Multi-Model Consensus
Runs a high-stakes board memo or strategy brief through multiple AI models (Claude, Codex, Gemini) to get independent reviews and reconcile divergences. It produces a structured cross-eval report with vote tallies, consensus and divergent concerns, and a recommendation, acting as a safety net before irreversible decisions.
✨ What it does
- Invokes multiple model providers (Claude, Codex, Gemini) with graceful degradation if some are unavailable.
- Sends each model an independent reviewer prompt that demands top concerns, supports, and a vote (APPROVE/REJECT/DEFER).
- Reconciles reviews to identify consensus concerns (flagged by ≥2 models) and divergent concerns (flagged by 1 model).
- Generates a vote tally table and a recommendation (GO/PAUSE/STOP) based on model votes and critical concerns.
- Lists open questions for the founder arising from divergences.
- Falls back to adversarial single-model mode (three Claude passes) when only Claude is available, clearly labeling the ou
🎯 When to use it
- Before signing a term sheet or committing to a major fundraise.
- Before announcing layoffs or a strategic pivot.
- Before entering a regulated market or making a regulatory commitment.
- When the boardroom vote was split or had a critical dissent.
- For any decision where the cost of reversing exceeds six months of company time.
🚀 How to use
Trigger: /cs:cross-eval
Trigger with the slash command /cs:cross-eval followed by the memo or brief text (or a reference to it). The skill reads the memo, probes for available model CLIs/API keys, and runs the review. Example prompts:
/cs:cross-eval <paste memo here>
/cs:cross-eval @path/to/memo.md
📄 Output: A markdown report saved to ~/.claude/cross-eval/YYYY-MM-DD-<slug>.md containing vote tally, consensus/divergent concerns, recommendation, and open questions.

⚠️ Good to know
Requires API keys or CLIs for Codex and Gemini to achieve true multi-model consensus; otherwise it falls back to a weaker single-model adversarial mode. It is not a replacement for outside counsel or a real board.
❓ FAQ
What happens if only Claude is available?
The command runs in adversarial mode with three independent Claude passes (standard, devil's advocate, steelman) and labels the output as single-model, treating it as suggestive rather than conclusive.
How is the recommendation determined?
It is GO if 2+ models approve and no critical concerns from any model; PAUSE if any model defers or any concern is critical; STOP if 2+ models reject.
What does the output file contain?
It includes the date, memo link, models invoked, a vote tally table, consensus and divergent concerns, consensus supports, a recommendation, and open questions for the founder.
