About
Codebase Recon is a specialized capability for Claude Code designed to transform how developers explore and understand unfamiliar or complex software systems. Instead of relying on guesswork, this skill implements a rigorous investigation framework that gathers evidence from source code, documentation, test suites, and version history. It utilizes a unique confidence-tracking system (Levels 0-5) to communicate the certainty of its findings, making it an essential tool for onboarding to new projects, conducting technical audits, and identifying architectural patterns before implementing major changes.
