What do you want to do?

4 use cases

  • Set up gates so agent code stays correct

    Generate contracts, gates, and ratchets for a repo so AI-written code is checked before commit.

    View prompt
    In the repo at <repo-path>, run `/gap-trap setup` after confirming gap-trap is installed with `npx skills add pliablepixels/gap-trap`. Report the list of contracts and gates the skill proposed and the commit it created. Verify that `git status` is clean and that no push happened.

  • Find existing rule violations before they spread

    List current violations by contract and rule in a repo right after setup, without changing code.

    View prompt
    In the repo at <repo-path>, after `/gap-trap setup` has finished, answer yes to the framework check. Return the existing violations grouped by contract and rule. Verify that no files changed by running `git status` before and after.

  • Refine rules after incidents and keep gates current

    Find rules without gates and stale contracts, then turn lessons from commit history into one PR.

    View prompt
    In the repo at <repo-path>, run `/gap-trap refine`. Return the list of rules without gates, stale contracts, and proposed playbook lessons. Verify that each lesson cites a real commit from `git log`.

  • Catch tests that pass against old code in CI

    Run every new test against the old code in CI and fail any test that passes there.

    View prompt
    In the repo at <repo-path>, after gap-trap setup, open a PR that adds one new test. Report the result of the proven red CI job for that PR. Verify that the job ran in CI and not only locally.

How to use Gap Trap

  1. Check you have what it needs: A git repository you want to set up; Claude Code (Opus or better) or Codex (frontier coding model at high reasoning), since the skill stops on smaller models; The skills CLI via npx, or a git clone for a manual install.
  2. Open pliablepixels/gap-trap on GitHub and read the README and license.
  3. npx skills add pliablepixels/gap-trap
  4. Open the target repository in Claude Code or Codex and run /gap-trap setup.
  5. Read the short plan the skill shows (contracts, gates, commands) and answer its questions.
  6. Review each generated contract line by line, since the README says this is the most important review step.

These steps come from our top use case, Set up gates so agent code stays correct, which also has a copy-paste agent prompt.
