## [3.2.0] - 2025-10-02

### 🔄 Test-Fix Workflow & Agent Architecture Simplification

This release simplifies the agent architecture and introduces an automated test-fix workflow based on the principle "Tests Are the Review".

#### Added

**New Agent: test-fix-agent**:
- **Purpose**: Execute tests, diagnose failures, and fix code until all tests pass
- **Philosophy**: When all tests pass, code is automatically approved (no separate review needed)
- **Responsibilities**:
  - Execute complete test suite for implemented modules
  - Parse test output and identify failures
  - Diagnose root cause of test failures
  - Modify source code to fix issues
  - Re-run tests to verify fixes
  - Certify code approval when all tests pass

**Enhanced test-gen Command**:
- Transforms from planning tool to workflow orchestrator
- Auto-generates TEST-FIX tasks for test-fix-agent
- Automatically executes test validation via `/workflow:execute`
- Eliminates manual planning document generation

**New Task Types**:
- `test-gen`: Test generation tasks (handled by @code-developer)
- `test-fix`: Test execution and fixing tasks (handled by @test-fix-agent)

#### Changed

**Agent Architecture Simplification**:
- **Removed**: `@code-review-agent` and `@code-review-test-agent`
  - Testing now serves as the quality gate
  - Passing tests = approved code
- **Enhanced**: `@code-developer` now writes implementation + tests together
  - Unified generative work (code + tests)
  - Maintains context continuity
- **Added**: `@general-purpose` for optional manual reviews
  - Used only when explicitly requested
  - Handles special cases and edge scenarios

**Task Type Updates**:
- `"test"` → `"test-gen"` (clearer distinction from test-fix)
- Agent mapping updated across all commands:
  - `feature|bugfix|refactor|test-gen` → `@code-developer`
  - `test-fix` → `@test-fix-agent`
  - `review` → `@general-purpose` (optional)

**Workflow Changes**:
```
Old: code-developer → test-agent → code-review-agent
New: code-developer (code+tests) → test-fix-agent (execute+fix) → ✅ approved
```

#### Removed

- `@code-review-agent` - Testing serves as quality gate
- `@code-review-test-agent` - Functionality split between code-developer and test-fix-agent
- Separate review step - Tests passing = code approved

## [3.1.0] - 2025-10-02

### 🧪 TDD Workflow Support

This release introduces comprehensive Test-Driven Development (TDD) workflow support with Red-Green-Refactor cycle enforcement.

#### Added

**TDD Workflow Commands**:
- **`/workflow:tdd-plan`**: 5-phase TDD planning orchestrator
  - Creates structured TDD workflow with TEST → IMPL → REFACTOR task chains
  - Enforces Red-Green-Refactor methodology through task dependencies
  - Supports both manual and agent modes (`--agent` flag)
  - Validates TDD structure (chains, dependencies, meta fields)
  - Outputs: `TDD_PLAN.md`, `IMPL_PLAN.md`, `TODO_LIST.md`

- **`/workflow:tdd-verify`**: 4-phase TDD compliance verification
  - Validates task chain structure (TEST-N.M → IMPL-N.M → REFACTOR-N.M)
  - Analyzes test coverage metrics (line, branch, function coverage)
  - Verifies Red-Green-Refactor cycle execution
  - Generates comprehensive compliance report with scoring (0-100)
  - Outputs: `TDD_COMPLIANCE_REPORT.md`

**TDD Tool Commands**:
- **`/workflow:tools:task-generate-tdd`**: TDD task chain generator
  - Uses Gemini AI to analyze requirements and create TDD breakdowns
  - Generates TEST, IMPL, REFACTOR tasks with proper dependencies
  - Creates task JSONs with `meta.tdd_phase` field ("red"/"green"/"refactor")
  - Assigns specialized agents (`@code-review-test-agent`, `@code-developer`)
  - Maximum 10 features (30 total tasks) per workflow

- **`/workflow:tools:tdd-coverage-analysis`**: Test coverage and cycle analysis
  - Extracts test files from TEST tasks
  - Runs test suite with coverage (supports npm, pytest, cargo, go test)
  - Parses coverage metrics (line, branch, function)
  - Verifies TDD cycle execution through task summaries
  - Outputs: `test-results.json`, `coverage-report.json`, `tdd-cycle-report.md`

**TDD Architecture**:
- **Task ID Format**: `TEST-N.M`, `IMPL-N.M`, `REFACTOR-N.M`
  - N = feature number (1-10)
  - M = sub-task number (1-N)

- **Dependency System**:
  - `IMPL-N.M` depends on `TEST-N.M`
  - `REFACTOR-N.M` depends on `IMPL-N.M`
  - Enforces execution order: Red → Green → Refactor

- **Meta Fields**:
  - `meta.tdd_phase`: "red" | "green" | "refactor"
  - `meta.agent`: "@code-review-test-agent" | "@code-developer"

**Compliance Scoring**:
```
Base Score: 100 points
Deductions:
- Missing TEST task: -30 points per feature
- Missing IMPL task: -30 points per feature
- Missing REFACTOR task: -10 points per feature
- Wrong dependency: -15 points per error
- Wrong agent: -5 points per error
- Wrong tdd_phase: -5 points per error
- Test didn't fail initially: -10 points per feature
- Tests didn't pass after IMPL: -20 points per feature
- Tests broke during REFACTOR: -15 points per feature
```

#### Changed

**Documentation Updates**:
