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 | $0.00043 | $0.00904 |
| Opus 5.5 | $0.00017 | $0.00362 |
| Sonnet 5.5 | $0.00009 | $0.00181 |
| Haiku 4.5 | $0.00004 | $0.00090 |
Grade A, and why
video-production 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 1mo 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 — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Video Production
Production contract
Before rendering, establish audience, script/storyboard, asset order and timing, aspect ratio, resolution, audio/caption requirements and intended delivery. Inventory local sources, ownership/license/consent, and missing assets. Do not invent provenance or assume that a technical pass establishes usage rights. Keep that editorial production checklist alongside the project.
Use the script below for straight-cut, 16:9 local assembly. For programmatic animation use the separately installed official Remotion skill; this skill does not install Remotion or provide a rendering backend. Generating images, video, voice or TTS is an optional external capability: verify availability, consent, cost and upload permission first. Missing generation capability is not a reason to block assembly when local assets suffice. Never publish automatically.
Local execution
Requires Python 3.10+, ffmpeg with libx264/AAC and ffprobe on PATH. Report
missing binaries/codecs explicitly; do not silently install, substitute a cloud
service, or claim an unavailable render succeeded.
Write a UTF-8 JSON manifest; relative paths resolve against its directory:
{
"clips": [
{"path": "title.png", "kind": "image", "duration": 2},
{"path": "demo.mp4", "kind": "video", "duration": 3}
],
"audio": "narration.wav",
"subtitles": "captions.srt"
}
Run from this skill directory (or use an absolute script path):
python3 scripts/produce.py /project/manifest.json /project/preview-v1 --mode preview
python3 scripts/produce.py /project/manifest.json /project/final-v1 --mode final
Output directories must be new. Original assets are not overwritten. The helper accepts PNG/JPEG stills, MP4/MOV videos, optional WAV/MP3/M4A audio, and UTF-8 SRT captions only. Unknown manifest fields and unsupported extensions are errors. Use ordinary standalone local media, not playlists or externally linked media. Do not process untrusted media without an appropriately isolated environment; this helper is not a sandbox.
What ships with it
2 files 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.

video-production is a skill published in the GitHub repository holon-run/holon (166 stars, last pushed yesterday), licensed Apache-2.0. It adds 43 tokens to every session and 904 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 2026-09-15.
