How this skill gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Visual Regression Lab
Use this skill to capture comparable browser evidence and inspect visual regressions. Scope routes, viewports and states to the requested comparison; a capture alone does not prove quality.
Required Checks
1. Start or identify the local server. 2. Open the relevant route in a browser or Playwright. 3. Capture the relevant supported viewports and states, using the same conditions for baseline and candidate. 4. Check console errors, failed requests, layout overflow, missing media, and text clipping. 5. Inspect first viewport composition, hierarchy, spacing, typography, image crops, and CTA visibility. 6. Test key interactions: nav, forms, menus, tabs, accordions, hover states, focus states, and modals. 7. For animation-heavy work, test reduced-motion behavior and watch for jank. 8. For canvas/WebGL/video, verify nonblank rendered pixels and stable framing. 9. Report observed differences with evidence. Repair only when authorized, then recapture affected states; no fixed polish-pass or edit quota applies.
Read [baseline contract](references/baseline-contract.md). When a project has Playwright installed, run `node "<skill-root>/scripts/capture-settled-baseline.mjs" <url> <output-dir>` to capture settled desktop/mobile/reduced-motion states and a machine-readable inspection manifest.
When native full-page capture is blank, sparse, incomplete, or inconsistent with real scrolling, read [stitched full-page capture](references/stitched-full-page-capture.md) and run `node "<skill-root>/scripts/capture-stitched-full-page.mjs" --url <url> --output <image>`. Treat the stitched image as evidence only after visual inspection.
Output
Report:
- routes/viewports checked
- screenshots or saved paths when available
- issues found and fixed
- commands run
- anything not tested
Resolve `<skill-root>` to this skill folder's actual absolute location; preserve project-local module resolution for Node capture tools.
