# Diagnosing Superpowers (agent skill)

> Diagnosing Superpowers is an agent skill (a SKILL.md file) from obra/superpowers. Agents load it when a superpowers session went wrong and your human partner wants to know why — repeated work, ignored plans… It works with Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot and OpenCode and has 296,071 GitHub stars across a repository of 10 listed skills.

Use when a superpowers session went wrong and your human partner wants to know why — repeated work, ignored plans, stumbles, poor results, a skill that didn't fire, "it took too long", "why is it so expensive", "what is it doing" — or wants to build a bug report for the superpowers maintainers, for the current session or a past one identified by id or path, on any harness.
