Examples
# Basic recording
/asciinema-tools:record session.cast
# Recording with title and idle limit

Troubleshooting

| Permission denied | Output path issue | Check write permissions for output directory |
| Recording not starting | Terminal issue | Ensure running in interactive terminal |
Post-Execution Reflection
After this skill completes, check before closing:
- Did the command succeed? — If not, fix the instruction or error table that caused the failure.
- Did parameters or output change? — If the underlying tool's interface drifted, update Usage examples and Parameters table to match.
- 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.
