Diagnose a concrete rendered hitch or stutter.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Animation Jank QA

Use this skill for symptom-led runtime diagnosis. Start from a reproducible jank case and determine whether it comes from main-thread work, layout/paint, asset pressure, scroll coupling, competing animation systems, or lifecycle cleanup.

## Workflow

1. Reproduce the exact affected route, interaction, viewport, and device class.
2. Read [Animation Jank QA Guide](references/animation-jank-qa-guide.md) for relevant diagnosis and retesting steps.
3. Run the narrowest meaningful trace or rendered check for the symptom; inspect frame timing, long tasks, forced layout, paint/compositing, asset decode, observers, timers, and RAF loops as applicable.
4. Fix issues when they are in scope; otherwise record exact evidence and remaining risk.
5. Retest the original symptom and summarize commands, URLs, traces/screenshots, changed files, and what was not tested.

## Always Protect

- Inspect the framework, motion stack, affected media, component lifecycle, and available browser/performance tooling before changing code.

How to install

The exact contents, by fingerprint
mdr add thegoat395/codex-skills/animation-jank-qa@sha256:177171bc6df3fb92

The line at the top of this page pins the label git:20260905.f7824ba, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
