Reference for asciinema v3 .cast NDJSON format. TRIGGERS - cast format, asciicast spec, event codes.
From asciinema-toolsnpx claudepluginhub terrylica/cc-skills --plugin asciinema-toolsThis skill is limited to using the following tools:
references/evolution-log.mdDispatches parallel agents to independently tackle 2+ tasks like separate test failures or subsystems without shared state or dependencies.
Executes pre-written implementation plans: critically reviews, follows bite-sized steps exactly, runs verifications, tracks progress with checkpoints, uses git worktrees, stops on blockers.
Guides idea refinement into designs: explores context, asks questions one-by-one, proposes approaches, presents sections for approval, writes/review specs before coding.

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.
| Argument | Description |
|---|---|
header | Show header field specification |
events | Show event codes deep-dive |
parsing | Show jq/bash parsing examples |
all | Show complete format reference |
-f, --file | Use specific .cast for examples |
--live | Run parsing examples on file |
Invoke the asciinema-cast-format skill with user-selected section.
-f provided with parsing -> skip Phase 2 (example file)# Show header format
/asciinema-tools:format header
# Show event codes
/asciinema-tools:format events
# Parse specific file with live examples
/asciinema-tools:format parsing -f session.cast --live
| Issue | Cause | Solution |
|---|---|---|
| File not found | Invalid path | Use absolute path or ensure file exists |
| Parse error | Invalid NDJSON | Check file is valid asciinema v3 format |
| No output | Missing section | Specify one of: header, events, parsing, all |
