CCG - Claude-Codex-Gemini Tri-Model Orchestration

ask-codex

ask-gemini

When to Use

• Backend/analysis + frontend/UI work in one request
• Code review from multiple perspectives (architecture + design/UX)
• Cross-validation where Codex and Gemini may disagree
• Fast advisor-style parallel input without team runtime orchestration

Requirements

• Codex CLI:

  npm install -g @openai/codex

  (or

  @openai/codex

  )
• Gemini CLI:

  npm install -g @google/gemini-cli

• omc ask

  command available
• If either CLI is unavailable, continue with whichever provider is available and note the limitation

How It Works

1. Claude decomposes the request into two advisor prompts:
   - Codex prompt (analysis/architecture/backend)
   - Gemini prompt (UX/design/docs/alternatives)

2. Claude runs:
   - /oh-my-claudecode:ask-codex "<codex prompt>"
   - /oh-my-claudecode:ask-gemini "<gemini prompt>"

   (equivalent CLI path: `omc ask codex ...` + `omc ask gemini ...`)

3. Artifacts are written under `.omc/artifacts/ask/`

4. Claude synthesizes both outputs into one final response

Execution Protocol

1. Decompose Request

• 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 ask skills

/oh-my-claudecode:ask-codex <codex prompt>
/oh-my-claudecode:ask-gemini <gemini prompt>

omc ask codex "<codex prompt>"
omc ask gemini "<gemini prompt>"

3. Collect artifacts

.omc/artifacts/ask/codex-*.md
.omc/artifacts/ask/gemini-*.md

4. Synthesize

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

Fallbacks

• Continue with available provider + Claude synthesis
• Clearly note missing perspective and risk

• Fall back to Claude-only answer and state CCG external advisors were unavailable
