First Pass

first-pass

first-pass makes a coding agent check the code around a change, not only the lines it
writes, and prove its work before it calls anything done. It's a Claude Code plugin;
Cursor, Codex and other agents get the same rules and skills (the hooks are Claude Code
only). You set it up once, in the folder that holds your repos.

What it does

- Before code, the agent answers ten questions about the change against the real code:
  what happens if it runs twice, stops halfway, or an outside service times out; which
  other code uses the same data; what the user sees when it fails. Each answer is a
  file:line, a test, or a gap you decide to accept.
- While building, anything the task didn't ask for (a helper, a cap, a retry, an option)
  has to earn its place. The agent asks whether it needs to exist, leaves it out when
  nothing requires it, and lists it under "Not built" so you can ask for it. During the
  work, a review finding gets fixed only when it does real harm or stops the change doing its
  job; the rest come to you as one list at the end, to pick from.
- On the task you gave, the agent first writes the task's scope from your prompt and the
  code around it: the feature, everything that uses the same data, the rest of the same
  flow, and the steps that cancel or delete what it creates. Its searches and reviews stay
  inside that scope. A serious problem it happens to see
  elsewhere gets one line in the report (and one in that repo's list of known breaks when it
  breaks one of its rules), and nothing else; anything the change itself breaks
  counts as inside, wherever it is. /first-pass:hulk lifts the
  scope for one task, so it looks everywhere.
- Before "done", a second agent that didn't write the code reviews it in a fresh
  context. "Done" needs a…
