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
- Format the prompt — make it model-agnostic (no Claude-specific syntax)
- Spawn in parallel:
- Claude (current session, native)
- Codex (via OpenAI API, if configured)
- Gemini (via Google API, if configured)
- Collect responses
- Synthesize:
- Where do they agree? → high confidence
- Where do they disagree? → flag for human review
- Combine the strongest reasoning from each
- 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."
