Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00032 | $0.02330 |
| Opus 5 | $0.00016 | $0.01165 |
| Sonnet 5 | $0.00006 | $0.00466 |
| Haiku 4.5 | $0.00003 | $0.00233 |
Grade B, and why
asciinema-recorder scanned grade B with 1 finding 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 13d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo apt install asciinema How it starts
The opening of the file, as written. The whole thing — 346 lines — stays where its author put it; the contents beside it link to each section on GitHub.
asciinema-recorder
Generate ready-to-copy commands for recording Claude Code sessions with asciinema. Dynamically creates filenames based on workspace and datetime.
Platform: macOS, Linux (requires asciinema CLI)
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.
When to Use This Skill
Use this skill when:
- Starting a new terminal recording session
- Creating demos or documentation recordings
- Capturing Claude Code sessions for review or sharing
- Generating workspace-specific recording filenames
Why This Skill?
This skill generates ready-to-copy recording commands with:
- Dynamic workspace-based filename
- Datetime stamp for uniqueness
- Saves to project's tmp/ folder (gitignored)
Requirements
| Component | Required | Installation |
|---|---|---|
| asciinema CLI | Yes | brew install asciinema |
Workflow Phases
Phase 0: Preflight Check
Purpose: Verify asciinema is installed.
# Check asciinema CLI
which asciinema && asciinema --version
If asciinema is NOT installed, use AskUserQuestion:
- question: "asciinema not found. How would you like to proceed?"
header: "Setup"
multiSelect: false
options:
- label: "Install asciinema (Recommended)" description: "Run: brew install asciinema (macOS) or apt install asciinema (Linux)"
- label: "Show manual instructions" description: "Display installation commands for all platforms"
- label: "Cancel" description: "Exit without recording"
Based on selection:
-
"Install asciinema" → Run appropriate install command based on OS:
# macOS brew install asciinema # Linux (apt) sudo apt install asciinema # Linux (pip) pip install asciinemaThen proceed to Phase 1.0.
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.

asciinema-recorder is a skill published in the GitHub repository terrylica/cc-skills (73 stars, last pushed today), licensed MIT. It adds 32 tokens to every session and 2,330 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
