Use when writing, changing, debugging, or reviewing the Playwright component tests that mount stories. That covers specs in packages/app/component-tests or packages/session-ui/component-tests, `*.fixture.tsx` files there or beside source (such as packages/gui-plugins/src/browser/panel.fixture.tsx), the stories they mount, and the shared harness in packages/stories (playwright/config.ts, playwright/story.ts, vite.config.ts, src/frame.tsx, src/index-plugin.ts, mocks). Also use when a component test is flaky, passed on retry, or fails with "Execution context was destroyed", "Failed to fetch dynamically imported module", or `#story-root` hidden. Covers mount args, source modules imported by URL, Vite dependency pre-bundling and reloads, a cold vs warm story server, mobile drawers, geometry, and checks before pushing.

From the source SKILL.md

Each package suite starts one story server, a plain Vite dev server for packages/stories, and every worker shares it (packages/stories/playwright/config.ts:17-26; CI uses 2 workers, config.ts:15). With fullyParallel (config.ts:12), the tests of one file run on several workers in any order. There is no backend: server, SDK and sync modules are in-page mocks. Every test gets a fresh context, and mount is a full page navigation to the frame (packages/stories/playwright/story.ts:37). Slow or flaky component tests in CI have come from five sources: the shared server's dependency optimizer, module…
