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: 4 findings, up to medium
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 | $0.00072 | $0.01297 |
| Opus 5.5 | $0.00029 | $0.00519 |
| Sonnet 5.5 | $0.00014 | $0.00259 |
| Haiku 4.5 | $0.00007 | $0.00130 |
Grade A, and why
remotion-video-toolkit 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 — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Remotion Video Toolkit
Write React components, get real MP4 videos. This skill teaches your AI agent how to build with Remotion — from a first animation to a production rendering pipeline.
29 rules. Every major Remotion feature covered.
What you can build with this
Personalized video at scale Feed user data as JSON props, render a unique video per user. Think Spotify Wrapped, GitHub Unwrapped, onboarding walkthroughs — one template, thousands of outputs.
Automated social media clips Pull live data (stats, leaderboards, product metrics) and render daily or weekly video posts without anyone touching a timeline editor.
Dynamic ads and marketing videos Swap in customer name, product image, pricing. Same template, infinite variations. Render server-side via API or Lambda.
Animated data visualizations Turn dashboards and KPI reports into shareable video clips with animated charts and transitions.
TikTok and Reels captions Transcribe audio, display word-by-word highlighted subtitles, export ready for upload.
Product showcase videos Auto-generate from your database — images, specs, pricing — straight to MP4.
Educational and explainer content Animated course materials, certificate videos, step-by-step walkthroughs — all driven by code.
Video generation as a service Expose rendering as an HTTP endpoint. Your app sends JSON, gets back a video file.
Requirements
- Node.js 18+
- React 18+ (Remotion renders React components frame-by-frame)
- Remotion — scaffold with
npx create-video@latest - FFmpeg — ships with
@remotion/renderer, no separate install needed - For serverless rendering: AWS account (Lambda) or GCP account (Cloud Run)
What's inside
Core
| Rule | Description |
|---|---|
| Compositions | Define videos, stills, folders, default props, dynamic metadata |
| Rendering | CLI, Node.js API, AWS Lambda, Cloud Run, Express server patterns |
| Calculate metadata | Set duration, dimensions, and props dynamically at render time |
What ships with it
34 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.
- 1mo ago First seen · 150 lines · 72 tokens per session scan A 140a3e508a44
remotion-video-toolkit is a skill published in the GitHub repository zai-org/Synapse (513 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 72 tokens to every session and 1,297 once invoked, about $0.0003 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 2026-08-30.
