CCG - Claude-Codex-Gemini Tri-Model Orchestration

Route a task through three AI models in parallel, then synthesize their outputs into one unified answer.

When to Use

Backend/analysis + frontend/UI work in one request
Code review from multiple perspectives
Cross-validation where models may disagree
Fast parallel input without full team orchestration

When NOT to Use

Simple, straightforward tasks → execute directly
Already clear on approach → use /omg-autopilot
Need coordinated multi-agent work → use /team

Requirements

Codex CLI: npm install -g @openai/codex
Gemini CLI: npm install -g @google/gemini-cli
If either CLI is unavailable, continue with whichever provider works

Execution Protocol

1. Decompose Request

Split the user request into:

Codex prompt: architecture, correctness, backend, risks, test strategy
Gemini prompt: UX/content clarity, alternatives, edge-case usability, docs polish
Synthesis plan: how to reconcile conflicts

2. Invoke Advisors

Run both advisors via CLI in parallel:

# Run in terminal
codex "<codex prompt>"
gemini "<gemini prompt>"

Or via VS Code's selectChatModels() API if available:

Promise.all([
  model_openai.sendRequest(codex_prompt),
  model_google.sendRequest(gemini_prompt)
])

3. Collect Results

Gather outputs from both advisors.

4. Synthesize

Return one unified answer with:

Agreed recommendations
Conflicting recommendations (explicitly called out)
Chosen final direction + rationale
Action checklist

Fallbacks

Scenario	Action
One provider unavailable	Continue with available + Claude synthesis
Both unavailable	Fall back to Claude-only answer

Example

/ccg Review this PR - architecture/security via Codex and UX/readability via Gemini

Output:

=== CCG Synthesis ===

## Agreed
- Authentication middleware needs rate limiting
- Error messages should be more user-friendly

## Conflicting
- Codex: Use middleware pattern for validation
- Gemini: Use inline validation for simplicity
→ Chosen: Middleware pattern (consistency with existing codebase)

## Action Checklist
- [ ] Add rate limiting middleware
- [ ] Improve error messages in auth flow
- [ ] Extract validation to middleware layer

Install ccg and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.
