Conducts deep-dive analysis of existing codebases to verify architectural assumptions and establish factual patterns for implementation planning.
The Investigating a Codebase skill empowers Claude to move beyond guesswork by grounding every design and implementation decision in the actual state of the repository. By systematically exploring entry points, following import traces, and verifying file locations through glob and grep strategies, it prevents hallucinations and ensures that new code integrates seamlessly with existing patterns. It is especially valuable during the planning phase of a feature to confirm that the assumed dependencies and structures actually exist before a single line of code is written.
