name: dev-ccg description: Tri-model orchestration — run the same task through Claude + Codex + Gemini in parallel and synthesize the best answer. Use for high-stakes decisions where multi-model consensus reduces single-model bias.

Dev CCG (Claude + Codex + Gemini)

Derived from oh-my-claudecode (MIT, Yeachan Heo). Adapted for the EvoNexus Engineering Layer.

EXPERIMENTAL. Tri-model orchestration: run the same prompt through Claude, Codex (OpenAI Codex / GPT-Code), and Gemini in parallel, then synthesize the best answer.

Note: This skill assumes external API access to Codex and Gemini, which may or may not be configured in EvoNexus. If only Claude is available, the skill degrades to single-model mode and warns the user.

Use When

• High-stakes decision where single-model bias is a real concern
• Architectural choice where you want multiple LLMs' perspectives
• Code review where you want adversarial multi-model agreement

Do Not Use When

• Routine work — single model is fine
• API access to Codex/Gemini is not configured
• The task requires real-time iteration (CCG is slow)

Workflow

1. Format the prompt — make it model-agnostic (no Claude-specific syntax)
2. Spawn in parallel:
   • Claude (current session, native)
   • Codex (via OpenAI API, if configured)
   • Gemini (via Google API, if configured)
3. Collect responses
4. Synthesize:
   • Where do they agree? → high confidence
   • Where do they disagree? → flag for human review
   • Combine the strongest reasoning from each
5. Save to workspace/development/research/[C]ccg-{topic}-{date}.md

Output

## CCG Synthesis — {topic}

### Models Consulted
- ✅ Claude (Opus 4.6)
- ✅ Codex (gpt-code-X)
- ✅ Gemini (gemini-Y)

### Agreement Zones
- All three agree on: {points}

### Disagreement Zones
- Claude says X
- Codex says Y
- Gemini says Z
- → Flagged for human review

### Synthesized Answer
[Combined reasoning, marking uncertainty zones]

Pairs With

• @apex-architect (for high-stakes architectural decisions)
• @raven-critic (for adversarial cross-validation)

Configuration

If Codex/Gemini APIs are not configured, this skill warns:

"CCG requires Codex and Gemini API access. Currently only Claude is available — falling back to single-model mode. Configure via dev-mcp-setup if needed."
