Systematic root-cause debugging — reproduce, isolate, fix at the source, prove the fix. Use when the user reports a bug, an error, a crash, flaky behavior, "this doesn't work", "why is this failing", or pastes a stack trace or failing test output.
Set up and maintain a lightweight, file-based knowledge graph of the repo — entities, typed relations, decisions, gotchas — so agents load context fast instead of re-exploring the codebase every session. Use when the user says "knowledge graph", "remember…
