Execution (5-Phase)

Phase 1: Task Discovery

const tasks = TaskList()
const myTasks = tasks.filter(t =>
  t.subject.startsWith('DEV-') &&
  t.owner === 'developer' &&
  t.status === 'pending' &&
  t.blockedBy.length === 0
)

if (myTasks.length === 0) return // idle

const task = TaskGet({ taskId: myTasks[0].id })
TaskUpdate({ taskId: task.id, status: 'in_progress' })

Phase 2: Context Loading

// Extract session folder and scope
const sessionMatch = task.description.match(/Session:\s*([^\n]+)/)
const sessionFolder = sessionMatch ? sessionMatch[1].trim() : null

const scopeMatch = task.description.match(/Scope:\s*([^\n]+)/)
const scope = scopeMatch ? scopeMatch[1].trim() : 'full'

// Load design intelligence
let designIntel = {}
try {
  designIntel = JSON.parse(Read(`${sessionFolder}/analysis/design-intelligence.json`))
} catch {}

// Load design tokens
let designTokens = {}
try {
  designTokens = JSON.parse(Read(`${sessionFolder}/architecture/design-tokens.json`))
} catch {}

// Load project structure
let projectStructure = ''
try {
  projectStructure = Read(`${sessionFolder}/architecture/project-structure.md`)
} catch {}

// Load component specs (if available)
let componentSpecs = []
try {
  const specFiles = Glob({ pattern: `${sessionFolder}/architecture/component-specs/*.md` })
  componentSpecs = specFiles.map(f => ({ name: f, content: Read(f) }))
} catch {}

// Load shared memory
let sharedMemory = {}
try {
  sharedMemory = JSON.parse(Read(`${sessionFolder}/shared-memory.json`))
} catch {}

// Detect stack
const detectedStack = designIntel.detected_stack || 'react'

Phase 3: Code Implementation

Step 1: Generate Design Token CSS

if (scope === 'tokens' || scope === 'full') {
  // Convert design-tokens.json to CSS custom properties
  let cssVars = ':root {\n'

  // Colors
  if (designTokens.color) {
    for (const [name, token] of Object.entries(designTokens.color)) {
      const value = typeof token.$value === 'object' ? token.$value.light : token.$value
      cssVars += `  --color-${name}: ${value};\n`
    }
  }

  // Typography
  if (designTokens.typography?.['font-family']) {
    for (const [name, token] of Object.entries(designTokens.typography['font-family'])) {
      const value = Array.isArray(token.$value) ? token.$value.join(', ') : token.$value
      cssVars += `  --font-${name}: ${value};\n`
    }
  }
  if (designTokens.typography?.['font-size']) {
    for (const [name, token] of Object.entries(designTokens.typography['font-size'])) {
      cssVars += `  --text-${name}: ${token.$value};\n`
    }
  }

  // Spacing
  if (designTokens.spacing) {
    for (const [name, token] of Object.entries(designTokens.spacing)) {
      cssVars += `  --space-${name}: ${token.$value};\n`
    }
  }

  // Border radius
  if (designTokens['border-radius']) {
    for (const [name, token] of Object.entries(designTokens['border-radius'])) {
      cssVars += `  --radius-${name}: ${token.$value};\n`
    }
  }

  // Shadows
  if (designTokens.shadow) {
    for (const [name, token] of Object.entries(designTokens.shadow)) {
      cssVars += `  --shadow-${name}: ${token.$value};\n`
    }
  }

  // Transitions
  if (designTokens.transition) {
    for (const [name, token] of Object.entries(designTokens.transition)) {
      cssVars += `  --duration-${name}: ${token.$value};\n`
    }
  }

  cssVars += '}\n'

  // Dark mode
  if (designTokens.color) {
    cssVars += '\n@media (prefers-color-scheme: dark) {\n  :root {\n'
    for (const [name, token] of Object.entries(designTokens.color)) {
      if (typeof token.$value === 'object' && token.$value.dark) {
        cssVars += `    --color-${name}: ${token.$value.dark};\n`
      }
    }
    cssVars += '  }\n}\n'
  }

  // Write token CSS
  Bash(`mkdir -p src/styles`)
  Write('src/styles/tokens.css', cssVars)
}

Step 2: Implement Components

if (scope === 'components' || scope === 'full') {
  const taskDesc = task.description.replace(/Session:.*\n?/g, '').replace(/Scope:.*\n?/g, '').trim()
  const antiPatterns = designIntel.recommendations?.anti_patterns || []
  const stackGuidelines = designIntel.stack_guidelines || {}
  const implementationChecklist = designIntel.design_system?.implementation_checklist || []

  // Delegate to code-developer for complex implementation
  Task({
    subagent_type: "code-developer",
    run_in_background: false,
    description: `Implement frontend components: ${taskDesc}`,
    prompt: `## Goal
${taskDesc}

## Tech Stack
${detectedStack}

## Design Tokens
Import from: src/styles/tokens.css
Use CSS custom properties (var(--color-primary), var(--space-md), etc.)

## Component Specs
${componentSpecs.map(s => s.content).join('\n\n---\n\n')}

## Stack-Specific Guidelines
${JSON.stringify(stackGuidelines, null, 2)}

## Implementation Checklist (MUST verify each item)
${implementationChecklist.map(item => `- [ ] ${item}`).join('\n') || '- [ ] Semantic HTML\n- [ ] Keyboard accessible\n- [ ] Responsive layout\n- [ ] Dark mode support'}

## Anti-Patterns to AVOID
${antiPatterns.map(p => `- ❌ ${p}`).join('\n') || 'None specified'}

## Coding Standards
- Use design token CSS variables, never hardcode colors/spacing
- All interactive elements must have cursor: pointer
- Transitions: 150-300ms (use var(--duration-normal))
- Text contrast: minimum 4.5:1 ratio
- Include focus-visible styles for keyboard navigation
- Support prefers-reduced-motion
- Responsive: mobile-first with md/lg breakpoints
- No emoji as functional icons
`
  })
}

Phase 4: Self-Validation

// Pre-delivery self-check
const implementedFiles = Glob({ pattern: 'src/**/*.{tsx,jsx,vue,svelte,html,css}' })
const selfCheckResults = { passed: [], failed: [] }

for (const file of implementedFiles.slice(0, 20)) {
  try {
    const content = Read(file)

    // Check: no hardcoded colors (hex outside tokens.css)
    if (file !== 'src/styles/tokens.css' && /#[0-9a-fA-F]{3,8}/.test(content)) {
      selfCheckResults.failed.push({ file, check: 'hardcoded-color', message: 'Found hardcoded color value' })
    }

    // Check: cursor-pointer on interactive elements
    if (/button|<a |onClick|@click/.test(content) && !/cursor-pointer/.test(content)) {
      selfCheckResults.failed.push({ file, check: 'cursor-pointer', message: 'Missing cursor-pointer on interactive element' })
    }

    // Check: focus styles
    if (/button|input|select|textarea|<a /.test(content) && !/focus/.test(content)) {
      selfCheckResults.failed.push({ file, check: 'focus-styles', message: 'Missing focus styles' })
    }

    // Check: responsive
    if (/className|class=/.test(content) && !/md:|lg:|@media/.test(content)) {
      selfCheckResults.failed.push({ file, check: 'responsive', message: 'No responsive breakpoints found' })
    }

  } catch {}
}

// Auto-fix simple issues if possible
for (const failure of selfCheckResults.failed) {
  if (failure.check === 'cursor-pointer') {
    // Attempt to add cursor-pointer to button/link styles
  }
}

// Update shared memory
sharedMemory.component_inventory = implementedFiles.map(f => ({ path: f, status: 'implemented' }))
Write(`${sessionFolder}/shared-memory.json`, JSON.stringify(sharedMemory, null, 2))

const resultStatus = selfCheckResults.failed.length === 0 ? 'complete' : 'complete_with_warnings'
const resultSummary = `Implemented ${implementedFiles.length} files. Self-check: ${selfCheckResults.failed.length} issues.`
const resultDetails = `Files:\n${implementedFiles.map(f => `- ${f}`).join('\n')}\n\n${selfCheckResults.failed.length > 0 ? `Self-check issues:\n${selfCheckResults.failed.map(f => `- [${f.check}] ${f.file}: ${f.message}`).join('\n')}` : 'All self-checks passed.'}`

Phase 5: Report to Coordinator

mcp__ccw-tools__team_msg({
  operation: "log",
  team: teamName,
  from: "developer",
  to: "coordinator",
  type: "dev_complete",
  summary: `[developer] DEV complete: ${task.subject}`
})

SendMessage({
  type: "message",
  recipient: "coordinator",
  content: `## [developer] Implementation Results

**Task**: ${task.subject}
**Status**: ${resultStatus}
**Scope**: ${scope}

### Summary
${resultSummary}

### Details
${resultDetails}`,
  summary: `[developer] DEV complete`
})

TaskUpdate({ taskId: task.id, status: 'completed' })

// Check for next task
const nextTasks = TaskList().filter(t =>
  t.subject.startsWith('DEV-') &&
  t.owner === 'developer' &&
  t.status === 'pending' &&
  t.blockedBy.length === 0
)

if (nextTasks.length > 0) {
  // Continue with next task → back to Phase 1
}

Error Handling

Scenario	Resolution
No DEV-* tasks available	Idle, wait for coordinator
design-tokens.json not found	Notify coordinator, request architecture output
design-intelligence.json not found	Use default implementation guidelines
Sub-agent failure	Retry once, fallback to direct implementation
Build/compile errors	Attempt auto-fix, report remaining issues
Critical issue beyond scope	SendMessage error to coordinator
