diagnose
Diagnose why a Claude Code plugin skill fails to load, doesn't trigger when expected, errors out, or behaves unexpectedly. Use proactively whenever you notice a plugin or skill misbehaving, or when the user reports something like: "why isn't this working", "plugin not triggering", "skill broken", "debug plugin", "diagnose plugin", "this skill should have fired", "fix plugin", "skill overlap", "wrong skill triggered". Also trigger when a hook fails silently, a plugin won't load, or tools from an MCP server aren't available. Does NOT cover: overall plugin health audits (use reflect), size optimization (use optimize), or version releases (use release).
