Claude-Codex-Gemini tri-model orchestration via /ask codex + /ask antigravity (or gemini), then Claude synthesizes results

CCG - Claude-Codex-Gemini Tri-Model Orchestration

CCG routes through the canonical /ask skill (/ask codex + /ask antigravity), then Claude synthesizes both outputs into one answer.

Use this when you want parallel external perspectives without launching tmux team workers.

When to Use

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

Requirements

  • Codex CLI: npm install -g @openai/codex (or @openai/codex)
  • Antigravity CLI (Google's successor to the Gemini CLI): install the agy binary per the official Antigravity instructions (inspect any installer before running it). Verify: agy --version
  • Gemini CLI remains supported for enterprise/API-key use cases: 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)
   - Antigravity prompt (UX/design/docs/alternatives) — use gemini for enterprise

2. Claude runs via CLI (skill nesting not supported):
   - `omc ask codex "<codex prompt>"`
   - `omc ask antigravity "<antigravity prompt>"`
     (or `omc ask gemini "<gemini prompt>"` for enterprise)

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

4. Claude synthesizes both outputs into one final response

Execution Protocol

When invoked, Claude MUST follow this workflow:

1. Decompose Request

Split the user request into:

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

2. Invoke advisors via CLI

Note: Skill nesting (invoking a skill from within an active skill) is not supported in Claude Code. Always use the direct CLI path via Bash tool.

Run both advisors (use antigravity or gemini depending on your setup):

omc ask codex "<codex prompt>"
omc ask antigravity "<antigravity prompt>"

Enterprise fallback:

omc ask gemini "<gemini prompt>"

3. Collect artifacts

Read latest ask artifacts from:

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

4. Synthesize

Return one unified answer with:

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

Fallbacks

If one provider is unavailable:

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

If both unavailable:

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

Invocation
