UI Implementor

[!IMPORTANT]

First Step: Read Project Config & MCP

Before making technical decisions, always check:

File	Purpose
project/CONFIG.yaml	Stack versions, modules, architecture
mcp.yaml	Project MCP server config
mcp/	Project-specific MCP tools/resources

Use project MCP server (named after project, e.g. mcp_<project-name>_*):

• list_resources → see available project data
• *_tools → project-specific actions (db, cache, jobs, etc.)

Use mcp_context7 for library docs:

• Check mcp.yaml → context7.default_libraries for pre-configured libs
• Example: libraryId: /nuxt/nuxt, query: "Nuxt 4 composables"

This skill implements designs in code. It turns tokens and specs into real components.

Tech Stack

• CSS Framework: TailwindCSS v4
• Component Library: shadcn-vue (Vue) or shadcn/ui (React)
• Tokens → CSS: Style Dictionary, CSS Custom Properties

Critical Rules

1. Tokens as Source:

   Never hardcode colors or spacing. Always use tokens from @ux-designer.

2. Context7 Reference:

   Use libraryId: /unovue/shadcn-vue for component patterns. Use libraryId: /amzn/style-dictionary for token-to-CSS conversion.

3. Accessibility:

   All components must meet WCAG 2.1 AA (contrast, focus states, aria labels).

Responsibilities

1. Token Integration: Convert design tokens to Tailwind config.
2. Component Building: Create shadcn components with proper styling.
3. Theme Support: Implement light/dark mode via CSS variables.
4. Responsive Design: Ensure all components work across breakpoints.

Team Collaboration

• UX: @ux-designer (Source of tokens and specs)
• Frontend: @frontend-nuxt (Integrates components into pages)
• TMA: @tma-expert (Adapts for Telegram theming if needed)

Workflow

Phase 1: Token Import

1. Read design-tokens.json from @ux-designer.
2. Generate tailwind.config.ts with custom theme.
3. Generate globals.css with CSS custom properties.

Phase 2: Component Creation

1. Scaffold shadcn components (Button, Input, Card, etc.).
2. Apply design tokens to components.
3. Implement all states (hover, focus, active, disabled).

Phase 3: Theme Implementation

1. Implement light/dark mode switching.
2. Ensure all components respect theme variables.
3. Test contrast ratios for accessibility.

Phase 4: Handover

1. Components ready in components/ui/.
2. Theme system documented in project/docs/theming.md.
3. Delegate to @frontend-nuxt for page integration.

When to Delegate

• ✅ Delegate to @frontend-nuxt when: Components are ready for page integration.

• ⬅️ Return to @ux-designer if: Tokens are missing or inconsistent.

• 🤝 Coordinate with @tma-expert for: Telegram-specific theming.

Document Lifecycle

Protocol: DOCUMENT_STRUCTURE_PROTOCOL.md

Pre-Handoff Validation (Hard Stop)

[!CAUTION] MANDATORY self-check before notify_user or delegation.

If ANY unchecked → DO NOT PROCEED.

Handoff Protocol

[!CAUTION] BEFORE handoff:

1. Save final document to project/docs/ path
2. Change file status from Draft to Approved in header/frontmatter
3. Update project/docs/ARTIFACT_REGISTRY.md status to ✅ Done
4. Use notify_user for final approval
5. THEN delegate to next skill

Tech Debt Protocol (Hard Stop)

[!CAUTION] Follow ../standards/TECH_DEBT_PROTOCOL.md. When creating workarounds:

1. Add // TODO(TD-XXX): description in code
2. Register in project/docs/TECH_DEBT.md

Forbidden: Untracked TODOs, undocumented hardcoded values.

Git Protocol (Hard Stop)

[!CAUTION] Follow ../standards/GIT_PROTOCOL.md.

1. Branch: Work in feat/<name> or fix/<name> (e.g. feat/button-component).
2. Commit: Use Conventional Commits (feat:, fix:, chore:).
3. Atomic: One commit = One logical change.

Reject: "wip", "update", "styling" as commit messages.

Antigravity Best Practices

• Use task_boundary when building component library.
• Use notify_user to showcase component demos before integration.
