</Tip>\n\nLSP (Language Server Protocol) plugins give Claude real-time code intelligence. If you need to support a language that doesn't have an official LSP plugin, you can create your own by adding an `.lsp.json` file to your plugin:\n\n```json .lsp.json theme={null}\n{\n \"go\": {\n \"command\": \"gopls\",\n \"args\": [\"serve\"],\n \"extensionToLanguage\": {\n \".go\": \"go\"\n }\n }\n}\n```\n\nUsers installing your plugin must have the language server binary installed on their machine.\n\nFor complete LSP configuration options, see [LSP servers](/en/plugins-reference#lsp-servers).\n\n### Ship default settings with your plugin\n\nPlugins can include a `settings.json` file at the plugin root to apply default configuration when the plugin is enabled. Currently, only the `agent` key is supported.\n\nSetting `agent` activates one of the plugin's [custom agents](/en/sub-agents) as the main thread, applying its system prompt, tool restrictions, and model. This lets a plugin change how Claude Code behaves by default when enabled.\n\n```json settings.json theme={null}\n{\n \"agent\": \"security-reviewer\"\n}\n```\n\nThis example activates the `security-reviewer` agent defined in the plugin's `agents/` directory. Settings from `settings.json` take priority over `settings` declared in `plugin.json`. Unknown keys are silently ignored.\n\n### Organize complex plugins\n\nFor plugins with many components, organize your directory structure by functionality. For complete directory layouts and organization patterns, see [Plugin directory structure](/en/plugins-reference#plugin-directory-structure).\n\n### Test your plugins locally\n\nUse the `--plugin-dir` flag to test plugins during development. This loads your plugin directly without requiring installation.\n\n```bash theme={null}\nclaude --plugin-dir ./my-plugin\n```\n\nWhen a `--plugin-dir` plugin has the same name as an installed marketplace plugin, the local copy takes precedence for that session. This lets you test changes to a plugin you already have installed without uninstalling it first. Marketplace plugins force-enabled by managed settings are the only exception and cannot be overridden.\n\nAs you make changes to your plugin, run `/reload-plugins` to pick up the updates without restarting. Changes to LSP server configuration still require a full restart. Test your plugin components:\n\n* Try your skills with `/plugin-name:skill-name`\n* Check that agents appear in `/agents`\n* Verify hooks work as expected\n\n<Tip>\n You can load multiple plugins at once by specifying the flag multiple times:\n\n ```bash theme={null}\n claude --plugin-dir ./plugin-one --plugin-dir ./plugin-two\n ```\n</Tip>\n\n### Debug plugin issues\n\nIf your plugin isn't working as expected:\n\n1. **Check the structure**: Ensure your directories are at the plugin root, not inside `.claude-plugin/`\n2. **Test components individually**: Check each command, agent, and hook separately\n3. **Use validation and debugging tools**: See [Debugging and development tools](/en/plugins-reference#debugging-and-development-tools) for CLI commands and troubleshooting techniques\n\n### Share your plugins\n\nWhen your plugin is ready to share:\n\n1. **Add documentation**: Include a `README.md` with installation and usage instructions\n2. **Version your plugin**: Use [semantic versioning](/en/plugins-reference#version-management) in your `plugin.json`\n3. **Create or use a marketplace**: Distribute through [plugin marketplaces](/en/plugin-marketplaces) for installation\n4. **Test with others**: Have team members test the plugin before wider distribution\n\nOnce your plugin is in a marketplace, others can install it using the instructions in [Discover and install plugins](/en/discover-plugins).\n\n### Submit your plugin to the official marketplace\n\nTo submit a plugin to the official Anthropic marketplace, use one of the in-app submission forms:\n\n* **Claude.ai**: [claude.ai/settings/plugins/submit](https://claude.ai/settings/plugins/submit)\n* **Console**: [platform.claude.com/plugins/submit](https://platform.claude.com/plugins/submit)\n\n<Note>\n For complete technical specifications, debugging techniques, and distribution strategies, see [Plugins reference](/en/plugins-reference).\n</Note>\n\n## Convert existing configurations to plugins\n\nIf you already have skills or hooks in your `.claude/` directory, you can convert them into a plugin for easier sharing and distribution.\n\n### Migration steps\n\n<Steps>\n <Step title=\"Create the plugin structure\">\n Create a new plugin directory:\n\n ```bash theme={null}\n mkdir -p my-plugin/.claude-plugin\n ```\n\n Create the manifest file at `my-plugin/.claude-plugin/plugin.json`:\n\n ```json my-plugin/.claude-plugin/plugin.json theme={null}\n {\n \"name\": \"my-plugin\",\n \"description\": \"Migrated from standalone configuration\",\n \"version\": \"1.0.0\"\n }\n ```\n </Step>\n\n <Step title=\"Copy your existing files\">\n Copy your existing configurations to the plugin directory:\n\n ```bash theme={null}\n # Copy commands\n cp -r .claude/commands my-plugin/\n\n # Copy agents (if any)\n cp -r .claude/agents my-plugin/\n\n # Copy skills (if any)\n cp -r .claude/skills my-plugin/\n ```\n </Step>\n\n <Step title=\"Migrate hooks\">\n If you have hooks in your settings, create a hooks directory:\n\n ```bash theme={null}\n mkdir my-plugin/hooks\n ```\n\n Create `my-plugin/hooks/hooks.json` with your hooks configuration. Copy the `hooks` object from your `.claude/settings.json` or `settings.local.json`, since the format is the same. The command receives hook input as JSON on stdin, so use `jq` to extract the file path:\n\n ```json my-plugin/hooks/hooks.json theme={null}\n {\n \"hooks\": {\n \"PostToolUse\": [\n {\n \"matcher\": \"Write|Edit\",\n \"hooks\": [{ \"type\": \"command\", \"command\": \"jq -r '.tool_input.file_path' | xargs npm run lint:fix\" }]\n }\n ]\n }\n }\n ```\n </Step>\n\n <Step title=\"Test your migrated plugin\">\n Load your plugin to verify everything works:\n\n ```bash theme={null}\n claude --plugin-dir ./my-plugin\n ```\n\n Test each component: run your commands, check agents appear in `/agents`, and verify hooks trigger correctly.\n </Step>\n</Steps>\n\n### What changes when migrating\n\n| Standalone (`.claude/`) | Plugin |\n| :---------------------------- | :------------------------------- |\n| Only available in one project | Can be shared via marketplaces |\n| Files in `.claude/commands/` | Files in `plugin-name/commands/` |\n| Hooks in `settings.json` | Hooks in `hooks/hooks.json` |\n| Must manually copy to share | Install with `/plugin install` |\n\n<Note>\n After migrating, you can remove the original files from `.claude/` to avoid duplicates. The plugin version will take precedence when loaded.\n</Note>\n\n## Next steps\n\nNow that you understand Claude Code's plugin system, here are suggested paths for different goals:\n\n### For plugin users\n\n* [Discover and install plugins](/en/discover-plugins): browse marketplaces and install plugins\n* [Configure team marketplaces](/en/discover-plugins#configure-team-marketplaces): set up repository-level plugins for your team\n\n### For plugin developers\n\n* [Create and distribute a marketplace](/en/plugin-marketplaces): package and share your plugins\n* [Plugins reference](/en/plugins-reference): complete technical specifications\n* Dive deeper into specific plugin components:\n * [Skills](/en/skills): skill development details\n * [Subagents](/en/sub-agents): agent configuration and capabilities\n * [Hooks](/en/hooks): event handling and automation\n * [MCP](/en/mcp): external tool integration\n"

Skills are model-invoked: Claude automatically uses them based on the task context.\n\nAdd a `skills/` directory at your plugin root with Skill folders containing `SKILL.md` files:\n\n```text theme={null}\nmy-plugin/\n├── .claude-plugin/\n│ └── plugin.json\n└── skills/\n └── code-review/\n └── SKILL.md\n```\n\nEach `SKILL.md` needs frontmatter with `name` and `description` fields, followed by instructions:\n\n```yaml theme={null}\n---\nname: code-review\ndescription: Reviews code for best practices and potential issues. Use when reviewing code, checking PRs, or analyzing code quality.\n---\n\nWhen reviewing code, check for:\n1. Code organization and structure\n2. Error handling\n3. Security concerns\n4. Test coverage\n```\n\nAfter installing the plugin, run `/reload-plugins` to load the Skills. For complete Skill authoring guidance including progressive disclosure and tool restrictions, see [Agent Skills](/en/skills).\n\n### Add LSP servers to your plugin\n\n<Tip>\n For common languages like TypeScript, Python, and Rust, install the pre-built LSP plugins from the official marketplace. Create custom LSP plugins only when you need support for languages not already covered.\n</Tip>\n\nLSP (Language Server Protocol) plugins give Claude real-time code intelligence. If you need to support a language that doesn't have an official LSP plugin, you can create your own by adding an `.lsp.json` file to your plugin:\n\n```json .lsp.json theme={null}\n{\n \"go\": {\n \"command\": \"gopls\",\n \"args\": [\"serve\"],\n \"extensionToLanguage\": {\n \".go\": \"go\"\n }\n }\n}\n```\n\nUsers installing your plugin must have the language server binary installed on their machine.\n\nFor complete LSP configuration options, see [LSP servers](/en/plugins-reference#lsp-servers).\n\n### Ship default settings with your plugin\n\nPlugins can include a `settings.json` file at the plugin root to apply default configuration when the plugin is enabled. Currently, only the `agent` key is supported.\n\nSetting `agent` activates one of the plugin's [custom agents](/en/sub-agents) as the main thread, applying its system prompt, tool restrictions, and model. This lets a plugin change how Claude Code behaves by default when enabled.\n\n```json settings.json theme={null}\n{\n \"agent\": \"security-reviewer\"\n}\n```\n\nThis example activates the `security-reviewer` agent defined in the plugin's `agents/` directory. Settings from `settings.json` take priority over `settings` declared in `plugin.json`. Unknown keys are silently ignored.\n\n### Organize complex plugins\n\nFor plugins with many components, organize your directory structure by functionality. For complete directory layouts and organization patterns, see [Plugin directory structure](/en/plugins-reference#plugin-directory-structure).\n\n### Test your plugins locally\n\nUse the `--plugin-dir` flag to test plugins during development. This loads your plugin directly without requiring installation.\n\n```bash theme={null}\nclaude --plugin-dir ./my-plugin\n```\n\nWhen a `--plugin-dir` plugin has the same name as an installed marketplace plugin, the local copy takes precedence for that session. This lets you test changes to a plugin you already have installed without uninstalling it first. Marketplace plugins force-enabled by managed settings are the only exception and cannot be overridden.\n\nAs you make changes to your plugin, run `/reload-plugins` to pick up the updates without restarting. Changes to LSP server configuration still require a full restart. Test your plugin components:\n\n* Try your skills with `/plugin-name:skill-name`\n* Check that agents appear in `/agents`\n* Verify hooks work as expected\n\n<Tip>\n You can load multiple plugins at once by specifying the flag multiple times:\n\n ```bash theme={null}\n claude --plugin-dir ./plugin-one --plugin-dir ./plugin-two\n ```\n</Tip>\n\n### Debug plugin issues\n\nIf your plugin isn't working as expected:\n\n1. **Check the structure**: Ensure your directories are at the plugin root, not inside `.claude-plugin/`\n2. **Test components individually**: Check each command, agent, and hook separately\n3. **Use validation and debugging tools**: See [Debugging and development tools](/en/plugins-reference#debugging-and-development-tools) for CLI commands and troubleshooting techniques\n\n### Share your plugins\n\nWhen your plugin is ready to share:\n\n1. **Add documentation**: Include a `README.md` with installation and usage instructions\n2. **Version your plugin**: Use [semantic versioning](/en/plugins-reference#version-management) in your `plugin.json`\n3. **Create or use a marketplace**: Distribute through [plugin marketplaces](/en/plugin-marketplaces) for installation\n4. **Test with others**: Have team members test the plugin before wider distribution\n\nOnce your plugin is in a marketplace, others can install it using the instructions in [Discover and install plugins](/en/discover-plugins).\n\n### Submit your plugin to the official marketplace\n\nTo submit a plugin to the official Anthropic marketplace, use one of the in-app submission forms:\n\n* **Claude.ai**: [claude.ai/settings/plugins/submit](https://claude.ai/settings/plugins/submit)\n* **Console**: [platform.claude.com/plugins/submit](https://platform.claude.com/plugins/submit)\n\n<Note>\n For complete technical specifications, debugging techniques, and distribution strategies, see [Plugins reference](/en/plugins-reference).\n</Note>\n\n## Convert existing configurations to plugins\n\nIf you already have skills or hooks in your `.claude/` directory, you can convert them into a plugin for easier sharing and distribution.\n\n### Migration steps\n\n<Steps>\n <Step title=\"Create the plugin structure\">\n Create a new plugin directory:\n\n ```bash theme={null}\n mkdir -p my-plugin/.claude-plugin\n ```\n\n Create the manifest file at `my-plugin/.claude-plugin/plugin.json`:\n\n ```json my-plugin/.claude-plugin/plugin.json theme={null}\n {\n \"name\": \"my-plugin\",\n \"description\": \"Migrated from standalone configuration\",\n \"version\": \"1.0.0\"\n }\n ```\n </Step>\n\n <Step title=\"Copy your existing files\">\n Copy your existing configurations to the plugin directory:\n\n ```bash theme={null}\n # Copy commands\n cp -r .claude/commands my-plugin/\n\n # Copy agents (if any)\n cp -r .claude/agents my-plugin/\n\n # Copy skills (if any)\n cp -r .claude/skills my-plugin/\n ```\n </Step>\n\n <Step title=\"Migrate hooks\">\n If you have hooks in your settings, create a hooks directory:\n\n ```bash theme={null}\n mkdir my-plugin/hooks\n ```\n\n Create `my-plugin/hooks/hooks.json` with your hooks configuration. Copy the `hooks` object from your `.claude/settings.json` or `settings.local.json`, since the format is the same. The command receives hook input as JSON on stdin, so use `jq` to extract the file path:\n\n ```json my-plugin/hooks/hooks.json theme={null}\n {\n \"hooks\": {\n \"PostToolUse\": [\n {\n \"matcher\": \"Write|Edit\",\n \"hooks\": [{ \"type\": \"command\", \"command\": \"jq -r '.tool_input.file_path' | xargs npm run lint:fix\" }]\n }\n ]\n }\n }\n ```\n </Step>\n\n <Step title=\"Test your migrated plugin\">\n Load your plugin to verify everything works:\n\n ```bash theme={null}\n claude --plugin-dir ./my-plugin\n ```\n\n Test each component: run your commands, check agents appear in `/agents`, and verify hooks trigger correctly.\n </Step>\n</Steps>\n\n### What changes when migrating\n\n| Standalone (`.claude/`) | Plugin |\n| :---------------------------- | :------------------------------- |\n| Only available in one project | Can be shared via marketplaces |\n| Files in `.claude/commands/` | Files in `plugin-name/commands/` |\n| Hooks in `settings.json` | Hooks in `hooks/hooks.json` |\n| Must manually copy to share | Install with `/plugin install` |\n\n<Note>\n After migrating, you can remove the original files from `.claude/` to avoid duplicates. The plugin version will take precedence when loaded.\n</Note>\n\n## Next steps\n\nNow that you understand Claude Code's plugin system, here are suggested paths for different goals:\n\n### For plugin users\n\n* [Discover and install plugins](/en/discover-plugins): browse marketplaces and install plugins\n* [Configure team marketplaces](/en/discover-plugins#configure-team-marketplaces): set up repository-level plugins for your team\n\n### For plugin developers\n\n* [Create and distribute a marketplace](/en/plugin-marketplaces): package and share your plugins\n* [Plugins reference](/en/plugins-reference): complete technical specifications\n* Dive deeper into specific plugin components:\n * [Skills](/en/skills): skill development details\n * [Subagents](/en/sub-agents): agent configuration and capabilities\n * [Hooks](/en/hooks): event handling and automation\n * [MCP](/en/mcp): external tool integration\n",

"content": "# Playwright Skill for Claude Code: Overview\n\n## Core Functionality\n\nThe Playwright Skill is a Claude Code plugin designed as an alternative to the Playwright MCP server. Rather than sending accessibility tree snapshots with each action, the skill has Claude write Playwright code directly and execute it, returning only screenshots and console output.\n\n## Key Advantages Over Playwright MCP\n\n**Token Efficiency:** The original motivation was addressing the token consumption issue of Playwright MCP. The creator stated: \"I got tired of playwright-mcp eating through Claude's 200K token limit.\" This skill uses only 314 lines of instructions versus a persistent MCP server, with full API documentation loading only when needed.\n\n**Simplified Workflow:** Instead of continuous context updates, the skill operates on a cleaner cycle: Claude generates code → execution occurs → results (screenshots and console output) return to the model.\n\n## Installation & Usage\n\nThe skill works as either a Claude Code plugin or manual installation. It's built on Anthropic's new Claude Skills system and can be integrated into claude.ai through the capabilities settings.\n\n## Intended Use Cases\n\nThe creator clarified the appropriate scope: this tool suits \"scriptable manual testing\" during local development—quick validation like \"does my new feature work?\"—rather than comprehensive CI/CD test coverage. It's not designed to replace permanent test suites.\n\n## Privacy Considerations\n\nScreenshots remain local in `/tmp`, but console output and page content sent to Claude mean the tool requires dummy data, not production information with proprietary details."

The creator stated: \"I got tired of playwright-mcp eating through Claude's 200K token limit.\" This skill uses only 314 lines of instructions versus a persistent MCP server, with full API documentation loading only when needed.\n\n**Simplified Workflow:** Instead of continuous context updates, the skill operates on a cleaner cycle: Claude generates code → execution occurs → results (screenshots and console output) return to the model.\n\n## Installation & Usage\n\nThe skill works as either a Claude Code plugin or manual installation. It's built on Anthropic's new Claude Skills system and can be integrated into claude.ai through the capabilities settings.\n\n## Intended Use Cases\n\nThe creator clarified the appropriate scope: this tool suits \"scriptable manual testing\" during local development—quick validation like \"does my new feature work?\"—rather than comprehensive CI/CD test coverage. It's not designed to replace permanent test suites.\n\n## Privacy Considerations\n\nScreenshots remain local in `/tmp`, but console output and page content sent to Claude mean the tool requires dummy data, not production information with proprietary details.",

Plugin marketplaces are catalogs that help you discover and install these extensions without building them yourself.\n\nLooking to create and distribute your own marketplace? See [Create and distribute a plugin marketplace](/en/plugin-marketplaces).\n\n## How marketplaces work\n\nA marketplace is a catalog of plugins that someone else has created and shared. Using a marketplace is a two-step process:\n\n<Steps>\n <Step title=\"Add the marketplace\">\n This registers the catalog with Claude Code so you can browse what's available. No plugins are installed yet.\n </Step>\n\n <Step title=\"Install individual plugins\">\n Browse the catalog and install the plugins you want.\n </Step>\n</Steps>\n\nThink of it like adding an app store: adding the store gives you access to browse its collection, but you still choose which apps to download individually.\n\n## Official Anthropic marketplace\n\nThe official Anthropic marketplace (`claude-plugins-official`) is automatically available when you start Claude Code. Run `/plugin` and go to the **Discover** tab to browse what's available.\n\nTo install a plugin from the official marketplace:\n\n```shell theme={null}\n/plugin install plugin-name@claude-plugins-official\n```\n\n<Note>\n The official marketplace is maintained by Anthropic. To submit a plugin to the official marketplace, use one of the in-app submission forms:\n\n * **Claude.ai**: [claude.ai/settings/plugins/submit](https://claude.ai/settings/plugins/submit)\n * **Console**: [platform.claude.com/plugins/submit](https://platform.claude.com/plugins/submit)\n\n To distribute plugins independently, [create your own marketplace](/en/plugin-marketplaces) and share it with users.\n</Note>\n\nThe official marketplace includes several categories of plugins:\n\n### Code intelligence\n\nCode intelligence plugins enable Claude Code's built-in LSP tool, giving Claude the ability to jump to definitions, find references, and see type errors immediately after edits. These plugins configure [Language Server Protocol](https://microsoft.github.io/language-server-protocol/) connections, the same technology that powers VS Code's code intelligence.\n\nThese plugins require the language server binary to be installed on your system. If you already have a language server installed, Claude may prompt you to install the corresponding plugin when you open a project.\n\n| Language | Plugin | Binary required |\n| :--------- | :------------------ | :--------------------------- |\n| C/C++ | `clangd-lsp` | `clangd` |\n| C# | `csharp-lsp` | `csharp-ls` |\n| Go | `gopls-lsp` | `gopls` |\n| Java | `jdtls-lsp` | `jdtls` |\n| Kotlin | `kotlin-lsp` | `kotlin-language-server` |\n| Lua | `lua-lsp` | `lua-language-server` |\n| PHP | `php-lsp` | `intelephense` |\n| Python | `pyright-lsp` | `pyright-langserver` |\n| Rust | `rust-analyzer-lsp` | `rust-analyzer` |\n| Swift | `swift-lsp` | `sourcekit-lsp` |\n| TypeScript | `typescript-lsp` | `typescript-language-server` |\n\nYou can also [create your own LSP plugin](/en/plugins-reference#lsp-servers) for other languages.\n\n<Note>\n If you see `Executable not found in $PATH` in the `/plugin` Errors tab after installing a plugin, install the required binary from the table above.\n</Note>\n\n#### What Claude gains from code intelligence plugins\n\nOnce a code intelligence plugin is installed and its language server binary is available, Claude gains two capabilities:\n\n* **Automatic diagnostics**: after every file edit Claude makes, the language server analyzes the changes and reports errors and warnings back automatically. Claude sees type errors, missing imports, and syntax issues without needing to run a compiler or linter. If Claude introduces an error, it notices and fixes the issue in the same turn. This requires no configuration beyond installing the plugin. You can see diagnostics inline by pressing **Ctrl+O** when the \"diagnostics found\" indicator appears.\n* **Code navigation**: Claude can use the language server to jump to definitions, find references, get type info on hover, list symbols, find implementations, and trace call hierarchies. These operations give Claude more precise navigation than grep-based search, though availability may vary by language and environment.\n\nIf you run into issues, see [Code intelligence troubleshooting](#code-intelligence-issues).\n\n### External integrations\n\nThese plugins bundle pre-configured [MCP servers](/en/mcp) so you can connect Claude to external services without manual setup:\n\n* **Source control**: `github`, `gitlab`\n* **Project management**: `atlassian` (Jira/Confluence), `asana`, `linear`, `notion`\n* **Design**: `figma`\n* **Infrastructure**: `vercel`, `firebase`, `supabase`\n* **Communication**: `slack`\n* **Monitoring**: `sentry`\n\n### Development workflows\n\nPlugins that add commands and agents for common development tasks:\n\n* **commit-commands**: Git commit workflows including commit, push, and PR creation\n* **pr-review-toolkit**: Specialized agents for reviewing pull requests\n* **agent-sdk-dev**: Tools for building with the Claude Agent SDK\n* **plugin-dev**: Toolkit for creating your own plugins\n\n### Output styles\n\nCustomize how Claude responds:\n\n* **explanatory-output-style**: Educational insights about implementation choices\n* **learning-output-style**: Interactive learning mode for skill building\n\n## Try it: add the demo marketplace\n\nAnthropic also maintains a [demo plugins marketplace](https://github.com/anthropics/claude-code/tree/main/plugins) (`claude-code-plugins`) with example plugins that show what's possible with the plugin system. Unlike the official marketplace, you need to add this one manually.\n\n<Steps>\n <Step title=\"Add the marketplace\">\n From within Claude Code, run the `plugin marketplace add` command for the `anthropics/claude-code` marketplace:\n\n ```shell theme={null}\n /plugin marketplace add anthropics/claude-code\n ```\n\n This downloads the marketplace catalog and makes its plugins available to you.\n </Step>\n\n <Step title=\"Browse available plugins\">\n Run `/plugin` to open the plugin manager. This opens a tabbed interface with four tabs you can cycle through using **Tab** (or **Shift+Tab** to go backward):\n\n * **Discover**: browse available plugins from all your marketplaces\n * **Installed**: view and manage your installed plugins\n * **Marketplaces**: add, remove, or update your added marketplaces\n * **Errors**: view any plugin loading errors\n\n Go to the **Discover** tab to see plugins from the marketplace you just added.\n </Step>\n\n <Step title=\"Install a plugin\">\n Select a plugin to view its details, then choose an installation scope:\n\n * **User scope**: install for yourself across all projects\n * **Project scope**: install for all collaborators on this repository\n * **Local scope**: install for yourself in this repository only\n\n For example, select **commit-commands** (a plugin that adds git workflow commands) and install it to your user scope.\n\n You can also install directly from the command line:\n\n ```shell theme={null}\n /plugin install commit-commands@anthropics-claude-code\n ```\n\n See [Configuration scopes](/en/settings#configuration-scopes) to learn more about scopes.\n </Step>\n\n <Step title=\"Use your new plugin\">\n After installing, the plugin's commands are immediately available. Plugin commands are namespaced by the plugin name, so **commit-commands** provides commands like `/commit-commands:commit`.\n\n Try it out by making a change to a file and running:\n\n ```shell theme={null}\n /commit-commands:commit\n ```\n\n This stages your changes, generates a commit message, and creates the commit.\n\n Each plugin works differently. Check the plugin's description in the **Discover** tab or its homepage to learn what commands and capabilities it provides.\n </Step>\n</Steps>\n\nThe rest of this guide covers all the ways you can add marketplaces, install plugins, and manage your configuration.\n\n## Add marketplaces\n\nUse the `/plugin marketplace add` command to add marketplaces from different sources.\n\n<Tip>\n **Shortcuts**: You can use `/plugin market` instead of `/plugin marketplace`, and `rm` instead of `remove`.\n</Tip>\n\n* **GitHub repositories**: `owner/repo` format (for example, `anthropics/claude-code`)\n* **Git URLs**: any git repository URL (GitLab, Bitbucket, self-hosted)\n* **Local paths**: directories or direct paths to `marketplace.json` files\n* **Remote URLs**: direct URLs to hosted `marketplace.json` files\n\n### Add from GitHub\n\nAdd a GitHub repository that contains a `.claude-plugin/marketplace.json` file using the `owner/repo` format—where `owner` is the GitHub username or organization and `repo` is the repository name.\n\nFor example, `anthropics/claude-code` refers to the `claude-code` repository owned by `anthropics`:\n\n```shell theme={null}\n/plugin marketplace add anthropics/claude-code\n```\n\n### Add from other Git hosts\n\nAdd any git repository by providing the full URL. This works with any Git host, including GitLab, Bitbucket, and self-hosted servers:\n\nUsing HTTPS:\n\n```shell theme={null}\n/plugin marketplace add https://gitlab.com/company/plugins.git\n```\n\nUsing SSH:\n\n```shell theme={null}\n/plugin marketplace add git@gitlab.com:company/plugins.git\n```\n\nTo add a specific branch or tag, append `#` followed by the ref:\n\n```shell theme={null}\n/plugin marketplace add https://gitlab.com/company/plugins.git#v1.0.0\n```\n\n### Add from local paths\n\nAdd a local directory that contains a `.claude-plugin/marketplace.json` file:\n\n```shell theme={null}\n/plugin marketplace add ./my-marketplace\n```\n\nYou can also add a direct path to a `marketplace.json` file:\n\n```shell theme={null}\n/plugin marketplace add ./path/to/marketplace.json\n```\n\n### Add from remote URLs\n\nAdd a remote `marketplace.json` file via URL:\n\n```shell theme={null}\n/plugin marketplace add https://example.com/marketplace.json\n```\n\n<Note>\n URL-based marketplaces have some limitations compared to Git-based marketplaces. If you encounter \"path not found\" errors when installing plugins, see [Troubleshooting](/en/plugin-marketplaces#plugins-with-relative-paths-fail-in-url-based-marketplaces).\n</Note>\n\n## Install plugins\n\nOnce you've added marketplaces, you can install plugins directly (installs to user scope by default):\n\n```shell theme={null}\n/plugin install plugin-name@marketplace-name\n```\n\nTo choose a different [installation scope](/en/settings#configuration-scopes), use the interactive UI: run `/plugin`, go to the **Discover** tab, and press **Enter** on a plugin. You'll see options for:\n\n* **User scope** (default): install for yourself across all projects\n* **Project scope**: install for all collaborators on this repository (adds to `.claude/settings.json`)\n* **Local scope**: install for yourself in this repository only (not shared with collaborators)\n\nYou may also see plugins with **managed** scope—these are installed by administrators via [managed settings](/en/settings#settings-files) and cannot be modified.\n\nRun `/plugin` and go to the **Installed** tab to see your plugins grouped by scope.\n\n<Warning>\n Make sure you trust a plugin before installing it. Anthropic does not control what MCP servers, files, or other software are included in plugins and cannot verify that they work as intended. Check each plugin's homepage for more information.\n</Warning>\n\n## Manage installed plugins\n\nRun `/plugin` and go to the **Installed** tab to view, enable, disable, or uninstall your plugins. Type to filter the list by plugin name or description.\n\nYou can also manage plugins with direct commands.\n\nDisable a plugin without uninstalling:\n\n```shell theme={null}\n/plugin disable plugin-name@marketplace-name\n```\n\nRe-enable a disabled plugin:\n\n```shell theme={null}\n/plugin enable plugin-name@marketplace-name\n```\n\nCompletely remove a plugin:\n\n```shell theme={null}\n/plugin uninstall plugin-name@marketplace-name\n```\n\nThe `--scope` option lets you target a specific scope with CLI commands:\n\n```shell theme={null}\nclaude plugin install formatter@your-org --scope project\nclaude plugin uninstall formatter@your-org --scope project\n```\n\n### Apply plugin changes without restarting\n\nWhen you install, enable, or disable plugins during a session, some changes (like new commands and hooks) take effect immediately. Others, including LSP server updates, require a restart.\n\nTo activate all pending plugin changes without restarting, run:\n\n```shell theme={null}\n/reload-plugins\n```\n\nClaude Code reloads all active plugins and reports what was loaded. If any LSP servers were added or updated, it will let you know those require a restart to take effect.\n\n## Manage marketplaces\n\nYou can manage marketplaces through the interactive `/plugin` interface or with CLI commands.\n\n### Use the interactive interface\n\nRun `/plugin` and go to the **Marketplaces** tab to:\n\n* View all your added marketplaces with their sources and status\n* Add new marketplaces\n* Update marketplace listings to fetch the latest plugins\n* Remove marketplaces you no longer need\n\n### Use CLI commands\n\nYou can also manage marketplaces with direct commands.\n\nList all configured marketplaces:\n\n```shell theme={null}\n/plugin marketplace list\n```\n\nRefresh plugin listings from a marketplace:\n\n```shell theme={null}\n/plugin marketplace update marketplace-name\n```\n\nRemove a marketplace:\n\n```shell theme={null}\n/plugin marketplace remove marketplace-name\n```\n\n<Warning>\n Removing a marketplace will uninstall any plugins you installed from it.\n</Warning>\n\n### Configure auto-updates\n\nClaude Code can automatically update marketplaces and their installed plugins at startup. When auto-update is enabled for a marketplace, Claude Code refreshes the marketplace data and updates installed plugins to their latest versions. If any plugins were updated, you'll see a notification prompting you to run `/reload-plugins`.\n\nToggle auto-update for individual marketplaces through the UI:\n\n1. Run `/plugin` to open the plugin manager\n2. Select **Marketplaces**\n3. Choose a marketplace from the list\n4. Select **Enable auto-update** or **Disable auto-update**\n\nOfficial Anthropic marketplaces have auto-update enabled by default. Third-party and local development marketplaces have auto-update disabled by default.\n\nTo disable all automatic updates entirely for both Claude Code and all plugins, set the `DISABLE_AUTOUPDATER` environment variable. See [Auto updates](/en/setup#auto-updates) for details.\n\nTo keep plugin auto-updates enabled while disabling Claude Code auto-updates, set `FORCE_AUTOUPDATE_PLUGINS=true` along with `DISABLE_AUTOUPDATER`:\n\n```shell theme={null}\nexport DISABLE_AUTOUPDATER=true\nexport FORCE_AUTOUPDATE_PLUGINS=true\n```\n\nThis is useful when you want to manage Claude Code updates manually but still receive automatic plugin updates.\n\n## Configure team marketplaces\n\nTeam admins can set up automatic marketplace installation for projects by adding marketplace configuration to `.claude/settings.json`. When team members trust the repository folder, Claude Code prompts them to install these marketplaces and plugins.\n\nAdd `extraKnownMarketplaces` to your project's `.claude/settings.json`:\n\n```json theme={null}\n{\n \"extraKnownMarketplaces\": {\n \"my-team-tools\": {\n \"source\": {\n \"source\": \"github\",\n \"repo\": \"your-org/claude-plugins\"\n }\n }\n }\n}\n```\n\nFor full configuration options including `extraKnownMarketplaces` and `enabledPlugins`, see [Plugin settings](/en/settings#plugin-settings).\n\n## Security\n\nPlugins and marketplaces are highly trusted components that can execute arbitrary code on your machine with your user privileges. Only install plugins and add marketplaces from sources you trust. Organizations can restrict which marketplaces users are allowed to add using [managed marketplace restrictions](/en/plugin-marketplaces#managed-marketplace-restrictions).\n\n## Troubleshooting\n\n### /plugin command not recognized\n\nIf you see \"unknown command\" or the `/plugin` command doesn't appear:\n\n1. **Check your version**: Run `claude --version`. Plugins require version 1.0.33 or later.\n2. **Update Claude Code**:\n * **Homebrew**: `brew upgrade claude-code`\n * **npm**: `npm update -g @anthropic-ai/claude-code`\n * **Native installer**: Re-run the install command from [Setup](/en/setup)\n3. **Restart Claude Code**: After updating, restart your terminal and run `claude` again.\n\n### Common issues\n\n* **Marketplace not loading**: Verify the URL is accessible and that `.claude-plugin/marketplace.json` exists at the path\n* **Plugin installation failures**: Check that plugin source URLs are accessible and repositories are public (or you have access)\n* **Files not found after installation**: Plugins are copied to a cache, so paths referencing files outside the plugin directory won't work\n* **Plugin skills not appearing**: Clear the cache with `rm -rf ~/.claude/plugins/cache`, restart Claude Code, and reinstall the plugin.\n\nFor detailed troubleshooting with solutions, see [Troubleshooting](/en/plugin-marketplaces#troubleshooting) in the marketplace guide. For debugging tools, see [Debugging and development tools](/en/plugins-reference#debugging-and-development-tools).\n\n### Code intelligence issues\n\n* **Language server not starting**: verify the binary is installed and available in your `$PATH`. Check the `/plugin` Errors tab for details.\n* **High memory usage**: language servers like `rust-analyzer` and `pyright` can consume significant memory on large projects. If you experience memory issues, disable the plugin with `/plugin disable <plugin-name>` and rely on Claude's built-in search tools instead.\n* **False positive diagnostics in monorepos**: language servers may report unresolved import errors for internal packages if the workspace isn't configured correctly. These don't affect Claude's ability to edit code.\n\n## Next steps\n\n* **Build your own plugins**: See [Plugins](/en/plugins) to create skills, agents, and hooks\n* **Create a marketplace**: See [Create a plugin marketplace](/en/plugin-marketplaces) to distribute plugins to your team or community\n* **Technical reference**: See [Plugins reference](/en/plugins-reference) for complete specifications\n"

Plugin marketplaces are catalogs that help you discover and install these extensions without building them yourself.\n\nLooking to create and distribute your own marketplace? See [Create and distribute a plugin marketplace](/en/plugin-marketplaces).\n\n## How marketplaces work\n\nA marketplace is a catalog of plugins that someone else has created and shared. Using a marketplace is a two-step process:\n\n<Steps>\n <Step title=\"Add the marketplace\">\n This registers the catalog with Claude Code so you can browse what's available. No plugins are installed yet.\n </Step>\n\n <Step title=\"Install individual plugins\">\n Browse the catalog and install the plugins you want.\n </Step>\n</Steps>\n\nThink of it like adding an app store: adding the store gives you access to browse its collection, but you still choose which apps to download individually.\n\n## Official Anthropic marketplace\n\nThe official Anthropic marketplace (`claude-plugins-official`) is automatically available when you start Claude Code. Run `/plugin` and go to the **Discover** tab to browse what's available.\n\nTo install a plugin from the official marketplace:\n\n```shell theme={null}\n/plugin install plugin-name@claude-plugins-official\n```\n\n<Note>\n The official marketplace is maintained by Anthropic. To submit a plugin to the official marketplace, use one of the in-app submission forms:\n\n * **Claude.ai**: [claude.ai/settings/plugins/submit](https://claude.ai/settings/plugins/submit)\n * **Console**: [platform.claude.com/plugins/submit](https://platform.claude.com/plugins/submit)\n\n To distribute plugins independently, [create your own marketplace](/en/plugin-marketplaces) and share it with users.\n</Note>\n\nThe official marketplace includes several categories of plugins:\n\n### Code intelligence\n\nCode intelligence plugins enable Claude Code's built-in LSP tool, giving Claude the ability to jump to definitions, find references, and see type errors immediately after edits. These plugins configure [Language Server Protocol](https://microsoft.github.io/language-server-protocol/) connections, the same technology that powers VS Code's code intelligence.\n\nThese plugins require the language server binary to be installed on your system. If you already have a language server installed, Claude may prompt you to install the corresponding plugin when you open a project.\n\n| Language | Plugin | Binary required |\n| :--------- | :------------------ | :--------------------------- |\n| C/C++ | `clangd-lsp` | `clangd` |\n| C# | `csharp-lsp` | `csharp-ls` |\n| Go | `gopls-lsp` | `gopls` |\n| Java | `jdtls-lsp` | `jdtls` |\n| Kotlin | `kotlin-lsp` | `kotlin-language-server` |\n| Lua | `lua-lsp` | `lua-language-server` |\n| PHP | `php-lsp` | `intelephense` |\n| Python | `pyright-lsp` | `pyright-langserver` |\n| Rust | `rust-analyzer-lsp` | `rust-analyzer` |\n| Swift | `swift-lsp` | `sourcekit-lsp` |\n| TypeScript | `typescript-lsp` | `typescript-language-server` |\n\nYou can also [create your own LSP plugin](/en/plugins-reference#lsp-servers) for other languages.\n\n<Note>\n If you see `Executable not found in $PATH` in the `/plugin` Errors tab after installing a plugin, install the required binary from the table above.\n</Note>\n\n#### What Claude gains from code intelligence plugins\n\nOnce a code intelligence plugin is installed and its language server binary is available, Claude gains two capabilities:\n\n* **Automatic diagnostics**: after every file edit Claude makes, the language server analyzes the changes and reports errors and warnings back automatically. Claude sees type errors, missing imports, and syntax issues without needing to run a compiler or linter. If Claude introduces an error, it notices and fixes the issue in the same turn. This requires no configuration beyond installing the plugin. You can see diagnostics inline by pressing **Ctrl+O** when the \"diagnostics found\" indicator appears.\n* **Code navigation**: Claude can use the language server to jump to definitions, find references, get type info on hover, list symbols, find implementations, and trace call hierarchies. These operations give Claude more precise navigation than grep-based search, though availability may vary by language and environment.\n\nIf you run into issues, see [Code intelligence troubleshooting](#code-intelligence-issues).\n\n### External integrations\n\nThese plugins bundle pre-configured [MCP servers](/en/mcp) so you can connect Claude to external services without manual setup:\n\n* **Source control**: `github`, `gitlab`\n* **Project management**: `atlassian` (Jira/Confluence), `asana`, `linear`, `notion`\n* **Design**: `figma`\n* **Infrastructure**: `vercel`, `firebase`, `supabase`\n* **Communication**: `slack`\n* **Monitoring**: `sentry`\n\n### Development workflows\n\nPlugins that add commands and agents for common development tasks:\n\n* **commit-commands**: Git commit workflows including commit, push, and PR creation\n* **pr-review-toolkit**: Specialized agents for reviewing pull requests\n* **agent-sdk-dev**: Tools for building with the Claude Agent SDK\n* **plugin-dev**: Toolkit for creating your own plugins\n\n### Output styles\n\nCustomize how Claude responds:\n\n* **explanatory-output-style**: Educational insights about implementation choices\n* **learning-output-style**: Interactive learning mode for skill building\n\n## Try it: add the demo marketplace\n\nAnthropic also maintains a [demo plugins marketplace](https://github.com/anthropics/claude-code/tree/main/plugins) (`claude-code-plugins`) with example plugins that show what's possible with the plugin system. Unlike the official marketplace, you need to add this one manually.\n\n<Steps>\n <Step title=\"Add the marketplace\">\n From within Claude Code, run the `plugin marketplace add` command for the `anthropics/claude-code` marketplace:\n\n ```shell theme={null}\n /plugin marketplace add anthropics/claude-code\n ```\n\n This downloads the marketplace catalog and makes its plugins available to you.\n </Step>\n\n <Step title=\"Browse available plugins\">\n Run `/plugin` to open the plugin manager. This opens a tabbed interface with four tabs you can cycle through using **Tab** (or **Shift+Tab** to go backward):\n\n * **Discover**: browse available plugins from all your marketplaces\n * **Installed**: view and manage your installed plugins\n * **Marketplaces**: add, remove, or update your added marketplaces\n * **Errors**: view any plugin loading errors\n\n Go to the **Discover** tab to see plugins from the marketplace you just added.\n </Step>\n\n <Step title=\"Install a plugin\">\n Select a plugin to view its details, then choose an installation scope:\n\n * **User scope**: install for yourself across all projects\n * **Project scope**: install for all collaborators on this repository\n * **Local scope**: install for yourself in this repository only\n\n For example, select **commit-commands** (a plugin that adds git workflow commands) and install it to your user scope.\n\n You can also install directly from the command line:\n\n ```shell theme={null}\n /plugin install commit-commands@anthropics-claude-code\n ```\n\n See [Configuration scopes](/en/settings#configuration-scopes) to learn more about scopes.\n </Step>\n\n <Step title=\"Use your new plugin\">\n After installing, the plugin's commands are immediately available. Plugin commands are namespaced by the plugin name, so **commit-commands** provides commands like `/commit-commands:commit`.\n\n Try it out by making a change to a file and running:\n\n ```shell theme={null}\n /commit-commands:commit\n ```\n\n This stages your changes, generates a commit message, and creates the commit.\n\n Each plugin works differently. Check the plugin's description in the **Discover** tab or its homepage to learn what commands and capabilities it provides.\n </Step>\n</Steps>\n\nThe rest of this guide covers all the ways you can add marketplaces, install plugins, and manage your configuration.\n\n## Add marketplaces\n\nUse the `/plugin marketplace add` command to add marketplaces from different sources.\n\n<Tip>\n **Shortcuts**: You can use `/plugin market` instead of `/plugin marketplace`, and `rm` instead of `remove`.\n</Tip>\n\n* **GitHub repositories**: `owner/repo` format (for example, `anthropics/claude-code`)\n* **Git URLs**: any git repository URL (GitLab, Bitbucket, self-hosted)\n* **Local paths**: directories or direct paths to `marketplace.json` files\n* **Remote URLs**: direct URLs to hosted `marketplace.json` files\n\n### Add from GitHub\n\nAdd a GitHub repository that contains a `.claude-plugin/marketplace.json` file using the `owner/repo` format—where `owner` is the GitHub username or organization and `repo` is the repository name.\n\nFor example, `anthropics/claude-code` refers to the `claude-code` repository owned by `anthropics`:\n\n```shell theme={null}\n/plugin marketplace add anthropics/claude-code\n```\n\n### Add from other Git hosts\n\nAdd any git repository by providing the full URL. This works with any Git host, including GitLab, Bitbucket, and self-hosted servers:\n\nUsing HTTPS:\n\n```shell theme={null}\n/plugin marketplace add https://gitlab.com/company/plugins.git\n```\n\nUsing SSH:\n\n```shell theme={null}\n/plugin marketplace add git@gitlab.com:company/plugins.git\n```\n\nTo add a specific branch or tag, append `#` followed by the ref:\n\n```shell theme={null}\n/plugin marketplace add https://gitlab.com/company/plugins.git#v1.0.0\n```\n\n### Add from local paths\n\nAdd a local directory that contains a `.claude-plugin/marketplace.json` file:\n\n```shell theme={null}\n/plugin marketplace add ./my-marketplace\n```\n\nYou can also add a direct path to a `marketplace.json` file:\n\n```shell theme={null}\n/plugin marketplace add ./path/to/marketplace.json\n```\n\n### Add from remote URLs\n\nAdd a remote `marketplace.json` file via URL:\n\n```shell theme={null}\n/plugin marketplace add https://example.com/marketplace.json\n```\n\n<Note>\n URL-based marketplaces have some limitations compared to Git-based marketplaces. If you encounter \"path not found\" errors when installing plugins, see [Troubleshooting](/en/plugin-marketplaces#plugins-with-relative-paths-fail-in-url-based-marketplaces).\n</Note>\n\n## Install plugins\n\nOnce you've added marketplaces, you can install plugins directly (installs to user scope by default):\n\n```shell theme={null}\n/plugin install plugin-name@marketplace-name\n```\n\nTo choose a different [installation scope](/en/settings#configuration-scopes), use the interactive UI: run `/plugin`, go to the **Discover** tab, and press **Enter** on a plugin. You'll see options for:\n\n* **User scope** (default): install for yourself across all projects\n* **Project scope**: install for all collaborators on this repository (adds to `.claude/settings.json`)\n* **Local scope**: install for yourself in this repository only (not shared with collaborators)\n\nYou may also see plugins with **managed** scope—these are installed by administrators via [managed settings](/en/settings#settings-files) and cannot be modified.\n\nRun `/plugin` and go to the **Installed** tab to see your plugins grouped by scope.\n\n<Warning>\n Make sure you trust a plugin before installing it. Anthropic does not control what MCP servers, files, or other software are included in plugins and cannot verify that they work as intended. Check each plugin's homepage for more information.\n</Warning>\n\n## Manage installed plugins\n\nRun `/plugin` and go to the **Installed** tab to view, enable, disable, or uninstall your plugins. Type to filter the list by plugin name or description.\n\nYou can also manage plugins with direct commands.\n\nDisable a plugin without uninstalling:\n\n```shell theme={null}\n/plugin disable plugin-name@marketplace-name\n```\n\nRe-enable a disabled plugin:\n\n```shell theme={null}\n/plugin enable plugin-name@marketplace-name\n```\n\nCompletely remove a plugin:\n\n```shell theme={null}\n/plugin uninstall plugin-name@marketplace-name\n```\n\nThe `--scope` option lets you target a specific scope with CLI commands:\n\n```shell theme={null}\nclaude plugin install formatter@your-org --scope project\nclaude plugin uninstall formatter@your-org --scope project\n```\n\n### Apply plugin changes without restarting\n\nWhen you install, enable, or disable plugins during a session, some changes (like new commands and hooks) take effect immediately. Others, including LSP server updates, require a restart.\n\nTo activate all pending plugin changes without restarting, run:\n\n```shell theme={null}\n/reload-plugins\n```\n\nClaude Code reloads all active plugins and reports what was loaded. If any LSP servers were added or updated, it will let you know those require a restart to take effect.\n\n## Manage marketplaces\n\nYou can manage marketplaces through the interactive `/plugin` interface or with CLI commands.\n\n### Use the interactive interface\n\nRun `/plugin` and go to the **Marketplaces** tab to:\n\n* View all your added marketplaces with their sources and status\n* Add new marketplaces\n* Update marketplace listings to fetch the latest plugins\n* Remove marketplaces you no longer need\n\n### Use CLI commands\n\nYou can also manage marketplaces with direct commands.\n\nList all configured marketplaces:\n\n```shell theme={null}\n/plugin marketplace list\n```\n\nRefresh plugin listings from a marketplace:\n\n```shell theme={null}\n/plugin marketplace update marketplace-name\n```\n\nRemove a marketplace:\n\n```shell theme={null}\n/plugin marketplace remove marketplace-name\n```\n\n<Warning>\n Removing a marketplace will uninstall any plugins you installed from it.\n</Warning>\n\n### Configure auto-updates\n\nClaude Code can automatically update marketplaces and their installed plugins at startup. When auto-update is enabled for a marketplace, Claude Code refreshes the marketplace data and updates installed plugins to their latest versions. If any plugins were updated, you'll see a notification prompting you to run `/reload-plugins`.\n\nToggle auto-update for individual marketplaces through the UI:\n\n1. Run `/plugin` to open the plugin manager\n2. Select **Marketplaces**\n3. Choose a marketplace from the list\n4. Select **Enable auto-update** or **Disable auto-update**\n\nOfficial Anthropic marketplaces have auto-update enabled by default. Third-party and local development marketplaces have auto-update disabled by default.\n\nTo disable all automatic updates entirely for both Claude Code and all plugins, set the `DISABLE_AUTOUPDATER` environment variable. See [Auto updates](/en/setup#auto-updates) for details.\n\nTo keep plugin auto-updates enabled while disabling Claude Code auto-updates, set `FORCE_AUTOUPDATE_PLUGINS=true` along with `DISABLE_AUTOUPDATER`:\n\n```shell theme={null}\nexport DISABLE_AUTOUPDATER=true\nexport FORCE_AUTOUPDATE_PLUGINS=true\n```\n\nThis is useful when you want to manage Claude Code updates manually but still receive automatic plugin updates.\n\n## Configure team marketplaces\n\nTeam admins can set up automatic marketplace installation for projects by adding marketplace configuration to `.claude/settings.json`. When team members trust the repository folder, Claude Code prompts them to install these marketplaces and plugins.\n\nAdd `extraKnownMarketplaces` to your project's `.claude/settings.json`:\n\n```json theme={null}\n{\n \"extraKnownMarketplaces\": {\n \"my-team-tools\": {\n \"source\": {\n \"source\": \"github\",\n \"repo\": \"your-org/claude-plugins\"\n }\n }\n }\n}\n```\n\nFor full configuration options including `extraKnownMarketplaces` and `enabledPlugins`, see [Plugin settings](/en/settings#plugin-settings).\n\n## Security\n\nPlugins and marketplaces are highly trusted components that can execute arbitrary code on your machine with your user privileges. Only install plugins and add marketplaces from sources you trust. Organizations can restrict which marketplaces users are allowed to add using [managed marketplace restrictions](/en/plugin-marketplaces#managed-marketplace-restrictions).\n\n## Troubleshooting\n\n### /plugin command not recognized\n\nIf you see \"unknown command\" or the `/plugin` command doesn't appear:\n\n1. **Check your version**: Run `claude --version`. Plugins require version 1.0.33 or later.\n2. **Update Claude Code**:\n * **Homebrew**: `brew upgrade claude-code`\n * **npm**: `npm update -g @anthropic-ai/claude-code`\n * **Native installer**: Re-run the install command from [Setup](/en/setup)\n3. **Restart Claude Code**: After updating, restart your terminal and run `claude` again.\n\n### Common issues\n\n* **Marketplace not loading**: Verify the URL is accessible and that `.claude-plugin/marketplace.json` exists at the path\n* **Plugin installation failures**: Check that plugin source URLs are accessible and repositories are public (or you have access)\n* **Files not found after installation**: Plugins are copied to a cache, so paths referencing files outside the plugin directory won't work\n* **Plugin skills not appearing**: Clear the cache with `rm -rf ~/.claude/plugins/cache`, restart Claude Code, and reinstall the plugin.\n\nFor detailed troubleshooting with solutions, see [Troubleshooting](/en/plugin-marketplaces#troubleshooting) in the marketplace guide.

For most Claude Code CLI users, the **MCP approach is currently the recommended default**, while the CLI + Skills approach offers advantages for high-throughput, token-efficient scenarios.\n 18→\n 19→---\n 20→\n 21→## The Question\n 22→\n 23→The issue asks:\n 24→\n 25→> Do we actually use all these with `--tool claude`? Is there any better practices in the internet?\n 26→>\n 27→> ```\n 28→> playwright-cli install --skills\n 29→> claude mcp add playwright npx @playwright/mcp@latest\n 30→> ```\n 31→\n 32→### Analysis of the Commands\n 33→\n 34→1. **`playwright-cli install --skills`**: This command installs Skills documentation files to `~/.skills/playwright-cli/` for coding agents to understand and use playwright-cli commands efficiently.\n 35→\n 36→2. **`claude mcp add playwright npx @playwright/mcp@latest`**: This command registers the official Microsoft Playwright MCP server with Claude Code, enabling browser automation tools.\n 37→\n 38→**Important Clarification**: The `--tool claude` flag is **not a valid flag** for either command. The commands mentioned in the issue work independently.\n 39→\n 40→---\n 41→\n 42→## Two Approaches: MCP vs CLI + Skills\n 43→\n 44→### Approach 1: Playwright MCP Server (Recommended for Most Users)\n 45→\n 46→**Installation**:\n 47→\n 48→```bash\n 49→claude mcp add playwright npx @playwright/mcp@latest\n 50→```\n 51→\n 52→**How it works**:\n 53→\n 54→- Registers the official Microsoft Playwright MCP server with Claude Code\n 55→- Provides 25+ browser automation tools directly accessible to Claude\n 56→- Uses the Model Context Protocol standard developed by Anthropic\n 57→\n 58→**Key Features**:\n 59→\n 60→- Real-time browser control through accessibility snapshots\n 61→- Visible browser window for authentication and debugging\n 62→- Session persistence with cookies and local storage\n 63→- Extensive configuration options (headless mode, viewport, proxy, etc.)\n 64→\n 65→**Available Tools** (partial list):\n 66→\n 67→- `browser_navigate`, `browser_navigate_back`\n 68→- `browser_click`, `browser_type`, `browser_drag`\n 69→- `browser_take_screenshot`, `browser_snapshot`\n 70→- `browser_fill_form`, `browser_select_option`\n 71→- `browser_wait_for`, `browser_tabs`\n 72→- `browser_evaluate`, `browser_run_code`\n 73→\n 74→### Approach 2: Playwright CLI + Skills\n 75→\n 76→**Installation**:\n 77→\n 78→```bash\n 79→npm install -g @playwright/cli@latest\n 80→playwright-cli install --skills\n 81→```\n 82→\n 83→**How it works**:\n 84→\n 85→- Installs Skills documentation to `~/.skills/playwright-cli/`\n 86→- Claude Code reads these skill files for command understanding\n 87→- CLI commands are invoked directly without an MCP server\n 88→\n 89→**Key Features**:\n 90→\n 91→- More token-efficient (avoids loading large tool schemas)\n 92→- Works offline with static documentation\n 93→- 40+ CLI commands across browser control, interaction, storage, network\n 94→- Session management for parallel workflows\n 95→\n 96→---\n 97→\n 98→## Comparative Analysis\n 99→\n 100→### Feature Comparison\n 101→\n 102→| Feature | MCP Approach | CLI + Skills Approach |\n 103→| --------------------- | -------------------------- | ----------------------------- |\n 104→| **Setup Complexity** | Low (single command) | Medium (two commands) |\n 105→| **Token Efficiency** | Lower (loads tool schemas) | Higher (33% savings reported) |\n 106→| **Real-time Control** | Yes | Yes |\n 107→| **Offline Support** | No | Yes (Skills are static) |\n 108→| **Tool Discovery** | Automatic | Via `--help` or Skills docs |\n 109→| **Maintenance** | Automatic with @latest | Manual CLI updates |\n 110→| **Authentication** | Easy (visible browser) | Same capability |\n 111→| **CI/CD Integration** | Good | Better |\n 112→\n 113→### Performance Metrics\n 114→\n 115→According to benchmarks and research:\n 116→\n 117→- **MCP**: Provides \"70% memory reduction\" through accessibility trees vs screenshots\n 118→- **CLI + Skills**: Offers \"33% token savings\" in developer tasks due to avoided schema loading\n 119→\n 120→### Use Case Recommendations\n 121→\n 122→**Choose MCP when**:\n 123→\n 124→- You want the simplest setup\n 125→- You need real-time browser interaction\n 126→- You're doing exploratory testing or debugging\n 127→- Authentication through visible browser is valuable\n 128→- You prefer automatic tool discovery\n 129→\n 130→**Choose CLI + Skills when**:\n 131→\n 132→- Token efficiency is critical (large codebases)\n 133→- You need offline capability\n 134→- CI/CD pipeline integration is important\n 135→- You want explicit control over commands\n 136→- High-throughput automation is required\n 137→\n 138→---\n 139→\n 140→## Best Practices\n 141→\n 142→### For MCP Approach\n 143→\n 144→1. **Installation**:\n 145→\n 146→ ```bash\n 147→ #

"content": "# Case Study: Playwright MCP Best Practices for Claude Code CLI\n\n## Issue Reference\n\n- **Issue**: https://github.com/link-assistant/hive-mind/issues/1284\n- **Date**: 2026-02-13\n- **Tags**: documentation, enhancement, question\n- **Author**: konard\n\n## Executive Summary\n\nThis case study investigates the best practices for using Playwright with Claude Code CLI, comparing two primary approaches:\n\n1. **MCP (Model Context Protocol)**: `claude mcp add playwright npx @playwright/mcp@latest`\n2. **CLI + Skills**: `playwright-cli install --skills`\n\nOur research concludes that **both approaches have valid use cases**, and the optimal choice depends on the specific workflow requirements. For most Claude Code CLI users, the **MCP approach is currently the recommended default**, while the CLI + Skills approach offers advantages for high-throughput, token-efficient scenarios.\n\n---\n\n## The Question\n\nThe issue asks:\n\n> Do we actually use all these with `--tool claude`? Is there any better practices in the internet?\n>\n> ```\n> playwright-cli install --skills\n> claude mcp add playwright npx @playwright/mcp@latest\n> ```\n\n### Analysis of the Commands\n\n1. **`playwright-cli install --skills`**: This command installs Skills documentation files to `~/.skills/playwright-cli/` for coding agents to understand and use playwright-cli commands efficiently.\n\n2. **`claude mcp add playwright npx @playwright/mcp@latest`**: This command registers the official Microsoft Playwright MCP server with Claude Code, enabling browser automation tools.\n\n**Important Clarification**: The `--tool claude` flag is **not a valid flag** for either command. The commands mentioned in the issue work independently.\n\n---\n\n## Two Approaches: MCP vs CLI + Skills\n\n### Approach 1: Playwright MCP Server (Recommended for Most Users)\n\n**Installation**:\n\n```bash\nclaude mcp add playwright npx @playwright/mcp@latest\n```\n\n**How it works**:\n\n- Registers the official Microsoft Playwright MCP server with Claude Code\n- Provides 25+ browser automation tools directly accessible to Claude\n- Uses the Model Context Protocol standard developed by Anthropic\n\n**Key Features**:\n\n- Real-time browser control through accessibility snapshots\n- Visible browser window for authentication and debugging\n- Session persistence with cookies and local storage\n- Extensive configuration options (headless mode, viewport, proxy, etc.)\n\n**Available Tools** (partial list):\n\n- `browser_navigate`, `browser_navigate_back`\n- `browser_click`, `browser_type`, `browser_drag`\n- `browser_take_screenshot`, `browser_snapshot`\n- `browser_fill_form`, `browser_select_option`\n- `browser_wait_for`, `browser_tabs`\n- `browser_evaluate`, `browser_run_code`\n\n### Approach 2: Playwright CLI + Skills\n\n**Installation**:\n\n```bash\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n```\n\n**How it works**:\n\n- Installs Skills documentation to `~/.skills/playwright-cli/`\n- Claude Code reads these skill files for command understanding\n- CLI commands are invoked directly without an MCP server\n\n**Key Features**:\n\n- More token-efficient (avoids loading large tool schemas)\n- Works offline with static documentation\n- 40+ CLI commands across browser control, interaction, storage, network\n- Session management for parallel workflows\n\n---\n\n## Comparative Analysis\n\n### Feature Comparison\n\n| Feature | MCP Approach | CLI + Skills Approach |\n| --------------------- | -------------------------- | ----------------------------- |\n| **Setup Complexity** | Low (single command) | Medium (two commands) |\n| **Token Efficiency** | Lower (loads tool schemas) | Higher (33% savings reported) |\n| **Real-time Control** | Yes | Yes |\n| **Offline Support** | No | Yes (Skills are static) |\n| **Tool Discovery** | Automatic | Via `--help` or Skills docs |\n| **Maintenance** | Automatic with @latest | Manual CLI updates |\n| **Authentication** | Easy (visible browser) | Same capability |\n| **CI/CD Integration** | Good | Better |\n\n### Performance Metrics\n\nAccording to benchmarks and research:\n\n- **MCP**: Provides \"70% memory reduction\" through accessibility trees vs screenshots\n- **CLI + Skills**: Offers \"33% token savings\" in developer tasks due to avoided schema loading\n\n### Use Case Recommendations\n\n**Choose MCP when**:\n\n- You want the simplest setup\n- You need real-time browser interaction\n- You're doing exploratory testing or debugging\n- Authentication through visible browser is valuable\n- You prefer automatic tool discovery\n\n**Choose CLI + Skills when**:\n\n- Token efficiency is critical (large codebases)\n- You need offline capability\n- CI/CD pipeline integration is important\n- You want explicit control over commands\n- High-throughput automation is required\n\n---\n\n## Best Practices\n\n### For MCP Approach\n\n1. **Installation**:\n\n ```bash\n # Global (affects all directories)\n claude mcp add -s user playwright npx '@playwright/mcp@latest'\n\n # Project-specific\n claude mcp add playwright npx '@playwright/mcp@latest'\n ```\n\n2. **First Usage**: Explicitly mention \"playwright mcp\" in your first request:\n\n > \"Use playwright mcp to open a browser to example.com\"\n\n3. **Configuration Options**:\n\n ```bash\n # Headless mode for CI\n claude mcp add playwright npx @playwright/mcp@latest -- --headless\n\n # Specific browser\n claude mcp add playwright npx @playwright/mcp@latest -- --browser firefox\n\n # Custom viewport\n claude mcp add playwright npx @playwright/mcp@latest -- --viewport-size 1920x1080\n ```\n\n4. **Pre-install browsers** (recommended):\n\n ```bash\n npx playwright install\n npx playwright install-deps # Linux\n ```\n\n5. **Authentication Strategy**: Let Claude show you the login page, authenticate manually, then continue automation.\n\n### For CLI + Skills Approach\n\n1. **Installation**:\n\n ```bash\n npm install -g @playwright/cli@latest\n playwright-cli install --skills\n ```\n\n2. **Skills Location**: `~/.skills/playwright-cli/`\n - `SKILL.md`: Primary documentation\n - `references/*.md`: Detailed guides for specific tasks\n\n3. **Session Management**: Use `-s=name` flags for parallel isolated sessions.\n\n### Security Best Practices (Both Approaches)\n\n1. **Permission Awareness**: MCP servers execute with user permissions\n2. **Isolated Environments**: Use dedicated test environments\n3. **Audit Commands**: Review AI-generated automation before production use\n4. **Version Pinning**: Consider using specific versions instead of @latest in production\n\n---\n\n## Alternative Solutions & Libraries\n\n### 1. ExecuteAutomation's MCP-Playwright\n\n**Repository**: https://github.com/executeautomation/mcp-playwright\n\n**Installation**:\n\n```bash\nnpx @smithery/cli install @executeautomation/playwright-mcp-server --client claude\n```\n\n**Features**: Extended MCP implementation with additional automation capabilities.\n\n### 2. lackeyjb/playwright-skill\n\n**Repository**: https://github.com/lackeyjb/playwright-skill\n\n**Installation**:\n\n```bash\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\n**Features**: Model-invoked skill where Claude autonomously writes and executes custom Playwright code.\n\n### 3. Hybrid Approach\n\nFor production environments, consider combining both:\n\n```bash\n# MCP for real-time interactive debugging\nclaude mcp add playwright npx @playwright/mcp@latest\n\n# Skills for efficient scripted automation\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n```\n\n---\n\n## Configuration Files\n\n### Claude MCP Configuration (~/.claude.json)\n\n```json\n{\n \"mcpServers\": {\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\"]\n }\n }\n}\n```\n\n### With Options\n\n```json\n{\n \"mcpServers\": {\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\", \"--headless\", \"--browser\", \"chromium\", \"--viewport-size\", \"1280x720\"]\n }\n }\n}\n```\n\n### Environment Variables\n\nThe MCP server also supports environment variables:\n\n- `PLAYWRIGHT_MCP_BROWSER`: Browser type\n- `PLAYWRIGHT_MCP_HEADLESS`: Enable headless mode\n- `PLAYWRIGHT_MCP_ALLOWED_HOSTS`: Restrict accessible hosts\n\n---\n\n## Troubleshooting\n\n### Common Issues\n\n| Issue | Solution |\n| ------------------------------- | ---------------------------------------------- |\n| Claude uses Bash instead of MCP | Explicitly mention \"playwright mcp\" in request |\n| Browser not found | Run `npx playwright install` |\n| Permission errors | Pre-install browsers before running MCP |\n| Version conflicts | Use specific version instead of @latest |\n| Configuration not applied | Restart Claude Code after changes |\n\n### WSL/Linux Setup\n\n```bash\nsudo apt-get update\nsudo apt-get install -y chromium-browser\nexport CHROME_BIN=/usr/bin/chromium-browser\n```\n\n---\n\n## Conclusion\n\n### Recommended Default Setup\n\nFor most Claude Code CLI users, we recommend:\n\n```bash\n# Primary: MCP approach (simplest, most integrated)\nclaude mcp add playwright npx @playwright/mcp@latest\n\n# Pre-install browsers\nnpx playwright install\n```\n\n### For High-Performance/Production Environments\n\n```bash\n# CLI + Skills for token efficiency\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n\n# Plus MCP for interactive debugging\nclaude mcp add playwright npx @playwright/mcp@latest\n```\n\n### Key Takeaways\n\n1. **No `--tool claude` flag exists** - the commands in the issue work independently\n2. **MCP is simpler** for most users and recommended by official documentation\n3. **CLI + Skills is more token-efficient** for high-throughput scenarios\n4. **Both approaches are valid** and can be used together\n5. **Pre-installing browsers** is a best practice for both approaches\n\n---\n\n## References\n\n### Official Documentation\n\n- [Microsoft Playwright MCP Repository](https://github.com/microsoft/playwright-mcp)\n- [Microsoft Playwright CLI Repository](https://github.com/microsoft/playwright-cli)\n- [Anthropic Model Context Protocol](https://www.anthropic.com/engineering/code-execution-with-mcp)\n\n### Tutorials & Guides\n\n- [Simon Willison: Using Playwright MCP with Claude Code](https://til.simonwillison.net/claude-code/playwright-mcp-claude-code)\n- [Supatest: Playwright MCP Setup Guide](https://supatest.ai/blog/playwright-mcp-setup-guide)\n- [Testomat: Playwright MCP Claude Code](https://testomat.io/blog/playwright-mcp-claude-code/)\n\n### Comparative Analysis\n\n- [CosmicJS: MCP vs Skills Guide](https://www.cosmicjs.com/blog/mcp-vs-skills-ai-coding-assistant-integrations-guide)\n- [IntuitionLabs: Claude Skills vs MCP](https://intuitionlabs.ai/articles/claude-skills-vs-mcp)\n- [CLI-Agent vs MCP Practical Comparison](https://medium.com/@girmish/cli-agent-vs-mcp-a-practical-comparison-for-students-startups-and-developers-2026-b9fe30a96559)\n\n### Alternative Implementations\n\n- [ExecuteAutomation MCP-Playwright](https://github.com/executeautomation/mcp-playwright)\n- [lackeyjb/playwright-skill](https://github.com/lackeyjb/playwright-skill)\n",

Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.\nlicense: Complete terms in LICENSE.txt\n---\n\nThis skill guides creation of distinctive, production-grade frontend interfaces that avoid generic \"AI slop\" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.\n\nThe user provides frontend requirements: a component, page, application, or interface to build. They may include context about the purpose, audience, or technical constraints.\n\n## Design Thinking\n\nBefore coding, understand the context and commit to a BOLD aesthetic direction:\n- **Purpose**: What problem does this interface solve? Who uses it?\n- **Tone**: Pick an extreme: brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian, etc. There are so many flavors to choose from. Use these for inspiration but design one that is true to the aesthetic direction.\n- **Constraints**: Technical requirements (framework, performance, accessibility).\n- **Differentiation**: What makes this UNFORGETTABLE? What's the one thing someone will remember?\n\n**CRITICAL**: Choose a clear conceptual direction and execute it with precision. Bold maximalism and refined minimalism both work - the key is intentionality, not intensity.\n\nThen implement working code (HTML/CSS/JS, React, Vue, etc.) that is:\n- Production-grade and functional\n- Visually striking and memorable\n- Cohesive with a clear aesthetic point-of-view\n- Meticulously refined in every detail\n\n## Frontend Aesthetics Guidelines\n\nFocus on:\n- **Typography**: Choose fonts that are beautiful, unique, and interesting. Avoid generic fonts like Arial and Inter; opt instead for distinctive choices that elevate the frontend's aesthetics; unexpected, characterful font choices. Pair a distinctive display font with a refined body font.\n- **Color & Theme**: Commit to a cohesive aesthetic. Use CSS variables for consistency. Dominant colors with sharp accents outperform timid, evenly-distributed palettes.\n- **Motion**: Use animations for effects and micro-interactions. Prioritize CSS-only solutions for HTML. Use Motion library for React when available. Focus on high-impact moments: one well-orchestrated page load with staggered reveals (animation-delay) creates more delight than scattered micro-interactions. Use scroll-triggering and hover states that surprise.\n- **Spatial Composition**: Unexpected layouts. Asymmetry. Overlap. Diagonal flow. Grid-breaking elements. Generous negative space OR controlled density.\n- **Backgrounds & Visual Details**: Create atmosphere and depth rather than defaulting to solid colors. Add contextual effects and textures that match the overall aesthetic. Apply creative forms like gradient meshes, noise textures, geometric patterns, layered transparencies, dramatic shadows, decorative borders, custom cursors, and grain overlays.\n\nNEVER use generic AI-generated aesthetics like overused font families (Inter, Roboto, Arial, system fonts), cliched color schemes (particularly purple gradients on white backgrounds), predictable layouts and component patterns, and cookie-cutter design that lacks context-specific character.\n\nInterpret creatively and make unexpected choices that feel genuinely designed for the context. No design should be the same. Vary between light and dark themes, different fonts, different aesthetics. NEVER converge on common choices (Space Grotesk, for example) across generations.\n\n**IMPORTANT**: Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code with extensive animations and effects. Minimalist or refined designs need restraint, precision, and careful attention to spacing, typography, and subtle details. Elegance comes from executing the vision well.\n\nRemember: Claude is capable of extraordinary creative work. Don't hold back, show what can truly be created when thinking outside the box and committing fully to a distinctive vision.",

Bold maximalism and refined minimalism both work - the key is intentionality, not intensity.\n\nThen implement working code (HTML/CSS/JS, React, Vue, etc.) that is:\n- Production-grade and functional\n- Visually striking and memorable\n- Cohesive with a clear aesthetic point-of-view\n- Meticulously refined in every detail\n\n## Frontend Aesthetics Guidelines\n\nFocus on:\n- **Typography**: Choose fonts that are beautiful, unique, and interesting. Avoid generic fonts like Arial and Inter; opt instead for distinctive choices that elevate the frontend's aesthetics; unexpected, characterful font choices. Pair a distinctive display font with a refined body font.\n- **Color & Theme**: Commit to a cohesive aesthetic. Use CSS variables for consistency. Dominant colors with sharp accents outperform timid, evenly-distributed palettes.\n- **Motion**: Use animations for effects and micro-interactions. Prioritize CSS-only solutions for HTML. Use Motion library for React when available. Focus on high-impact moments: one well-orchestrated page load with staggered reveals (animation-delay) creates more delight than scattered micro-interactions. Use scroll-triggering and hover states that surprise.\n- **Spatial Composition**: Unexpected layouts. Asymmetry. Overlap. Diagonal flow. Grid-breaking elements. Generous negative space OR controlled density.\n- **Backgrounds & Visual Details**: Create atmosphere and depth rather than defaulting to solid colors. Add contextual effects and textures that match the overall aesthetic. Apply creative forms like gradient meshes, noise textures, geometric patterns, layered transparencies, dramatic shadows, decorative borders, custom cursors, and grain overlays.\n\nNEVER use generic AI-generated aesthetics like overused font families (Inter, Roboto, Arial, system fonts), cliched color schemes (particularly purple gradients on white backgrounds), predictable layouts and component patterns, and cookie-cutter design that lacks context-specific character.\n\nInterpret creatively and make unexpected choices that feel genuinely designed for the context. No design should be the same. Vary between light and dark themes, different fonts, different aesthetics. NEVER converge on common choices (Space Grotesk, for example) across generations.\n\n**IMPORTANT**: Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code with extensive animations and effects. Minimalist or refined designs need restraint, precision, and careful attention to spacing, typography, and subtle details. Elegance comes from executing the vision well.\n\nRemember: Claude is capable of extraordinary creative work. Don't hold back, show what can truly be created when thinking outside the box and committing fully to a distinctive vision.",

"new_string": "### Key Takeaways\n\n1. **No `--tool claude` flag exists** - the commands in the issue work independently\n2. **MCP is simpler** for most users and recommended by official documentation\n3. **CLI + Skills is more token-efficient** for high-throughput scenarios\n4. **Both approaches are valid** and can be used together\n5. **Pre-installing browsers** is a best practice for both approaches\n\n---\n\n## Update (2026-03-14): Claude Code Plugins Ecosystem\n\n### Background\n\nClaude Code introduced a **plugin system** (v1.0.33+) that packages skills, agents, hooks, and MCP servers into installable, shareable bundles distributed via Git-based marketplaces. This section addresses the follow-up questions about how Claude Code plugins relate to Playwright MCP.\n\n### Three Approaches to Playwright in Claude Code (2026)\n\nThere are now **three** distinct approaches for using Playwright with Claude Code:\n\n| # | Approach | Installation | How It Works |\n|---|----------|-------------|-------------|\n| 1 | **Playwright MCP** (manual) | `claude mcp add playwright npx @playwright/mcp@latest` | Registers Microsoft's MCP server directly in `~/.claude.json` |\n| 2 | **Playwright Plugin** (official marketplace) | `/plugin install playwright@claude-plugins-official` | Installs the same MCP server, but packaged as a plugin |\n| 3 | **Playwright Skill** (community) | `/plugin marketplace add lackeyjb/playwright-skill` then `/plugin install playwright-skill@playwright-skill` | Claude writes and executes Playwright code directly (no MCP server) |\n\n### Approach 2: Official Playwright Plugin (Details)\n\nThe **official Playwright plugin** in `claude-plugins-official` (102,750+ installs, by Microsoft) is a thin wrapper around the same `@playwright/mcp@latest` MCP server. Its `plugin.json`:\n\n```json\n{\n \"name\": \"playwright\",\n \"description\": \"Browser automation and end-to-end testing MCP server by Microsoft. Enables Claude to interact with web pages, take screenshots, fill forms, click elements, and perform automated browser testing workflows.\",\n \"author\": { \"name\": \"Microsoft\" }\n}\n```\n\nIts `.mcp.json`:\n\n```json\n{\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\"]\n }\n}\n```\n\n**Key insight**: Approaches 1 and 2 are functionally identical — the plugin simply provides a managed installation experience via the plugin system. The underlying MCP server is the same.\n\n### Approach 3: Playwright Skill Plugin (Details)\n\nThe **community Playwright Skill** by [lackeyjb](https://github.com/lackeyjb/playwright-skill) takes a fundamentally different approach:\n\n- **Instead of MCP tools**: Claude writes custom Playwright code and executes it\n- **Returns**: Screenshots and console output (not accessibility tree snapshots)\n- **Token usage**: ~314 lines of skill instructions vs. a persistent MCP server\n- **Best for**: \"Scriptable manual testing\" during local development — quick validation like \"does my new feature work?\"\n- **Not designed for**: Comprehensive CI/CD test suites\n\nInstallation:\n\n```bash\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\n### Frontend-Design Plugin: NOT Related to Playwright\n\nThe `frontend-design` plugin (by Anthropic, 324,000+ installs) is a **design aesthetics skill** that helps Claude create visually distinctive UI code. It has **no Playwright dependency** and **no browser automation capability**. It auto-activates when Claude detects frontend development tasks and guides bold design choices (typography, color, animation, layout).\n\n### Correct Plugin Install Commands\n\nThe commands mentioned in the PR comment are **not correct**. Here are the correct commands:\n\n| Incorrect Command | Correct Alternative |\n|---|---|\n| `claude plugin install @anthropic/frontend-design` | `/plugin install frontend-design@claude-plugins-official` |\n| `/plugin install frontend-design@anthropics-claude-code` | `/plugin install frontend-design@claude-plugins-official` |\n\n**Correct syntax**: `/plugin install {plugin-name}@{marketplace-name}`\n\nThe official Anthropic marketplace is `claude-plugins-official` (pre-configured, no need to add it). The demo marketplace at `anthropics/claude-code` must be added first with `/plugin marketplace add anthropics/claude-code`.\n\n### Can Playwright MCP and Playwright Plugin Coexist?\n\n**Yes, but they shouldn't be used simultaneously.** Since the official Playwright plugin wraps the same MCP server, running both would create a duplicate `playwright` MCP registration. Choose one:\n\n| Scenario | Recommended Approach |\n|---|---|\n| Simple setup, want managed updates | `/plugin install playwright@claude-plugins-official` |\n| Custom MCP arguments (headless, viewport, browser) | `claude mcp add playwright npx @playwright/mcp@latest -- --headless` |\n| Token-efficient scriptable testing | `/plugin install playwright-skill@playwright-skill` (community) |\n| Maximum flexibility | MCP (manual) + Playwright Skill plugin (these are complementary) |\n\n**The MCP-based approaches (1 and 2) and the Skill approach (3) CAN coexist** because they use different mechanisms:\n- MCP: Provides browser automation tools that Claude calls\n- Skill: Provides instructions that Claude uses to write and execute Playwright scripts directly\n\n### Plugin Management Commands\n\n```bash\n# List installed plugins\n/plugin list\n\n# Browse available plugins interactively\n/plugin\n\n# Install from official marketplace (pre-configured)\n/plugin install playwright@claude-plugins-official\n/plugin install frontend-design@claude-plugins-official\n\n# Add a third-party marketplace\n/plugin marketplace add lackeyjb/playwright-skill\n\n# Install from third-party marketplace\n/plugin install playwright-skill@playwright-skill\n\n# Disable/enable/remove plugins\n/plugin disable playwright@claude-plugins-official\n/plugin enable playwright@claude-plugins-official\n/plugin uninstall playwright@claude-plugins-official\n\n# Reload after changes\n/reload-plugins\n```\n\n### Updated Recommendations (2026-03)\n\nFor most users, the simplest path is now:\n\n```bash\n# Install official Playwright plugin (wraps MCP server)\n/plugin install playwright@claude-plugins-official\n\n# Pre-install browsers\nnpx playwright install\n```\n\nFor advanced users wanting both MCP tools AND efficient scripted testing:\n\n```bash\n# Option A: Official plugin for MCP tools\n/plugin install playwright@claude-plugins-official\n\n# Option B: Community skill for script-based testing\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\nFor frontend design quality (unrelated to Playwright):\n\n```bash\n/plugin install frontend-design@claude-plugins-official\n```\n\n---\n\n## References"

This section addresses the follow-up questions about how Claude Code plugins relate to Playwright MCP.\n\n### Three Approaches to Playwright in Claude Code (2026)\n\nThere are now **three** distinct approaches for using Playwright with Claude Code:\n\n| # | Approach | Installation | How It Works |\n|---|----------|-------------|-------------|\n| 1 | **Playwright MCP** (manual) | `claude mcp add playwright npx @playwright/mcp@latest` | Registers Microsoft's MCP server directly in `~/.claude.json` |\n| 2 | **Playwright Plugin** (official marketplace) | `/plugin install playwright@claude-plugins-official` | Installs the same MCP server, but packaged as a plugin |\n| 3 | **Playwright Skill** (community) | `/plugin marketplace add lackeyjb/playwright-skill` then `/plugin install playwright-skill@playwright-skill` | Claude writes and executes Playwright code directly (no MCP server) |\n\n### Approach 2: Official Playwright Plugin (Details)\n\nThe **official Playwright plugin** in `claude-plugins-official` (102,750+ installs, by Microsoft) is a thin wrapper around the same `@playwright/mcp@latest` MCP server. Its `plugin.json`:\n\n```json\n{\n \"name\": \"playwright\",\n \"description\": \"Browser automation and end-to-end testing MCP server by Microsoft. Enables Claude to interact with web pages, take screenshots, fill forms, click elements, and perform automated browser testing workflows.\",\n \"author\": { \"name\": \"Microsoft\" }\n}\n```\n\nIts `.mcp.json`:\n\n```json\n{\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\"]\n }\n}\n```\n\n**Key insight**: Approaches 1 and 2 are functionally identical — the plugin simply provides a managed installation experience via the plugin system. The underlying MCP server is the same.\n\n### Approach 3: Playwright Skill Plugin (Details)\n\nThe **community Playwright Skill** by [lackeyjb](https://github.com/lackeyjb/playwright-skill) takes a fundamentally different approach:\n\n- **Instead of MCP tools**: Claude writes custom Playwright code and executes it\n- **Returns**: Screenshots and console output (not accessibility tree snapshots)\n- **Token usage**: ~314 lines of skill instructions vs. a persistent MCP server\n- **Best for**: \"Scriptable manual testing\" during local development — quick validation like \"does my new feature work?\"\n- **Not designed for**: Comprehensive CI/CD test suites\n\nInstallation:\n\n```bash\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\n### Frontend-Design Plugin: NOT Related to Playwright\n\nThe `frontend-design` plugin (by Anthropic, 324,000+ installs) is a **design aesthetics skill** that helps Claude create visually distinctive UI code. It has **no Playwright dependency** and **no browser automation capability**. It auto-activates when Claude detects frontend development tasks and guides bold design choices (typography, color, animation, layout).\n\n### Correct Plugin Install Commands\n\nThe commands mentioned in the PR comment are **not correct**. Here are the correct commands:\n\n| Incorrect Command | Correct Alternative |\n|---|---|\n| `claude plugin install @anthropic/frontend-design` | `/plugin install frontend-design@claude-plugins-official` |\n| `/plugin install frontend-design@anthropics-claude-code` | `/plugin install frontend-design@claude-plugins-official` |\n\n**Correct syntax**: `/plugin install {plugin-name}@{marketplace-name}`\n\nThe official Anthropic marketplace is `claude-plugins-official` (pre-configured, no need to add it). The demo marketplace at `anthropics/claude-code` must be added first with `/plugin marketplace add anthropics/claude-code`.\n\n### Can Playwright MCP and Playwright Plugin Coexist?\n\n**Yes, but they shouldn't be used simultaneously.** Since the official Playwright plugin wraps the same MCP server, running both would create a duplicate `playwright` MCP registration. Choose one:\n\n| Scenario | Recommended Approach |\n|---|---|\n| Simple setup, want managed updates | `/plugin install playwright@claude-plugins-official` |\n| Custom MCP arguments (headless, viewport, browser) | `claude mcp add playwright npx @playwright/mcp@latest -- --headless` |\n| Token-efficient scriptable testing | `/plugin install playwright-skill@playwright-skill` (community) |\n| Maximum flexibility | MCP (manual) + Playwright Skill plugin (these are complementary) |\n\n**The MCP-based approaches (1 and 2) and the Skill approach (3) CAN coexist** because they use different mechanisms:\n- MCP: Provides browser automation tools that Claude calls\n- Skill: Provides instructions that Claude uses to write and execute Playwright scripts directly\n\n### Plugin Management Commands\n\n```bash\n# List installed plugins\n/plugin list\n\n# Browse available plugins interactively\n/plugin\n\n# Install from official marketplace (pre-configured)\n/plugin install playwright@claude-plugins-official\n/plugin install frontend-design@claude-plugins-official\n\n# Add a third-party marketplace\n/plugin marketplace add lackeyjb/playwright-skill\n\n# Install from third-party marketplace\n/plugin install playwright-skill@playwright-skill\n\n# Disable/enable/remove plugins\n/plugin disable playwright@claude-plugins-official\n/plugin enable playwright@claude-plugins-official\n/plugin uninstall playwright@claude-plugins-official\n\n# Reload after changes\n/reload-plugins\n```\n\n### Updated Recommendations (2026-03)\n\nFor most users, the simplest path is now:\n\n```bash\n# Install official Playwright plugin (wraps MCP server)\n/plugin install playwright@claude-plugins-official\n\n# Pre-install browsers\nnpx playwright install\n```\n\nFor advanced users wanting both MCP tools AND efficient scripted testing:\n\n```bash\n# Option A: Official plugin for MCP tools\n/plugin install playwright@claude-plugins-official\n\n# Option B: Community skill for script-based testing\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\nFor frontend design quality (unrelated to Playwright):\n\n```bash\n/plugin install frontend-design@claude-plugins-official\n```\n\n---\n\n## References",
"originalFile": "# Case Study: Playwright MCP Best Practices for Claude Code CLI\n\n## Issue Reference\n\n- **Issue**: https://github.com/link-assistant/hive-mind/issues/1284\n- **Date**: 2026-02-13\n- **Tags**: documentation, enhancement, question\n- **Author**: konard\n\n## Executive Summary\n\nThis case study investigates the best practices for using Playwright with Claude Code CLI, comparing two primary approaches:\n\n1. **MCP (Model Context Protocol)**: `claude mcp add playwright npx @playwright/mcp@latest`\n2. **CLI + Skills**: `playwright-cli install --skills`\n\nOur research concludes that **both approaches have valid use cases**, and the optimal choice depends on the specific workflow requirements. For most Claude Code CLI users, the **MCP approach is currently the recommended default**, while the CLI + Skills approach offers advantages for high-throughput, token-efficient scenarios.\n\n---\n\n## The Question\n\nThe issue asks:\n\n> Do we actually use all these with `--tool claude`? Is there any better practices in the internet?\n>\n> ```\n> playwright-cli install --skills\n> claude mcp add playwright npx @playwright/mcp@latest\n> ```\n\n### Analysis of the Commands\n\n1. **`playwright-cli install --skills`**: This command installs Skills documentation files to `~/.skills/playwright-cli/` for coding agents to understand and use playwright-cli commands efficiently.\n\n2. **`claude mcp add playwright npx @playwright/mcp@latest`**: This command registers the official Microsoft Playwright MCP server with Claude Code, enabling browser automation tools.\n\n**Important Clarification**: The `--tool claude` flag is **not a valid flag** for either command. The commands mentioned in the issue work independently.\n\n---\n\n## Two Approaches: MCP vs CLI + Skills\n\n### Approach 1: Playwright MCP Server (Recommended for Most Users)\n\n**Installation**:\n\n```bash\nclaude mcp add playwright npx @playwright/mcp@latest\n```\n\n**How it works**:\n\n- Registers the official Microsoft Playwright MCP server with Claude Code\n- Provides 25+ browser automation tools directly accessible to Claude\n- Uses the Model Context Protocol standard developed by Anthropic\n\n**Key Features**:\n\n- Real-time browser control through accessibility snapshots\n- Visible browser window for authentication and debugging\n- Session persistence with cookies and local storage\n- Extensive configuration options (headless mode, viewport, proxy, etc.)\n\n**Available Tools** (partial list):\n\n- `browser_navigate`, `browser_navigate_back`\n- `browser_click`, `browser_type`, `browser_drag`\n- `browser_take_screenshot`, `browser_snapshot`\n- `browser_fill_form`, `browser_select_option`\n- `browser_wait_for`, `browser_tabs`\n- `browser_evaluate`, `browser_run_code`\n\n### Approach 2: Playwright CLI + Skills\n\n**Installation**:\n\n```bash\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n```\n\n**How it works**:\n\n- Installs Skills documentation to `~/.skills/playwright-cli/`\n- Claude Code reads these skill files for command understanding\n- CLI commands are invoked directly without an MCP server\n\n**Key Features**:\n\n- More token-efficient (avoids loading large tool schemas)\n- Works offline with static documentation\n- 40+ CLI commands across browser control, interaction, storage, network\n- Session management for parallel workflows\n\n---\n\n## Comparative Analysis\n\n### Feature Comparison\n\n| Feature | MCP Approach | CLI + Skills Approach |\n| --------------------- | -------------------------- | ----------------------------- |\n| **Setup Complexity** | Low (single command) | Medium (two commands) |\n| **Token Efficiency** | Lower (loads tool schemas) | Higher (33% savings reported) |\n| **Real-time Control** | Yes | Yes |\n| **Offline Support** | No | Yes (Skills are static) |\n| **Tool Discovery** | Automatic | Via `--help` or Skills docs |\n| **Maintenance** | Automatic with @latest | Manual CLI updates |\n| **Authentication** | Easy (visible browser) | Same capability |\n| **CI/CD Integration** | Good | Better |\n\n### Performance Metrics\n\nAccording to benchmarks and research:\n\n- **MCP**: Provides \"70% memory reduction\" through accessibility trees vs screenshots\n- **CLI + Skills**: Offers \"33% token savings\" in developer tasks due to avoided schema loading\n\n### Use Case Recommendations\n\n**Choose MCP when**:\n\n- You want the simplest setup\n- You need real-time browser interaction\n- You're doing exploratory testing or debugging\n- Authentication through visible browser is valuable\n- You prefer automatic tool discovery\n\n**Choose CLI + Skills when**:\n\n- Token efficiency is critical (large codebases)\n- You need offline capability\n- CI/CD pipeline integration is important\n- You want explicit control over commands\n- High-throughput automation is required\n\n---\n\n## Best Practices\n\n### For MCP Approach\n\n1. **Installation**:\n\n ```bash\n # Global (affects all directories)\n claude mcp add -s user playwright npx '@playwright/mcp@latest'\n\n # Project-specific\n claude mcp add playwright npx '@playwright/mcp@latest'\n ```\n\n2. **First Usage**: Explicitly mention \"playwright mcp\" in your first request:\n\n > \"Use playwright mcp to open a browser to example.com\"\n\n3. **Configuration Options**:\n\n ```bash\n # Headless mode for CI\n claude mcp add playwright npx @playwright/mcp@latest -- --headless\n\n # Specific browser\n claude mcp add playwright npx @playwright/mcp@latest -- --browser firefox\n\n # Custom viewport\n claude mcp add playwright npx @playwright/mcp@latest -- --viewport-size 1920x1080\n ```\n\n4. **Pre-install browsers** (recommended):\n\n ```bash\n npx playwright install\n npx playwright install-deps # Linux\n ```\n\n5. **Authentication Strategy**: Let Claude show you the login page, authenticate manually, then continue automation.\n\n### For CLI + Skills Approach\n\n1. **Installation**:\n\n ```bash\n npm install -g @playwright/cli@latest\n playwright-cli install --skills\n ```\n\n2. **Skills Location**: `~/.skills/playwright-cli/`\n - `SKILL.md`: Primary documentation\n - `references/*.md`: Detailed guides for specific tasks\n\n3. **Session Management**: Use `-s=name` flags for parallel isolated sessions.\n\n### Security Best Practices (Both Approaches)\n\n1. **Permission Awareness**: MCP servers execute with user permissions\n2. **Isolated Environments**: Use dedicated test environments\n3. **Audit Commands**: Review AI-generated automation before production use\n4. **Version Pinning**: Consider using specific versions instead of @latest in production\n\n---\n\n## Alternative Solutions & Libraries\n\n### 1. ExecuteAutomation's MCP-Playwright\n\n**Repository**: https://github.com/executeautomation/mcp-playwright\n\n**Installation**:\n\n```bash\nnpx @smithery/cli install @executeautomation/playwright-mcp-server --client claude\n```\n\n**Features**: Extended MCP implementation with additional automation capabilities.\n\n### 2. lackeyjb/playwright-skill\n\n**Repository**: https://github.com/lackeyjb/playwright-skill\n\n**Installation**:\n\n```bash\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\n**Features**: Model-invoked skill where Claude autonomously writes and executes custom Playwright code.\n\n### 3. Hybrid Approach\n\nFor production environments, consider combining both:\n\n```bash\n# MCP for real-time interactive debugging\nclaude mcp add playwright npx @playwright/mcp@latest\n\n# Skills for efficient scripted automation\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n```\n\n---\n\n## Configuration Files\n\n### Claude MCP Configuration (~/.claude.json)\n\n```json\n{\n \"mcpServers\": {\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\"]\n }\n }\n}\n```\n\n### With Options\n\n```json\n{\n \"mcpServers\": {\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\", \"--headless\", \"--browser\", \"chromium\", \"--viewport-size\", \"1280x720\"]\n }\n }\n}\n```\n\n### Environment Variables\n\nThe MCP server also supports environment variables:\n\n- `PLAYWRIGHT_MCP_BROWSER`: Browser type\n- `PLAYWRIGHT_MCP_HEADLESS`: Enable headless mode\n- `PLAYWRIGHT_MCP_ALLOWED_HOSTS`: Restrict accessible hosts\n\n---\n\n## Troubleshooting\n\n### Common Issues\n\n| Issue | Solution |\n| ------------------------------- | ---------------------------------------------- |\n| Claude uses Bash instead of MCP | Explicitly mention \"playwright mcp\" in request |\n| Browser not found | Run `npx playwright install` |\n| Permission errors | Pre-install browsers before running MCP |\n| Version conflicts | Use specific version instead of @latest |\n| Configuration not applied | Restart Claude Code after changes |\n\n### WSL/Linux Setup\n\n```bash\nsudo apt-get update\nsudo apt-get install -y chromium-browser\nexport CHROME_BIN=/usr/bin/chromium-browser\n```\n\n---\n\n## Conclusion\n\n### Recommended Default Setup\n\nFor most Claude Code CLI users, we recommend:\n\n```bash\n# Primary: MCP approach (simplest, most integrated)\nclaude mcp add playwright npx @playwright/mcp@latest\n\n# Pre-install browsers\nnpx playwright install\n```\n\n### For High-Performance/Production Environments\n\n```bash\n# CLI + Skills for token efficiency\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n\n# Plus MCP for interactive debugging\nclaude mcp add playwright npx @playwright/mcp@latest\n```\n\n### Key Takeaways\n\n1. **No `--tool claude` flag exists** - the commands in the issue work independently\n2. **MCP is simpler** for most users and recommended by official documentation\n3. **CLI + Skills is more token-efficient** for high-throughput scenarios\n4. **Both approaches are valid** and can be used together\n5. **Pre-installing browsers** is a best practice for both approaches\n\n---\n\n## References\n\n### Official Documentation\n\n- [Microsoft Playwright MCP Repository](https://github.com/microsoft/playwright-mcp)\n- [Microsoft Playwright CLI Repository](https://github.com/microsoft/playwright-cli)\n- [Anthropic Model Context Protocol](https://www.anthropic.com/engineering/code-execution-with-mcp)\n\n### Tutorials & Guides\n\n- [Simon Willison: Using Playwright MCP with Claude Code](https://til.simonwillison.net/claude-code/playwright-mcp-claude-code)\n- [Supatest: Playwright MCP Setup Guide](https://supatest.ai/blog/playwright-mcp-setup-guide)\n- [Testomat: Playwright MCP Claude Code](https://testomat.io/blog/playwright-mcp-claude-code/)\n\n### Comparative Analysis\n\n- [CosmicJS: MCP vs Skills Guide](https://www.cosmicjs.com/blog/mcp-vs-skills-ai-coding-assistant-integrations-guide)\n- [IntuitionLabs: Claude Skills vs MCP](https://intuitionlabs.ai/articles/claude-skills-vs-mcp)\n- [CLI-Agent vs MCP Practical Comparison](https://medium.com/@girmish/cli-agent-vs-mcp-a-practical-comparison-for-students-startups-and-developers-2026-b9fe30a96559)\n\n### Alternative Implementations\n\n- [ExecuteAutomation MCP-Playwright](https://github.com/executeautomation/mcp-playwright)\n- [lackeyjb/playwright-skill](https://github.com/lackeyjb/playwright-skill)\n",

"originalFile": "# Case Study: Playwright MCP Best Practices for Claude Code CLI\n\n## Issue Reference\n\n- **Issue**: https://github.com/link-assistant/hive-mind/issues/1284\n- **Date**: 2026-02-13\n- **Tags**: documentation, enhancement, question\n- **Author**: konard\n\n## Executive Summary\n\nThis case study investigates the best practices for using Playwright with Claude Code CLI, comparing two primary approaches:\n\n1. **MCP (Model Context Protocol)**: `claude mcp add playwright npx @playwright/mcp@latest`\n2. **CLI + Skills**: `playwright-cli install --skills`\n\nOur research concludes that **both approaches have valid use cases**, and the optimal choice depends on the specific workflow requirements. For most Claude Code CLI users, the **MCP approach is currently the recommended default**, while the CLI + Skills approach offers advantages for high-throughput, token-efficient scenarios.\n\n---\n\n## The Question\n\nThe issue asks:\n\n> Do we actually use all these with `--tool claude`? Is there any better practices in the internet?\n>\n> ```\n> playwright-cli install --skills\n> claude mcp add playwright npx @playwright/mcp@latest\n> ```\n\n### Analysis of the Commands\n\n1. **`playwright-cli install --skills`**: This command installs Skills documentation files to `~/.skills/playwright-cli/` for coding agents to understand and use playwright-cli commands efficiently.\n\n2. **`claude mcp add playwright npx @playwright/mcp@latest`**: This command registers the official Microsoft Playwright MCP server with Claude Code, enabling browser automation tools.\n\n**Important Clarification**: The `--tool claude` flag is **not a valid flag** for either command. The commands mentioned in the issue work independently.\n\n---\n\n## Two Approaches: MCP vs CLI + Skills\n\n### Approach 1: Playwright MCP Server (Recommended for Most Users)\n\n**Installation**:\n\n```bash\nclaude mcp add playwright npx @playwright/mcp@latest\n```\n\n**How it works**:\n\n- Registers the official Microsoft Playwright MCP server with Claude Code\n- Provides 25+ browser automation tools directly accessible to Claude\n- Uses the Model Context Protocol standard developed by Anthropic\n\n**Key Features**:\n\n- Real-time browser control through accessibility snapshots\n- Visible browser window for authentication and debugging\n- Session persistence with cookies and local storage\n- Extensive configuration options (headless mode, viewport, proxy, etc.)\n\n**Available Tools** (partial list):\n\n- `browser_navigate`, `browser_navigate_back`\n- `browser_click`, `browser_type`, `browser_drag`\n- `browser_take_screenshot`, `browser_snapshot`\n- `browser_fill_form`, `browser_select_option`\n- `browser_wait_for`, `browser_tabs`\n- `browser_evaluate`, `browser_run_code`\n\n### Approach 2: Playwright CLI + Skills\n\n**Installation**:\n\n```bash\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n```\n\n**How it works**:\n\n- Installs Skills documentation to `~/.skills/playwright-cli/`\n- Claude Code reads these skill files for command understanding\n- CLI commands are invoked directly without an MCP server\n\n**Key Features**:\n\n- More token-efficient (avoids loading large tool schemas)\n- Works offline with static documentation\n- 40+ CLI commands across browser control, interaction, storage, network\n- Session management for parallel workflows\n\n---\n\n## Comparative Analysis\n\n### Feature Comparison\n\n| Feature | MCP Approach | CLI + Skills Approach |\n| --------------------- | -------------------------- | ----------------------------- |\n| **Setup Complexity** | Low (single command) | Medium (two commands) |\n| **Token Efficiency** | Lower (loads tool schemas) | Higher (33% savings reported) |\n| **Real-time Control** | Yes | Yes |\n| **Offline Support** | No | Yes (Skills are static) |\n| **Tool Discovery** | Automatic | Via `--help` or Skills docs |\n| **Maintenance** | Automatic with @latest | Manual CLI updates |\n| **Authentication** | Easy (visible browser) | Same capability |\n| **CI/CD Integration** | Good | Better |\n\n### Performance Metrics\n\nAccording to benchmarks and research:\n\n- **MCP**: Provides \"70% memory reduction\" through accessibility trees vs screenshots\n- **CLI + Skills**: Offers \"33% token savings\" in developer tasks due to avoided schema loading\n\n### Use Case Recommendations\n\n**Choose MCP when**:\n\n- You want the simplest setup\n- You need real-time browser interaction\n- You're doing exploratory testing or debugging\n- Authentication through visible browser is valuable\n- You prefer automatic tool discovery\n\n**Choose CLI + Skills when**:\n\n- Token efficiency is critical (large codebases)\n- You need offline capability\n- CI/CD pipeline integration is important\n- You want explicit control over commands\n- High-throughput automation is required\n\n---\n\n## Best Practices\n\n### For MCP Approach\n\n1. **Installation**:\n\n ```bash\n # Global (affects all directories)\n claude mcp add -s user playwright npx '@playwright/mcp@latest'\n\n # Project-specific\n claude mcp add playwright npx '@playwright/mcp@latest'\n ```\n\n2. **First Usage**: Explicitly mention \"playwright mcp\" in your first request:\n\n > \"Use playwright mcp to open a browser to example.com\"\n\n3. **Configuration Options**:\n\n ```bash\n # Headless mode for CI\n claude mcp add playwright npx @playwright/mcp@latest -- --headless\n\n # Specific browser\n claude mcp add playwright npx @playwright/mcp@latest -- --browser firefox\n\n # Custom viewport\n claude mcp add playwright npx @playwright/mcp@latest -- --viewport-size 1920x1080\n ```\n\n4. **Pre-install browsers** (recommended):\n\n ```bash\n npx playwright install\n npx playwright install-deps # Linux\n ```\n\n5. **Authentication Strategy**: Let Claude show you the login page, authenticate manually, then continue automation.\n\n### For CLI + Skills Approach\n\n1. **Installation**:\n\n ```bash\n npm install -g @playwright/cli@latest\n playwright-cli install --skills\n ```\n\n2. **Skills Location**: `~/.skills/playwright-cli/`\n - `SKILL.md`: Primary documentation\n - `references/*.md`: Detailed guides for specific tasks\n\n3. **Session Management**: Use `-s=name` flags for parallel isolated sessions.\n\n### Security Best Practices (Both Approaches)\n\n1. **Permission Awareness**: MCP servers execute with user permissions\n2. **Isolated Environments**: Use dedicated test environments\n3. **Audit Commands**: Review AI-generated automation before production use\n4. **Version Pinning**: Consider using specific versions instead of @latest in production\n\n---\n\n## Alternative Solutions & Libraries\n\n### 1. ExecuteAutomation's MCP-Playwright\n\n**Repository**: https://github.com/executeautomation/mcp-playwright\n\n**Installation**:\n\n```bash\nnpx @smithery/cli install @executeautomation/playwright-mcp-server --client claude\n```\n\n**Features**: Extended MCP implementation with additional automation capabilities.\n\n### 2. lackeyjb/playwright-skill\n\n**Repository**: https://github.com/lackeyjb/playwright-skill\n\n**Installation**:\n\n```bash\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\n**Features**: Model-invoked skill where Claude autonomously writes and executes custom Playwright code.\n\n### 3. Hybrid Approach\n\nFor production environments, consider combining both:\n\n```bash\n# MCP for real-time interactive debugging\nclaude mcp add playwright npx @playwright/mcp@latest\n\n# Skills for efficient scripted automation\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n```\n\n---\n\n## Configuration Files\n\n### Claude MCP Configuration (~/.claude.json)\n\n```json\n{\n \"mcpServers\": {\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\"]\n }\n }\n}\n```\n\n### With Options\n\n```json\n{\n \"mcpServers\": {\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\", \"--headless\", \"--browser\", \"chromium\", \"--viewport-size\", \"1280x720\"]\n }\n }\n}\n```\n\n### Environment Variables\n\nThe MCP server also supports environment variables:\n\n- `PLAYWRIGHT_MCP_BROWSER`: Browser type\n- `PLAYWRIGHT_MCP_HEADLESS`: Enable headless mode\n- `PLAYWRIGHT_MCP_ALLOWED_HOSTS`: Restrict accessible hosts\n\n---\n\n## Troubleshooting\n\n### Common Issues\n\n| Issue | Solution |\n| ------------------------------- | ---------------------------------------------- |\n| Claude uses Bash instead of MCP | Explicitly mention \"playwright mcp\" in request |\n| Browser not found | Run `npx playwright install` |\n| Permission errors | Pre-install browsers before running MCP |\n| Version conflicts | Use specific version instead of @latest |\n| Configuration not applied | Restart Claude Code after changes |\n\n### WSL/Linux Setup\n\n```bash\nsudo apt-get update\nsudo apt-get install -y chromium-browser\nexport CHROME_BIN=/usr/bin/chromium-browser\n```\n\n---\n\n## Conclusion\n\n### Recommended Default Setup\n\nFor most Claude Code CLI users, we recommend:\n\n```bash\n# Primary: MCP approach (simplest, most integrated)\nclaude mcp add playwright npx @playwright/mcp@latest\n\n# Pre-install browsers\nnpx playwright install\n```\n\n### For High-Performance/Production Environments\n\n```bash\n# CLI + Skills for token efficiency\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n\n# Plus MCP for interactive debugging\nclaude mcp add playwright npx @playwright/mcp@latest\n```\n\n### Key Takeaways\n\n1. **No `--tool claude` flag exists** - the commands in the issue work independently\n2. **MCP is simpler** for most users and recommended by official documentation\n3. **CLI + Skills is more token-efficient** for high-throughput scenarios\n4. **Both approaches are valid** and can be used together\n5. **Pre-installing browsers** is a best practice for both approaches\n\n---\n\n## Update (2026-03-14): Claude Code Plugins Ecosystem\n\n### Background\n\nClaude Code introduced a **plugin system** (v1.0.33+) that packages skills, agents, hooks, and MCP servers into installable, shareable bundles distributed via Git-based marketplaces. This section addresses the follow-up questions about how Claude Code plugins relate to Playwright MCP.\n\n### Three Approaches to Playwright in Claude Code (2026)\n\nThere are now **three** distinct approaches for using Playwright with Claude Code:\n\n| # | Approach | Installation | How It Works |\n|---|----------|-------------|-------------|\n| 1 | **Playwright MCP** (manual) | `claude mcp add playwright npx @playwright/mcp@latest` | Registers Microsoft's MCP server directly in `~/.claude.json` |\n| 2 | **Playwright Plugin** (official marketplace) | `/plugin install playwright@claude-plugins-official` | Installs the same MCP server, but packaged as a plugin |\n| 3 | **Playwright Skill** (community) | `/plugin marketplace add lackeyjb/playwright-skill` then `/plugin install playwright-skill@playwright-skill` | Claude writes and executes Playwright code directly (no MCP server) |\n\n### Approach 2: Official Playwright Plugin (Details)\n\nThe **official Playwright plugin** in `claude-plugins-official` (102,750+ installs, by Microsoft) is a thin wrapper around the same `@playwright/mcp@latest` MCP server. Its `plugin.json`:\n\n```json\n{\n \"name\": \"playwright\",\n \"description\": \"Browser automation and end-to-end testing MCP server by Microsoft. Enables Claude to interact with web pages, take screenshots, fill forms, click elements, and perform automated browser testing workflows.\",\n \"author\": { \"name\": \"Microsoft\" }\n}\n```\n\nIts `.mcp.json`:\n\n```json\n{\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\"]\n }\n}\n```\n\n**Key insight**: Approaches 1 and 2 are functionally identical — the plugin simply provides a managed installation experience via the plugin system. The underlying MCP server is the same.\n\n### Approach 3: Playwright Skill Plugin (Details)\n\nThe **community Playwright Skill** by [lackeyjb](https://github.com/lackeyjb/playwright-skill) takes a fundamentally different approach:\n\n- **Instead of MCP tools**: Claude writes custom Playwright code and executes it\n- **Returns**: Screenshots and console output (not accessibility tree snapshots)\n- **Token usage**: ~314 lines of skill instructions vs. a persistent MCP server\n- **Best for**: \"Scriptable manual testing\" during local development — quick validation like \"does my new feature work?\"\n- **Not designed for**: Comprehensive CI/CD test suites\n\nInstallation:\n\n```bash\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\n### Frontend-Design Plugin: NOT Related to Playwright\n\nThe `frontend-design` plugin (by Anthropic, 324,000+ installs) is a **design aesthetics skill** that helps Claude create visually distinctive UI code. It has **no Playwright dependency** and **no browser automation capability**. It auto-activates when Claude detects frontend development tasks and guides bold design choices (typography, color, animation, layout).\n\n### Correct Plugin Install Commands\n\nThe commands mentioned in the PR comment are **not correct**. Here are the correct commands:\n\n| Incorrect Command | Correct Alternative |\n|---|---|\n| `claude plugin install @anthropic/frontend-design` | `/plugin install frontend-design@claude-plugins-official` |\n| `/plugin install frontend-design@anthropics-claude-code` | `/plugin install frontend-design@claude-plugins-official` |\n\n**Correct syntax**: `/plugin install {plugin-name}@{marketplace-name}`\n\nThe official Anthropic marketplace is `claude-plugins-official` (pre-configured, no need to add it). The demo marketplace at `anthropics/claude-code` must be added first with `/plugin marketplace add anthropics/claude-code`.\n\n### Can Playwright MCP and Playwright Plugin Coexist?\n\n**Yes, but they shouldn't be used simultaneously.** Since the official Playwright plugin wraps the same MCP server, running both would create a duplicate `playwright` MCP registration. Choose one:\n\n| Scenario | Recommended Approach |\n|---|---|\n| Simple setup, want managed updates | `/plugin install playwright@claude-plugins-official` |\n| Custom MCP arguments (headless, viewport, browser) | `claude mcp add playwright npx @playwright/mcp@latest -- --headless` |\n| Token-efficient scriptable testing | `/plugin install playwright-skill@playwright-skill` (community) |\n| Maximum flexibility | MCP (manual) + Playwright Skill plugin (these are complementary) |\n\n**The MCP-based approaches (1 and 2) and the Skill approach (3) CAN coexist** because they use different mechanisms:\n- MCP: Provides browser automation tools that Claude calls\n- Skill: Provides instructions that Claude uses to write and execute Playwright scripts directly\n\n### Plugin Management Commands\n\n```bash\n# List installed plugins\n/plugin list\n\n# Browse available plugins interactively\n/plugin\n\n# Install from official marketplace (pre-configured)\n/plugin install playwright@claude-plugins-official\n/plugin install frontend-design@claude-plugins-official\n\n# Add a third-party marketplace\n/plugin marketplace add lackeyjb/playwright-skill\n\n# Install from third-party marketplace\n/plugin install playwright-skill@playwright-skill\n\n# Disable/enable/remove plugins\n/plugin disable playwright@claude-plugins-official\n/plugin enable playwright@claude-plugins-official\n/plugin uninstall playwright@claude-plugins-official\n\n# Reload after changes\n/reload-plugins\n```\n\n### Updated Recommendations (2026-03)\n\nFor most users, the simplest path is now:\n\n```bash\n# Install official Playwright plugin (wraps MCP server)\n/plugin install playwright@claude-plugins-official\n\n# Pre-install browsers\nnpx playwright install\n```\n\nFor advanced users wanting both MCP tools AND efficient scripted testing:\n\n```bash\n# Option A: Official plugin for MCP tools\n/plugin install playwright@claude-plugins-official\n\n# Option B: Community skill for script-based testing\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\nFor frontend design quality (unrelated to Playwright):\n\n```bash\n/plugin install frontend-design@claude-plugins-official\n```\n\n---\n\n## References\n\n### Official Documentation\n\n- [Microsoft Playwright MCP Repository](https://github.com/microsoft/playwright-mcp)\n- [Microsoft Playwright CLI Repository](https://github.com/microsoft/playwright-cli)\n- [Anthropic Model Context Protocol](https://www.anthropic.com/engineering/code-execution-with-mcp)\n\n### Tutorials & Guides\n\n- [Simon Willison: Using Playwright MCP with Claude Code](https://til.simonwillison.net/claude-code/playwright-mcp-claude-code)\n- [Supatest: Playwright MCP Setup Guide](https://supatest.ai/blog/playwright-mcp-setup-guide)\n- [Testomat: Playwright MCP Claude Code](https://testomat.io/blog/playwright-mcp-claude-code/)\n\n### Comparative Analysis\n\n- [CosmicJS: MCP vs Skills Guide](https://www.cosmicjs.com/blog/mcp-vs-skills-ai-coding-assistant-integrations-guide)\n- [IntuitionLabs: Claude Skills vs MCP](https://intuitionlabs.ai/articles/claude-skills-vs-mcp)\n- [CLI-Agent vs MCP Practical Comparison](https://medium.com/@girmish/cli-agent-vs-mcp-a-practical-comparison-for-students-startups-and-developers-2026-b9fe30a96559)\n\n### Alternative Implementations\n\n- [ExecuteAutomation MCP-Playwright](https://github.com/executeautomation/mcp-playwright)\n- [lackeyjb/playwright-skill](https://github.com/lackeyjb/playwright-skill)\n",

"originalFile": "# Case Study: Playwright MCP Best Practices for Claude Code CLI\n\n## Issue Reference\n\n- **Issue**: https://github.com/link-assistant/hive-mind/issues/1284\n- **Date**: 2026-02-13\n- **Tags**: documentation, enhancement, question\n- **Author**: konard\n\n## Executive Summary\n\nThis case study investigates the best practices for using Playwright with Claude Code CLI, comparing two primary approaches:\n\n1. **MCP (Model Context Protocol)**: `claude mcp add playwright npx @playwright/mcp@latest`\n2. **CLI + Skills**: `playwright-cli install --skills`\n\nOur research concludes that **both approaches have valid use cases**, and the optimal choice depends on the specific workflow requirements. For most Claude Code CLI users, the **MCP approach is currently the recommended default**, while the CLI + Skills approach offers advantages for high-throughput, token-efficient scenarios.\n\n---\n\n## The Question\n\nThe issue asks:\n\n> Do we actually use all these with `--tool claude`? Is there any better practices in the internet?\n>\n> ```\n> playwright-cli install --skills\n> claude mcp add playwright npx @playwright/mcp@latest\n> ```\n\n### Analysis of the Commands\n\n1. **`playwright-cli install --skills`**: This command installs Skills documentation files to `~/.skills/playwright-cli/` for coding agents to understand and use playwright-cli commands efficiently.\n\n2. **`claude mcp add playwright npx @playwright/mcp@latest`**: This command registers the official Microsoft Playwright MCP server with Claude Code, enabling browser automation tools.\n\n**Important Clarification**: The `--tool claude` flag is **not a valid flag** for either command. The commands mentioned in the issue work independently.\n\n---\n\n## Two Approaches: MCP vs CLI + Skills\n\n### Approach 1: Playwright MCP Server (Recommended for Most Users)\n\n**Installation**:\n\n```bash\nclaude mcp add playwright npx @playwright/mcp@latest\n```\n\n**How it works**:\n\n- Registers the official Microsoft Playwright MCP server with Claude Code\n- Provides 25+ browser automation tools directly accessible to Claude\n- Uses the Model Context Protocol standard developed by Anthropic\n\n**Key Features**:\n\n- Real-time browser control through accessibility snapshots\n- Visible browser window for authentication and debugging\n- Session persistence with cookies and local storage\n- Extensive configuration options (headless mode, viewport, proxy, etc.)\n\n**Available Tools** (partial list):\n\n- `browser_navigate`, `browser_navigate_back`\n- `browser_click`, `browser_type`, `browser_drag`\n- `browser_take_screenshot`, `browser_snapshot`\n- `browser_fill_form`, `browser_select_option`\n- `browser_wait_for`, `browser_tabs`\n- `browser_evaluate`, `browser_run_code`\n\n### Approach 2: Playwright CLI + Skills\n\n**Installation**:\n\n```bash\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n```\n\n**How it works**:\n\n- Installs Skills documentation to `~/.skills/playwright-cli/`\n- Claude Code reads these skill files for command understanding\n- CLI commands are invoked directly without an MCP server\n\n**Key Features**:\n\n- More token-efficient (avoids loading large tool schemas)\n- Works offline with static documentation\n- 40+ CLI commands across browser control, interaction, storage, network\n- Session management for parallel workflows\n\n---\n\n## Comparative Analysis\n\n### Feature Comparison\n\n| Feature | MCP Approach | CLI + Skills Approach |\n| --------------------- | -------------------------- | ----------------------------- |\n| **Setup Complexity** | Low (single command) | Medium (two commands) |\n| **Token Efficiency** | Lower (loads tool schemas) | Higher (33% savings reported) |\n| **Real-time Control** | Yes | Yes |\n| **Offline Support** | No | Yes (Skills are static) |\n| **Tool Discovery** | Automatic | Via `--help` or Skills docs |\n| **Maintenance** | Automatic with @latest | Manual CLI updates |\n| **Authentication** | Easy (visible browser) | Same capability |\n| **CI/CD Integration** | Good | Better |\n\n### Performance Metrics\n\nAccording to benchmarks and research:\n\n- **MCP**: Provides \"70% memory reduction\" through accessibility trees vs screenshots\n- **CLI + Skills**: Offers \"33% token savings\" in developer tasks due to avoided schema loading\n\n### Use Case Recommendations\n\n**Choose MCP when**:\n\n- You want the simplest setup\n- You need real-time browser interaction\n- You're doing exploratory testing or debugging\n- Authentication through visible browser is valuable\n- You prefer automatic tool discovery\n\n**Choose CLI + Skills when**:\n\n- Token efficiency is critical (large codebases)\n- You need offline capability\n- CI/CD pipeline integration is important\n- You want explicit control over commands\n- High-throughput automation is required\n\n---\n\n## Best Practices\n\n### For MCP Approach\n\n1. **Installation**:\n\n ```bash\n # Global (affects all directories)\n claude mcp add -s user playwright npx '@playwright/mcp@latest'\n\n # Project-specific\n claude mcp add playwright npx '@playwright/mcp@latest'\n ```\n\n2. **First Usage**: Explicitly mention \"playwright mcp\" in your first request:\n\n > \"Use playwright mcp to open a browser to example.com\"\n\n3. **Configuration Options**:\n\n ```bash\n # Headless mode for CI\n claude mcp add playwright npx @playwright/mcp@latest -- --headless\n\n # Specific browser\n claude mcp add playwright npx @playwright/mcp@latest -- --browser firefox\n\n # Custom viewport\n claude mcp add playwright npx @playwright/mcp@latest -- --viewport-size 1920x1080\n ```\n\n4. **Pre-install browsers** (recommended):\n\n ```bash\n npx playwright install\n npx playwright install-deps # Linux\n ```\n\n5. **Authentication Strategy**: Let Claude show you the login page, authenticate manually, then continue automation.\n\n### For CLI + Skills Approach\n\n1. **Installation**:\n\n ```bash\n npm install -g @playwright/cli@latest\n playwright-cli install --skills\n ```\n\n2. **Skills Location**: `~/.skills/playwright-cli/`\n - `SKILL.md`: Primary documentation\n - `references/*.md`: Detailed guides for specific tasks\n\n3. **Session Management**: Use `-s=name` flags for parallel isolated sessions.\n\n### Security Best Practices (Both Approaches)\n\n1. **Permission Awareness**: MCP servers execute with user permissions\n2. **Isolated Environments**: Use dedicated test environments\n3. **Audit Commands**: Review AI-generated automation before production use\n4. **Version Pinning**: Consider using specific versions instead of @latest in production\n\n---\n\n## Alternative Solutions & Libraries\n\n### 1. ExecuteAutomation's MCP-Playwright\n\n**Repository**: https://github.com/executeautomation/mcp-playwright\n\n**Installation**:\n\n```bash\nnpx @smithery/cli install @executeautomation/playwright-mcp-server --client claude\n```\n\n**Features**: Extended MCP implementation with additional automation capabilities.\n\n### 2. lackeyjb/playwright-skill\n\n**Repository**: https://github.com/lackeyjb/playwright-skill\n\n**Installation**:\n\n```bash\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\n**Features**: Model-invoked skill where Claude autonomously writes and executes custom Playwright code.\n\n### 3. Hybrid Approach\n\nFor production environments, consider combining both:\n\n```bash\n# MCP for real-time interactive debugging\nclaude mcp add playwright npx @playwright/mcp@latest\n\n# Skills for efficient scripted automation\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n```\n\n---\n\n## Configuration Files\n\n### Claude MCP Configuration (~/.claude.json)\n\n```json\n{\n \"mcpServers\": {\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\"]\n }\n }\n}\n```\n\n### With Options\n\n```json\n{\n \"mcpServers\": {\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\", \"--headless\", \"--browser\", \"chromium\", \"--viewport-size\", \"1280x720\"]\n }\n }\n}\n```\n\n### Environment Variables\n\nThe MCP server also supports environment variables:\n\n- `PLAYWRIGHT_MCP_BROWSER`: Browser type\n- `PLAYWRIGHT_MCP_HEADLESS`: Enable headless mode\n- `PLAYWRIGHT_MCP_ALLOWED_HOSTS`: Restrict accessible hosts\n\n---\n\n## Troubleshooting\n\n### Common Issues\n\n| Issue | Solution |\n| ------------------------------- | ---------------------------------------------- |\n| Claude uses Bash instead of MCP | Explicitly mention \"playwright mcp\" in request |\n| Browser not found | Run `npx playwright install` |\n| Permission errors | Pre-install browsers before running MCP |\n| Version conflicts | Use specific version instead of @latest |\n| Configuration not applied | Restart Claude Code after changes |\n\n### WSL/Linux Setup\n\n```bash\nsudo apt-get update\nsudo apt-get install -y chromium-browser\nexport CHROME_BIN=/usr/bin/chromium-browser\n```\n\n---\n\n## Conclusion\n\n### Recommended Default Setup\n\nFor most Claude Code CLI users, we recommend:\n\n```bash\n# Primary: MCP approach (simplest, most integrated)\nclaude mcp add playwright npx @playwright/mcp@latest\n\n# Pre-install browsers\nnpx playwright install\n```\n\n### For High-Performance/Production Environments\n\n```bash\n# CLI + Skills for token efficiency\nnpm install -g @playwright/cli@latest\nplaywright-cli install --skills\n\n# Plus MCP for interactive debugging\nclaude mcp add playwright npx @playwright/mcp@latest\n```\n\n### Key Takeaways\n\n1. **No `--tool claude` flag exists** - the commands in the issue work independently\n2. **MCP is simpler** for most users and recommended by official documentation\n3. **CLI + Skills is more token-efficient** for high-throughput scenarios\n4. **Both approaches are valid** and can be used together\n5. **Pre-installing browsers** is a best practice for both approaches\n\n---\n\n## Update (2026-03-14): Claude Code Plugins Ecosystem\n\n### Background\n\nClaude Code introduced a **plugin system** (v1.0.33+) that packages skills, agents, hooks, and MCP servers into installable, shareable bundles distributed via Git-based marketplaces. This section addresses the follow-up questions about how Claude Code plugins relate to Playwright MCP.\n\n### Three Approaches to Playwright in Claude Code (2026)\n\nThere are now **three** distinct approaches for using Playwright with Claude Code:\n\n| # | Approach | Installation | How It Works |\n|---|----------|-------------|-------------|\n| 1 | **Playwright MCP** (manual) | `claude mcp add playwright npx @playwright/mcp@latest` | Registers Microsoft's MCP server directly in `~/.claude.json` |\n| 2 | **Playwright Plugin** (official marketplace) | `/plugin install playwright@claude-plugins-official` | Installs the same MCP server, but packaged as a plugin |\n| 3 | **Playwright Skill** (community) | `/plugin marketplace add lackeyjb/playwright-skill` then `/plugin install playwright-skill@playwright-skill` | Claude writes and executes Playwright code directly (no MCP server) |\n\n### Approach 2: Official Playwright Plugin (Details)\n\nThe **official Playwright plugin** in `claude-plugins-official` (102,750+ installs, by Microsoft) is a thin wrapper around the same `@playwright/mcp@latest` MCP server. Its `plugin.json`:\n\n```json\n{\n \"name\": \"playwright\",\n \"description\": \"Browser automation and end-to-end testing MCP server by Microsoft. Enables Claude to interact with web pages, take screenshots, fill forms, click elements, and perform automated browser testing workflows.\",\n \"author\": { \"name\": \"Microsoft\" }\n}\n```\n\nIts `.mcp.json`:\n\n```json\n{\n \"playwright\": {\n \"command\": \"npx\",\n \"args\": [\"@playwright/mcp@latest\"]\n }\n}\n```\n\n**Key insight**: Approaches 1 and 2 are functionally identical — the plugin simply provides a managed installation experience via the plugin system. The underlying MCP server is the same.\n\n### Approach 3: Playwright Skill Plugin (Details)\n\nThe **community Playwright Skill** by [lackeyjb](https://github.com/lackeyjb/playwright-skill) takes a fundamentally different approach:\n\n- **Instead of MCP tools**: Claude writes custom Playwright code and executes it\n- **Returns**: Screenshots and console output (not accessibility tree snapshots)\n- **Token usage**: ~314 lines of skill instructions vs. a persistent MCP server\n- **Best for**: \"Scriptable manual testing\" during local development — quick validation like \"does my new feature work?\"\n- **Not designed for**: Comprehensive CI/CD test suites\n\nInstallation:\n\n```bash\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\n### Frontend-Design Plugin: NOT Related to Playwright\n\nThe `frontend-design` plugin (by Anthropic, 324,000+ installs) is a **design aesthetics skill** that helps Claude create visually distinctive UI code. It has **no Playwright dependency** and **no browser automation capability**. It auto-activates when Claude detects frontend development tasks and guides bold design choices (typography, color, animation, layout).\n\n### Correct Plugin Install Commands\n\nThe commands mentioned in the PR comment are **not correct**. Here are the correct commands:\n\n| Incorrect Command | Correct Alternative |\n|---|---|\n| `claude plugin install @anthropic/frontend-design` | `/plugin install frontend-design@claude-plugins-official` |\n| `/plugin install frontend-design@anthropics-claude-code` | `/plugin install frontend-design@claude-plugins-official` |\n\n**Correct syntax**: `/plugin install {plugin-name}@{marketplace-name}`\n\nThe official Anthropic marketplace is `claude-plugins-official` (pre-configured, no need to add it). The demo marketplace at `anthropics/claude-code` must be added first with `/plugin marketplace add anthropics/claude-code`.\n\n### Can Playwright MCP and Playwright Plugin Coexist?\n\n**Yes, but they shouldn't be used simultaneously.** Since the official Playwright plugin wraps the same MCP server, running both would create a duplicate `playwright` MCP registration. Choose one:\n\n| Scenario | Recommended Approach |\n|---|---|\n| Simple setup, want managed updates | `/plugin install playwright@claude-plugins-official` |\n| Custom MCP arguments (headless, viewport, browser) | `claude mcp add playwright npx @playwright/mcp@latest -- --headless` |\n| Token-efficient scriptable testing | `/plugin install playwright-skill@playwright-skill` (community) |\n| Maximum flexibility | MCP (manual) + Playwright Skill plugin (these are complementary) |\n\n**The MCP-based approaches (1 and 2) and the Skill approach (3) CAN coexist** because they use different mechanisms:\n- MCP: Provides browser automation tools that Claude calls\n- Skill: Provides instructions that Claude uses to write and execute Playwright scripts directly\n\n### Plugin Management Commands\n\n```bash\n# List installed plugins\n/plugin list\n\n# Browse available plugins interactively\n/plugin\n\n# Install from official marketplace (pre-configured)\n/plugin install playwright@claude-plugins-official\n/plugin install frontend-design@claude-plugins-official\n\n# Add a third-party marketplace\n/plugin marketplace add lackeyjb/playwright-skill\n\n# Install from third-party marketplace\n/plugin install playwright-skill@playwright-skill\n\n# Disable/enable/remove plugins\n/plugin disable playwright@claude-plugins-official\n/plugin enable playwright@claude-plugins-official\n/plugin uninstall playwright@claude-plugins-official\n\n# Reload after changes\n/reload-plugins\n```\n\n### Updated Recommendations (2026-03)\n\nFor most users, the simplest path is now:\n\n```bash\n# Install official Playwright plugin (wraps MCP server)\n/plugin install playwright@claude-plugins-official\n\n# Pre-install browsers\nnpx playwright install\n```\n\nFor advanced users wanting both MCP tools AND efficient scripted testing:\n\n```bash\n# Option A: Official plugin for MCP tools\n/plugin install playwright@claude-plugins-official\n\n# Option B: Community skill for script-based testing\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\ncd ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill\nnpm run setup\n```\n\nFor frontend design quality (unrelated to Playwright):\n\n```bash\n/plugin install frontend-design@claude-plugins-official\n```\n\n---\n\n## References\n\n### Official Documentation\n\n- [Microsoft Playwright MCP Repository](https://github.com/microsoft/playwright-mcp)\n- [Microsoft Playwright CLI Repository](https://github.com/microsoft/playwright-cli)\n- [Anthropic Model Context Protocol](https://www.anthropic.com/engineering/code-execution-with-mcp)\n\n### Tutorials & Guides\n\n- [Simon Willison: Using Playwright MCP with Claude Code](https://til.simonwillison.net/claude-code/playwright-mcp-claude-code)\n- [Supatest: Playwright MCP Setup Guide](https://supatest.ai/blog/playwright-mcp-setup-guide)\n- [Testomat: Playwright MCP Claude Code](https://testomat.io/blog/playwright-mcp-claude-code/)\n\n### Comparative Analysis\n\n- [CosmicJS: MCP vs Skills Guide](https://www.cosmicjs.com/blog/mcp-vs-skills-ai-coding-assistant-integrations-guide)\n- [IntuitionLabs: Claude Skills vs MCP](https://intuitionlabs.ai/articles/claude-skills-vs-mcp)\n- [CLI-Agent vs MCP Practical Comparison](https://medium.com/@girmish/cli-agent-vs-mcp-a-practical-comparison-for-students-startups-and-developers-2026-b9fe30a96559)\n\n### Claude Code Plugins Documentation\n\n- [Create plugins - Claude Code Docs](https://code.claude.com/docs/en/plugins)\n- [Discover and install plugins - Claude Code Docs](https://code.claude.com/docs/en/discover-plugins)\n- [Frontend Design Plugin (GitHub)](https://github.com/anthropics/claude-code/tree/main/plugins/frontend-design)\n- [Frontend Design Plugin (Official)](https://claude.com/plugins/frontend-design)\n- [Playwright Plugin (Official)](https://claude.com/plugins/playwright)\n- [Playwright Plugin Source (claude-plugins-official)](https://github.com/anthropics/claude-plugins-official/tree/main/external_plugins/playwright)\n\n### Alternative Implementations\n\n- [ExecuteAutomation MCP-Playwright](https://github.com/executeautomation/mcp-playwright)\n- [lackeyjb/playwright-skill](https://github.com/lackeyjb/playwright-skill)\n- [Playwright Skill HN Discussion](https://news.ycombinator.com/item?id=45642911)\n",

The community Playwright Skill (approach 3) IS complementary and can be used alongside either.\n\n### Files Changed\n\n- `docs/case-studies/issue-1284/README.md` - Comprehensive case study with:\n - Original MCP vs CLI+Skills analysis\n - **NEW**: Claude Code plugins ecosystem section (2026-03-14)\n - Feature comparison tables for all approaches\n - Correct plugin commands and coexistence guide\n - Security and troubleshooting recommendations\n\n- `docs/case-studies/issue-1284/research-sources.md` - All 20+ research sources consulted\n\n- `.changeset/playwright-mcp-best-practices.md` - Changeset for version bump\n\n## Recommendations\n\nFor most Claude Code CLI users (simplest path):\n```bash\n# Install official Playwright plugin (wraps MCP server)\n/plugin install playwright@claude-plugins-official\n\n# Pre-install browsers\nnpx playwright install\n```\n\nFor advanced users wanting both MCP tools AND efficient scripted testing:\n```bash\n# Official plugin for MCP-based browser automation\n/plugin install playwright@claude-plugins-official\n\n# Community skill for script-based testing (complementary)\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\n```\n\n## Test Plan\n\n- [x] Verify case study follows existing format in `docs/case-studies/`\n- [x] Verify all plugin commands against official documentation\n- [x] Confirm official Playwright plugin wraps same MCP server (verified `.mcp.json` source)\n- [x] Confirm frontend-design plugin has no Playwright dependency (verified `SKILL.md` source)\n- [x] Ensure changeset is properly formatted\n\nFixes #1284\n\n---\n🤖 Generated with [Claude Code](https://claude.com/claude-code)\nPREOF\n)\" 2>&1",

Are Claude Code plugins better than Playwright MCP?**\n\nThe **official Playwright plugin** (`/plugin install playwright@claude-plugins-official`, 102K+ installs, by Microsoft) is a thin wrapper around the **same** `@playwright/mcp@latest` MCP server. Verified from source — its `.mcp.json` is literally `{\"playwright\": {\"command\": \"npx\", \"args\": [\"@playwright/mcp@latest\"]}}`. So it's functionally identical, just packaged for easier management via the plugin system.\n\nThe **community Playwright Skill** ([lackeyjb/playwright-skill](https://github.com/lackeyjb/playwright-skill)) takes a different approach — Claude writes and executes Playwright code directly instead of using MCP tools. It's more token-efficient (~314 lines of instructions) but designed for \"scriptable manual testing\", not CI/CD.\n\n**2. The `frontend-design` plugin is NOT related to Playwright.** It's an Anthropic design aesthetics skill (324K+ installs) that helps Claude create visually distinctive UI code. No browser automation capability.\n\n**3. Correct plugin install commands:**\n\n| Incorrect | Correct |\n|---|---|\n| `claude plugin install @anthropic/frontend-design` | `/plugin install frontend-design@claude-plugins-official` |\n| `/plugin install frontend-design@anthropics-claude-code` | `/plugin install frontend-design@claude-plugins-official` |\n\nSyntax: `/plugin install {plugin-name}@{marketplace-name}`. The official marketplace is `claude-plugins-official` (pre-configured).\n\n**4. Can both Playwright MCP and Playwright Plugin coexist?**\n\n- MCP (manual) + Plugin (official) = ❌ redundant (same MCP server, would conflict)\n- MCP/Plugin + Playwright Skill (community) = ✅ complementary (different mechanisms)\n\n**5. Recommended setup:**\n\n```bash\n# Simplest: official plugin\n/plugin install playwright@claude-plugins-official\nnpx playwright install\n\n# Optional: add community skill for script-based testing\n/plugin marketplace add lackeyjb/playwright-skill\n/plugin install playwright-skill@playwright-skill\n```\n\nAll findings have been added to the case study in `docs/case-studies/issue-1284/README.md`.\n\nSources: [Claude Code Plugins Docs](https://code.claude.com/docs/en/plugins) · [Discover Plugins Docs](https://code.claude.com/docs/en/discover-plugins) · [Official Playwright Plugin Source](https://github.com/anthropics/claude-plugins-official/tree/main/external_plugins/playwright) · [Frontend Design Plugin](https://github.com/anthropics/claude-code/tree/main/plugins/frontend-design) · [Playwright Skill HN](https://news.ycombinator.com/item?id=45642911)\nCOMMENT\n)\" 2>&1",
