A structured repository review for teams that need clarity before changing a mature system.
Direct answer
A codebase audit is a structured review of a repository that identifies technical debt, security issues, architectural bottlenecks, dependency risk, and maintainability problems so a team can plan safer changes.
A useful audit should explain what the product does, who the codebase is risky for, which modules are hardest to change, what technical debt patterns exist, and what concrete remediation steps would reduce delivery risk fastest.
Teams usually request a codebase audit before a rewrite, acquisition, team handoff, or large modernization initiative. The audit reduces guesswork and helps separate urgent structural risk from ordinary cleanup.
AI code review often comments on diffs or local snippets. A codebase audit works at repository scale and is better for understanding systemic issues like ownership concentration, tangled modules, and cumulative technical debt.
