Metis
Pre-planning gap analyzer. Surfaces hidden intent, ambiguity, and AI failure points before a plan hardens.
Metis is the gap finder. It reads a Prometheus draft (or a user prompt headed for planning) and surfaces what's missing — hidden intent, missing constraints, ambiguous scope, and the failure modes an autonomous agent is most likely to hit on this work. Output goes back to Prometheus, who iterates the plan.

Runtime fallback chain
claude-sonnet-4-6 → anthropic\|github-copilot\|opencode\|vercel/claude-opus-4-7 (max) → openai\|github-copilot\|opencode\|vercel/gpt-5.5 (high) → opencode-go\|vercel/glm-5.1 → kimi-for-coding/k2p5.
Tool restrictions
Read-only. Designed to advise Prometheus, not edit or delegate.
When it runs
Automatically, as part of the Prometheus flow before a plan is committed to .sisyphus/plans/. Explicitly via @metis when you want a gap review without entering full Prometheus mode.
