description	Scaffold a new React component with optional Storybook story and Vitest test files. Use this skill whenever the user asks to "create a component", "make a button", "scaffold a card", "add a new component", or asks for a new file under `app/components/` following the project's component pattern (PascalCase folder, index.tsx, tests/).

new-component

Trigger: user asks to create a component, scaffold a card, etc.

Workflow

1. Confirm with user via AskUserQuestion: name (PascalCase), parent dir (default app/components), props (or "none"), story (default yes).
2. Run: .gaia/cli/gaia scaffold component <Name> [flags]
3. Verify: pnpm typecheck clean. Open the new files, sanity-check the props.
4. If user wants more (variants, conditional rendering, complex children): edit the generated files. The skill does not regenerate.

Flags

• --no-story — skip Storybook story
• --parent <dir> — non-default parent dir (e.g. app/components/Form)
• --props "a:string,b:number" — typed props rendered as a Props alias and destructured in the signature

Accessibility assertion

Scaffolded test files include a test('a11y') block that calls expectNoA11yViolations from test/a11y.ts (axe-core, full default ruleset — no tag filter). Because axe-core is incompatible with the project's default happy-dom test environment (Node.prototype.isConnected is getter-only — capricorn86/happy-dom#978), the scaffolder writes // @vitest-environment jsdom as the first line of the test file. The directive is required: expectNoA11yViolations throws an actionable error if it detects a non-jsdom runtime. Don't strip the directive when editing the file.
