Consult external AIs (Gemini 2.5 Pro, OpenAI Codex, Claude) for second opinions. Use for debugging failures, architectural decisions, security validation, or need fresh perspective with synthesis.
SKILL.md
Multi-AI Consultant
Consult external AIs for second opinions when Claude Code is stuck or making critical decisions.
What This Skill Does
This skill enables future Claude Code sessions to consult other AIs when:
Stuck on a bug after one failed attempt
Making architectural decisions
Security concerns need validation
Fresh perspective needed
Key innovation: Uses existing CLI tools (gemini, codex) instead of building MCP servers - much simpler and more maintainable.
When to Use This Skill
Automatic Triggers (No User Action Needed)
Claude Code should automatically suggest using this skill when:
After 1 failed debugging attempt
Tried one approach to fix a bug
Still not working or different error
→ Suggest: "Should I consult [Gemini|Fresh Claude] for a second opinion?"
Before architectural decisions
Significant design choices (state management, routing, data flow)
Framework selection
Database schema design
→ Auto-consult (mention to user): "Consulting Gemini for architectural validation..."
Security changes
Authentication logic
Authorization rules
Cryptography
Input validation
→ Auto-consult: "Consulting Gemini to verify security approach..."
When uncertain
Multiple valid approaches
Trade-offs not clear
Conflicting advice in documentation
→ Suggest: "Would you like me to consult another AI for additional perspective?"
Manual Invocation (User Commands)
User can explicitly request consultation with:
/consult-gemini [question] - Gemini 2.5 Pro with thinking, search, grounding
/consult-codex [question] - OpenAI GPT-4 via Codex CLI (repo-aware)
/consult-claude [question] - Fresh Claude subagent (free, fast)
/consult-ai [question] - Router that asks which AI to use

The 5-Part Synthesis Format
Every consultation must follow this format (prevents parroting):
🤖 My Analysis - Claude's original reasoning and attempts
💎/🔷/🔄 Other AI's Analysis - External AI's complete response
🔍 Key Differences - Agreement, divergence, what each AI caught/missed
