first-pass is a set of rules, skills and checks for coding agents that makes them review the code around a change, prove their work, and fix bugs as a class.

4 use cases

  • Check your own branch before asking for review

    Run First Pass review on your branch to catch unproven problems before a teammate sees the pull request.

    View prompt
    In the <repo-name> repo, check out branch <branch-name> and run /first-pass:review with nothing after it. Expected output: a list of findings, each with its proof or marked unproven, and what the merge needs. Verify that nothing was posted to GitHub.
  • Fix a bug and every same-pattern copy in one pass

    Reproduce a bug, find the same pattern across the task's scope, and add a check that stops it returning.

    View prompt
    In the <repo-name> repo, use fix-the-class on this bug: <bug-description>. Expected output: a reproduction, the bug class name, every same-pattern hit in the task's scope with its fix or record, and the check added. Verify that the new check fails against the code before the fix.
  • Answer ten pre-code questions before writing a feature

    Have the agent answer ten questions against the real code before it writes a feature.

    View prompt
    In the <repo-name> repo, run premortem on this feature: <feature-request>. Expected output: ten answers covering running twice, stopping halfway, outside service failure, neighbors, endings, money, hostile users, words, scale and time, each as file:line, a test, or Not handled. Verify that each file:line points to code that exists.
  • Run faster checks on a small change

    Switch to quick mode so a small change runs only the checks it can affect.

    View prompt
    In the <repo-name> repo, run /first-pass:quick, make the change described here: <change-description>, then run ship-check. Expected output: a report listing each check run and its result, and which checks were left for a full run. Verify that the report says which CI checks were not run.

How to use First Pass

  1. Check you have what it needs: Claude Code to install the plugin (Cursor and Codex get the rules and skills, but hooks are Claude Code only); A folder that holds your repos, where you start your sessions; Git repos with a branch to review, for the review use case (GitHub access is needed to read pull requests, inferred from the README).
  2. Open joetawil7/first-pass on GitHub and read the README and license.
  3. Run /plugin marketplace add joetawil7/first-pass in Claude Code.
  4. Run /plugin install first-pass@first-pass.
  5. In the folder where you start your sessions, run /first-pass:setup-first-pass.
  6. Check out your branch in the repo, then run /first-pass:review with nothing after it.

These steps come from our top use case, Check your own branch before asking for review, which also has a copy-paste agent prompt.
