# Rewrite PR Description Regenerate an existing PR's description from scratch. Where the `pr-refresh` skill patches stale content inside the existing structure, this skill discards the old structure and drafts a fresh gold-standard description of the branch's current net change — after mining the old description for context worth carrying forward. User input: $ARGUMENTS ## Context Current branch — run this command and read the output: ```bash git branch --show-current ``` PR for current branch (if any) — run this command and read the output: ```bash gh pr view --json number,title,url,baseRefName 2>/dev/null || echo "(no PR for current branch — expect a PR number/URL in the argument)" ``` --- ## Procedure ### 1. Resolve the PR and its target - If `$ARGUMENTS` contains a PR number or URL, use it; otherwise use the current branch's PR. No PR found → report that and stop (`/pr` handles branches without a PR). - Fetch the full PR: ``` gh pr view <number> --json number,title,body,url,baseRefName,headRefName,state ``` - The diff base is the PR's **`baseRefName`** — stack-aware, never an assumed trunk. Gather the net change: ``` git fetch origin <baseRefName> ``` ``` git log origin/<baseRefName>..HEAD --oneline ``` ``` git diff origin/<baseRefName>...HEAD --stat ``` ``` git diff origin/<baseRefName>...HEAD ``` ### 2. Back up the current description Save the existing body and title verbatim before drafting: ``` mkdir -p .git/pr-backups
