secret-handling

To prevent credentials from leaking into git commits, implement a pre-commit validation check that blocks secret reads and replaces credentials with placeholders in committed outputs.

The best way to stop agents from reading .env files is to enforce a strict policy that prohibits reading sensitive files and suggests safe alternatives like .env.example.

Secret leak prevention in CI pipelines works by enforcing prohibitions on reading production env files and blocking any credentials from being written to committed outputs during automation.

You need a pre-commit hook to protect secrets in your repository because it actively blocks .env reads and validates outputs, ensuring credentials are replaced with placeholders before code is committed.

You should use .env.example instead of .env because it provides placeholder guidance for required variables without exposing actual production credentials, ensuring safe handling during development.

You can automate credential security checks across code repositories by applying policy enforcement rules that block reads of sensitive files and validate committed outputs before changes are finalized.
