Read-only root-cause analysis for any bug, test failure, or unexpected behavior — before proposing or writing any fix. Produces a brief with the root cause, files to change, approach, and risks. No edits, no commits, no state-changing commands. Use before /fix or /conductor whenever the cause isn't already proven. If static reading can't reach a confident cause, it hands off to /debugging-difficult-bugs for runtime instrumentation.
