Token cost

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.

Security

Grade A, and why

video-editing 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/verify-render.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 677 lines — stays where its author put it; the contents beside it link to each section on GitHub.

video-editing

Use this skill when you have an approved script, provided voice/talking-head media, and gathered assets, and need to turn them into a finished vertical (9:16) short. You are the main editor, not a clip-stitcher. The bar is creator-grade shorts (Kallaway / Varun Mayya density): every beat earns attention. Generic AI-tool output — uniform 1s cuts, default fonts, linear/jittery transforms, a stock-template look — is a failure, not a deliverable.

Default ratio is 9:16 (1080×1920). The style packs also define 16:9 and 1:1 behavior, so the same look can be retargeted — but this skill's pacing and hook grammar are written for vertical short-form first.

The non-negotiable workflow (never skip, never reorder)

Authoring index.html by hand from nothing breaks live-reload and project structure. Always:

  1. npx hyperframes init edit inside your project's edit/ folder — creates the scaffold (index.html, meta.json, hyperframes.json, CLAUDE.md, package.json).
  2. cd edit and modify the generated project files to build the actual edit. Add fonts/, assets/sfx/, sub-compositions under compositions/.
  3. npx hyperframes preview (long-running — run in background) — verify in the browser with live reload. Use a browser tool to inspect and screenshot. Confirm pacing, layout, text timing, and animation smoothness before rendering.
  4. npx hyperframes lint / npm run check — fix every error; review warnings.
  5. npx hyperframes render — final MP4.
  6. Verify: ffprobe (9:16 dimensions, duration, codec) + ffmpeg frame spot-checks against a contact sheet. Run the bundled gate script (below).

Use the hyperframes docs (npx hyperframes docs) for API/feature reference and the references in this skill for the editing standard. If HyperFrames tooling is missing or broken, stop and tell the user rather than hand-authoring a generic edit.

Requirements

  • HyperFrames — the rendering engine, run via npx hyperframes. This skill is the editing standard on top of HyperFrames; it does not replace it.
  • Node.js (for npx and the verification script).
  • ffmpeg / ffprobe on PATH — for SFX synthesis, audio mixing, and render verification.
  • A style pack under styles/<style>/FRAME.md (this skill ships vibe-life as a worked example and _template as a starting point — see styles/README.md).

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.
