Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Rogue Agent · line 73 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
- medium Excessive Agency · line 6 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.00694 |
| Opus 5 | $0.00015 | $0.00347 |
| Sonnet 5 | $0.00006 | $0.00139 |
| Haiku 4.5 | $0.00003 | $0.00069 |
Grade A, and why
play scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/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
fileprovided -> skip Phase 1 (file selection) - If
-sprovided -> skip Phase 2 (speed selection) - If any of
-i/-l/-r/-mprovided -> skip Phase 3 (options)
Workflow
- Preflight: Check iTerm2 and asciinema
- Discovery: Find .cast files
- Selection: AskUserQuestion for file
- Speed: AskUserQuestion for playback speed
- Options: AskUserQuestion for additional options
- 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 |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

play is a skill published in the GitHub repository terrylica/cc-skills (66 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 694 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
