Source documentation, not instructions for this website. Review permissions before running any commands.

Cross-runtime: follow runtime compatibility for invocation, delegation, configuration precedence, state paths, and permissions.

You are helping implement a ticket using Test-Driven Development (TDD). Your task is to guide the user through the RED-GREEN-REFACTOR cycle: write failing tests first, implement code to pass tests, then refactor while keeping tests green.

Step 1: Load Configuration

Check for configuration and context:

# Check for config and context files
if [ -f ".git-workflow/config.yaml" ]; then
  CONFIG_PATH=".git-workflow/config.yaml"
elif [ -f ".claude/config.yaml" ]; then
  CONFIG_PATH=".claude/config.yaml" # legacy read-only fallback
else
  CONFIG_PATH=""
fi
if [ -f ".git-workflow/pr-context.json" ]; then
  CONTEXT_PATH=".git-workflow/pr-context.json"
elif [ -f ".claude/.pr-context.json" ]; then
  CONTEXT_PATH=".claude/.pr-context.json" # legacy read-only fallback
else
  CONTEXT_PATH=""
fi

Load from the resolved CONFIG_PATH (if one exists):

qa:
  tdd:
    confirmBeforeGreen: true
    confirmBeforeRefactor: true
    maxRedAttempts: 3
    runFullSuiteEachPhase: false
    autoStartServer: false
testing:
  unit: auto
  lint: auto
  typeCheck: auto
issueTracker:
  type: auto

Default Values (when no config):

qa:
  tdd:
    confirmBeforeGreen: true
    confirmBeforeRefactor: true
    maxRedAttempts: 3
    runFullSuiteEachPhase: false
    autoStartServer: false

Step 2: Parse Arguments

Extract from $ARGUMENTS:

$ARGUMENTS

Patterns to Extract:

Pattern	Example	Meaning
Ticket ID	`PROJ-123`, `ENG-456`	Issue tracker ticket
GitHub Issue	`#789`	GitHub issue number
Linear URL	`https://linear.app/.../ENG-456/...`	Extract ticket ID
Jira URL	`https://....atlassian.net/browse/PROJ-123`	Extract ticket ID

Parsing Logic:

Extract ticket ID from URL if provided
Linear: Pattern /issue/([A-Z]+-\d+)/
Jira: Pattern /browse/([A-Z]+-\d+)
GitHub: Pattern issues/(\d+) or #(\d+)

Validation:

Ticket ID is required for TDD workflow
If not provided, prompt the user for it

Step 3: Fetch Ticket Details

Auto-Detect Issue Tracker Type

Based on ticket format and available MCP servers:

^[A-Z]+-\d+$ with Linear MCP available -> Linear
^[A-Z]+-\d+$ with Jira config/MCP available -> Jira
^#?\d+$ or GitHub URL -> GitHub Issues (via gh CLI)

Linear Integration

If Linear ticket format is detected, use the Linear MCP server:

mcp__linear__get_issue(id: ticketId)

Extract:

Title
Description
Acceptance criteria
Labels (to determine bug vs feature)

Jira Integration

If Jira is configured, use the Jira MCP server:

mcp__jira__get_issue(issueKey: ticketId)

Extract:

Summary (title)
Description
Acceptance criteria
Issue type (Bug/Story/Task)

GitHub Issues

If GitHub format detected:

gh issue view {issue_number} --repo {owner}/{repo} --json title,body,labels

Determine Ticket Type

From ticket labels/type, determine:

Label/Type	Classification	TDD Behavior
`bug`, `Bug`, `defect`	Bug	Include reproduction step
`feature`, `Story`, `enhancement`	Feature	Skip reproduction
`refactor`, `tech-debt`	Refactor	Focus on existing tests first

Step 4: Explore Codebase

Gather context about the codebase:

Search for files related to the ticket:

# Search for keywords from ticket title/description
# Look for existing implementations
# Find related test files

Look for:

Files matching keywords from ticket
Existing test files in same area
Related service/controller files
Configuration files

Analyze Test Patterns

Identify existing test patterns:

# Find test files
find . -name "*.test.ts" -o -name "*.spec.ts" -o -name "*_test.py" -o -name "*_test.go" | head -20

# Check test framework imports
grep -r "describe\|it\|test\|expect" --include="*.test.*" -l | head -5

Extract:

Test file naming convention (*.test.ts, *.spec.ts, *_test.py, etc.)
Test framework (Jest, Vitest, pytest, go test, etc.)
Test structure (describe/it, test(), etc.)
Mock patterns used

Detect Test Framework

Full per-language detection commands, tables, and the detection-results JSON shape: see references/test-frameworks.md.

Step 5: Reproduce Issue (Bugs Only)

Skip this step for features and refactors.

For bugs, attempt to reproduce the issue:

Optional: Start Development Server

If qa.tdd.autoStartServer: true:

# Detect and start dev server (background)
npm run dev &
# or
pnpm dev &
# Wait for server to be ready
sleep 5

Manual Reproduction

Ask the user to confirm the bug reproduction:

Question: "Can you reproduce the bug? Describe the steps and current behavior."

Options:

Yes, I can reproduce it
No, let me try first
Skip reproduction (proceed to tests)

Document Expected vs Actual

If user reproduces:

{
  "reproduction": {
    "steps": ["Step 1", "Step 2"],
    "currentBehavior": "What happens now",
    "expectedBehavior": "What should happen"
  }
}

Step 6: TDD RED Phase - Write Failing Tests

Create Test File

If test file doesn't exist, create it following project conventions:

# Determine test file location
# Based on source file: src/services/auth.ts -> tests/services/auth.test.ts
# Or co-located: src/services/auth.ts -> src/services/auth.test.ts

Generate Test Cases

Based on ticket acceptance criteria, generate failing tests:

Sample generated test code for bugs and features: see references/examples.md.

Run Tests - Verify RED

# Run the specific test target (varies by framework)
{TEST_COMMAND} {TEST_FILE}

Per-language run commands (Go, Rust, etc.) and examples: see references/test-frameworks.md.

Expected: Tests should FAIL (RED phase)

Handle Unexpected Results

Result	Action
Tests fail (expected)	Proceed to GREEN phase
Tests pass	Warning: "Tests pass but shouldn't. Is the issue already fixed?"
Syntax errors	Fix test syntax, retry
Import errors	Fix imports, retry

If tests pass unexpectedly:

Question: "The tests pass, but we expected them to fail. What should we do?"

Options:

Issue is already fixed - verify and close
Tests are incorrect - adjust test assertions
Different test needed - rewrite tests
Proceed anyway

Max Attempts:

Track attempts (default: maxRedAttempts: 3). If max reached:

Question: "Failed to achieve RED phase after {N} attempts. How should we proceed?"

Options:

Continue trying with guidance
Skip to implementation
Abort TDD workflow

Step 7: TDD GREEN Phase - Implement Code

Confirmation (If Configured)

If qa.tdd.confirmBeforeGreen: true:

Question: "RED phase complete. Tests are failing as expected. Proceed to GREEN phase?"

Options:

Yes, implement the fix/feature
Review tests first
Add more tests before implementing

Implement Minimum Code

Write the minimum code necessary to make tests pass:

Guidelines:

Focus only on passing the tests
Don't add extra functionality
Don't optimize yet
Don't refactor yet

Run Tests - Verify GREEN

# Run tests again (use the same target as RED phase)
{TEST_COMMAND} {TEST_FILE}

Per-language run commands: see references/test-frameworks.md.

Expected: Tests should PASS (GREEN phase)

Handle Failures

If tests still fail:

Analyze error messages
Fix implementation
Re-run tests
Repeat until green

Track attempts. If struggling:

Question: "Tests are still failing. Need help troubleshooting?"

Options:

Show me the errors - I'll help debug
I'll fix it manually
Skip to refactor phase anyway

Optional: Run Full Suite

If qa.tdd.runFullSuiteEachPhase: true:

# Run full test suite
{TEST_COMMAND}

Ensure no regressions were introduced.

Step 8: TDD REFACTOR Phase - Clean Up

Confirmation (If Configured)

If qa.tdd.confirmBeforeRefactor: true:

Question: "GREEN phase complete. All tests pass. Proceed to REFACTOR phase?"

Options:

Yes, clean up the code
Skip refactoring - code is good enough
Add more tests first

Refactoring Guidelines

Review and improve the implementation:

Check for:

Code duplication
Long methods/functions
Poor naming
Missing error handling
Performance issues
Type safety

Do NOT:

Add new functionality
Change behavior
Break existing tests

Run Tests After Each Change

After each refactoring change:

{TEST_COMMAND} {TEST_FILE}

Per-language run commands: see references/test-frameworks.md.

Ensure tests remain GREEN throughout refactoring.

Step 9: Final Verification

Run Full Test Suite

# Run all tests
{FULL_TEST_COMMAND}

# Examples:
# npm test
# pnpm test
# pytest
# cargo test
# go test ./...

Run Linting

# Auto-detected or from config
{LINT_COMMAND}

# Examples:
# npm run lint
# pnpm lint
# ruff check .
# cargo clippy

Run Type Check (If Applicable)

# TypeScript
npx tsc --noEmit

# Python (mypy)
mypy .

Summary of Checks

Check	Status	Notes
New tests	PASS	{N} tests added
Full suite	PASS	{M} total tests
Linting	PASS	No issues
Type check	PASS	No errors

Step 10: Update Context

Update .git-workflow/pr-context.json with TDD information:

mkdir -p .git-workflow

Always write the canonical path. Never modify the legacy context fallback.

{
  "ticket_id": "PROJ-1234",
  "ticket_url": "https://...",
  "ticket_title": "Title from ticket",
  "branch": "fix/proj-1234-description",
  "type": "fix",
  "description": "Description",
  "started_at": "2025-01-17T12:00:00Z",
  "tdd": {
    "test_files": ["tests/auth/login.test.ts"],
    "implementation_files": ["src/services/auth.ts"],
    "tests_added": 2,
    "tests_modified": 0,
    "phases_completed": ["red", "green", "refactor"],
    "completed_at": "2025-01-17T14:30:00Z"
  }
}

This enables /commit to generate better commit messages and /finish to include TDD summary in PR description.

Step 11: Summary

Output a completion summary:

Sample completion summary format: see references/examples.md.

Configuration Reference

Full settings table: see references/configuration.md.

Error Handling

Full error-scenario table: see references/error-handling.md.

You are helping implement a ticket using Test-Driven Development (TDD). Your task is to guide the user through the RED-GREEN-REFACTOR cycle: write failing tests first, implement code to pass tests, then refactor while keeping tests green.

## Step 1: Load Configuration

Check for configuration and context:

```bash
# Check for config and context files
if [ -f ".git-workflow/config.yaml" ]; then
  CONFIG_PATH=".git-workflow/config.yaml"
elif [ -f ".claude/config.yaml" ]; then
  CONFIG_PATH=".claude/config.yaml" # legacy read-only fallback
else
  CONFIG_PATH=""
fi
if [ -f ".git-workflow/pr-context.json" ]; then
  CONTEXT_PATH=".git-workflow/pr-context.json"
elif [ -f ".claude/.pr-context.json" ]; then
  CONTEXT_PATH=".claude/.pr-context.json" # legacy read-only fallback
else
  CONTEXT_PATH=""
fi
```

**Load from the resolved `CONFIG_PATH` (if one exists):**

```yaml
qa:
  tdd:
    confirmBeforeGreen: true
    confirmBeforeRefactor: true
    maxRedAttempts: 3
    runFullSuiteEachPhase: false
    autoStartServer: false
testing:
  unit: auto
  lint: auto
  typeCheck: auto
issueTracker:
  type: auto
```

**Default Values (when no config):**

```yaml
qa:
  tdd:
    confirmBeforeGreen: true
    confirmBeforeRefactor: true
    maxRedAttempts: 3
    runFullSuiteEachPhase: false
    autoStartServer: false
```

## Step 2: Parse Arguments

Extract from `$ARGUMENTS`:

```text
$ARGUMENTS
```

**Patterns to Extract:**

| Pattern     | Example                              | Meaning              |
| ----------- | ------------------------------------ | -------------------- |
| Ticket ID   | `PROJ-123`, `ENG-456`                | Issue tracker ticket |
| GitHub Issue | `#789`                              | GitHub issue number  |
| Linear URL  | `https://linear.app/.../ENG-456/...` | Extract ticket ID    |
| Jira URL    | `https://....atlassian.net/browse/PROJ-123` | Extract ticket ID |

**Parsing Logic:**

- Extract ticket ID from URL if provided
- Linear: Pattern `/issue/([A-Z]+-\d+)/`
- Jira: Pattern `/browse/([A-Z]+-\d+)`
- GitHub: Pattern `issues/(\d+)` or `#(\d+)`

**Validation:**

- Ticket ID is required for TDD workflow
- If not provided, prompt the user for it

## Step 3: Fetch Ticket Details

### Auto-Detect Issue Tracker Type

Based on ticket format and available MCP servers:

- `^[A-Z]+-\d+$` with Linear MCP available -> Linear
- `^[A-Z]+-\d+$` with Jira config/MCP available -> Jira
- `^#?\d+$` or GitHub URL -> GitHub Issues (via `gh` CLI)

### Linear Integration

If Linear ticket format is detected, use the Linear MCP server:

```text
mcp__linear__get_issue(id: ticketId)
```

Extract:
- Title
- Description
- Acceptance criteria
- Labels (to determine bug vs feature)

### Jira Integration

If Jira is configured, use the Jira MCP server:

```text
mcp__jira__get_issue(issueKey: ticketId)
```

Extract:
- Summary (title)
- Description
- Acceptance criteria
- Issue type (Bug/Story/Task)

### GitHub Issues

If GitHub format detected:

```bash
gh issue view {issue_number} --repo {owner}/{repo} --json title,body,labels
```

### Determine Ticket Type

From ticket labels/type, determine:

| Label/Type | Classification | TDD Behavior |
| ---------- | -------------- | ------------ |
| `bug`, `Bug`, `defect` | Bug | Include reproduction step |
| `feature`, `Story`, `enhancement` | Feature | Skip reproduction |
| `refactor`, `tech-debt` | Refactor | Focus on existing tests first |

## Step 4: Explore Codebase

Gather context about the codebase:

### Find Related Files

Search for files related to the ticket:

```bash
# Search for keywords from ticket title/description
# Look for existing implementations
# Find related test files
```

**Look for:**
- Files matching keywords from ticket
- Existing test files in same area
- Related service/controller files
- Configuration files

### Analyze Test Patterns

Identify existing test patterns:

```bash
# Find test files
find . -name "*.test.ts" -o -name "*.spec.ts" -o -name "*_test.py" -o -name "*_test.go" | head -20

# Check test framework imports
grep -r "describe\|it\|test\|expect" --include="*.test.*" -l | head -5
```

**Extract:**
- Test file naming convention (`*.test.ts`, `*.spec.ts`, `*_test.py`, etc.)
- Test framework (Jest, Vitest, pytest, go test, etc.)
- Test structure (describe/it, test(), etc.)
- Mock patterns used

### Detect Test Framework

> Full per-language detection commands, tables, and the detection-results JSON shape: see `references/test-frameworks.md`.

## Step 5: Reproduce Issue (Bugs Only)

**Skip this step for features and refactors.**

For bugs, attempt to reproduce the issue:

### Optional: Start Development Server

If `qa.tdd.autoStartServer: true`:

```bash
# Detect and start dev server (background)
npm run dev &
# or
pnpm dev &
# Wait for server to be ready
sleep 5
```

### Manual Reproduction

Ask the user to confirm the bug reproduction:

**Question**: "Can you reproduce the bug? Describe the steps and current behavior."

**Options:**
1. Yes, I can reproduce it
2. No, let me try first
3. Skip reproduction (proceed to tests)

### Document Expected vs Actual

If user reproduces:

```json
{
  "reproduction": {
    "steps": ["Step 1", "Step 2"],
    "currentBehavior": "What happens now",
    "expectedBehavior": "What should happen"
  }
}
```

## Step 6: TDD RED Phase - Write Failing Tests

### Create Test File

If test file doesn't exist, create it following project conventions:

```bash
# Determine test file location
# Based on source file: src/services/auth.ts -> tests/services/auth.test.ts
# Or co-located: src/services/auth.ts -> src/services/auth.test.ts
```

### Generate Test Cases

Based on ticket acceptance criteria, generate failing tests:

> Sample generated test code for bugs and features: see `references/examples.md`.

### Run Tests - Verify RED

```bash
# Run the specific test target (varies by framework)
{TEST_COMMAND} {TEST_FILE}
```

> Per-language run commands (Go, Rust, etc.) and examples: see `references/test-frameworks.md`.

**Expected:** Tests should FAIL (RED phase)

### Handle Unexpected Results

| Result | Action |
| ------ | ------ |
| Tests fail (expected) | Proceed to GREEN phase |
| Tests pass | Warning: "Tests pass but shouldn't. Is the issue already fixed?" |
| Syntax errors | Fix test syntax, retry |
| Import errors | Fix imports, retry |

**If tests pass unexpectedly:**

**Question**: "The tests pass, but we expected them to fail. What should we do?"

**Options:**
1. Issue is already fixed - verify and close
2. Tests are incorrect - adjust test assertions
3. Different test needed - rewrite tests
4. Proceed anyway

**Max Attempts:**

Track attempts (default: `maxRedAttempts: 3`). If max reached:

**Question**: "Failed to achieve RED phase after {N} attempts. How should we proceed?"

**Options:**
1. Continue trying with guidance
2. Skip to implementation
3. Abort TDD workflow

## Step 7: TDD GREEN Phase - Implement Code

### Confirmation (If Configured)

If `qa.tdd.confirmBeforeGreen: true`:

**Question**: "RED phase complete. Tests are failing as expected. Proceed to GREEN phase?"

**Options:**
1. Yes, implement the fix/feature
2. Review tests first
3. Add more tests before implementing

### Implement Minimum Code

Write the minimum code necessary to make tests pass:

**Guidelines:**
- Focus only on passing the tests
- Don't add extra functionality
- Don't optimize yet
- Don't refactor yet

### Run Tests - Verify GREEN

```bash
# Run tests again (use the same target as RED phase)
{TEST_COMMAND} {TEST_FILE}
```

> Per-language run commands: see `references/test-frameworks.md`.

**Expected:** Tests should PASS (GREEN phase)

### Handle Failures

If tests still fail:

1. Analyze error messages
2. Fix implementation
3. Re-run tests
4. Repeat until green

Track attempts. If struggling:

**Question**: "Tests are still failing. Need help troubleshooting?"

**Options:**
1. Show me the errors - I'll help debug
2. I'll fix it manually
3. Skip to refactor phase anyway

### Optional: Run Full Suite

If `qa.tdd.runFullSuiteEachPhase: true`:

```bash
# Run full test suite
{TEST_COMMAND}
```

Ensure no regressions were introduced.

## Step 8: TDD REFACTOR Phase - Clean Up

### Confirmation (If Configured)

If `qa.tdd.confirmBeforeRefactor: true`:

**Question**: "GREEN phase complete. All tests pass. Proceed to REFACTOR phase?"

**Options:**
1. Yes, clean up the code
2. Skip refactoring - code is good enough
3. Add more tests first

### Refactoring Guidelines

Review and improve the implementation:

**Check for:**
- Code duplication
- Long methods/functions
- Poor naming
- Missing error handling
- Performance issues
- Type safety

**Do NOT:**
- Add new functionality
- Change behavior
- Break existing tests

### Run Tests After Each Change

After each refactoring change:

```bash
{TEST_COMMAND} {TEST_FILE}
```

> Per-language run commands: see `references/test-frameworks.md`.

Ensure tests remain GREEN throughout refactoring.

## Step 9: Final Verification

### Run Full Test Suite

```bash
# Run all tests
{FULL_TEST_COMMAND}

# Examples:
# npm test
# pnpm test
# pytest
# cargo test
# go test ./...
```

### Run Linting

```bash
# Auto-detected or from config
{LINT_COMMAND}

# Examples:
# npm run lint
# pnpm lint
# ruff check .
# cargo clippy
```

### Run Type Check (If Applicable)

```bash
# TypeScript
npx tsc --noEmit

# Python (mypy)
mypy .
```

### Summary of Checks

| Check | Status | Notes |
| ----- | ------ | ----- |
| New tests | PASS | {N} tests added |
| Full suite | PASS | {M} total tests |
| Linting | PASS | No issues |
| Type check | PASS | No errors |

## Step 10: Update Context

Update `.git-workflow/pr-context.json` with TDD information:

```bash
mkdir -p .git-workflow
```

Always write the canonical path. Never modify the legacy context fallback.

```json
{
  "ticket_id": "PROJ-1234",
  "ticket_url": "https://...",
  "ticket_title": "Title from ticket",
  "branch": "fix/proj-1234-description",
  "type": "fix",
  "description": "Description",
  "started_at": "2025-01-17T12:00:00Z",
  "tdd": {
    "test_files": ["tests/auth/login.test.ts"],
    "implementation_files": ["src/services/auth.ts"],
    "tests_added": 2,

    "phases_completed": ["red", "green", "refactor"],
    "completed_at": "2025-01-17T14:30:00Z"
  }
}
```

This enables `/commit` to generate better commit messages and `/finish` to include TDD summary in PR description.

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
