Dzhuneyt / migrate-claude-code-slash-commands-to-skills.md
Created April 24, 2026 07:55
Migrate Claude Code slash commands to skills

Migrate my local Claude Code slash commands to Skills.

Context: Claude Code recently unified slash commands and Skills into a single runtime namespace. Slash commands live at ~/.claude/commands/*.md; skills live at ~/.claude/skills/<name>/SKILL.md. Skills support richer frontmatter (allowed-tools, disable-model-invocation, argument-hint), live reload, and optional model auto-invocation. Commands still work but are legacy. Docs: https://code.claude.com/docs/en/skills

Do this end-to-end, pausing only at the decision points I call out:

Phase 1 — Audit (read-only)

  1. List every file in ~/.claude/commands/ (including nested dirs). For each .md, capture: full YAML frontmatter, body line count, whether it uses $ARGUMENTS, and whether it uses shell-injection syntax (!`...`).
  2. List every subdir in ~/.claude/skills/ with its SKILL.md frontmatter.
