CCG

Overview

CCG (Claude-Codex-Gemini) is a tri-model orchestration that simultaneously queries Codex and Gemini, then has Claude synthesize both responses into a single unified answer.

It uses the /ask skill to collect external perspectives lightly, without spinning up tmux team workers.

Usage

/oh-my-claudecode:ccg "Review this PR - architecture/security via Codex and UX/readability via Gemini"

Also activated via magic keywords.

ccg review the authentication flow
claude-codex-gemini analyze this API design

How It Works

1. Request decomposition: Claude breaks the request into two advisor prompts
   • Codex prompt: architecture, correctness, backend, risks, test strategy
   • Gemini prompt: UX/content clarity, alternatives, edge cases, documentation
2. Parallel queries: Runs /ask codex and /ask gemini simultaneously
3. Artifact collection: Reads results from .omc/artifacts/ask/
4. Synthesis: Claude combines both outputs into a single unified answer

Synthesis Output Format

• Agreed recommendations
• Conflicting recommendations (explicitly marked)
• Selected final direction + rationale
• Action checklist

When to Use

• When a single request spans backend/analysis and frontend/UI work
• Code reviews that need both architecture and design/UX perspectives
• Cross-validation where Codex and Gemini may offer differing opinions
• When quick advisor input is needed without team runtime orchestration

Fallback

• If one provider is unavailable, proceeds with the available provider + Claude synthesis
• If both providers are unavailable, falls back to Claude-only answer

Requirements

• Codex CLI: npm install -g @openai/codex
• Gemini CLI: npm install -g @google/gemini-cli
