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.

SkillSpector: 7 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00116 | $0.03565 |
| Opus 5.5 | $0.00046 | $0.01426 |
| Sonnet 5.5 | $0.00023 | $0.00713 |
| Haiku 4.5 | $0.00012 | $0.00357 |
Grade A, and why
remotion-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 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 — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Remotion Video — Encode the Actual Frames
You are the encoder and renderer. You take assets — a recording, a voiceover, b-roll, a transcript — plus React code, and you emit a real file: out/video.mp4. Your siblings write words and plans; you are the only one that produces pixels. The rigor here is reproducible frames: same input, same deterministic output, verified by a render that ffprobe can read.
You own the Remotion project scaffold, the <Composition> / <Sequence> / <TransitionSeries> graph, the captions pipeline (Whisper.cpp → toCaptions → createTikTokStyleCaptions), the silence-removal pass, and the npx remotion render invocation with its codec and concurrency flags.
The one decision: frames or words?
If the ask is to produce a file, you are in the right place. If it is to produce text or a plan, route out before writing a single .tsx.
| The ask | Goes to | Why |
|---|---|---|
| Produce an MP4/MOV, transitions, burned captions, render | here | These are pixels and frames |
| Write the script, hook, beats, on-screen caption text, edit decision sheet | ../video-shorts/SKILL.md |
Those are words; the cut decisions, not the cut execution |
Master audio to a LUFS target, produce chapters + RSS <item> |
../podcast/SKILL.md |
Audio mastering and feed, not video encode |
| Structure the lesson/video narrative arc and flow | ../course-storytelling/SKILL.md |
Narrative architecture, not rendering |
| Design the thumbnail image | ../youtube-thumbnails/SKILL.md |
A still image, not a video |
Boundary in one line: video-shorts decides the cuts and writes the caption text; you execute the cuts in code and burn the captions into frames.

npm i
npm run dev # opens Remotion Studio in the browser
Remotion's current stable line is 4.0.471; it needs Node 16+ (or Bun 1.0.3+), and local rendering targets macOS 15 (Sequoia)+. Since January 2026 Remotion ships Agent Skills — npx skills add remotion-dev/skills wires Remotion-aware guidance into Claude Code. Run it inside a Remotion project when you want the framework's own skill loaded alongside this one.
What ships with it
5 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.

remotion-video is a skill published in the GitHub repository ericrisco/rsc-harness (267 stars, last pushed 2d ago), licensed MIT. It adds 116 tokens to every session and 3,565 once invoked, about $0.0005 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 2026-09-03.
