Code health
Codebase hygiene
Codebase hygiene is the day-to-day maintainability of a repository: clear structure, low duplication, working checks, current dependencies, and patterns that future changes can follow.
What it means
Codebase hygiene is the practical condition of the repository. It covers whether files are organized, tests are usable, dependencies are understandable, and repeated patterns make future work easier instead of harder.
Why it matters for AI-written code
Agents tend to continue the patterns they see. A messy project teaches messy future changes, while a healthy project gives the next agent a clearer path through the code.
Guard and Fleet context
Guard treats codebase hygiene as a maintained health signal. It is not a one-time cleanup project; it is one of the areas recurring audits keep watching as the repository changes.
How Enji Guard helps
Guard identifies hygiene issues that slow change, explains why they matter, and prepares safe improvements when the fix is narrow enough for a reviewer to trust.
