CCG - Claude + Codex + Gemini Multi-Model Collaboration

简体中文 | English

A multi-model collaboration development system where Claude Code orchestrates Codex + Gemini. Frontend tasks route to Gemini, backend tasks route to Codex, and Claude handles orchestration and code review.

Why CCG?

• Zero-config model routing — Frontend tasks automatically go to Gemini, backend tasks to Codex. No manual switching.
• Security by design — External models have no write access. They return patches; Claude reviews before applying.
• 27 slash commands — From planning to execution, git workflow to code review, all accessible via /ccg:*.
• Spec-driven development — Integrates OPSX to turn vague requirements into verifiable constraints, eliminating AI improvisation.

External models have no write access — they only return patches, which Claude reviews before applying.
