Character Animation QA

Use this skill before presenting a character-animation preview or final render.

Review Layers

1. Schema validation: character design, rig plan, pose library, action timeline.
2. Static asset checks: referenced parts and backgrounds exist.
3. Browser preview: load the preview, capture screenshots, collect console errors.
4. Motion check: compare sampled frames for non-trivial differences.
5. Final MP4 check: ffprobe metadata, duration, resolution, audio, frame samples.
6. Agent visual review: inspect sampled frames for detached limbs, bad layers,

off-frame characters, unreadable expressions, broken text.

Playwright Pattern

ts
const browser = await chromium.launch();
const page = await browser.newPage({ viewport: { width: 1280, height: 720 } });
await page.goto(previewUrl, { waitUntil: "networkidle" });
await page.screenshot({ path: "preview.png" });

Pass/Revise/Fail

• pass: technical checks pass, acting is readable.
• revise: fixable rig/timeline issue.
• fail: missing assets, blank render, runtime failure, or wrong runtime.
