5 use cases

  • Gate AI-generated PRs before they merge to main

    Install a workflow that scans agent-written PRs for TODOs, secrets, bad commits and red CI.

    View prompt
    In the repository Akimiya-z/codex-guard style Git repo at <repo-path>, run `npx --yes codex-guard init` and then add and commit .github/workflows/codex-guard.yml. Expected output: the workflow file exists and is staged. Verify that the file contains `uses: Akimiya-z/codex-guard@v1`.

  • Preview gate findings on a local diff before pushing

    Run the Codex Guard CLI on a patch file to see the same checks locally before CI.

    View prompt
    In the repository at <repo-path>, create /tmp/patch.diff from the diff against main and run `npx --yes codex-guard --diff /tmp/patch.diff`. Expected output: a list of TODO, secret and commit findings, or a clean result. Verify that no finding points to a file you did not change.

  • Check a Codex Guard install for config errors

    Run the read-only doctor to find workflow, permission and policy mistakes locally.

    View prompt
    In the repository at <repo-path>, run `npx --yes codex-guard doctor --json` and save the output. Expected output: JSON describing each check as a pass, warning or error. Verify that the command exit code is 0 or 1 and that any error names the file and key involved.

  • Set a per-repo gate policy agents cannot loosen

    Put the policy in .github/codex-guard.yml on the default branch to set blocking rules.

    View prompt
    In the repository at <repo-path>, create .github/codex-guard.yml with `preset: balanced` and `comment-mode: replace`, then run `npx --yes codex-guard doctor`. Expected output: the policy file is accepted with no errors. Verify that the file is on the default branch and not only in a feature branch.

  • Scan every open agent PR in one manual run

    Use the sweep input with workflow_dispatch to check all open agent pull requests at once.

    View prompt
    In the repository at <repo-path>, add a workflow_dispatch trigger and set sweep to true in .github/workflows/codex-guard.yml, then run the workflow manually. Expected output: a report on each open agent PR targeting main. Verify that human-authored PRs without agent markers were not reported.

  2. Open Akimiya-z/codex-guard on GitHub and read the README and license.
  3. Run npx --yes codex-guard init from the root of your Git repository.
  4. Run git add .github/workflows/codex-guard.yml.

These steps come from our top use case, Gate AI-generated PRs before they merge to main, which also has a copy-paste agent prompt.
