Use when reviewing an implementation plan document (docs/superpowers/plans/*.md or similar) for LLM-style overengineering before implementation. Runs a rubric-driven Claude pass plus a Codex adversarial pass, merges findings, and proposes specific edits to slim the plan. Triggers on 'check this plan for bloat', 'is this overengineered', 'detect overengineering', or invoked as /detect-overengineering.
