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

How Claude Code Uses This

The CLI holds the session state; Claude Code reads it. There is no REPL to type into.

1. At the start of every turn run ruflo pair status --json. If active is false, this skill is dormant.
2. Follow mode and aiRole. As driver you write the code and the human reviews. As navigator you review and suggest and never edit unless asked. tdd, review, mentor and debug refine that behaviour as described below.
3. When switchDue is true, run ruflo pair switch, announce the swap, and continue in the new role.
4. Change mode mid-session with ruflo pair mode <mode>. The human can run the same commands from their shell.

State lives in .claude-flow/sessions/pair/current.json. ruflo pair end archives it to history.jsonl next to it.

Prerequisites

Required:

• Ruflo CLI installed (npm install -g ruflo), which provides the ruflo pair command
• Git repository (optional but recommended)

Recommended:

• Testing framework (Jest, pytest, etc.)
• Linter configured (ESLint, pylint, etc.)
• Code formatter (Prettier, Black, etc.)

$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:

# Session setup
ruflo pair start \
  --mode navigator \
  --agent debugger-expert \
  --focus debug \
  --trace

Session Flow:

👥 Starting debugging session...

> AI identifies:
  - Callback hell (5 levels deep)
  - No error handling
  - Tight coupling
  - No tests

$suggest refactoring plan

  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 ✅

$perf --profile
> React DevTools Profiler Results:
  - ProductList: 450ms render
  - CartSummary: 200ms render
  - Unnecessary re-renders: 15

$suggest optimizations for ProductList
> AI suggests:
  1. Add React.memo
  2. Use useMemo for expensive calculations
  3. Implement virtualization for long lists

$implement React.memo and useMemo
# You implement with AI guidance

$perf --profile
> ProductList: 45ms render (90% improvement!) ✅

$implement virtualization with react-window

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

$implement CRUD endpoints with validation
> AI implements with Express + Joi validation

$test-gen --integration
> AI generates integration tests

$security --api
> AI adds:
  - Rate limiting
  - Input sanitization
  - JWT authentication
  - CORS configuration

$document --openapi
