name: pr description: >- Create or update a pull request for the current branch. Trigger when the user asks to create/open/make a PR, or to edit/update/rewrite/fix the PR description, body, or summary — for both new PRs (gh pr create) and existing ones (gh pr edit --body-file). Use for any verb that lands on a PR's text content: "open a PR", "make a PR", "update the PR description", "rewrite the PR body", "fix the description". allowed-tools: Bash, Read, Glob, Grep

Pull request workflow

Create or update a pull request for the current branch.

Workflow

1. Gather branch state

Run in parallel:

• git status (no -uall)
• git diff main...HEAD --stat
• git diff main...HEAD --name-only
• git log main..HEAD --oneline
• EXISTING_PR=$(gh pr view --json number,url,title 2>/dev/null) — capture for step 2.

If the branch has no commits ahead of main, stop and tell the user.

2. Build the summary body and create/update the PR

Write a summary of the change (2–5 bullets based on the diff and recent commits) to a temp file. Follow the repo's existing PR body style — look at the last few merged PRs (gh pr list --state merged --limit 5 --json body,title) to match tone and length. Keep the title under ~70 chars.

Bias toward brevity. Reviewers skim. A bullet that fits on one line beats one that wraps three times — push detail down to the diff or commit log, not the body. If a per-file bullet starts feeling like an essay, compress to a single sentence naming the kind of change (e.g., "tightened description, trimmed unused allowed-tools, consolidated duplicated snippets") rather than enumerating each edit. Aim for under ~6 bullets total across the whole body, including any nested ones; if you're past that, regroup by category until you fit.

Describe the end state, not the journey. Reviewers want to know what the PR does now — the diff that will land — not the order in which it was built. Avoid framings like "first pass" / "second pass", commit-hash references for stages of work that all merge into the same shipped diff, "originally we tried X then switched to Y", or play-by-play of how the conversation evolved. The git log preserves that. If a discarded approach is genuinely load-bearing context for the reviewer (e.g., explains why the chosen approach is structured oddly), one line is enough; otherwise omit. The same applies when updating an existing PR body: rewrite to describe the current diff, don't append a changelog of edits made since the last revision.

No "Test plan" section unless the user asks. Don't list things CI already covers (e.g. bundle exec rspec). Those belong to CI, not the PR body. Only add a Test plan when there's reviewer-facing manual verification a human needs to do, and only when the user requests it.

No Claude Code attribution footer. Don't append the "🤖 Generated with Claude Code" line (or any variant of it) to the body. The PR body should read like the human author wrote it.

Push the branch: git push -u origin HEAD.

• If $EXISTING_PR from step 1 was non-empty: gh pr edit <num> --body-file <tmp-body-file> (don't overwrite the title unless the user asks).
• Otherwise: gh pr create --draft --base main --title "..." --body-file <tmp-body-file>. Create as a draft by default; only omit --draft (or mark ready) if the user explicitly asks for a ready-for-review PR. Capture the PR number from the output.

Always pass the body via --body-file (not inline --body) to preserve formatting.

Return the PR URL.
