# Multi-Model Dispatch This skill teaches Claude Code how to correctly invoke Codex and Gemini CLIs for independent review of artifacts. Use this whenever a pipeline step needs multi-model validation at depth 4-5. ## When This Skill Activates - A review or validation step is running at depth 4+ and wants independent model validation - User asks to "run multi-model review" or "get a second opinion from Codex/Gemini" - The `automated-pr-review` step is using local CLI review mode - The `implementation-plan-review` step dispatches to external CLIs at depth 4+ ## CLI Detection & Auth Verification Before attempting any dispatch, detect what's available AND verify authentication. A CLI that's installed but not authenticated is useless in headless mode — it will hang on an interactive auth prompt or fail silently. ### Step 1: Check CLI Installation ```bash command -v codex && echo "codex installed" || echo "codex not found" command -v gemini && echo "gemini installed" || echo "gemini not found" ``` ### Step 2: Verify Authentication **CRITICAL: Do not skip this step.** Auth tokens expire mid-session. A CLI that worked 30 minutes ago may fail now. **CRITICAL: Previous auth failures do NOT exempt subsequent dispatches.** Auth tokens refresh — a CLI that failed auth during user story review may work fine for domain modeling review. Always re-check auth before EACH review step, not once per session. **Codex auth check** (has a built-in status command): ```bash codex login stat
