Run five checks before merging AI-written code

Check secrets, unused code, duplication and dependencies, then put repeatable checks in hooks.

Gitleaks, Knip, jscpd, OSV-Scanner and Lefthook cover different parts of a review. Their documentation describes secret detection, unused-code analysis, duplicate-code detection, dependency scanning and Git hooks respectively [1][2][3][4][5].

Scan the repository for secrets

On macOS with Homebrew, Gitleaks documents this installation. Run the scan from your repository [1].

bash
brew install gitleaks
gitleaks git -v

Review each finding before sharing scan output: it can contain the secret that was found [1].

Check unused code and duplication

Follow Knip's setup for your JavaScript or TypeScript project. Review its reported entry points before removing anything it considers unused [2].

For duplication, jscpd documents a one-off scan [3].

bash
npx jscpd .

Use the duplicate locations to inspect the code. Similar text can still serve different behavior.

Scan dependency files

Install OSV-Scanner using its documented installation for your system. Its source scan walks supported package files [4]. Replace the example directory with your checkout.

bash
osv-scanner scan source -r /path/to/your/dir

Keep the useful checks in hooks

Lefthook runs commands you define in lefthook.yml. After configuring those commands, its README installs them into the Git project with [5]:

bash
lefthook install

Keep your application's tests in the review too. These tools report particular problems; a clean scan does not prove the feature works.
