TDD Task Generation Command

Overview

Generate TDD-specific task chains from analysis results with enforced Red-Green-Refactor structure and dependencies.

Core Philosophy

• TDD-First: Every feature starts with a failing test
• Chain-Enforced: Dependencies ensure proper TDD cycle
• Phase-Explicit: Each task marked with Red/Green/Refactor phase
• Artifact-Aware: Integrates brainstorming outputs
• Memory-First: Reuse loaded documents from memory
• Context-Aware: Analyzes existing codebase and test patterns
• Iterative Green Phase: Auto-diagnose and fix test failures with Gemini + optional Codex
• Safety-First: Auto-revert on max iterations to prevent broken state

Core Responsibilities

• Parse analysis results and identify testable features
• Generate Red-Green-Refactor task chains for each feature
• Enforce proper dependencies (TEST → IMPL → REFACTOR)
• Create TDD_PLAN.md and enhanced IMPL_PLAN.md
• Generate TODO_LIST.md with TDD phase indicators
• Update session state for TDD execution

Execution Lifecycle

Phase 1: Input Validation & Discovery

⚡ Memory-First Rule: Skip file loading if documents already in conversation memory

1. Session Validation

   • If session metadata in memory → Skip loading
   • Else: Load .workflow/{session_id}/workflow-session.json

2. Analysis Results Loading

   • If ANALYSIS_RESULTS.md in memory → Skip loading
   • Else: Read .workflow/{session_id}/.process/ANALYSIS_RESULTS.md

3. Artifact Discovery

   • If artifact inventory in memory → Skip scanning
   • Else: Scan .workflow/{session_id}/.brainstorming/ directory
   • Detect: synthesis-specification.md, topic-framework.md, role analyses

Phase 2: TDD Task JSON Generation

Input: Use .process/ANALYSIS_RESULTS.md directly (enhanced with TDD structure from concept-enhanced phase)

Note: The ANALYSIS_RESULTS.md now includes TDD-specific breakdown:

• Feature list with testable requirements
• Test cases for Red phase
• Implementation requirements for Green phase
• Refactoring opportunities
• Task dependencies and execution order

Phase 3: Enhanced IMPL_PLAN.md Generation

Task Chain Structure

For each feature, generate 3 tasks with ID format:

• TEST-N.M (Red phase)
• IMPL-N.M (Green phase)
• REFACTOR-N.M (Refactor phase)

Chain Dependency Rules

• IMPL depends_on TEST: Cannot implement before test exists
• REFACTOR depends_on IMPL: Cannot refactor before implementation
• Cross-feature dependencies: If Feature 2 needs Feature 1, then IMPL-2.1 depends_on ["REFACTOR-1.1"]

Agent Assignment

• TEST tasks → @code-review-test-agent
• IMPL tasks → @code-developer
• REFACTOR tasks → @code-developer

Meta Fields

• meta.type: "test" | "feature" | "refactor"
• meta.agent: Agent for task execution
• meta.tdd_phase: "red" | "green" | "refactor"

## 3. Brainstorming Artifacts Reference

### Artifact Usage Strategy
**Primary Reference (synthesis-specification.md)**:
- **What**: Comprehensive implementation blueprint from multi-role synthesis
- **When**: Every TDD task (TEST/IMPL/REFACTOR) references this for requirements and acceptance criteria
- **How**: Extract testable requirements, architecture decisions, expected behaviors
- **Priority**: Authoritative - defines what to test and how to implement
- **CCW Value**: Consolidates insights from all brainstorming roles into single source of truth for TDD

**Context Intelligence (context-package.json & test-context-package.json)**:
- **What**: Smart context from CCW's context-gather and test-context-gather phases
- **Content**: Focus paths, dependency graph, existing test patterns, test framework configuration
- **Usage**: RED phase loads test patterns, GREEN phase loads implementation context
- **CCW Value**: Automated discovery of existing tests and patterns for TDD consistency

**Technical Analysis (ANALYSIS_RESULTS.md)**:
- **What**: Gemini/Qwen parallel analysis with TDD-specific breakdown
- **Content**: Testable requirements, test scenarios, implementation strategies, risk assessment
- **Usage**: RED phase references test cases, GREEN phase references implementation approach
- **CCW Value**: Multi-model analysis providing comprehensive TDD guidance

### Integrated Specifications (Highest Priority)
- **synthesis-specification.md**: Comprehensive implementation blueprint
  - Contains: Architecture design, functional/non-functional requirements

### Supporting Artifacts (Reference)
- **topic-framework.md**: Discussion framework
- **system-architect/analysis.md**: Architecture specifications
- **Role-specific analyses**: [Other relevant analyses]

**Artifact Priority in Development**:
1. synthesis-specification.md (primary reference for test cases and implementation)
2. test-context-package.json (existing test patterns for TDD consistency)
3. context-package.json (smart context for execution environment)
4. ANALYSIS_RESULTS.md (technical analysis with TDD breakdown)
5. Role-specific analyses (supplementary)

## 4. Implementation Strategy

### Execution Strategy
**Execution Model**: TDD Cycles (Red-Green-Refactor)

**Rationale**: Test-first approach ensures correctness and reduces bugs

**TDD Cycle Pattern**:
- RED: Write failing test
- GREEN: Implement minimal code to pass (with test-fix cycle if needed)
- REFACTOR: Improve code quality while keeping tests green

**Parallelization Opportunities**:
- [Independent features that can be developed in parallel]

### Architectural Approach
**Key Architecture Decisions**:
- [ADR references from synthesis]
- [TDD-compatible architecture patterns]

**Integration Strategy**:
- [How modules communicate]
- [Test isolation strategy]

### Key Dependencies
**Task Dependency Graph**:

Feature 1: TEST-1.1 (RED) ↓ IMPL-1.1 (GREEN) [with test-fix cycle] ↓ REFACTOR-1.1 (REFACTOR)

Feature 2: TEST-2.1 (RED) [depends on REFACTOR-1.1 if related] ↓ IMPL-2.1 (GREEN) ↓ REFACTOR-2.1 (REFACTOR)

**Critical Path**: [Identify bottleneck features]

### Testing Strategy
**TDD Testing Approach**:
- Unit testing: Each feature has comprehensive unit tests
- Integration testing: Cross-feature integration
- E2E testing: Critical user flows after all TDD cycles

**Coverage Targets**:
- Lines: ≥80% (TDD ensures high coverage)
- Functions: ≥80%
- Branches: ≥75%

**Quality Gates**:
- All tests must pass before moving to next phase
- Refactor phase must maintain test success

## 5. TDD Task Chains (TDD-Specific Section)

### Feature-by-Feature TDD Chains

**Feature 1: {Feature Name}**

🔴 TEST-1.1: Write failing test for {feature} ↓ 🟢 IMPL-1.1: Implement to pass tests (includes test-fix cycle: max 3 iterations) ↓ 🔵 REFACTOR-1.1: Refactor implementation while keeping tests green

**Feature 2: {Feature Name}**

🔴 TEST-2.1: Write failing test for {feature} ↓ 🟢 IMPL-2.1: Implement to pass tests (includes test-fix cycle) ↓ 🔵 REFACTOR-2.1: Refactor implementation

[Continue for all N features]

### TDD Task Breakdown Summary
- **Total Features**: {N}
- **Total Tasks**: {3N} (N TEST + N IMPL + N REFACTOR)
- **TDD Chains**: {N}

## 6. Implementation Plan (Detailed Phased Breakdown)

### Execution Strategy

**TDD Cycle Execution**: Feature-by-feature sequential TDD cycles

**Phase 1 (Weeks 1-2): Foundation Features**
- **Features**: Feature 1, Feature 2
- **Tasks**: TEST-1.1, IMPL-1.1, REFACTOR-1.1, TEST-2.1, IMPL-2.1, REFACTOR-2.1
- **Deliverables**:

## 7. Risk Assessment & Mitigation

| Risk | Impact | Probability | Mitigation Strategy | Owner |
|------|--------|-------------|---------------------|-------|
| Tests fail repeatedly in GREEN phase | High | Medium | Test-fix cycle (max 3 iterations) with auto-revert | Dev Team |
| Complex features hard to test | High | Medium | Break down into smaller testable units | Architect |
| [Other risks] | Med/Low | Med/Low | [Strategies] | [Owner] |

**Critical Risks** (TDD-Specific):
- **GREEN phase failures**: Mitigated by test-fix cycle with Gemini diagnosis
- **Test coverage gaps**: Mitigated by TDD-first approach ensuring tests before code

**Monitoring Strategy**:
- Track TDD cycle completion rate
- Monitor test success rate per iteration

## 8. Success Criteria

- [ ] All features implemented through TDD cycles
- [ ] All RED-GREEN-REFACTOR cycles completed successfully

**Technical Quality**:
- [ ] Test coverage ≥80% (ensured by TDD)
- [ ] All tests passing (GREEN state achieved)
- [ ] Code refactored for quality (REFACTOR phase completed)

**Operational Readiness**:

- [ ] Test failure alerting configured

**TDD Compliance**:
- [ ] Every feature has TEST → IMPL → REFACTOR chain
- [ ] No implementation without tests (RED-first principle)
- [ ] Refactoring did not break tests

Phase 5: TODO_LIST.md Generation

Generate task list with TDD phase indicators:

- [ ] **REFACTOR-1.1**: Refactor implementation (🔵 REFACTOR) [depends: IMPL-1.1] → [📋](./.task/REFACTOR-1.1.json)

Phase 6: Session State Update

Update workflow-session.json with TDD metadata:

{
  "workflow_type": "tdd",
  "feature_count": 10,
  "task_count": 30,
  "tdd_chains": 10
}

Next: /workflow:execute or /workflow:tdd-verify

Test Coverage Analysis Integration

The TDD workflow includes test coverage analysis (via /workflow:tools:test-context-gather) to:

• Detect existing test patterns and conventions
• Identify current test coverage gaps
• Discover test framework and configuration
• Enable integration with existing tests

This makes TDD workflow context-aware instead of assuming greenfield scenarios.

Iterative Green Phase with Test-Fix Cycle

IMPL (Green phase) tasks include automatic test-fix cycle:

Process Flow:

1. Initial Implementation: Write minimal code to pass tests
2. Test Execution: Run test suite
3. Success Path: Tests pass → Complete task
4. Failure Path: Tests fail → Enter iterative fix cycle:
   • Gemini Diagnosis: Analyze failures with bug-fix template
   • Fix Application: Manual (default) or Codex (if meta.use_codex=true)
   • Retest: Verify fix resolves failures
   • Repeat: Up to max_iterations (default: 3)
5. Safety Net: Auto-revert all changes if max iterations reached

Key Benefits:

• ✅ Faster feedback loop within Green phase
• ✅ Autonomous recovery from initial implementation errors
• ✅ Systematic debugging with Gemini's bug-fix template
• ✅ Safe rollback prevents broken TDD state

Configuration Options

• meta.max_iterations: Number of fix attempts (default: 3 for TDD, 5 for test-gen)
• meta.use_codex: Enable Codex automated fixes (default: false, manual)
