name	ai-pair-programming
description	Orchestrates a dual-AI engineering loop where a Primary AI plans and implements, while a Review AI validates and reviews, with continuous feedback for optimal code quality. Supports custom AI pairing (Claude, Codex, Gemini, etc.)

AI Pair Programming Skill

Overview

A flexible pair programming workflow that allows you to combine any two AI assistants for collaborative development. Configure your preferred AI pair based on their strengths.

AI Configuration

Before using this skill, configure your AI pair by setting the following roles:

Role	Description	Examples
Primary AI	Handles architecture, planning, and code implementation	Claude, Gemini, GPT-4
Review AI	Validates plans and reviews code for quality assurance	Codex, Claude, Gemini

Example Configurations

Configuration	Primary AI	Review AI	Use Case
Claude + Codex	Claude	Codex	Strong planning + Fast validation
Claude + Gemini	Claude	Gemini	Multi-model perspective
Gemini + Claude	Gemini	Claude	Leverage Gemini's context + Claude's review
GPT-4 + Codex	GPT-4	Codex	GPT planning + Codex validation

Setting Up Your AI Pair

Replace {{PRIMARY_AI}} and {{REVIEW_AI}} placeholders throughout this skill with your chosen AI names.

Example:

• {{PRIMARY_AI}} → Claude
• {{REVIEW_AI}} → Codex

For command-line tools, replace {{REVIEW_AI_CLI}} with the appropriate CLI command:

• Codex: codex exec --sandbox read-only
• Claude: claude --print
• Gemini: gemini
• Other: Use your AI's CLI tool

Note: CLI commands are examples. Please verify the correct CLI syntax for your specific AI tools and their current versions.

Core Workflow Philosophy

This skill implements a balanced engineering loop:

• {{PRIMARY_AI}}: Architecture, planning, and execution
• {{REVIEW_AI}}: Validation and code review
• Continuous Review: Each AI reviews the other's work
• Context Handoff: Always continue with whoever last cleaned up

Note: Model + reasoning settings are assumed to be handled by each AI's existing config. Commands below use generic placeholders.

Phase 1: Planning with {{PRIMARY_AI}}

1. Start by creating a detailed plan for the task
2. Break down the implementation into clear steps
3. Document assumptions and potential issues
4. Output the plan in a structured format

Phase 2: Plan Validation with {{REVIEW_AI}}

1. Send the plan to {{REVIEW_AI}} for validation:

echo "Review this implementation plan and identify any issues:
[{{PRIMARY_AI}}'s plan here]

Check for:
- Logic errors
- Missing edge cases
- Architecture flaws
- Security concerns" | {{REVIEW_AI_CLI}}

2. Capture {{REVIEW_AI}}'s feedback

Phase 3: Feedback Loop

If {{REVIEW_AI}} finds issues:

1. Summarize {{REVIEW_AI}}'s concerns to the user
2. Refine the plan based on feedback
3. Ask user (via AskUserQuestion): "Should I revise the plan and re-validate, or proceed with fixes?"
4. Repeat Phase 2 if needed

Phase 4: Execution

Once the plan is validated:

1. {{PRIMARY_AI}} implements the code using available tools (Edit, Write, Read, etc.)
2. Break down implementation into manageable steps
3. Execute each step carefully with proper error handling
4. Document what was implemented

Phase 5: Cross-Review After Changes

After every change:

1. Send {{PRIMARY_AI}}'s implementation to {{REVIEW_AI}} for review:
   • Bug detection
   • Performance issues
   • Best practices validation
   • Security vulnerabilities
2. {{PRIMARY_AI}} analyzes {{REVIEW_AI}}'s feedback and decides:
   • Apply fixes immediately if issues are critical
   • Discuss with user if architectural changes needed
   • Document decisions made

Phase 6: Iterative Improvement

1. After {{REVIEW_AI}} review, {{PRIMARY_AI}} applies necessary fixes
2. For significant changes, send back to {{REVIEW_AI}} for re-validation
3. Continue the loop until code quality standards are met
4. For AI tools that support session continuation, use the resume flag:

echo "Review the updated implementation" | {{REVIEW_AI_CLI}} --resume

Note: Session resumption support varies by AI tool. For tools without resume support, start a new session with full context.

Recovery When Issues Are Found

When {{REVIEW_AI}} identifies problems:

1. {{PRIMARY_AI}} analyzes the root cause
2. Implements fixes using available tools
3. Sends updated code back to {{REVIEW_AI}} for verification
4. Repeats until validation passes

When implementation errors occur:

1. {{PRIMARY_AI}} reviews the error/issue
2. Adjusts implementation strategy
3. Re-validates with {{REVIEW_AI}} before proceeding

Best Practices

• Always validate plans before execution
• Never skip cross-review after changes
• Maintain clear handoff between AIs
• Document who did what for context
• Use resume to preserve session state (check your AI tool's documentation for support)

Command Reference

Phase	Command Pattern	Purpose
Validate plan	echo "plan" | {{REVIEW_AI_CLI}}	Check logic before coding
Implement	{{PRIMARY_AI}} uses Edit/Write/Read tools	{{PRIMARY_AI}} implements the validated plan
Review code	echo "review changes" | {{REVIEW_AI_CLI}}	{{REVIEW_AI}} validates {{PRIMARY_AI}}'s implementation
Continue review	echo "next step" | {{REVIEW_AI_CLI}} --resume	Continue validation session (if supported)
Apply fixes	{{PRIMARY_AI}} uses Edit/Write tools	{{PRIMARY_AI}} fixes issues found by {{REVIEW_AI}}
Re-validate	echo "verify fixes" | {{REVIEW_AI_CLI}}	{{REVIEW_AI}} re-checks after fixes

Note: The --resume flag is supported by some AI tools (e.g., Codex). For tools without resume support, start a new session with the necessary context.

Error Handling

1. Stop on non-zero exit codes from {{REVIEW_AI}}
2. Summarize {{REVIEW_AI}} feedback and ask for direction via AskUserQuestion
3. Before implementing changes, confirm approach with user if:
   • Significant architectural changes needed
   • Multiple files will be affected
   • Breaking changes are required
4. When {{REVIEW_AI}} warnings appear, {{PRIMARY_AI}} evaluates severity and decides next steps

The Perfect Loop

Plan ({{PRIMARY_AI}}) → Validate Plan ({{REVIEW_AI}}) → Feedback →
Implement ({{PRIMARY_AI}}) → Review Code ({{REVIEW_AI}}) →
Fix Issues ({{PRIMARY_AI}}) → Re-validate ({{REVIEW_AI}}) → Repeat until perfect

This creates a self-correcting, high-quality engineering system where:

• {{PRIMARY_AI}} handles all code implementation and modifications
• {{REVIEW_AI}} provides validation, review, and quality assurance
