What causes repo bloat most often?

Generated output, caches, and local-only files being committed repeatedly are common causes.

Can a .gitignore be too broad?

Yes. Overly broad patterns can hide files your team actually needs to version.

How often should .gitignore be reviewed?

Review it whenever major tooling changes happen, or when noisy files start appearing in commits.

Is a generator still useful for existing repos?

Yes. It is often a good way to rebuild a clean baseline for the current stack.

Gitignore Mistakes That Bloat Your Repo and How to Avoid Them

The Most Common Mistake Is Missing Generated Output

Build folders, caches, temporary exports, package manager artifacts, and generated metadata create noisy repositories quickly when ignore rules do not match the actual toolchain.

Another Problem Is Keeping Outdated Rules Forever

Projects change, but .gitignore files often do not. Old patterns hang around long after tooling changes, while newer generated files slip into commits unnoticed.

Overly Broad Rules Can Also Hurt

A bad .gitignore is not only one that ignores too little. It can also ignore files the team actually needs, creating confusion when expected config or sample files never show up in the repo.

Review Ignore Rules Like Other Build Infrastructure

A .gitignore file supports day-to-day engineering work. It should be reviewed and updated with the same seriousness as build scripts or config files.
