TDD Workflow Plan Command (/workflow:tdd-plan)

Coordinator Role

This command is a pure orchestrator: Execute 5 slash commands in sequence, parse outputs, pass context, and ensure complete TDD workflow creation.

Execution Modes:

• Manual Mode (default): Use /workflow:tools:task-generate-tdd
• Agent Mode (--agent): Use /workflow:tools:task-generate-tdd --agent

Core Rules

1. Start Immediately: First action is TodoWrite initialization, second action is Phase 1 execution
2. No Preliminary Analysis: Do not read files before Phase 1
3. Parse Every Output: Extract required data for next phase
4. Sequential Execution: Each phase depends on previous output
5. Complete All Phases: Do not return until Phase 7 completes (with concept verification)
6. TDD Context: All descriptions include "TDD:" prefix
7. Quality Gate: Phase 5 concept verification ensures clarity before task generation

7-Phase Execution (with Concept Verification)

Phase 1: Session Discovery

Command: /workflow:session:start --auto "TDD: [structured-description]"

TDD Structured Format:

TDD: [Feature Name]
GOAL: [Objective]
SCOPE: [Included/excluded]
CONTEXT: [Background]
TEST_FOCUS: [Test scenarios]

Parse: Extract sessionId

Phase 2: Context Gathering

Command: /workflow:tools:context-gather --session [sessionId] "TDD: [structured-description]"

Parse: Extract contextPath

Phase 3: Test Coverage Analysis

Command: /workflow:tools:test-context-gather --session [sessionId]

Purpose: Analyze existing codebase for:

• Existing test patterns and conventions
• Current test coverage
• Related components and integration points
• Test framework detection

Parse: Extract testContextPath (.workflow/[sessionId]/.process/test-context-package.json)

Benefits:

• Makes TDD aware of existing environment
• Identifies reusable test patterns
• Prevents duplicate test creation
• Enables integration with existing tests

Phase 4: TDD Analysis

Command: /workflow:tools:concept-enhanced --session [sessionId] --context [contextPath]

Note: Generates ANALYSIS_RESULTS.md with TDD-specific structure:

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

Parse: Verify ANALYSIS_RESULTS.md contains TDD breakdown sections

Phase 5: Concept Verification (NEW QUALITY GATE)

Command: /workflow:concept-verify --session [sessionId]

Purpose: Verify conceptual clarity before TDD task generation

• Clarify test requirements and acceptance criteria
• Resolve ambiguities in expected behavior
• Validate TDD approach is appropriate

Behavior:

• If no ambiguities found → Auto-proceed to Phase 6
• If ambiguities exist → Interactive clarification (up to 5 questions)
• After clarifications → Auto-proceed to Phase 6

Parse: Verify concept verification completed (check for clarifications section in ANALYSIS_RESULTS.md or synthesis file if exists)

Phase 6: TDD Task Generation

Command:

• Manual: /workflow:tools:task-generate-tdd --session [sessionId]
• Agent: /workflow:tools:task-generate-tdd --session [sessionId] --agent

Parse: Extract feature count, chain count, task count

Validate:

• IMPL_PLAN.md exists (unified plan with TDD Task Chains section)
• TEST-.json, IMPL-.json, REFACTOR-*.json exist
• TODO_LIST.md exists
• IMPL tasks include test-fix-cycle configuration
• IMPL_PLAN.md contains workflow_type: "tdd" in frontmatter

Phase 7: TDD Structure Validation & Action Plan Verification (RECOMMENDED)

Internal validation first, then recommend external verification

Internal Validation:

1. Each feature has TEST → IMPL → REFACTOR chain
2. Dependencies: IMPL depends_on TEST, REFACTOR depends_on IMPL
3. Meta fields: tdd_phase correct ("red"/"green"/"refactor")
4. Agents: TEST uses @code-review-test-agent, IMPL/REFACTOR use @code-developer
5. IMPL tasks contain test-fix-cycle in flow_control for iterative Green phase

Return Summary:

TDD Planning complete for session: [sessionId]

Features analyzed: [N]
TDD chains generated: [N]
Total tasks: [3N]

Structure:
- Feature 1: TEST-1.1 → IMPL-1.1 → REFACTOR-1.1
[...]

Plan:
- Unified Implementation Plan: .workflow/[sessionId]/IMPL_PLAN.md
  (includes TDD Task Chains section with workflow_type: "tdd")

✅ Recommended Next Steps:
1. /workflow:action-plan-verify --session [sessionId]  # Verify TDD plan quality
2. /workflow:execute --session [sessionId]  # Start TDD execution
3. /workflow:tdd-verify [sessionId]  # Post-execution TDD compliance check

⚠️ Quality Gate: Consider running /workflow:action-plan-verify to validate TDD task dependencies

// Update after each phase: mark current "completed", next "in_progress"

Input Processing

Convert user input to TDD-structured format:

Simple text → Add TDD context Detailed text → Extract components with TEST_FOCUS File/Issue → Read and structure with TDD

Error Handling

• Parsing failure: Retry once, then report
• Validation failure: Report missing/invalid data
• Command failure: Keep phase in_progress, report error
• TDD validation failure: Report incomplete chains or wrong dependencies

TDD Workflow Enhancements

Overview

The TDD workflow has been significantly enhanced by integrating best practices from both traditional plan --agent and test-gen workflows, creating a hybrid approach that bridges the gap between idealized TDD and real-world development complexity.

Key Improvements

1. Test Coverage Analysis (Phase 3)

Adopted from test-gen workflow

Before planning TDD tasks, the workflow now analyzes the existing codebase:

• Detects existing test patterns and conventions
• Identifies current test coverage
• Discovers related components and integration points
• Detects test framework automatically

Benefits:

• Context-aware TDD planning
• Avoids duplicate test creation
• Enables integration with existing tests
• No longer assumes greenfield scenarios

2. Iterative Green Phase with Test-Fix Cycle

Adopted from test-gen workflow

IMPL (Green phase) tasks now include automatic test-fix cycle for resilient implementation:

Enhanced IMPL Task Flow:

1. Write minimal implementation code
2. Execute test suite
3. IF tests pass → Complete task ✅
4. IF tests fail → Enter fix cycle:
   a. Gemini diagnoses with bug-fix template
   b. Apply fix (manual or Codex)
   c. Retest
   d. Repeat (max 3 iterations)
5. IF max iterations → Auto-revert changes 🔄

Benefits:

• ✅ Faster feedback within Green phase
• ✅ Autonomous recovery from implementation errors
• ✅ Systematic debugging with Gemini
• ✅ Safe rollback prevents broken state

3. Agent-Driven Planning

From plan --agent workflow

Supports action-planning-agent for more autonomous TDD planning with:

• MCP tool integration (code-index, exa)
• Memory-first principles
• Brainstorming artifact integration
• Task merging over decomposition

Workflow Comparison

Aspect	Previous	Current
Phases	5	6 (test coverage analysis)
Context	Greenfield assumption	Existing codebase aware
Green Phase	Single implementation	Iterative with fix cycle
Failure Handling	Manual intervention	Auto-diagnose + fix + revert
Test Analysis	None	Deep coverage analysis
Feedback Loop	Post-execution	During Green phase

Migration Notes

Backward Compatibility: ✅ Fully compatible

• Existing TDD workflows continue to work
• New features are additive, not breaking
• Phase 3 can be skipped if test-context-gather not available
