# Fix PR Reads review comments, implements fixes, pushes, replies to threads. **Contract doc.** Change mechanics come from the repo's `docs/agents/code-host.md` — read it first if present. The commands below are the **GitHub factory defaults** (`gh`), used verbatim when that doc is absent or confirms GitHub; when it defines a different mechanic for an operation (checkout, read feedback, reply, publish commits), the doc wins. "PR" below means whatever the code host calls a reviewable change. ## Invoke ``` /fix-pr # fixes current branch PR /fix-pr 42 # fixes PR #42 ``` ## Flow ### 1. Identify and check out the PR Get the change metadata — GitHub default: ```bash gh pr view <PR> --json number,title,headRefName,state ``` Refuse if PR is closed or merged. If the current branch is not the PR branch (the /developer pipeline runs this in a fresh worktree), first confirm **where you are**: ```bash git rev-parse --path-format=absolute --git-dir --git-common-dir # two different paths = linked worktree ``` `--path-format=absolute` is not optional: without it git prints whichever form is shortest from your cwd, so from a subdirectory of the primary checkout the two answers differ (`/abs/path/.git` vs `../.git`) and the check reads a primary checkout as a worktree. As a /developer worker you must be in a linked worktree; if both paths are equal you are in the user's primary checkout — do not check anything out, end with `RESULT blocked reason=escaped worktree`.
