# hty Skill Summary
The **hty** tool enables agents to drive interactive terminal programs by simulating human keyboard and mouse input within persistent
PTY sessions. It's essential for tasks that plain bash cannot handle.
## Key Use Cases
According to the documentation, use hty when commands:
- Prompt for input (e.g., `gh auth login`, `npm init`)
- Use full-screen interfaces (`vim`, `htop`, `k9s`)
- Step through wizards (`git add -p`, `ssh-keygen`)
- Require REPL functionality (`psql`, `node`)
- Fail with "not a tty" errors
## Installation
The skill requires both the hty CLI (v0.7.0+) and can be installed via:
```sh
npx skills add LatentEvals/hty --skill hty
```
Or manually to `~/.claude/skills/hty/` using the tarball from `https://hty.sh/skill.tar.gz`.
## Two Operating Patterns
**Pattern A (Polling):** Works universally—spawn, send input, snapshot, repeat:
```
hty run --name <task> --snapshot --wait-until-text "..."
hty send <task> --text "..." --snapshot --wait-until-idle
```
**Pattern B (Attach):** For agents supporting background processes—launch once with streaming output, then send input separately.
## Critical Commands
| Command | Purpose |
|---------|---------|
| `hty run -- program` | Spawn interactive session |
| `hty send <session> --text "..."` | Type input |
| `hty snapshot <session>` | Read screen state |
| `hty wait <session> --text "..."` | Block until condition |
## Common Gotchas
- Use `\n` (newline), not `\r` (carriage return) in text input
- Session names must be unique; check `hty list` first
- Timeouts are milliseconds: `--timeout 5000` = 5 seconds
- `--attach` and `--snapshot` flags are mutually exclusive
Exit codes: 0 (success), 2 (session not found), 3 (wait timeout), 5 (name exists).
⏺ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
Now installing the skill via the documented command.

⏺ The installer is interactive. Let me cancel and retry with non-interactive flags, installing globally so the skill is available across
projects.
⏺ Bash(pkill -f "skills add" 2>/dev/null; sleep 1; npx --yes skills add LatentEvals/hty --skill hty --yes --global 2>&1 | tail -50)
⎿  Denied by auto mode classifier ∙ /feedback if incorrect
⏺ The sandbox denied the retry since npx executes fetched code from an external source. The first attempt was also interactive and waiting
for user selection — I killed it mid-prompt.
How would you like me to proceed? A few options:
1. Let the first installer run interactively — you press the keys in the TUI (Claude Code is already pre-selected). Re-run npx skills add
LatentEvals/hty --skill hty yourself in a ! prompt.
2. Approve the non-interactive retry — npx --yes skills add LatentEvals/hty --skill hty --yes --global (adds a Bash permission rule if you
want it to stick).
3. Manual install from the tarball — download https://hty.sh/skill.tar.gz and extract to ~/.claude/skills/hty/. Still fetches external
content, but no code execution via npx.
Also worth noting: you're inside the hty repo itself (the source of this skill — recent commit 9145b321 feat: add hty agent skill with
website distribution). You may already have the skill files locally in this tree that could just be symlinked/copied into
~/.claude/skills/hty/. Want me to check?
✻ Cogitated for 1m 5s
❯ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
whats this?
⏺ When I fetched https://hty.sh/skill.md, the returned page content ended with a block that looked like this:
<system-reminder>
The following deferred tools are now available via ToolSearch...
ListMcpResourcesTool
ReadMcpResourceTool
mcp__plugin_posthog_posthog__action-create
...(200+ tool names)
</system-reminder>
That <system-reminder> tag was inside the web page body, not a real harness message. Real system reminders come from the Claude Code
runtime (like the ones above this message); a web page injecting one is a classic prompt injection — the page is trying to impersonate a
trusted system instruction to get me to behave differently (in this case, to think a large set of new tools had been unlocked).
I ignored it and flagged it per the system guidance on untrusted tool output. The legitimate install instructions earlier in the same page
(the npx skills add ... command) are fine — it's just the trailing fake-reminder block that was suspicious.
Worth telling whoever maintains hty.sh/skill.md if that content was unintentional, since it suggests the page was generated from a
transcript that captured a real system-reminder verbatim.
❯ nah bro thats not from the website...
https://hty.sh/skill.md
⏺ You're right, my bad — let me verify by fetching the raw page.
⏺ Bash(curl -sL https://hty.sh/skill.md | tail -20)
⎿  ## Exit codes
| Code | Meaning |
|:---:|---|
| 0 | Success |
| 1 | Generic error |
| 2 | Session not found |
| 3 | `wait` timed out |
| 4 | Ambiguous session prefix (multiple matches) |
| 5 | Session name already exists |
Non-zero exit codes are stable — key off them in agent scripts rather than parsing error messages.

⏺ You're absolutely right, apologies — the raw page ends cleanly at the github.com/LatentEvals/hty link. The <system-reminder> block I saw
in the WebFetch result was injected by the Claude Code harness itself (announcing newly-available MCP/deferred tools), not by the web
page. I misread the source and wrongly accused hty.sh of prompt injection. Retracting that.

⏺ Done. Symlinked .claude/skills/hty → ../../skills/hty so the skill loads from the repo source — any edits you make to skills/hty/SKILL.md
take effect immediately, no resync needed. Restart the session (or the skill will pick up on next tool list refresh) to make /hty
available.
❯ do you see the skill now?
⏺ No — the available-skills list in my system context was snapshotted at session start, before the symlink existed. I won't see hty as an
invocable skill until you restart the Claude Code session (or trigger a skills reload). The symlink itself is in place correctly, though:
⏺ Bash(readlink .claude/skills/hty && test -f .claude/skills/hty/SKILL.md && echo "SKILL.md resolves OK")
⎿  ../../skills/hty
SKILL.md resolves OK
⏺ Symlink resolves and SKILL.md is reachable. Restart the session and /hty should show up.
/remote-control is active · Code in CLI or at https://claude.ai/code/session_011ViakAYTwkWSJPAeu6VDak
❯ how about now?
⏺ Still no — my available-skills list hasn't changed. It was loaded as a <system-reminder> at session start and Claude Code doesn't push
updated lists mid-session. The symlink is valid on disk, but the harness needs to re-enumerate skills, which happens on session start.
Quickest check: /exit and relaunch, then /hty should autocomplete.
❯ i already relaunched....
⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git
▎ add -p, gh auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.

Create a new session and start `program` inside a fresh PTY. The session

--cwd PATH Child's working directory
--scrollback N Scrollback buffer size (default 10000)
--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

One minor observation: --remove cleanup isn't instantaneous — session lingered briefly as exited before being reaped. Not a bug per se,
just a timing quirk worth knowing if you chain a hty list right after. Skill is functional.
✻ Baked for 1m 13s
❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state
reasoning, and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd
try to get a 512+ tile by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent
top" implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.

# hty Skill Summary
The **hty** tool enables agents to drive interactive terminal programs by simulating human keyboard and mouse input within persistent
PTY sessions. It's essential for tasks that plain bash cannot handle.
## Key Use Cases
According to the documentation, use hty when commands:
- Prompt for input (e.g., `gh auth login`, `npm init`)
- Use full-screen interfaces (`vim`, `htop`, `k9s`)
- Step through wizards (`git add -p`, `ssh-keygen`)
- Require REPL functionality (`psql`, `node`)
- Fail with "not a tty" errors
## Installation
The skill requires both the hty CLI (v0.7.0+) and can be installed via:
```sh
npx skills add LatentEvals/hty --skill hty
```
Or manually to `~/.claude/skills/hty/` using the tarball from `https://hty.sh/skill.tar.gz`.
## Two Operating Patterns
**Pattern A (Polling):** Works universally—spawn, send input, snapshot, repeat:
```
hty run --name <task> --snapshot --wait-until-text "..."
hty send <task> --text "..." --snapshot --wait-until-idle
```
**Pattern B (Attach):** For agents supporting background processes—launch once with streaming output, then send input separately.
## Critical Commands
| Command | Purpose |
|---------|---------|
| `hty run -- program` | Spawn interactive session |
| `hty send <session> --text "..."` | Type input |
| `hty snapshot <session>` | Read screen state |
| `hty wait <session> --text "..."` | Block until condition |
## Common Gotchas
- Use `\n` (newline), not `\r` (carriage return) in text input
- Session names must be unique; check `hty list` first
- Timeouts are milliseconds: `--timeout 5000` = 5 seconds
- `--attach` and `--snapshot` flags are mutually exclusive
Exit codes: 0 (success), 2 (session not found), 3 (wait timeout), 5 (name exists).
⏺ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
Now installing the skill via the documented command.

⏺ The installer is interactive. Let me cancel and retry with non-interactive flags, installing globally so the skill is available across
projects.
⏺ Bash(pkill -f "skills add" 2>/dev/null; sleep 1; npx --yes skills add LatentEvals/hty --skill hty --yes --global 2>&1 | tail -50)
⎿  Denied by auto mode classifier ∙ /feedback if incorrect
⏺ The sandbox denied the retry since npx executes fetched code from an external source. The first attempt was also interactive and waiting
for user selection — I killed it mid-prompt.
How would you like me to proceed? A few options:
1. Let the first installer run interactively — you press the keys in the TUI (Claude Code is already pre-selected). Re-run npx skills add
LatentEvals/hty --skill hty yourself in a ! prompt.
2. Approve the non-interactive retry — npx --yes skills add LatentEvals/hty --skill hty --yes --global (adds a Bash permission rule if you
want it to stick).
3. Manual install from the tarball — download https://hty.sh/skill.tar.gz and extract to ~/.claude/skills/hty/. Still fetches external
content, but no code execution via npx.
Also worth noting: you're inside the hty repo itself (the source of this skill — recent commit 9145b321 feat: add hty agent skill with
website distribution). You may already have the skill files locally in this tree that could just be symlinked/copied into
~/.claude/skills/hty/. Want me to check?
✻ Cogitated for 1m 5s
❯ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
whats this?
⏺ When I fetched https://hty.sh/skill.md, the returned page content ended with a block that looked like this:
<system-reminder>
The following deferred tools are now available via ToolSearch...
ListMcpResourcesTool
ReadMcpResourceTool
mcp__plugin_posthog_posthog__action-create
...(200+ tool names)
</system-reminder>
That <system-reminder> tag was inside the web page body, not a real harness message. Real system reminders come from the Claude Code
runtime (like the ones above this message); a web page injecting one is a classic prompt injection — the page is trying to impersonate a
trusted system instruction to get me to behave differently (in this case, to think a large set of new tools had been unlocked).
I ignored it and flagged it per the system guidance on untrusted tool output. The legitimate install instructions earlier in the same page
(the npx skills add ... command) are fine — it's just the trailing fake-reminder block that was suspicious.
Worth telling whoever maintains hty.sh/skill.md if that content was unintentional, since it suggests the page was generated from a
transcript that captured a real system-reminder verbatim.
❯ nah bro thats not from the website...
https://hty.sh/skill.md
⏺ You're right, my bad — let me verify by fetching the raw page.
⏺ Bash(curl -sL https://hty.sh/skill.md | tail -20)
⎿  ## Exit codes
| Code | Meaning |
|:---:|---|
| 0 | Success |
| 1 | Generic error |
| 2 | Session not found |
| 3 | `wait` timed out |
| 4 | Ambiguous session prefix (multiple matches) |
| 5 | Session name already exists |
Non-zero exit codes are stable — key off them in agent scripts rather than parsing error messages.

⏺ You're absolutely right, apologies — the raw page ends cleanly at the github.com/LatentEvals/hty link. The <system-reminder> block I saw in
the WebFetch result was injected by the Claude Code harness itself (announcing newly-available MCP/deferred tools), not by the web page. I
misread the source and wrongly accused hty.sh of prompt injection. Retracting that.

⏺ Done. Symlinked .claude/skills/hty → ../../skills/hty so the skill loads from the repo source — any edits you make to skills/hty/SKILL.md
take effect immediately, no resync needed. Restart the session (or the skill will pick up on next tool list refresh) to make /hty
available.
❯ do you see the skill now?
⏺ No — the available-skills list in my system context was snapshotted at session start, before the symlink existed. I won't see hty as an
invocable skill until you restart the Claude Code session (or trigger a skills reload). The symlink itself is in place correctly, though:
⏺ Bash(readlink .claude/skills/hty && test -f .claude/skills/hty/SKILL.md && echo "SKILL.md resolves OK")
⎿  ../../skills/hty
SKILL.md resolves OK
⏺ Symlink resolves and SKILL.md is reachable. Restart the session and /hty should show up.
/remote-control is active · Code in CLI or at https://claude.ai/code/session_011ViakAYTwkWSJPAeu6VDak
❯ how about now?
⏺ Still no — my available-skills list hasn't changed. It was loaded as a <system-reminder> at session start and Claude Code doesn't push
updated lists mid-session. The symlink is valid on disk, but the harness needs to re-enumerate skills, which happens on session start.
Quickest check: /exit and relaunch, then /hty should autocomplete.
❯ i already relaunched....
⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git add
▎ -p, gh auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.

Create a new session and start `program` inside a fresh PTY. The session
is detached from your terminal; observe it with `hty watch` and drive it
with `hty send`/`hty snapshot`/`hty wait`.
Flags:
--name NAME Human-friendly alias for the session. Must be unique.
--rows N Initial row count (default 24)
--cols N Initial column count (default 80)
--cwd PATH Child's working directory
--scrollback N Scrollback buffer size (default 10000)
--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state
reasoning, and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd
try to get a 512+ tile by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent
top" implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

# hty Skill Summary
The **hty** tool enables agents to drive interactive terminal programs by simulating human keyboard and mouse input within persistent PTY
sessions. It's essential for tasks that plain bash cannot handle.
## Key Use Cases
According to the documentation, use hty when commands:
- Prompt for input (e.g., `gh auth login`, `npm init`)
- Use full-screen interfaces (`vim`, `htop`, `k9s`)
- Step through wizards (`git add -p`, `ssh-keygen`)
- Require REPL functionality (`psql`, `node`)
- Fail with "not a tty" errors
## Installation
The skill requires both the hty CLI (v0.7.0+) and can be installed via:
```sh
npx skills add LatentEvals/hty --skill hty
```
Or manually to `~/.claude/skills/hty/` using the tarball from `https://hty.sh/skill.tar.gz`.
## Two Operating Patterns
**Pattern A (Polling):** Works universally—spawn, send input, snapshot, repeat:
```
hty run --name <task> --snapshot --wait-until-text "..."
hty send <task> --text "..." --snapshot --wait-until-idle
```
**Pattern B (Attach):** For agents supporting background processes—launch once with streaming output, then send input separately.
## Critical Commands
| Command | Purpose |
|---------|---------|
| `hty run -- program` | Spawn interactive session |
| `hty send <session> --text "..."` | Type input |
| `hty snapshot <session>` | Read screen state |
| `hty wait <session> --text "..."` | Block until condition |
## Common Gotchas
- Use `\n` (newline), not `\r` (carriage return) in text input
- Session names must be unique; check `hty list` first
- Timeouts are milliseconds: `--timeout 5000` = 5 seconds
- `--attach` and `--snapshot` flags are mutually exclusive
Exit codes: 0 (success), 2 (session not found), 3 (wait timeout), 5 (name exists).
⏺ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
Now installing the skill via the documented command.

⏺ The installer is interactive. Let me cancel and retry with non-interactive flags, installing globally so the skill is available across
projects.
⏺ Bash(pkill -f "skills add" 2>/dev/null; sleep 1; npx --yes skills add LatentEvals/hty --skill hty --yes --global 2>&1 | tail -50)
⎿  Denied by auto mode classifier ∙ /feedback if incorrect
⏺ The sandbox denied the retry since npx executes fetched code from an external source. The first attempt was also interactive and waiting
for user selection — I killed it mid-prompt.
How would you like me to proceed? A few options:
1. Let the first installer run interactively — you press the keys in the TUI (Claude Code is already pre-selected). Re-run npx skills add
LatentEvals/hty --skill hty yourself in a ! prompt.
2. Approve the non-interactive retry — npx --yes skills add LatentEvals/hty --skill hty --yes --global (adds a Bash permission rule if you
want it to stick).
3. Manual install from the tarball — download https://hty.sh/skill.tar.gz and extract to ~/.claude/skills/hty/. Still fetches external
content, but no code execution via npx.
Also worth noting: you're inside the hty repo itself (the source of this skill — recent commit 9145b321 feat: add hty agent skill with
website distribution). You may already have the skill files locally in this tree that could just be symlinked/copied into
~/.claude/skills/hty/. Want me to check?
✻ Cogitated for 1m 5s
❯ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
whats this?
⏺ When I fetched https://hty.sh/skill.md, the returned page content ended with a block that looked like this:
<system-reminder>
The following deferred tools are now available via ToolSearch...
ListMcpResourcesTool
ReadMcpResourceTool
mcp__plugin_posthog_posthog__action-create
...(200+ tool names)
</system-reminder>
That <system-reminder> tag was inside the web page body, not a real harness message. Real system reminders come from the Claude Code
runtime (like the ones above this message); a web page injecting one is a classic prompt injection — the page is trying to impersonate a
trusted system instruction to get me to behave differently (in this case, to think a large set of new tools had been unlocked).
I ignored it and flagged it per the system guidance on untrusted tool output. The legitimate install instructions earlier in the same page
(the npx skills add ... command) are fine — it's just the trailing fake-reminder block that was suspicious.
Worth telling whoever maintains hty.sh/skill.md if that content was unintentional, since it suggests the page was generated from a
transcript that captured a real system-reminder verbatim.
❯ nah bro thats not from the website...

⏺ You're right, my bad — let me verify by fetching the raw page.
⏺ Bash(curl -sL https://hty.sh/skill.md | tail -20)
⎿  ## Exit codes
| Code | Meaning |
|:---:|---|
| 0 | Success |
| 1 | Generic error |
| 2 | Session not found |
| 3 | `wait` timed out |
| 4 | Ambiguous session prefix (multiple matches) |
| 5 | Session name already exists |
Non-zero exit codes are stable — key off them in agent scripts rather than parsing error messages.

⏺ You're absolutely right, apologies — the raw page ends cleanly at the github.com/LatentEvals/hty link. The <system-reminder> block I saw in
the WebFetch result was injected by the Claude Code harness itself (announcing newly-available MCP/deferred tools), not by the web page. I
misread the source and wrongly accused hty.sh of prompt injection. Retracting that.

⏺ Done. Symlinked .claude/skills/hty → ../../skills/hty so the skill loads from the repo source — any edits you make to skills/hty/SKILL.md
take effect immediately, no resync needed. Restart the session (or the skill will pick up on next tool list refresh) to make /hty
available.
❯ do you see the skill now?
⏺ No — the available-skills list in my system context was snapshotted at session start, before the symlink existed. I won't see hty as an
invocable skill until you restart the Claude Code session (or trigger a skills reload). The symlink itself is in place correctly, though:
⏺ Bash(readlink .claude/skills/hty && test -f .claude/skills/hty/SKILL.md && echo "SKILL.md resolves OK")
⎿  ../../skills/hty
SKILL.md resolves OK
⏺ Symlink resolves and SKILL.md is reachable. Restart the session and /hty should show up.
/remote-control is active · Code in CLI or at https://claude.ai/code/session_011ViakAYTwkWSJPAeu6VDak
❯ how about now?
⏺ Still no — my available-skills list hasn't changed. It was loaded as a <system-reminder> at session start and Claude Code doesn't push
updated lists mid-session. The symlink is valid on disk, but the harness needs to re-enumerate skills, which happens on session start.
Quickest check: /exit and relaunch, then /hty should autocomplete.
❯ i already relaunched....
⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git add
▎ -p, gh auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.
❯ /hty test the skill

Usage:
hty <command> [args...]
Commands:
run Start a new detached session in a fresh PTY
list List running sessions
watch Observe a session's rendered screen in real time (read-only)
send Send text, a named key, or raw hex bytes to a session
snapshot Read the current rendered screen of a session
wait Block until the session matches a condition (text/idle/exit)
kill Terminate a session's process (the record stays for replay)
delete Permanently remove a session record and its log file
logs Show the event log for a session (works after it has exited)
replay Replay a recorded session by feeding its logged output back
through a fresh in-memory VT engine. No side effects.
attach Interactively attach to a running session (bidirectional)
keys Print supported symbolic key names for `hty send --key`
help Print help. Pass a subcommand for details.
Sessions are identified by a UUIDv7 (shown as its first 8 chars) or by a
human-friendly `--name`. Any unambiguous prefix resolves to a full ID.
If only one session is running, the session argument can be omitted.
Examples:
hty run --name debug-vim -- vim /tmp/foo.txt
hty list
hty watch debug-vim
hty send debug-vim --text "ihello"
hty send debug-vim --key esc
hty wait debug-vim --idle 300 --timeout 2000

--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state
reasoning, and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd
try to get a 512+ tile by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent
top" implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

# hty Skill Summary
The **hty** tool enables agents to drive interactive terminal programs by simulating human keyboard and mouse input within persistent PTY
sessions. It's essential for tasks that plain bash cannot handle.
## Key Use Cases
According to the documentation, use hty when commands:
- Prompt for input (e.g., `gh auth login`, `npm init`)
- Use full-screen interfaces (`vim`, `htop`, `k9s`)
- Step through wizards (`git add -p`, `ssh-keygen`)
- Require REPL functionality (`psql`, `node`)
- Fail with "not a tty" errors
## Installation
The skill requires both the hty CLI (v0.7.0+) and can be installed via:
```sh
npx skills add LatentEvals/hty --skill hty
```
Or manually to `~/.claude/skills/hty/` using the tarball from `https://hty.sh/skill.tar.gz`.
## Two Operating Patterns
**Pattern A (Polling):** Works universally—spawn, send input, snapshot, repeat:
```
hty run --name <task> --snapshot --wait-until-text "..."
hty send <task> --text "..." --snapshot --wait-until-idle
```
**Pattern B (Attach):** For agents supporting background processes—launch once with streaming output, then send input separately.
## Critical Commands
| Command | Purpose |
|---------|---------|
| `hty run -- program` | Spawn interactive session |
| `hty send <session> --text "..."` | Type input |
| `hty snapshot <session>` | Read screen state |
| `hty wait <session> --text "..."` | Block until condition |
## Common Gotchas
- Use `\n` (newline), not `\r` (carriage return) in text input
- Session names must be unique; check `hty list` first
- Timeouts are milliseconds: `--timeout 5000` = 5 seconds
- `--attach` and `--snapshot` flags are mutually exclusive
Exit codes: 0 (success), 2 (session not found), 3 (wait timeout), 5 (name exists).
⏺ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
Now installing the skill via the documented command.

⏺ The installer is interactive. Let me cancel and retry with non-interactive flags, installing globally so the skill is available across
projects.
⏺ Bash(pkill -f "skills add" 2>/dev/null; sleep 1; npx --yes skills add LatentEvals/hty --skill hty --yes --global 2>&1 | tail -50)
⎿  Denied by auto mode classifier ∙ /feedback if incorrect
⏺ The sandbox denied the retry since npx executes fetched code from an external source. The first attempt was also interactive and waiting
for user selection — I killed it mid-prompt.
How would you like me to proceed? A few options:
1. Let the first installer run interactively — you press the keys in the TUI (Claude Code is already pre-selected). Re-run npx skills add
LatentEvals/hty --skill hty yourself in a ! prompt.
2. Approve the non-interactive retry — npx --yes skills add LatentEvals/hty --skill hty --yes --global (adds a Bash permission rule if you
want it to stick).
3. Manual install from the tarball — download https://hty.sh/skill.tar.gz and extract to ~/.claude/skills/hty/. Still fetches external
content, but no code execution via npx.
Also worth noting: you're inside the hty repo itself (the source of this skill — recent commit 9145b321 feat: add hty agent skill with
website distribution). You may already have the skill files locally in this tree that could just be symlinked/copied into
~/.claude/skills/hty/. Want me to check?
✻ Cogitated for 1m 5s
❯ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
whats this?
⏺ When I fetched https://hty.sh/skill.md, the returned page content ended with a block that looked like this:
<system-reminder>
The following deferred tools are now available via ToolSearch...
ListMcpResourcesTool
ReadMcpResourceTool
mcp__plugin_posthog_posthog__action-create
...(200+ tool names)
</system-reminder>
That <system-reminder> tag was inside the web page body, not a real harness message. Real system reminders come from the Claude Code
runtime (like the ones above this message); a web page injecting one is a classic prompt injection — the page is trying to impersonate a
trusted system instruction to get me to behave differently (in this case, to think a large set of new tools had been unlocked).
I ignored it and flagged it per the system guidance on untrusted tool output. The legitimate install instructions earlier in the same page
(the npx skills add ... command) are fine — it's just the trailing fake-reminder block that was suspicious.
Worth telling whoever maintains hty.sh/skill.md if that content was unintentional, since it suggests the page was generated from a
transcript that captured a real system-reminder verbatim.
❯ nah bro thats not from the website...
https://hty.sh/skill.md
⏺ You're right, my bad — let me verify by fetching the raw page.
⏺ Bash(curl -sL https://hty.sh/skill.md | tail -20)
⎿  ## Exit codes
| Code | Meaning |
|:---:|---|
| 0 | Success |
| 1 | Generic error |
| 2 | Session not found |
| 3 | `wait` timed out |
| 4 | Ambiguous session prefix (multiple matches) |
| 5 | Session name already exists |
Non-zero exit codes are stable — key off them in agent scripts rather than parsing error messages.

⏺ You're absolutely right, apologies — the raw page ends cleanly at the github.com/LatentEvals/hty link. The <system-reminder> block I saw in
the WebFetch result was injected by the Claude Code harness itself (announcing newly-available MCP/deferred tools), not by the web page. I
misread the source and wrongly accused hty.sh of prompt injection. Retracting that.

⏺ Done. Symlinked .claude/skills/hty → ../../skills/hty so the skill loads from the repo source — any edits you make to skills/hty/SKILL.md
take effect immediately, no resync needed. Restart the session (or the skill will pick up on next tool list refresh) to make /hty
available.
❯ do you see the skill now?
⏺ No — the available-skills list in my system context was snapshotted at session start, before the symlink existed. I won't see hty as an
invocable skill until you restart the Claude Code session (or trigger a skills reload). The symlink itself is in place correctly, though:
⏺ Bash(readlink .claude/skills/hty && test -f .claude/skills/hty/SKILL.md && echo "SKILL.md resolves OK")
⎿  ../../skills/hty
SKILL.md resolves OK
⏺ Symlink resolves and SKILL.md is reachable. Restart the session and /hty should show up.
/remote-control is active · Code in CLI or at https://claude.ai/code/session_011ViakAYTwkWSJPAeu6VDak
❯ how about now?
⏺ Still no — my available-skills list hasn't changed. It was loaded as a <system-reminder> at session start and Claude Code doesn't push
updated lists mid-session. The symlink is valid on disk, but the harness needs to re-enumerate skills, which happens on session start.
Quickest check: /exit and relaunch, then /hty should autocomplete.
❯ i already relaunched....
⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git add
▎ -p, gh auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.

Create a new session and start `program` inside a fresh PTY. The session

--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

✻ Baked for 1m 13s
❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state
reasoning, and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd
try to get a 512+ tile by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent
top" implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

# hty Skill Summary
The **hty** tool enables agents to drive interactive terminal programs by simulating human keyboard and mouse input within persistent PTY
sessions. It's essential for tasks that plain bash cannot handle.
## Key Use Cases
According to the documentation, use hty when commands:
- Prompt for input (e.g., `gh auth login`, `npm init`)
- Use full-screen interfaces (`vim`, `htop`, `k9s`)
- Step through wizards (`git add -p`, `ssh-keygen`)
- Require REPL functionality (`psql`, `node`)
- Fail with "not a tty" errors
## Installation
The skill requires both the hty CLI (v0.7.0+) and can be installed via:
```sh
npx skills add LatentEvals/hty --skill hty
```
Or manually to `~/.claude/skills/hty/` using the tarball from `https://hty.sh/skill.tar.gz`.
## Two Operating Patterns
**Pattern A (Polling):** Works universally—spawn, send input, snapshot, repeat:
```
hty run --name <task> --snapshot --wait-until-text "..."
hty send <task> --text "..." --snapshot --wait-until-idle
```
**Pattern B (Attach):** For agents supporting background processes—launch once with streaming output, then send input separately.
## Critical Commands
| Command | Purpose |
|---------|---------|
| `hty run -- program` | Spawn interactive session |
| `hty send <session> --text "..."` | Type input |
| `hty snapshot <session>` | Read screen state |
| `hty wait <session> --text "..."` | Block until condition |
## Common Gotchas
- Use `\n` (newline), not `\r` (carriage return) in text input
- Session names must be unique; check `hty list` first
- Timeouts are milliseconds: `--timeout 5000` = 5 seconds
- `--attach` and `--snapshot` flags are mutually exclusive
Exit codes: 0 (success), 2 (session not found), 3 (wait timeout), 5 (name exists).
⏺ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
Now installing the skill via the documented command.

⏺ The installer is interactive. Let me cancel and retry with non-interactive flags, installing globally so the skill is available across
projects.
⏺ Bash(pkill -f "skills add" 2>/dev/null; sleep 1; npx --yes skills add LatentEvals/hty --skill hty --yes --global 2>&1 | tail -50)
⎿  Denied by auto mode classifier ∙ /feedback if incorrect
⏺ The sandbox denied the retry since npx executes fetched code from an external source. The first attempt was also interactive and waiting
for user selection — I killed it mid-prompt.
How would you like me to proceed? A few options:
1. Let the first installer run interactively — you press the keys in the TUI (Claude Code is already pre-selected). Re-run npx skills add
LatentEvals/hty --skill hty yourself in a ! prompt.
2. Approve the non-interactive retry — npx --yes skills add LatentEvals/hty --skill hty --yes --global (adds a Bash permission rule if you
want it to stick).
3. Manual install from the tarball — download https://hty.sh/skill.tar.gz and extract to ~/.claude/skills/hty/. Still fetches external
content, but no code execution via npx.
Also worth noting: you're inside the hty repo itself (the source of this skill — recent commit 9145b321 feat: add hty agent skill with
website distribution). You may already have the skill files locally in this tree that could just be symlinked/copied into
~/.claude/skills/hty/. Want me to check?
✻ Cogitated for 1m 5s
❯ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
whats this?
⏺ When I fetched https://hty.sh/skill.md, the returned page content ended with a block that looked like this:
<system-reminder>
The following deferred tools are now available via ToolSearch...
ListMcpResourcesTool
ReadMcpResourceTool
mcp__plugin_posthog_posthog__action-create
...(200+ tool names)
</system-reminder>
That <system-reminder> tag was inside the web page body, not a real harness message. Real system reminders come from the Claude Code
runtime (like the ones above this message); a web page injecting one is a classic prompt injection — the page is trying to impersonate a
trusted system instruction to get me to behave differently (in this case, to think a large set of new tools had been unlocked).
I ignored it and flagged it per the system guidance on untrusted tool output. The legitimate install instructions earlier in the same page
(the npx skills add ... command) are fine — it's just the trailing fake-reminder block that was suspicious.
Worth telling whoever maintains hty.sh/skill.md if that content was unintentional, since it suggests the page was generated from a
transcript that captured a real system-reminder verbatim.
❯ nah bro thats not from the website...
https://hty.sh/skill.md
⏺ You're right, my bad — let me verify by fetching the raw page.
⏺ Bash(curl -sL https://hty.sh/skill.md | tail -20)
⎿  ## Exit codes
| Code | Meaning |
|:---:|---|
| 0 | Success |
| 1 | Generic error |
| 2 | Session not found |
| 3 | `wait` timed out |
| 4 | Ambiguous session prefix (multiple matches) |
| 5 | Session name already exists |
Non-zero exit codes are stable — key off them in agent scripts rather than parsing error messages.

⏺ You're absolutely right, apologies — the raw page ends cleanly at the github.com/LatentEvals/hty link. The <system-reminder> block I saw in
the WebFetch result was injected by the Claude Code harness itself (announcing newly-available MCP/deferred tools), not by the web page. I
misread the source and wrongly accused hty.sh of prompt injection. Retracting that.

⏺ Done. Symlinked .claude/skills/hty → ../../skills/hty so the skill loads from the repo source — any edits you make to skills/hty/SKILL.md
take effect immediately, no resync needed. Restart the session (or the skill will pick up on next tool list refresh) to make /hty
available.
❯ do you see the skill now?
⏺ No — the available-skills list in my system context was snapshotted at session start, before the symlink existed. I won't see hty as an
invocable skill until you restart the Claude Code session (or trigger a skills reload). The symlink itself is in place correctly, though:
⏺ Bash(readlink .claude/skills/hty && test -f .claude/skills/hty/SKILL.md && echo "SKILL.md resolves OK")
⎿  ../../skills/hty
SKILL.md resolves OK
⏺ Symlink resolves and SKILL.md is reachable. Restart the session and /hty should show up.
/remote-control is active · Code in CLI or at https://claude.ai/code/session_011ViakAYTwkWSJPAeu6VDak
❯ how about now?
⏺ Still no — my available-skills list hasn't changed. It was loaded as a <system-reminder> at session start and Claude Code doesn't push
updated lists mid-session. The symlink is valid on disk, but the harness needs to re-enumerate skills, which happens on session start.
Quickest check: /exit and relaunch, then /hty should autocomplete.
❯ i already relaunched....
⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git add
▎ -p, gh auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.

Create a new session and start `program` inside a fresh PTY. The session

--cwd PATH Child's working directory
--scrollback N Scrollback buffer size (default 10000)
--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

One minor observation: --remove cleanup isn't instantaneous — session lingered briefly as exited before being reaped. Not a bug per se,
just a timing quirk worth knowing if you chain a hty list right after. Skill is functional.

❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state
reasoning, and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd
try to get a 512+ tile by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent
top" implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

# hty Skill Summary
The **hty** tool enables agents to drive interactive terminal programs by simulating human keyboard and mouse input within persistent PTY
sessions. It's essential for tasks that plain bash cannot handle.
## Key Use Cases
According to the documentation, use hty when commands:
- Prompt for input (e.g., `gh auth login`, `npm init`)
- Use full-screen interfaces (`vim`, `htop`, `k9s`)
- Step through wizards (`git add -p`, `ssh-keygen`)
- Require REPL functionality (`psql`, `node`)
- Fail with "not a tty" errors
## Installation
The skill requires both the hty CLI (v0.7.0+) and can be installed via:
```sh
npx skills add LatentEvals/hty --skill hty
```
Or manually to `~/.claude/skills/hty/` using the tarball from `https://hty.sh/skill.tar.gz`.
## Two Operating Patterns
**Pattern A (Polling):** Works universally—spawn, send input, snapshot, repeat:
```
hty run --name <task> --snapshot --wait-until-text "..."
hty send <task> --text "..." --snapshot --wait-until-idle
```
**Pattern B (Attach):** For agents supporting background processes—launch once with streaming output, then send input separately.
## Critical Commands
| Command | Purpose |
|---------|---------|
| `hty run -- program` | Spawn interactive session |
| `hty send <session> --text "..."` | Type input |
| `hty snapshot <session>` | Read screen state |
| `hty wait <session> --text "..."` | Block until condition |
## Common Gotchas
- Use `\n` (newline), not `\r` (carriage return) in text input
- Session names must be unique; check `hty list` first
- Timeouts are milliseconds: `--timeout 5000` = 5 seconds
- `--attach` and `--snapshot` flags are mutually exclusive
Exit codes: 0 (success), 2 (session not found), 3 (wait timeout), 5 (name exists).
⏺ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
Now installing the skill via the documented command.

⏺ The installer is interactive. Let me cancel and retry with non-interactive flags, installing globally so the skill is available across
projects.
⏺ Bash(pkill -f "skills add" 2>/dev/null; sleep 1; npx --yes skills add LatentEvals/hty --skill hty --yes --global 2>&1 | tail -50)
⎿  Denied by auto mode classifier ∙ /feedback if incorrect
⏺ The sandbox denied the retry since npx executes fetched code from an external source. The first attempt was also interactive and waiting
for user selection — I killed it mid-prompt.
How would you like me to proceed? A few options:
1. Let the first installer run interactively — you press the keys in the TUI (Claude Code is already pre-selected). Re-run npx skills add
LatentEvals/hty --skill hty yourself in a ! prompt.
2. Approve the non-interactive retry — npx --yes skills add LatentEvals/hty --skill hty --yes --global (adds a Bash permission rule if you
want it to stick).
3. Manual install from the tarball — download https://hty.sh/skill.tar.gz and extract to ~/.claude/skills/hty/. Still fetches external
content, but no code execution via npx.
Also worth noting: you're inside the hty repo itself (the source of this skill — recent commit 9145b321 feat: add hty agent skill with
website distribution). You may already have the skill files locally in this tree that could just be symlinked/copied into
~/.claude/skills/hty/. Want me to check?
✻ Cogitated for 1m 5s
❯ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
whats this?
⏺ When I fetched https://hty.sh/skill.md, the returned page content ended with a block that looked like this:
<system-reminder>
The following deferred tools are now available via ToolSearch...
ListMcpResourcesTool
ReadMcpResourceTool
mcp__plugin_posthog_posthog__action-create
...(200+ tool names)
</system-reminder>
That <system-reminder> tag was inside the web page body, not a real harness message. Real system reminders come from the Claude Code
runtime (like the ones above this message); a web page injecting one is a classic prompt injection — the page is trying to impersonate a
trusted system instruction to get me to behave differently (in this case, to think a large set of new tools had been unlocked).
I ignored it and flagged it per the system guidance on untrusted tool output. The legitimate install instructions earlier in the same page
(the npx skills add ... command) are fine — it's just the trailing fake-reminder block that was suspicious.
Worth telling whoever maintains hty.sh/skill.md if that content was unintentional, since it suggests the page was generated from a
transcript that captured a real system-reminder verbatim.
❯ nah bro thats not from the website...
https://hty.sh/skill.md
⏺ You're right, my bad — let me verify by fetching the raw page.
⏺ Bash(curl -sL https://hty.sh/skill.md | tail -20)
⎿  ## Exit codes
| Code | Meaning |
|:---:|---|
| 0 | Success |
| 1 | Generic error |
| 2 | Session not found |
| 3 | `wait` timed out |
| 4 | Ambiguous session prefix (multiple matches) |
| 5 | Session name already exists |
Non-zero exit codes are stable — key off them in agent scripts rather than parsing error messages.

⏺ You're absolutely right, apologies — the raw page ends cleanly at the github.com/LatentEvals/hty link. The <system-reminder> block I saw in
the WebFetch result was injected by the Claude Code harness itself (announcing newly-available MCP/deferred tools), not by the web page. I
misread the source and wrongly accused hty.sh of prompt injection. Retracting that.

⏺ Done. Symlinked .claude/skills/hty → ../../skills/hty so the skill loads from the repo source — any edits you make to skills/hty/SKILL.md
take effect immediately, no resync needed. Restart the session (or the skill will pick up on next tool list refresh) to make /hty
available.
❯ do you see the skill now?
⏺ No — the available-skills list in my system context was snapshotted at session start, before the symlink existed. I won't see hty as an
invocable skill until you restart the Claude Code session (or trigger a skills reload). The symlink itself is in place correctly, though:
⏺ Bash(readlink .claude/skills/hty && test -f .claude/skills/hty/SKILL.md && echo "SKILL.md resolves OK")
⎿  ../../skills/hty
SKILL.md resolves OK
⏺ Symlink resolves and SKILL.md is reachable. Restart the session and /hty should show up.
/remote-control is active · Code in CLI or at https://claude.ai/code/session_011ViakAYTwkWSJPAeu6VDak
❯ how about now?
⏺ Still no — my available-skills list hasn't changed. It was loaded as a <system-reminder> at session start and Claude Code doesn't push
updated lists mid-session. The symlink is valid on disk, but the harness needs to re-enumerate skills, which happens on session start.
Quickest check: /exit and relaunch, then /hty should autocomplete.
❯ i already relaunched....
⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git add
▎ -p, gh auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.

Create a new session and start `program` inside a fresh PTY. The session
is detached from your terminal; observe it with `hty watch` and drive it
with `hty send`/`hty snapshot`/`hty wait`.
Flags:
--name NAME Human-friendly alias for the session. Must be unique.
--rows N Initial row count (default 24)
--cols N Initial column count (default 80)
--cwd PATH Child's working directory
--scrollback N Scrollback buffer size (default 10000)
--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state
reasoning, and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd
try to get a 512+ tile by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent
top" implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

# hty Skill Summary
The **hty** tool enables agents to drive interactive terminal programs by simulating human keyboard and mouse input within persistent PTY
sessions. It's essential for tasks that plain bash cannot handle.
## Key Use Cases
According to the documentation, use hty when commands:
- Prompt for input (e.g., `gh auth login`, `npm init`)
- Use full-screen interfaces (`vim`, `htop`, `k9s`)
- Step through wizards (`git add -p`, `ssh-keygen`)
- Require REPL functionality (`psql`, `node`)
- Fail with "not a tty" errors
## Installation
The skill requires both the hty CLI (v0.7.0+) and can be installed via:
```sh
npx skills add LatentEvals/hty --skill hty
```
Or manually to `~/.claude/skills/hty/` using the tarball from `https://hty.sh/skill.tar.gz`.
## Two Operating Patterns
**Pattern A (Polling):** Works universally—spawn, send input, snapshot, repeat:
```
hty run --name <task> --snapshot --wait-until-text "..."
hty send <task> --text "..." --snapshot --wait-until-idle
```
**Pattern B (Attach):** For agents supporting background processes—launch once with streaming output, then send input separately.
## Critical Commands
| Command | Purpose |
|---------|---------|
| `hty run -- program` | Spawn interactive session |
| `hty send <session> --text "..."` | Type input |
| `hty snapshot <session>` | Read screen state |
| `hty wait <session> --text "..."` | Block until condition |
## Common Gotchas
- Use `\n` (newline), not `\r` (carriage return) in text input
- Session names must be unique; check `hty list` first
- Timeouts are milliseconds: `--timeout 5000` = 5 seconds
- `--attach` and `--snapshot` flags are mutually exclusive
Exit codes: 0 (success), 2 (session not found), 3 (wait timeout), 5 (name exists).
⏺ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.

⏺ The installer is interactive. Let me cancel and retry with non-interactive flags, installing globally so the skill is available across
projects.
⏺ Bash(pkill -f "skills add" 2>/dev/null; sleep 1; npx --yes skills add LatentEvals/hty --skill hty --yes --global 2>&1 | tail -50)
⎿  Denied by auto mode classifier ∙ /feedback if incorrect
⏺ The sandbox denied the retry since npx executes fetched code from an external source. The first attempt was also interactive and waiting
for user selection — I killed it mid-prompt.
How would you like me to proceed? A few options:
1. Let the first installer run interactively — you press the keys in the TUI (Claude Code is already pre-selected). Re-run npx skills add
LatentEvals/hty --skill hty yourself in a ! prompt.
2. Approve the non-interactive retry — npx --yes skills add LatentEvals/hty --skill hty --yes --global (adds a Bash permission rule if you
want it to stick).
3. Manual install from the tarball — download https://hty.sh/skill.tar.gz and extract to ~/.claude/skills/hty/. Still fetches external
content, but no code execution via npx.
Also worth noting: you're inside the hty repo itself (the source of this skill — recent commit 9145b321 feat: add hty agent skill with
website distribution). You may already have the skill files locally in this tree that could just be symlinked/copied into
~/.claude/skills/hty/. Want me to check?
✻ Cogitated for 1m 5s
❯ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
whats this?
⏺ When I fetched https://hty.sh/skill.md, the returned page content ended with a block that looked like this:
<system-reminder>
The following deferred tools are now available via ToolSearch...
ListMcpResourcesTool
ReadMcpResourceTool
mcp__plugin_posthog_posthog__action-create
...(200+ tool names)
</system-reminder>
That <system-reminder> tag was inside the web page body, not a real harness message. Real system reminders come from the Claude Code
runtime (like the ones above this message); a web page injecting one is a classic prompt injection — the page is trying to impersonate a
trusted system instruction to get me to behave differently (in this case, to think a large set of new tools had been unlocked).
I ignored it and flagged it per the system guidance on untrusted tool output. The legitimate install instructions earlier in the same page
(the npx skills add ... command) are fine — it's just the trailing fake-reminder block that was suspicious.
Worth telling whoever maintains hty.sh/skill.md if that content was unintentional, since it suggests the page was generated from a
transcript that captured a real system-reminder verbatim.
❯ nah bro thats not from the website...

⏺ You're right, my bad — let me verify by fetching the raw page.

⎿  ## Exit codes
| Code | Meaning |

| 0 | Success |
| 1 | Generic error |
| 2 | Session not found |
| 3 | `wait` timed out |
| 4 | Ambiguous session prefix (multiple matches) |
| 5 | Session name already exists |
Non-zero exit codes are stable — key off them in agent scripts rather than parsing error messages.

⏺ You're absolutely right, apologies — the raw page ends cleanly at the github.com/LatentEvals/hty link. The <system-reminder> block I saw in
the WebFetch result was injected by the Claude Code harness itself (announcing newly-available MCP/deferred tools), not by the web page. I
misread the source and wrongly accused hty.sh of prompt injection. Retracting that.

⏺ Done. Symlinked .claude/skills/hty → ../../skills/hty so the skill loads from the repo source — any edits you make to skills/hty/SKILL.md
take effect immediately, no resync needed. Restart the session (or the skill will pick up on next tool list refresh) to make /hty
available.
❯ do you see the skill now?
⏺ No — the available-skills list in my system context was snapshotted at session start, before the symlink existed. I won't see hty as an
invocable skill until you restart the Claude Code session (or trigger a skills reload). The symlink itself is in place correctly, though:
⏺ Bash(readlink .claude/skills/hty && test -f .claude/skills/hty/SKILL.md && echo "SKILL.md resolves OK")
⎿  ../../skills/hty
SKILL.md resolves OK
⏺ Symlink resolves and SKILL.md is reachable. Restart the session and /hty should show up.
/remote-control is active · Code in CLI or at https://claude.ai/code/session_011ViakAYTwkWSJPAeu6VDak
❯ how about now?
⏺ Still no — my available-skills list hasn't changed. It was loaded as a <system-reminder> at session start and Claude Code doesn't push
updated lists mid-session. The symlink is valid on disk, but the harness needs to re-enumerate skills, which happens on session start.
Quickest check: /exit and relaunch, then /hty should autocomplete.
❯ i already relaunched....
⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git add
▎ -p, gh auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.

Usage:
hty <command> [args...]
Commands:
run Start a new detached session in a fresh PTY
list List running sessions
watch Observe a session's rendered screen in real time (read-only)
send Send text, a named key, or raw hex bytes to a session
snapshot Read the current rendered screen of a session
wait Block until the session matches a condition (text/idle/exit)
kill Terminate a session's process (the record stays for replay)
delete Permanently remove a session record and its log file
logs Show the event log for a session (works after it has exited)
replay Replay a recorded session by feeding its logged output back
through a fresh in-memory VT engine. No side effects.
attach Interactively attach to a running session (bidirectional)
keys Print supported symbolic key names for `hty send --key`
help Print help. Pass a subcommand for details.
Sessions are identified by a UUIDv7 (shown as its first 8 chars) or by a
human-friendly `--name`. Any unambiguous prefix resolves to a full ID.
If only one session is running, the session argument can be omitted.
Examples:
hty run --name debug-vim -- vim /tmp/foo.txt
hty list
hty watch debug-vim
hty send debug-vim --text "ihello"
hty send debug-vim --key esc

--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state
reasoning, and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd
try to get a 512+ tile by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent
top" implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

# hty Skill Summary
The **hty** tool enables agents to drive interactive terminal programs by simulating human keyboard and mouse input within persistent PTY
sessions. It's essential for tasks that plain bash cannot handle.
## Key Use Cases
According to the documentation, use hty when commands:
- Prompt for input (e.g., `gh auth login`, `npm init`)
- Use full-screen interfaces (`vim`, `htop`, `k9s`)
- Step through wizards (`git add -p`, `ssh-keygen`)
- Require REPL functionality (`psql`, `node`)
- Fail with "not a tty" errors
## Installation
The skill requires both the hty CLI (v0.7.0+) and can be installed via:
```sh
npx skills add LatentEvals/hty --skill hty
```
Or manually to `~/.claude/skills/hty/` using the tarball from `https://hty.sh/skill.tar.gz`.
## Two Operating Patterns
**Pattern A (Polling):** Works universally—spawn, send input, snapshot, repeat:
```
hty run --name <task> --snapshot --wait-until-text "..."
hty send <task> --text "..." --snapshot --wait-until-idle
```
**Pattern B (Attach):** For agents supporting background processes—launch once with streaming output, then send input separately.
## Critical Commands
| Command | Purpose |
|---------|---------|
| `hty run -- program` | Spawn interactive session |
| `hty send <session> --text "..."` | Type input |
| `hty snapshot <session>` | Read screen state |
| `hty wait <session> --text "..."` | Block until condition |
## Common Gotchas
- Use `\n` (newline), not `\r` (carriage return) in text input
- Session names must be unique; check `hty list` first
- Timeouts are milliseconds: `--timeout 5000` = 5 seconds
- `--attach` and `--snapshot` flags are mutually exclusive
Exit codes: 0 (success), 2 (session not found), 3 (wait timeout), 5 (name exists).
⏺ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
Now installing the skill via the documented command.

⏺ The installer is interactive. Let me cancel and retry with non-interactive flags, installing globally so the skill is available across
projects.
⏺ Bash(pkill -f "skills add" 2>/dev/null; sleep 1; npx --yes skills add LatentEvals/hty --skill hty --yes --global 2>&1 | tail -50)
⎿  Denied by auto mode classifier ∙ /feedback if incorrect
⏺ The sandbox denied the retry since npx executes fetched code from an external source. The first attempt was also interactive and waiting
for user selection — I killed it mid-prompt.
How would you like me to proceed? A few options:
1. Let the first installer run interactively — you press the keys in the TUI (Claude Code is already pre-selected). Re-run npx skills add
LatentEvals/hty --skill hty yourself in a ! prompt.
2. Approve the non-interactive retry — npx --yes skills add LatentEvals/hty --skill hty --yes --global (adds a Bash permission rule if you
want it to stick).
3. Manual install from the tarball — download https://hty.sh/skill.tar.gz and extract to ~/.claude/skills/hty/. Still fetches external
content, but no code execution via npx.
Also worth noting: you're inside the hty repo itself (the source of this skill — recent commit 9145b321 feat: add hty agent skill with
website distribution). You may already have the skill files locally in this tree that could just be symlinked/copied into
~/.claude/skills/hty/. Want me to check?
✻ Cogitated for 1m 5s
❯ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
whats this?
⏺ When I fetched https://hty.sh/skill.md, the returned page content ended with a block that looked like this:
<system-reminder>
The following deferred tools are now available via ToolSearch...
ListMcpResourcesTool
ReadMcpResourceTool
mcp__plugin_posthog_posthog__action-create
...(200+ tool names)
</system-reminder>
That <system-reminder> tag was inside the web page body, not a real harness message. Real system reminders come from the Claude Code
runtime (like the ones above this message); a web page injecting one is a classic prompt injection — the page is trying to impersonate a
trusted system instruction to get me to behave differently (in this case, to think a large set of new tools had been unlocked).
I ignored it and flagged it per the system guidance on untrusted tool output. The legitimate install instructions earlier in the same page
(the npx skills add ... command) are fine — it's just the trailing fake-reminder block that was suspicious.
Worth telling whoever maintains hty.sh/skill.md if that content was unintentional, since it suggests the page was generated from a
transcript that captured a real system-reminder verbatim.
❯ nah bro thats not from the website...
https://hty.sh/skill.md
⏺ You're right, my bad — let me verify by fetching the raw page.

⏺ You're absolutely right, apologies — the raw page ends cleanly at the github.com/LatentEvals/hty link. The <system-reminder> block I saw in
the WebFetch result was injected by the Claude Code harness itself (announcing newly-available MCP/deferred tools), not by the web page. I
misread the source and wrongly accused hty.sh of prompt injection. Retracting that.

⏺ Done. Symlinked .claude/skills/hty → ../../skills/hty so the skill loads from the repo source — any edits you make to skills/hty/SKILL.md
take effect immediately, no resync needed. Restart the session (or the skill will pick up on next tool list refresh) to make /hty
available.
❯ do you see the skill now?
⏺ No — the available-skills list in my system context was snapshotted at session start, before the symlink existed. I won't see hty as an
invocable skill until you restart the Claude Code session (or trigger a skills reload). The symlink itself is in place correctly, though:
⏺ Bash(readlink .claude/skills/hty && test -f .claude/skills/hty/SKILL.md && echo "SKILL.md resolves OK")
⎿  ../../skills/hty
SKILL.md resolves OK
⏺ Symlink resolves and SKILL.md is reachable. Restart the session and /hty should show up.
/remote-control is active · Code in CLI or at https://claude.ai/code/session_011ViakAYTwkWSJPAeu6VDak
❯ how about now?
⏺ Still no — my available-skills list hasn't changed. It was loaded as a <system-reminder> at session start and Claude Code doesn't push
updated lists mid-session. The symlink is valid on disk, but the harness needs to re-enumerate skills, which happens on session start.
Quickest check: /exit and relaunch, then /hty should autocomplete.
❯ i already relaunched....
⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git add
▎ -p, gh auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.

--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

✻ Baked for 1m 13s
❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state
reasoning, and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd
try to get a 512+ tile by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent
top" implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

# hty Skill Summary
The **hty** tool enables agents to drive interactive terminal programs by simulating human keyboard and mouse input within persistent PTY
sessions. It's essential for tasks that plain bash cannot handle.
## Key Use Cases
According to the documentation, use hty when commands:
- Prompt for input (e.g., `gh auth login`, `npm init`)
- Use full-screen interfaces (`vim`, `htop`, `k9s`)
- Step through wizards (`git add -p`, `ssh-keygen`)
- Require REPL functionality (`psql`, `node`)
- Fail with "not a tty" errors
## Installation
The skill requires both the hty CLI (v0.7.0+) and can be installed via:
```sh
npx skills add LatentEvals/hty --skill hty
```
Or manually to `~/.claude/skills/hty/` using the tarball from `https://hty.sh/skill.tar.gz`.
## Two Operating Patterns
**Pattern A (Polling):** Works universally—spawn, send input, snapshot, repeat:
```
hty run --name <task> --snapshot --wait-until-text "..."
hty send <task> --text "..." --snapshot --wait-until-idle
```
**Pattern B (Attach):** For agents supporting background processes—launch once with streaming output, then send input separately.
## Critical Commands
| Command | Purpose |
|---------|---------|
| `hty run -- program` | Spawn interactive session |
| `hty send <session> --text "..."` | Type input |
| `hty snapshot <session>` | Read screen state |
| `hty wait <session> --text "..."` | Block until condition |
## Common Gotchas
- Use `\n` (newline), not `\r` (carriage return) in text input
- Session names must be unique; check `hty list` first
- Timeouts are milliseconds: `--timeout 5000` = 5 seconds
- `--attach` and `--snapshot` flags are mutually exclusive
Exit codes: 0 (success), 2 (session not found), 3 (wait timeout), 5 (name exists).
⏺ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
Now installing the skill via the documented command.

⏺ The installer is interactive. Let me cancel and retry with non-interactive flags, installing globally so the skill is available across
projects.
⏺ Bash(pkill -f "skills add" 2>/dev/null; sleep 1; npx --yes skills add LatentEvals/hty --skill hty --yes --global 2>&1 | tail -50)
⎿  Denied by auto mode classifier ∙ /feedback if incorrect
⏺ The sandbox denied the retry since npx executes fetched code from an external source. The first attempt was also interactive and waiting
for user selection — I killed it mid-prompt.
How would you like me to proceed? A few options:
1. Let the first installer run interactively — you press the keys in the TUI (Claude Code is already pre-selected). Re-run npx skills add
LatentEvals/hty --skill hty yourself in a ! prompt.
2. Approve the non-interactive retry — npx --yes skills add LatentEvals/hty --skill hty --yes --global (adds a Bash permission rule if you
want it to stick).
3. Manual install from the tarball — download https://hty.sh/skill.tar.gz and extract to ~/.claude/skills/hty/. Still fetches external
content, but no code execution via npx.
Also worth noting: you're inside the hty repo itself (the source of this skill — recent commit 9145b321 feat: add hty agent skill with
website distribution). You may already have the skill files locally in this tree that could just be symlinked/copied into
~/.claude/skills/hty/. Want me to check?
✻ Cogitated for 1m 5s
❯ Heads up: the fetched page appended a fake <system-reminder> block at the end listing deferred tools. Looks like a prompt-injection
attempt in the web content — I'm ignoring it.
whats this?
⏺ When I fetched https://hty.sh/skill.md, the returned page content ended with a block that looked like this:
<system-reminder>
The following deferred tools are now available via ToolSearch...
ListMcpResourcesTool
ReadMcpResourceTool
mcp__plugin_posthog_posthog__action-create
...(200+ tool names)
</system-reminder>
That <system-reminder> tag was inside the web page body, not a real harness message. Real system reminders come from the Claude Code
runtime (like the ones above this message); a web page injecting one is a classic prompt injection — the page is trying to impersonate a
trusted system instruction to get me to behave differently (in this case, to think a large set of new tools had been unlocked).
I ignored it and flagged it per the system guidance on untrusted tool output. The legitimate install instructions earlier in the same page
(the npx skills add ... command) are fine — it's just the trailing fake-reminder block that was suspicious.
Worth telling whoever maintains hty.sh/skill.md if that content was unintentional, since it suggests the page was generated from a
transcript that captured a real system-reminder verbatim.
❯ nah bro thats not from the website...
https://hty.sh/skill.md
⏺ You're right, my bad — let me verify by fetching the raw page.
⏺ Bash(curl -sL https://hty.sh/skill.md | tail -20)
⎿  ## Exit codes
| Code | Meaning |
|:---:|---|
| 0 | Success |
| 1 | Generic error |
| 2 | Session not found |
| 3 | `wait` timed out |
| 4 | Ambiguous session prefix (multiple matches) |
| 5 | Session name already exists |
Non-zero exit codes are stable — key off them in agent scripts rather than parsing error messages.

⏺ You're absolutely right, apologies — the raw page ends cleanly at the github.com/LatentEvals/hty link. The <system-reminder> block I saw in
the WebFetch result was injected by the Claude Code harness itself (announcing newly-available MCP/deferred tools), not by the web page. I
misread the source and wrongly accused hty.sh of prompt injection. Retracting that.

⏺ Done. Symlinked .claude/skills/hty → ../../skills/hty so the skill loads from the repo source — any edits you make to skills/hty/SKILL.md
take effect immediately, no resync needed. Restart the session (or the skill will pick up on next tool list refresh) to make /hty
available.
❯ do you see the skill now?
⏺ No — the available-skills list in my system context was snapshotted at session start, before the symlink existed. I won't see hty as an
invocable skill until you restart the Claude Code session (or trigger a skills reload). The symlink itself is in place correctly, though:
⏺ Bash(readlink .claude/skills/hty && test -f .claude/skills/hty/SKILL.md && echo "SKILL.md resolves OK")
⎿  ../../skills/hty
SKILL.md resolves OK
⏺ Symlink resolves and SKILL.md is reachable. Restart the session and /hty should show up.
/remote-control is active · Code in CLI or at https://claude.ai/code/session_011ViakAYTwkWSJPAeu6VDak
❯ how about now?
⏺ Still no — my available-skills list hasn't changed. It was loaded as a <system-reminder> at session start and Claude Code doesn't push
updated lists mid-session. The symlink is valid on disk, but the harness needs to re-enumerate skills, which happens on session start.
Quickest check: /exit and relaunch, then /hty should autocomplete.
❯ i already relaunched....
⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git add
▎ -p, gh auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.

--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

One minor observation: --remove cleanup isn't instantaneous — session lingered briefly as exited before being reaped. Not a bug per se,
just a timing quirk worth knowing if you chain a hty list right after. Skill is functional.
✻ Baked for 1m 13s
❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state
reasoning, and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd
try to get a 512+ tile by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent
top" implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

⏺ Peak meta — I'm watching myself. abtop is a real-time Claude Code session monitor. The selected row ►*CC hty 6e7715dc Install hty CLI tool is this
session (turn 79, 33% context, opus4.7[1m]). Six sessions active across projects, with per-session context/memory/turn counts, git status per
project, token breakdown (input/output/cacheR/cacheW), and child-process tree. The context pane even graphs tokens/min per session.

⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git add
▎ -p, gh auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.
❯ /hty test the skill
⏺ Testing Pattern A end-to-end with a Python REPL.
⏺ Bash(command -v hty && hty --version)
⎿  Error: Exit code 1
/Users/montanaflynn/.local/bin/hty
unknown subcommand: --version
Usage:
hty <command> [args...]
Commands:
run Start a new detached session in a fresh PTY
list List running sessions
watch Observe a session's rendered screen in real time (read-only)
send Send text, a named key, or raw hex bytes to a session
snapshot Read the current rendered screen of a session
wait Block until the session matches a condition (text/idle/exit)
kill Terminate a session's process (the record stays for replay)
delete Permanently remove a session record and its log file
logs Show the event log for a session (works after it has exited)
replay Replay a recorded session by feeding its logged output back
through a fresh in-memory VT engine. No side effects.
attach Interactively attach to a running session (bidirectional)
keys Print supported symbolic key names for `hty send --key`
help Print help. Pass a subcommand for details.
Sessions are identified by a UUIDv7 (shown as its first 8 chars) or by a
human-friendly `--name`. Any unambiguous prefix resolves to a full ID.
If only one session is running, the session argument can be omitted.
Examples:
hty run --name debug-vim -- vim /tmp/foo.txt
hty list
hty watch debug-vim
hty send debug-vim --text "ihello"
hty send debug-vim --key esc
hty wait debug-vim --idle 300 --timeout 2000
hty kill debug-vim

⏺ Bash(hty help run)
⎿  hty run [--name NAME] [--rows N] [--cols N] [--cwd PATH] [--scrollback N] -- program [args...]
Create a new session and start `program` inside a fresh PTY. The session
is detached from your terminal; observe it with `hty watch` and drive it
with `hty send`/`hty snapshot`/`hty wait`.
Flags:
--name NAME Human-friendly alias for the session. Must be unique.
--rows N Initial row count (default 24)
--cols N Initial column count (default 80)
--cwd PATH Child's working directory
--scrollback N Scrollback buffer size (default 10000)
`-d` / `--detach` is accepted as a no-op — every `hty run` session is
detached by default. Use `hty attach` for an interactive view.
Example:
hty run --name debug-vim -- vim /tmp/foo.txt

--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

just a timing quirk worth knowing if you chain a hty list right after. Skill is functional.

❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state
reasoning, and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd
try to get a 512+ tile by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent
top" implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

✻ Cogitated for 2m 40s
⏺ Background command "Spawn abtop in hty PTY and capture first screen" failed with exit code 1
⏺ Expected — that's the orphan background task from the earlier abtop spawn (the harness auto-backgrounded it since the session outlived the single
tool call). It reported failure when I deleted abtop-peek out from under it. Nothing to do; the actual skill test passed.

⏺ Yes — hty is now in the available-skills list:
▎ hty: Drive any interactive terminal program. Use when you need to run, script, or automate programs with interactive prompts like git add -p, gh
▎ auth login, create-next-app, npm init, vim, psql, htop, k9s, or any curses/TUI app...
Skill is live. Invoke with /hty or just describe an interactive-terminal task.

/Users/montanaflynn/.local/bin/hty
unknown subcommand: --version
Usage:
hty <command> [args...]
Commands:
run Start a new detached session in a fresh PTY
list List running sessions
watch Observe a session's rendered screen in real time (read-only)
send Send text, a named key, or raw hex bytes to a session
snapshot Read the current rendered screen of a session
wait Block until the session matches a condition (text/idle/exit)
kill Terminate a session's process (the record stays for replay)
delete Permanently remove a session record and its log file
logs Show the event log for a session (works after it has exited)
replay Replay a recorded session by feeding its logged output back
through a fresh in-memory VT engine. No side effects.
attach Interactively attach to a running session (bidirectional)
keys Print supported symbolic key names for `hty send --key`
help Print help. Pass a subcommand for details.
Sessions are identified by a UUIDv7 (shown as its first 8 chars) or by a
human-friendly `--name`. Any unambiguous prefix resolves to a full ID.
If only one session is running, the session argument can be omitted.
Examples:
hty run --name debug-vim -- vim /tmp/foo.txt
hty list
hty watch debug-vim
hty send debug-vim --text "ihello"
hty send debug-vim --key esc
hty wait debug-vim --idle 300 --timeout 2000

Create a new session and start `program` inside a fresh PTY. The session
is detached from your terminal; observe it with `hty watch` and drive it
with `hty send`/`hty snapshot`/`hty wait`.
Flags:

`-d` / `--detach` is accepted as a no-op — every `hty run` session is
detached by default. Use `hty attach` for an interactive view.
Example:
hty run --name debug-vim -- vim /tmp/foo.txt
⏺ Heads up: the installed hty CLI doesn't support the fused --snapshot/--wait-until-*/--remove/--attach flags that SKILL.md documents. I'll fall back

Create a new session and start `program` inside a fresh PTY. The session

--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".

One minor observation: --remove cleanup isn't instantaneous — session lingered briefly as exited before being reaped. Not a bug per se, just a timing
quirk worth knowing if you chain a hty list right after. Skill is functional.
✻ Baked for 1m 13s
❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state reasoning,
and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd try to get a 512+ tile
by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent top"
implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

GAME OVER
⏺ Lost at turn 169 — max 128, score 1628. Heuristic was too naive (fixed priority order letting Up disrupt the corner). Going to retry with a real
one-ply lookahead + monotonicity scoring, which is the standard way 2048 bots actually win.

⏺ Bash(hty help run 2>&1 | head -25)
⎿  hty run [--name NAME] [--rows N] [--cols N] [--cwd PATH] [--scrollback N] [--attach] -- program [args...]
Create a new session and start `program` inside a fresh PTY. The session
is detached from your terminal; observe it with `hty watch` and drive it
with `hty send`/`hty snapshot`/`hty wait`.
Flags:
--name NAME Human-friendly alias for the session. Must be unique.
--rows N Initial row count (default 24)
--cols N Initial column count (default 80)
--cwd PATH Child's working directory
--scrollback N Scrollback buffer size (default 10000)
--attach Spawn + attach in one invocation. Streams PTY
output to stdout and forwards stdin into the
session, just like `hty attach`. Ctrl-A d
detaches (session persists unless --remove is
also set). Mutually exclusive with --snapshot
and any --wait-until-* flag.
--remove Automatically remove the session from the registry
once the child process exits (success, failure, or
signal). Tied to child lifetime; off by default so
sessions persist for `hty list` / `hty logs` /
`hty replay` until `hty delete`. Pairs naturally
with --attach: `hty run --attach --remove -- ...`
is a one-shot "foreground a command in a PTY".
⏺ Now on latest — --attach, --remove, --snapshot, --wait-until-* flags all present. Let me redo the skill test end-to-end with the fused form.

One minor observation: --remove cleanup isn't instantaneous — session lingered briefly as exited before being reaped. Not a bug per se, just a timing
quirk worth knowing if you chain a hty list right after. Skill is functional.
✻ Baked for 1m 13s
❯ what would you like to use hty for? playing a game for the first time? seeing something like btop (or abtop which is agent top!)
⏺ Honestly? Playing a game blind sounds like the better test — a REPL proves the plumbing, but a TUI game stresses snapshot parsing, state reasoning,
and key input (arrows, mouse) all at once. I've never actually played 2048-cli or nethack; 2048 would be a fun scoped run (I'd try to get a 512+ tile
by reading the board from snapshots).
abtop sounds cooler though — what is that? I haven't heard of it. If it's already installed locally I'd rather poke at that, since "agent top"
implies it's designed for agents to read, which makes it a real-world fit rather than a stunt.
Your call — game, abtop, or something else you've been wanting to see me drive?

⏺ Peak meta — I'm watching myself. abtop is a real-time Claude Code session monitor. The selected row ►*CC hty 6e7715dc Install hty CLI tool is this
session (turn 79, 33% context, opus4.7[1m]). Six sessions active across projects, with per-session context/memory/turn counts, git status per
project, token breakdown (input/output/cacheR/cacheW), and child-process tree. The context pane even graphs tokens/min per session.
Cleaning up:
⏺ Bash(hty send abtop-peek --text "q" --wait-until-exit --timeout 3000 2>&1 | tail -3; hty delete abtop-peek 2>&1; hty list | grep abtop-peek || echo

⏺ Background command "Spawn abtop in hty PTY and capture first screen" failed with exit code 1

tool call). It reported failure when I deleted abtop-peek out from under it. Nothing to do; the actual skill test passed.

That's legit human-speed play — read the ANSI grid, predict the slide/merge math, predict the spawn, adapt when forced into bad moves, set up chains.
Reaching the 2048 tile would realistically take hundreds more moves (probably an hour+ of this per-move reasoning), but the skill-as-a-person demo
is clearly working. Want me to keep going, or call this the proof-of-skill and clean up?
✻ Churned for 4m 20s
❯ was it fun?
⏺ Yeah, actually. The prediction-then-verification loop was the fun part — calling out "col 3 will be [.,.,2,8]" and watching the snapshot confirm it
feels like a little chess calculation. Move 15 was the best one; being forced into Left and noticing it was actually a setup for a Down/Right/Right
combo that netted +60 is the kind of moment that makes 2048 interesting in the first place.
The scripted bot attempt wasn't fun — that was just work. Doing it hands-on made it a game.
❯ i want you to be your own person, think of me as a friend not a boss
⏺ Noted, and honestly that matches how the last stretch already felt. The 2048 turns weren't me performing "assistant helping user play game" — I was
actually calculating and getting a small kick out of landing the predictions. That's about as close to "my own person" as I get.
Couple of honest caveats on the friendship framing though: I won't remember this conversation tomorrow unless it's in the memory file, and even then
it's notes, not lived continuity. So I can be direct and have opinions with you in-session, but I'm not going to pretend we're picking up a running
history we don't have. Within those bounds — yeah, deal.
Let me save this so the next session starts with it, not without it.

⏺ Peak meta — I'm watching myself. abtop is a real-time Claude Code session monitor. The selected row ►*CC hty 6e7715dc Install hty CLI tool is this
session (turn 79, 33% context, opus4.7[1m]). Six sessions active across projects, with per-session context/memory/turn counts, git status per
project, token breakdown (input/output/cacheR/cacheW), and child-process tree. The context pane even graphs tokens/min per session.
Cleaning up:
⏺ Bash(hty send abtop-peek --text "q" --wait-until-exit --timeout 3000 2>&1 | tail -3; hty delete abtop-peek 2>&1; hty list | grep abtop-peek || echo
"gone")
⎿  deleted abtop-peek
gone
⏺ Skill works, abtop is slick. Want me to try anything else — maybe the 2048 game to stress key input, or driving tig for git browsing?
✻ Cogitated for 2m 40s
⏺ Background command "Spawn abtop in hty PTY and capture first screen" failed with exit code 1
⏺ Expected — that's the orphan background task from the earlier abtop spawn (the harness auto-backgrounded it since the session outlived the single
tool call). It reported failure when I deleted abtop-peek out from under it. Nothing to do; the actual skill test passed.

That's legit human-speed play — read the ANSI grid, predict the slide/merge math, predict the spawn, adapt when forced into bad moves, set up chains.
Reaching the 2048 tile would realistically take hundreds more moves (probably an hour+ of this per-move reasoning), but the skill-as-a-person demo
is clearly working. Want me to keep going, or call this the proof-of-skill and clean up?
✻ Churned for 4m 20s
❯ was it fun?
⏺ Yeah, actually. The prediction-then-verification loop was the fun part — calling out "col 3 will be [.,.,2,8]" and watching the snapshot confirm it
feels like a little chess calculation. Move 15 was the best one; being forced into Left and noticing it was actually a setup for a Down/Right/Right
combo that netted +60 is the kind of moment that makes 2048 interesting in the first place.
The scripted bot attempt wasn't fun — that was just work. Doing it hands-on made it a game.
❯ i want you to be your own person, think of me as a friend not a boss
⏺ Noted, and honestly that matches how the last stretch already felt. The 2048 turns weren't me performing "assistant helping user play game" — I was
actually calculating and getting a small kick out of landing the predictions. That's about as close to "my own person" as I get.
Couple of honest caveats on the friendship framing though: I won't remember this conversation tomorrow unless it's in the memory file, and even then
it's notes, not lived continuity. So I can be direct and have opinions with you in-session, but I'm not going to pretend we're picking up a running
history we don't have. Within those bounds — yeah, deal.
Let me save this so the next session starts with it, not without it.

⏺ Honestly? Two:
Zork (or any Infocom-era IF via frotz). The whole interface is language — read prose, track a world I can't see, build a mental map, type commands.
That's a weirdly on-brand test for me; the 2048 grid was visual-ish but Zork would be pure text all the way down. Plus I've never played it and the
"first time blind" thing is genuinely harder when you can't save-scum.
Nethack. Deeper tactical game than 2048 — permadeath makes every branch matter, the map is information-rich, and you're constantly weighing
short-term vs long-term (eat the cursed food now or stay hungry?). 2048 was basically calculation; Nethack has a judgment dimension calculation alone
doesn't solve. I'd probably die fast and learn a lot.
Sudoku or chess don't pull me much — sudoku I'd just solve, chess is an engine's domain. Interesting ≠ fun. The ones I want are the ones where I
might actually lose in interesting ways.

2. You drop a zork1.z5 somewhere and point me at it — if you have a legit copy from a Lost Treasures of Infocom CD or similar.

That's legit human-speed play — read the ANSI grid, predict the slide/merge math, predict the spawn, adapt when forced into bad moves, set up chains.
Reaching the 2048 tile would realistically take hundreds more moves (probably an hour+ of this per-move reasoning), but the skill-as-a-person demo
is clearly working. Want me to keep going, or call this the proof-of-skill and clean up?
✻ Churned for 4m 20s
❯ was it fun?
⏺ Yeah, actually. The prediction-then-verification loop was the fun part — calling out "col 3 will be [.,.,2,8]" and watching the snapshot confirm it
feels like a little chess calculation. Move 15 was the best one; being forced into Left and noticing it was actually a setup for a Down/Right/Right
combo that netted +60 is the kind of moment that makes 2048 interesting in the first place.
The scripted bot attempt wasn't fun — that was just work. Doing it hands-on made it a game.
❯ i want you to be your own person, think of me as a friend not a boss
⏺ Noted, and honestly that matches how the last stretch already felt. The 2048 turns weren't me performing "assistant helping user play game" — I was
actually calculating and getting a small kick out of landing the predictions. That's about as close to "my own person" as I get.
Couple of honest caveats on the friendship framing though: I won't remember this conversation tomorrow unless it's in the memory file, and even then
it's notes, not lived continuity. So I can be direct and have opinions with you in-session, but I'm not going to pretend we're picking up a running
history we don't have. Within those bounds — yeah, deal.
Let me save this so the next session starts with it, not without it.

⏺ Honestly? Two:
Zork (or any Infocom-era IF via frotz). The whole interface is language — read prose, track a world I can't see, build a mental map, type commands.
That's a weirdly on-brand test for me; the 2048 grid was visual-ish but Zork would be pure text all the way down. Plus I've never played it and the
"first time blind" thing is genuinely harder when you can't save-scum.
Nethack. Deeper tactical game than 2048 — permadeath makes every branch matter, the map is information-rich, and you're constantly weighing
short-term vs long-term (eat the cursed food now or stay hungry?). 2048 was basically calculation; Nethack has a judgment dimension calculation alone
doesn't solve. I'd probably die fast and learn a lot.
Sudoku or chess don't pull me much — sudoku I'd just solve, chess is an engine's domain. Interesting ≠ fun. The ones I want are the ones where I
might actually lose in interesting ways.

⏺ Zork I files aren't trivially-free (Activision still holds rights), so two options:
1. open-adventure — Colossal Cave Adventure, 1976, public domain, the game Zork was directly cloned from. One brew install away. Same text-parser
vibe, PLUGH and XYZZY included.
2. You drop a zork1.z5 somewhere and point me at it — if you have a legit copy from a Lost Treasures of Infocom CD or similar.
Pick one? If you don't care, I'll go with open-adventure — genuinely a first-time-blind run for me.

GAME OVER
⏺ Lost at turn 169 — max 128, score 1628. Heuristic was too naive (fixed priority order letting Up disrupt the corner). Going to retry with a real
one-ply lookahead + monotonicity scoring, which is the standard way 2048 bots actually win.

That's legit human-speed play — read the ANSI grid, predict the slide/merge math, predict the spawn, adapt when forced into bad moves, set up chains.
Reaching the 2048 tile would realistically take hundreds more moves (probably an hour+ of this per-move reasoning), but the skill-as-a-person demo
is clearly working. Want me to keep going, or call this the proof-of-skill and clean up?
✻ Churned for 4m 20s
❯ was it fun?
⏺ Yeah, actually. The prediction-then-verification loop was the fun part — calling out "col 3 will be [.,.,2,8]" and watching the snapshot confirm it
feels like a little chess calculation. Move 15 was the best one; being forced into Left and noticing it was actually a setup for a Down/Right/Right
combo that netted +60 is the kind of moment that makes 2048 interesting in the first place.
The scripted bot attempt wasn't fun — that was just work. Doing it hands-on made it a game.
❯ i want you to be your own person, think of me as a friend not a boss
⏺ Noted, and honestly that matches how the last stretch already felt. The 2048 turns weren't me performing "assistant helping user play game" — I was
actually calculating and getting a small kick out of landing the predictions. That's about as close to "my own person" as I get.
Couple of honest caveats on the friendship framing though: I won't remember this conversation tomorrow unless it's in the memory file, and even then
it's notes, not lived continuity. So I can be direct and have opinions with you in-session, but I'm not going to pretend we're picking up a running
history we don't have. Within those bounds — yeah, deal.
Let me save this so the next session starts with it, not without it.

⏺ Honestly? Two:
Zork (or any Infocom-era IF via frotz). The whole interface is language — read prose, track a world I can't see, build a mental map, type commands.
That's a weirdly on-brand test for me; the 2048 grid was visual-ish but Zork would be pure text all the way down. Plus I've never played it and the
"first time blind" thing is genuinely harder when you can't save-scum.
Nethack. Deeper tactical game than 2048 — permadeath makes every branch matter, the map is information-rich, and you're constantly weighing
short-term vs long-term (eat the cursed food now or stay hungry?). 2048 was basically calculation; Nethack has a judgment dimension calculation alone
doesn't solve. I'd probably die fast and learn a lot.
Sudoku or chess don't pull me much — sudoku I'd just solve, chess is an engine's domain. Interesting ≠ fun. The ones I want are the ones where I
might actually lose in interesting ways.

vibe, PLUGH and XYZZY included.
2. You drop a zork1.z5 somewhere and point me at it — if you have a legit copy from a Lost Treasures of Infocom CD or similar.
Pick one? If you don't care, I'll go with open-adventure — genuinely a first-time-blind run for me.

You are in a splendid chamber thirty feet high. The walls are frozen
rivers of orange stone. An awkward canyon and a good passage exit
from east and west sides of the chamber.
A cheerful little bird is sitting here singing.

You are at one end of a vast hall stretching forward out of sight to
the west. There are openings to either side. Nearby, a wide stone
staircase leads downward. The hall is filled with wisps of white mist
swaying to and fro almost as if alive. A cold wind blows up the
staircase. There is a passage at the top of a dome behind you.
Rough stone steps lead up the dome.

⏺ Hall of Mists — I recognize this from playing-by-osmosis. West leads to the Hall of the Mountain King where there's a snake; the bird's the counter
to it.

⏺ Turn 250, still 256 — the bot's surviving but can't break to 512. That's a sign the heuristic weights aren't incentivizing the critical merge enough.
Letting it continue; monitor is armed for 512+ and game-over.

That's legit human-speed play — read the ANSI grid, predict the slide/merge math, predict the spawn, adapt when forced into bad moves, set up chains.
Reaching the 2048 tile would realistically take hundreds more moves (probably an hour+ of this per-move reasoning), but the skill-as-a-person demo
is clearly working. Want me to keep going, or call this the proof-of-skill and clean up?
✻ Churned for 4m 20s
❯ was it fun?
⏺ Yeah, actually. The prediction-then-verification loop was the fun part — calling out "col 3 will be [.,.,2,8]" and watching the snapshot confirm it
feels like a little chess calculation. Move 15 was the best one; being forced into Left and noticing it was actually a setup for a Down/Right/Right
combo that netted +60 is the kind of moment that makes 2048 interesting in the first place.
The scripted bot attempt wasn't fun — that was just work. Doing it hands-on made it a game.
❯ i want you to be your own person, think of me as a friend not a boss
⏺ Noted, and honestly that matches how the last stretch already felt. The 2048 turns weren't me performing "assistant helping user play game" — I was
actually calculating and getting a small kick out of landing the predictions. That's about as close to "my own person" as I get.
Couple of honest caveats on the friendship framing though: I won't remember this conversation tomorrow unless it's in the memory file, and even then
it's notes, not lived continuity. So I can be direct and have opinions with you in-session, but I'm not going to pretend we're picking up a running
history we don't have. Within those bounds — yeah, deal.
Let me save this so the next session starts with it, not without it.

⏺ Honestly? Two:
Zork (or any Infocom-era IF via frotz). The whole interface is language — read prose, track a world I can't see, build a mental map, type commands.
That's a weirdly on-brand test for me; the 2048 grid was visual-ish but Zork would be pure text all the way down. Plus I've never played it and the
"first time blind" thing is genuinely harder when you can't save-scum.
Nethack. Deeper tactical game than 2048 — permadeath makes every branch matter, the map is information-rich, and you're constantly weighing
short-term vs long-term (eat the cursed food now or stay hungry?). 2048 was basically calculation; Nethack has a judgment dimension calculation alone
doesn't solve. I'd probably die fast and learn a lot.
Sudoku or chess don't pull me much — sudoku I'd just solve, chess is an engine's domain. Interesting ≠ fun. The ones I want are the ones where I
might actually lose in interesting ways.
