/asciinema-tools:play

Play terminal recordings in a dedicated iTerm2 window.

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

Arguments

Argument	Description
file	Path to .cast file
-s, --speed	Playback speed (e.g., -s 6)
-i, --idle-time-limit	Max idle time in seconds
-l, --loop	Loop playback
-r, --resize	Match terminal to recording size
-m, --markers	Pause on markers

Execution

Invoke the asciinema-player skill with user-selected options.

Skip Logic

• If file provided -> skip Phase 1 (file selection)
• If -s provided -> skip Phase 2 (speed selection)
• If any of -i/-l/-r/-m provided -> skip Phase 3 (options)

Workflow

1. Preflight: Check iTerm2 and asciinema
2. Discovery: Find .cast files
3. Selection: AskUserQuestion for file
4. Speed: AskUserQuestion for playback speed
5. Options: AskUserQuestion for additional options
6. Launch: Open iTerm2 via AppleScript

Examples

# Play recording at normal speed
/asciinema-tools:play session.cast

# Play at 6x speed
/asciinema-tools:play session.cast -s 6

# Play with idle time limit and looping
/asciinema-tools:play session.cast -i 2 -l

Troubleshooting

Issue	Cause	Solution
iTerm2 not found	Not installed	brew install --cask iterm2
Window not opening	AppleScript issue	Grant iTerm2 accessibility permissions
Playback stuttering	Large file	Use -i 1 to cap idle time

Post-Execution Reflection

After this skill completes, check before closing:

1. Did the command succeed? — If not, fix the instruction or error table that caused the failure.
2. Did parameters or output change? — If the underlying tool's interface drifted, update Usage examples and Parameters table to match.
3. Was a workaround needed? — If you had to improvise (different flags, extra steps), update this SKILL.md so the next invocation doesn't need the same workaround.

Only update if the issue is real and reproducible — not speculative.
