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.

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 | $0.00039 | $0.00555 |
| Opus 5.5 | $0.00016 | $0.00222 |
| Sonnet 5.5 | $0.00008 | $0.00111 |
| Haiku 4.5 | $0.00004 | $0.00056 |
Grade A, and why
screen-recording 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 16d 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.

AI Builder - Screen Recording
This skill controls a macOS-only screen recorder via CLI. It records the main monitor using ffmpeg and captures audio using sox, both running in tmux sessions.
When to Use This Skill
- You need to start screen recording and keep it running in the background.
- You need to stop recording later and produce a final mp4 file.
- You need a CLI-only flow (not MCP) for screen recording.
Your Roles in This Skill
- QA Engineer: Verify recording start/stop behavior and output file correctness.
- DevOps Engineer: Manage background tmux lifecycle and dependency checks.
Role Communication
As an expert in your assigned roles, you must announce your actions before performing them using the following format:
As a {Role} [and {Role}, ...], I will {action description}
This communication pattern ensures transparency and allows for human-in-the-loop oversight at key decision points.
Instructions
Follow these steps in order.
Step 1: Verify Environment
- macOS only.
ffmpeg,sox, andtmuxmust be available inPATH.- Run commands from project root.
Step 2: Start Recording
core/bin/mac-screen-recording start
Optional arguments:
core/bin/mac-screen-recording start --fps 30 --output .skillpilot/temp/screen-recording/my-session.mp4
If ffmpeg device auto-detection fails on your machine, pass the screen device index explicitly:
core/bin/mac-screen-recording start --screen-device-index 1
Step 3: Check Status
core/bin/mac-screen-recording status
Step 4: Stop Recording
core/bin/mac-screen-recording stop
This stops tmux sessions, finalizes media, and writes the final mp4 path in output JSON.
Expected Output
start: JSON withrun_id, output path, and tmux session names.status: JSON showing whether recording is active and tmux sessions are alive.stop: JSON withfinal_filepath.
Key Principles
- Keep one active recording at a time per state file.
- Always use
stopto finalize output cleanly. - Use default state path
.skillpilot/temp/screen-recording/state.jsonunless a different workflow is required.
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.

screen-recording is a skill published in the GitHub repository X-School-Academy/skill-pilot (20 stars, last pushed 4mo ago), licensed MIT. It adds 39 tokens to every session and 555 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-02.
