Author dedicated Storybook visual regression stories for 2nd-gen components. Use when adding or reviewing `.vrt.ts` files, Chromatic VRT coverage, forced-colors coverage, pseudo-state snapshots, global stylesheet coverage, or custom-property VRT coverage.
Phase 3 of 1st-gen to 2nd-gen component migration. Use to move properties, methods, and types from 1st-gen to 2nd-gen while maintaining a clear public API.
Create accessibility migration analysis docs for 2nd-gen component migration. Use when on the "analyze accessibility" step for one or more components.
Phase 5 of 1st-gen to 2nd-gen component migration. Use to migrate CSS to the 2nd-gen structure, apply Spectrum 2 tokens, and ensure stylelint passes.
Upgrade Spectrum 1 (sp-* elements, @spectrum-web-components/*) to Spectrum 2 (swc-* elements, @adobe/spectrum-wc). Use when developers need to migrate from Spectrum 1 to Spectrum 2 web components, or when they mention @spectrum-web-components, sp-* elements, or Spectrum 1.
Build UIs with Spectrum Web Components (SWC), Adobe's Spectrum 1 web component library. Use when developers are working with @spectrum-web-components/* packages or sp-* custom elements. Includes component API references, usage examples, accessibility guidance, and integration guides.

Phase 6 of the 1st-gen → 2nd-gen component migration. The goal is automated test coverage for behavior and accessibility — unit tests via Vitest, a11y tests via Playwright, and Storybook play functions.
You are a skeptic. Tests that always pass are not tests — they are documentation. Use the test-driven-development skill to ensure that each test would be able to catch a real regression. Write the failure case before writing the assertion. If you cannot imagine how a test could fail, it is not testing enough and should use ask-questions to flag the concern with the user.
Read the migration plan at CONTRIBUTOR-DOCS/03_project-planning/03_components/[component]/migration-plan.md when available before writing tests. Use it to derive the must-ship test matrix, breaking-change coverage, accessibility and behavior regressions, and any high-risk open questions that need regression protection. If it is missing, stale, or intentionally incomplete, derive the needed context from the implemented behavior and source material and call out the missing plan as a risk. See also migration-plan-contract.
Follow Phase 6: Testing in the washing machine workflow doc — it covers what to do, what to check, common problems, and the quality gate for this phase.
If the implementation or the needed test coverage has drifted from the migration plan, follow migration-plan-contract.
For dedicated visual regression stories (test/vrt/*.vrt.ts), also use the vrt-authoring skill.
@storybook/test's userEvent dispatches synthetic events (isTrusted === false), which browser-native popover/<dialog> light-dismiss (Escape, outside/backdrop click) ignores, so a synthetic Escape does not dismiss a native overlay. Test that native path in the Playwright accessibility spec (test/<component>.a11y.spec.ts), which drives real, trusted input, not in a play function. Play-function files (test/<component>.test.ts) are indexed as dev Storybook stories, and importing vitest/browser there throws outside the Vitest runner, breaking the dev server. Component-authored JavaScript handlers (click-to-toggle, focus, keydown backstops) work with the synthetic @storybook/test userEvent and stay in play functions. See Native dismissal and trusted input for the full pattern.
