workflow-tdd-plan

Auto Mode

When --yes or -y: Skip all confirmations, use defaults, auto-verify. This skill is planning-only — it NEVER executes implementation. Output is the plan for user review.

Workflow TDD Plan

Usage

# Plan mode (default)
$workflow-tdd-plan "Build authentication system with JWT and OAuth"
$workflow-tdd-plan -y "Add rate limiting to API endpoints"
$workflow-tdd-plan --session WFS-auth "Extend with 2FA support"

# Verify mode
$workflow-tdd-plan verify --session WFS-auth
$workflow-tdd-plan verify

Flags:

• -y, --yes: Skip all confirmations (auto mode)
• --session ID: Use specific session

---

Overview

Multi-mode TDD planning pipeline using subagent coordination. Plan mode runs 6 sequential phases with conditional branching; verify mode operates on existing plans with TDD compliance validation.

Core Principle: NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST

Implementation

Session Initialization

const getUtc8ISOString = () => new Date(Date.now() + 8 * 60 * 60 * 1000).toISOString()

// Parse flags
const AUTO_YES = $ARGUMENTS.includes('--yes') || $ARGUMENTS.includes('-y')

let mode = 'plan'

  .replace(/^["']|["']$/g, '')
  .trim()

// Convert to TDD structured format
function toTddStructured(desc) {

  return `TDD: ${featureName}
GOAL: ${desc}
SCOPE: Core implementation
CONTEXT: New development
TEST_FOCUS: Unit tests, integration tests, edge cases`
}

const structuredDesc = toTddStructured(taskDescription)

Phase 1: Session Discovery (Plan Mode)

Objective: Create or find workflow session, initialize planning notes with TDD context.

if (mode !== 'plan') {
  // verify: locate existing session
  // → Jump to Phase 7
}

let sessionId, sessionFolder

if (existingSessionId) {
  sessionId = existingSessionId
  sessionFolder = `.workflow/active/${sessionId}`
  if (!Bash(`test -d "${sessionFolder}" && echo yes`).trim()) {
    console.log(`ERROR: Session ${sessionId} not found`)
    return
  }
} else {
  // Auto-detect from .workflow/active/ or create new
  const sessions = Bash(`ls -d .workflow/active/WFS-* 2>/dev/null`).trim().split('\n').filter(Boolean)

  if (sessions.length === 0 || taskDescription) {
    // Create new session
    const slug = taskDescription.toLowerCase()
      .replace(/[^a-z0-9\u4e00-\u9fa5]+/g, '-').substring(0, 40)
    sessionId = `WFS-${slug}`
    sessionFolder = `.workflow/active/${sessionId}`
    Bash(`mkdir -p "${sessionFolder}/.task" "${sessionFolder}/.process"`)

    Write(`${sessionFolder}/workflow-session.json`, JSON.stringify({
      session_id: sessionId,
      status: 'planning',
      workflow_type: 'tdd',
      created_at: getUtc8ISOString(),
      task_description: taskDescription
    }, null, 2))
  } else if (sessions.length === 1) {
    sessionId = sessions[0].split('/').pop()
    sessionFolder = sessions[0]
  } else {
    // Multiple sessions — ask user

    } else {
      const answer = request_user_input({

          header: "Session",

// Initialize planning-notes.md with TDD context
Write(`${sessionFolder}/planning-notes.md`, `# TDD Planning Notes

## User Intent
${structuredDesc}

## TDD Principles
- NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST
- Red-Green-Refactor cycle for all tasks
- Test-first forces edge case discovery before implementation

console.log(`Session: ${sessionId}`)

Phase 2: Context Gathering (spawn_agent)

Objective: Gather project context, assess conflict risk.

console.log(`\n## Phase 2: Context Gathering\n`)

const ctxAgent = spawn_agent({
  agent_type: "context_search_agent",
  instruction: `
Gather implementation context for TDD planning.

**Session**: ${sessionFolder}
**Task**: ${taskDescription}
**Mode**: TDD_PLAN

### Steps
1. Analyze project structure (package.json, tsconfig, etc.)
2. Search for existing similar implementations
3. Identify integration points and dependencies
4. Assess conflict risk with existing code
5. Generate context package

### Output
Write context package to: ${sessionFolder}/.process/context-package.json
Format: {
  "critical_files": [...],
  "patterns": [...],
  "dependencies": [...],
  "integration_points": [...],
  "conflict_risk": "none" | "low" | "medium" | "high",
  "conflict_areas": [...],
  "constraints": [...]
}
`
})

wait({ id: ctxAgent })
close_agent({ id: ctxAgent })

// Parse outputs
const contextPkg = JSON.parse(Read(`${sessionFolder}/.process/context-package.json`) || '{}')
const conflictRisk = contextPkg.conflict_ris
