Diagnose and fix problems on any machine using a persistent, per-machine forensics knowledge base that the agent builds and maintains itself. Agent-agnostic - works for any coding agent, any OS. Use when the user reports something broken, failing, slow, missing, or asks to "check" a machine, an app, or an agent itself, before exploring from scratch. Reads this machine's existing knowledge base first, learns from recorded past mistakes, then attributes, reproduces, fixes, and writes findings back.
