Why does a .gitignore matter for security?

It is the first line of defense against accidentally committing .env files with real credentials and bloating the repo with build output.

At minimum .env files (keeping .env.example with placeholders) and node_modules, plus other build and virtual-env directories.

Add a .gitignore that excludes .env* and node_modules, commit it, and run git status to confirm nothing sensitive is tracked.

.gitignore Gaps Check — Does Your Ignore Keep Secrets Out of the Repo?

DevMeth checks the 48 known AI-code failure patterns — not a penetration test or a security guarantee.

What the issue is

A missing or incomplete .gitignore lets secrets and build junk ride into the repo — from .env files to node_modules — bloating it and inviting accidental credential commits.

Why AI tools generate it

AI scaffolds sometimes omit a real .gitignore or ship a trivial one, so generated projects can start ignoring nothing useful.

How DevMeth detects it

A code scan checks that a .gitignore exists and covers .env files (keeping examples) and node_modules, flagging gaps as a hygiene finding.
