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 | $0.00015 | $0.00307 |
| Opus 5 | $0.00008 | $0.00153 |
| Sonnet 5 | $0.00003 | $0.00061 |
| Haiku 4.5 | $0.00002 | $0.00031 |
Grade A, and why
video-frames 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 3d 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.
What it actually says
Video Frames (ffmpeg)
Extract a single frame from a video, or create quick thumbnails for inspection.
Quick start
First frame:
ffmpeg -hide_banner -loglevel error -y \
-i /path/to/video.mp4 \
-vf "select=eq(n\,0)" \
-vframes 1 \
/tmp/frame.jpg
At a timestamp:
ffmpeg -hide_banner -loglevel error -y \
-ss 00:00:10 \
-i /path/to/video.mp4 \
-frames:v 1 \
/tmp/frame-10s.jpg
By frame index:
ffmpeg -hide_banner -loglevel error -y \
-i /path/to/video.mp4 \
-vf "select=eq(n\,42)" \
-vframes 1 \
/tmp/frame42.jpg
Notes
- Prefer
-ss+ timestamp for "what is happening around here?". - Use
.jpgfor quick sharing; use.pngfor crisp UI frames. - Use
-hide_banner -loglevel errorto suppress verbose ffmpeg output.
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.

video-frames is a skill published in the GitHub repository the-open-agent/openagent (5,596 stars, last pushed yesterday), licensed Apache-2.0. It adds 15 tokens to every session and 307 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.
