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 | $0.00090 | $0.01502 |
| Opus 5.5 | $0.00036 | $0.00601 |
| Sonnet 5.5 | $0.00018 | $0.00300 |
| Haiku 4.5 | $0.00009 | $0.00150 |
Grade A, and why
motion-video 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 today.
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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Motion video
Make a 1920×1080 30 fps motion-graphic video where the scene cuts land on the music's beats, reveals land on spoken words, and the audio is broadcast-clean. The workflow is fully scripted: facts → script → multix audio → forced alignment → beat grid → bar-spliced music → timeline + mix → HTML composition → lint/check/snapshot → render → remux → social encode.
Two finished editions show what each style should feel like. Their working
projects are deliberately not bundled here: the generated voice-over, music and
SFX are large and provider-licensed. Study the published demo, then build every
new video from assets/templates/index-skeleton.html plus the style reference.
| Style | Style reference | Public demo | Feel |
|---|---|---|---|
| Comic multiverse | references/style-comic-spiderverse.md |
Dewee v3.34 comic edition, the 151 s social encode | loud, playful, hand-made |
| Glass keynote | references/style-glass-keynote.md |
the 144 s edition of the same release | premium, calm, clear |
Scope
This skill handles:
- New videos in either style, restyles of an existing video as a separate project, and partial reworks (new music, re-timed drops, re-mix, re-render, social encode).
- Audio through the
multixCLI: Gemini TTS voice, ElevenLabs SFX, ElevenLabs Music composition plans, ElevenLabs forced alignment.
This skill does NOT handle:
- Generative text-to-video footage (use
multixSeedance/Veo directly). - React/Remotion compositions or generic HyperFrames questions (use the hyperframes or remotion skills).
- Publishing to social accounts: produce the file and let the user post it.
How to work
- Pin the outcome before touching files: topic and sources, style (one of the two, or a new one derived from them), duration, voice language (English VO + Vietnamese captions by default), ending, signature. Ask only if the style or the facts source is unknown.
- Create
assets/videos/<slug>/(never overwrite a finished edition) and a plan underplans/following the repo convention. Copy the templates fromassets/templates/of this skill:scripts/*.mjs,data/*.example.json(rename to.json),hyperframes.json,index-skeleton.htmlasindex.html, plusscripts/fit-beat-grid.py. - Follow
references/production-pipeline.mdstep by step. Each step writes a file the next one reads, so do not reorder them. - Get the music right with
references/audio-and-beat-sync.md: fit the grid, splice bars so the drops land where the script needs them, verify the splice, and measure the voice/music balance. - Build
index.htmlwithreferences/composition-contract.mdand the chosen style reference, starting fromassets/templates/index-skeleton.html. When a scene type repeats (stats, diagrams, charts, terminal, graph, outro), follow the demo's choreography for that scene instead of inventing a new one. - Finish only when every check in "Done when" passes; report measured numbers, not impressions.

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.

motion-video is a skill published in the GitHub repository bestagentkits/motion-video-skill (121 stars, last pushed 18d ago), licensed MIT. It adds 90 tokens to every session and 1,502 once invoked, about $0.0004 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 2026-10-16.
