# Pair Programming

Collaborative AI pair programming with intelligent role management, real-time quality monitoring, and comprehensive development workflows.

## What This Skill Does

This skill provides professional pair programming capabilities with AI assistance, supporting multiple collaboration modes, continuous verification, and integrated testing. It manages driver/navigator roles, performs real-time code review, tracks quality metrics, and ensures high standards through truth-score verification.

**Key Capabilities:**
- **Multiple Modes**: Driver, Navigator, Switch, TDD, Review, Mentor, Debug
- **Real-Time Verification**: Automatic quality scoring with rollback on failures
- **Role Management**: Seamless switching between driver/navigator roles
- **Testing Integration**: Auto-generate tests, track coverage, continuous testing
- **Code Review**: Security scanning, performance analysis, best practice enforcement
- **Session Persistence**: Auto-save, recovery, export, and sharing

## Prerequisites

**Required:**
- Claude Flow CLI installed (`npm install -g claude-flow@alpha`)
- Git repository (optional but recommended)

**Recommended:**
- Testing framework (Jest, pytest, etc.)
- Linter configured (ESLint, pylint, etc.)
- Code formatter (Prettier, Black, etc.)

## Quick Start

### Basic Session
```bash
# Start simple pair programming
claude-flow pair --start
```

### TDD Session
```bash
# Test-driven development
claude-flow pair --start \
  --mode tdd \
  --test-first \
  --coverage 90
```

```bash
# Basic start
claude-flow pair --start

# Expert refactoring session
claude-flow pair --start \
  --agent senior-dev \
  --focus refactor \
  --verify \
  --threshold 0.98

/pause [--reason <reason>]

# Resume session
/resume

# End session
claude-flow pair --end [--save] [--report]
```

### Available Modes

#### Driver Mode
You write code while AI provides guidance.

```bash
claude-flow pair --start --mode driver
```

**Your Responsibilities:**
- Write actual code
- Implement solutions
- Make immediate decisions
- Handle syntax and structure

**AI Navigator:**
- Strategic guidance
- Spot potential issues
- Suggest improvements
- Real-time review
- Track overall direction

**Best For:**
- Learning new patterns
- Implementing familiar features
- Quick iterations
- Hands-on debugging

**Commands:**
```
/suggest     - Get implementation suggestions
/review      - Request code review
/explain     - Ask for explanations
/optimize    - Request optimization ideas
/patterns    - Get pattern recommendations
```

#### Navigator Mode
AI writes code while you provide direction.

```bash
claude-flow pair --start --mode navigator
```

**Your Responsibilities:**
- Provide high-level direction
- Review generated code
- Make architectural decisions
- Ensure business requirements

**AI Driver:**
- Write implementation code
- Handle syntax details
- Implement your guidance
- Manage boilerplate
- Execute refactoring

**Best For:**
- Rapid prototyping
- Boilerplate generation
- Learning from AI patterns
- Exploring solutions

**Commands:**
```
/implement   - Direct implementation
/refactor    - Request refactoring
/test        - Generate tests
/document    - Add documentation
/alternate   - See alternative approaches
```

#### Switch Mode
Automatically alternates roles at intervals.

```bash
# Default 10-minute intervals
claude-flow pair --start --mode switch

# 5-minute intervals (rapid)
claude-flow pair --start --mode switch --interval 5m

# 15-minute intervals (deep focus)
claude-flow pair --start --mode switch --interval 15m
```

**Handoff Process:**
1. 30-second warning before switch
2. Current driver completes thought
3. Context summary generated
4. Roles swap smoothly
5. New driver continues

**Best For:**
- Balanced collaboration
- Knowledge sharing
- Complex features
- Extended sessions

/implement JWT token generation with refresh tokens
> AI generates secure token implementation

/test-gen
> AI creates comprehensive test suite

[SWITCH TO DRIVER]

[DRIVER: You - 10 minutes]
# You refine the implementation
/review --security
> AI performs security review, suggests improvements

/commit --message "feat: JWT authentication with refresh tokens"
✅ Truth Score: 0.98 - Committed successfully
```

#### Example 2: Bug Fixing

Debugging a memory leak in Node.js:

```bash
# Session setup
claude-flow pair --start \
  --mode navigator \
  --agent debugger-expert \
  --focus debug \
  --trace
```

**Session Flow:**
```
👥 Starting debugging session...

/status
> Analyzing application for memory issues...

/perf --profile
> Memory usage growing: 150MB → 450MB over 10 minutes

/find "new EventEmitter" --regex
> Found 3 instances of EventEmitter creation

/inspect eventEmitters --deep
> Discovering listeners not being removed

/suggest fix for memory leak

> Memory stable at 150MB ✅

/commit --message "fix: memory leak in event emitters"
```

#### Example 3: TDD Session

Building shopping cart with test-driven development:

```bash
# Session setup
claude-flow pair --start \
  --mode tdd \
  --agent tdd-specialist \
  --test-first
```

**Session Flow:**
```
👥 TDD Session: Shopping Cart Feature

[RED PHASE]
/test-gen "add item to cart"
> AI writes failing test:
  ✗ should add item to cart
  ✗ should update quantity for existing item
  ✗ should calculate total price

[GREEN PHASE]
/implement minimal cart functionality
> You write just enough code to pass tests

/test
> Tests passing: 3/3 ✅

[REFACTOR PHASE]
/refactor --pattern repository
> AI refactors to repository pattern

/test
> Tests still passing: 3/3 ✅

[NEXT CYCLE]
/test-gen "remove item from cart"
> AI writes new failing tests...
```

#### Example 4: Code Refactoring

Modernizing legacy code:

```bash
# Session setup
claude-flow pair --start \
  --mode driver \
  --focus refactor \
  --verify \
  --threshold 0.98
```

**Session Flow:**
```
👥 Refactoring Session: Modernizing UserService

/analyze UserService.js
> AI identifies:
  - Callback hell (5 levels deep)
  - No error handling
  - Tight coupling
  - No tests

/suggest refactoring plan
> AI suggests:
  1. Convert callbacks to async/await
  2. Add error boundaries
  3. Extract dependencies
  4. Add unit tests

/test-gen --before-refactor
> AI generates tests for current behavior

/refactor callbacks to async/await
# You refactor with AI guidance

/test
> All tests passing ✅

/review --compare
> AI shows before/after comparison

  GET    /api/posts
  GET    /api/posts/:id
  PUT    /api/posts/:id
  DELETE /api/posts/:id

/implement CRUD endpoints with validation

### Best Practices

#### Session Practices
1. **Clear Goals** - Define session objectives upfront
2. **Appropriate Mode** - Choose based on task type
3. **Enable Verification** - For critical code paths
4. **Regular Testing** - Maintain quality continuously
5. **Session Notes** - Document important decisions
6. **Regular Breaks** - Take breaks every 45-60 minutes

#### Code Practices
1. **Test Early** - Run tests after each change
2. **Verify Before Commit** - Check truth scores
3. **Review Security** - Always for sensitive code
4. **Profile Performance** - Use `/perf` for optimization
5. **Save Sessions** - For complex work
6. **Learn from AI** - Ask questions frequently

#### Mode Selection
- **Driver Mode**: When learning, controlling implementation
- **Navigator Mode**: For rapid prototyping, generation
- **Switch Mode**: Long sessions, balanced collaboration
- **TDD Mode**: Building with tests
- **Review Mode**: Quality focus
- **Mentor Mode**: Learning priority
- **Debug Mode**: Fixing issues

### Troubleshooting

#### Session Won't Start
- Check agent availability
- Verify configuration file syntax
- Ensure clean workspace
- Review log files

#### Session Disconnected
- Use `--recover` to restore
- Check network connection
- Verify background processes
- Review auto-save files

#### Poor Performance
- Reduce verification threshold
- Disable continuous testing
- Check system resources
- Use lighter AI model

#### Configuration Issues
- Validate JSON syntax
- Check file permissions
- Review priority order (CLI > env > project > user > global)
- Run `claude-flow pair config validate`
