Frontend Documentation Creator

L3 Worker that creates design_guidelines.md. CONDITIONAL - only invoked when project has frontend.

Purpose & Scope

• Creates design_guidelines.md (if hasFrontend)
• Receives Context Store from ln-110-project-docs-coordinator
• WCAG 2.1 Level AA accessibility compliance
• Design system documentation
• Never gathers context itself; uses coordinator input

Invocation (who/when)

• ln-110-project-docs-coordinator: CONDITIONALLY invoked when:
  • hasFrontend=true (react, vue, angular, svelte detected)
• Never called directly by users

Inputs

From coordinator:

• contextStore: Context Store with frontend-specific data
  • DESIGN_SYSTEM (Material-UI, Ant Design, custom)
  • COLOR_PALETTE (primary, secondary, accent)
  • TYPOGRAPHY (font families, sizes, weights)
  • COMPONENT_LIBRARY (detected components)
• targetDir: Project root directory
• flags: { hasFrontend }

Documents Created (1, conditional)

Workflow

Phase 1: Check Conditions

1. Parse flags from coordinator
2. If !hasFrontend: return early with empty result

Phase 2: Create Document

1. Check if file exists (idempotent)
2. If exists: skip with log
3. If not exists:
   • Copy template
   • Replace placeholders with Context Store values
   • Populate design system section
   • Mark [TBD: X] for missing data

Phase 3: Self-Validate

1. Check SCOPE tag
2. Validate sections:
   • Design System (component library)
   • Typography (font families, sizes)
   • Colors (hex codes, semantic colors)
3. Check WCAG 2.1 references
4. Check Maintenance section

Phase 4: Return Status

{
  "created": ["docs/project/design_guidelines.md"],
  "skipped": [],
  "tbd_count": 1,
  "validation": "OK"
}

Critical Notes

Core Rules

• Conditional: Skip entirely if no frontend detected
• WCAG compliance: Document must reference accessibility standards
• Design tokens: Extract from CSS variables, tailwind config, or theme files
• Idempotent: Never overwrite existing files

NO_CODE_EXAMPLES Rule (MANDATORY)

Design guidelines document visual standards, NOT code:

• FORBIDDEN: CSS code blocks, component implementations
• ALLOWED: Tables (colors, typography), design tokens, Figma links
• INSTEAD OF CODE: "See Component Library" or "See src/components/Button.tsx"

Stack Adaptation Rule (MANDATORY)

• Link to correct component library docs (MUI for React, Vuetify for Vue)
• Reference framework-specific patterns (React hooks, Vue composition API)
• Never mix stack references (no React examples in Vue project)

Format Priority (MANDATORY)

Tables (colors, typography, spacing) > Lists (component inventory) > Text

Definition of Done

• Condition checked (hasFrontend)
• Document created if applicable
• Design system, typography, colors documented
• WCAG references included
• Actuality verified: all document facts match current code (paths, functions, APIs, configs exist and are accurate)
• Status returned to coordinator
