gsap-transform: Instructions file for GitHub Copilot

.github/instructions/motion-studio.instructions.md

gsap-transform motion-studio.instructions.md is an instructions file for GitHub Copilot from taotao135791-bit/gsap-transform. It costs 368 tokens per session, scanned A, original, MIT.

Instructions for producing previewable animation videos with GSAP, a JavaScript animation library, using a self-contained project. It covers previewing and rendering the result as a video file.

In plain words
What is it for?
Creating effect-video previews and rendering animations to MP4, WebM, or MOV files from GSAP projects.
Why use it?
It gives the agent a defined delivery process for turning animation work into a viewable artifact. It also records project and rendering requirements that help avoid common browser and timing problems.

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

gsap-transform motion-studio.instructions.md 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.

What it actually says

motion-studio — video delivery shell instructions

When the user wants the output as a video file (mp4/webm/mov) or a previewable "effect video" artifact, produce a self-contained preview project per skills/motion-studio/SKILL.md:

  • Default path: pick or create projects/{slug}/state.json, then run node scripts/state-to-scene.mjs projects/{slug}.
  • Copy shell files from skills/motion-studio/templates/ only when a project scaffold is missing.
  • Generated scene.js must expose window.__studio = { gsap, tl, duration }.
  • Gate GSDevTools.create() on !window.__RENDERING; default-import every plugin (incl. GSDevTools — Anti-Slop G4/G6.3); gate SplitText on document.fonts.ready (G6.5).
  • Preview: node serve.mjs (NOT file:// — ES modules are CORS-blocked at origin null). Render: node render.mjs --preset vertical or another supported preset.

render.mjs seeks with tl.time(t) — NOT gsap.updateRoot() (a matchMedia timeline is not on globalTimeline; updateRoot leaves it parked at its end state). The four rendering gotchas (file:// CORS, matchMedia seek, tl-object serialization timeout, headless rAF) are baked into the script.

Tuning is chat-driven through state.json by default: edit state, regenerate scene.js, and refresh the preview tab. Direct scene edits require an explicit user-chosen escape hatch.

Run motion-anti-slop Group G6 before declaring a preview project done.

Changes

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.
