Use for /c-level-agents:cross-eval, or when a high-stakes memo needs independent review by several models before the boardroom.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /c-level-agents:cross-eval — Multi-Model Consensus **Command:** `/c-level-agents:cross-eval <memo-or-brief>` Runs the same memo through multiple model providers and reconciles divergences. Use for **high-stakes, irreversible decisions** where single-model bias is too costly: M&A, major fundraises, layoffs, strategic pivots, regulatory commitments. Adapted from gstack's `/codex` cross-review pattern, generalized to **business memos** instead of code PRs. ## When to Run - Before signing a term sheet - Before announcing a layoff - Before committing to a regulated market - Before any decision where reversing costs > 6 months of company time - When the boardroom vote was split or had a CRITICAL dissent ## Models Used (graceful degradation) The command tries to invoke each available model in order: 1. **Claude** (primary, always available) — the boardroom's native voice 2. **Codex / OpenAI** (if `OPENAI_API_KEY` or `codex` CLI available) 3. **Gemini** (if `GEMINI_API_KEY` or `gemini` CLI available) If only Claude is available, the command runs **Claude-only with adversarial mode** — same model, different prompt seeds — and clearly labels the output as single-model. …

How to install
mdr add alirezarezvani/claude-skills/cross-eval@sha256:40dcb9ab9eb8d9ccThe line at the top of this page pins the label git:20261030.91a20ba, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
