Codebase Question Answering

Retrieval and reasoning over a codebase, answering orientation questions that would otherwise require reading widely or interrupting someone.

Large codebases, onboarding, and cross-team work where nobody holds the whole picture.

Questions requiring certainty about all call sites. Retrieval-based answers are not exhaustive, and 'nothing else uses this' is a claim it cannot support.

Answers asserting completeness should be verified with static analysis rather than trusted, particularly before a deletion.

Confident incompleteness — describing three of five implementations of a pattern, with nothing indicating two were missed.

Asking which code paths write to the reconciliation status field before changing its state machine, then verifying the answer with static analysis.
