CCG - Claude-Codex-Gemini Tri-Model Orchestration

CCG routes through the canonical /ask skill (/ask codex + /ask gemini), 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 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 via CLI (skill nesting not supported):
   - `omc ask codex "<codex prompt>"`
   - `omc ask gemini "<gemini prompt>"`

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

Gemini 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:

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

3. Collect artifacts

Read latest ask artifacts from:

.omc/artifacts/ask/codex-*.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
