--- name: pr-writer description: ALWAYS use this skill when creating or updating pull requests — never create or edit a PR directly without it. Follows Sentry conventions for PR titles, descriptions, and issue references. Trigger on any create PR, open PR, submit PR, make PR,... --- # PR Writer Create pull requests following Sentry's engineering practices. **Requires**: GitHub CLI (`gh`) authenticated and available. ## Prerequisites Before creating a PR, ensure all changes are committed. If there are uncommitted changes, run the `sentry-skills:commit` skill first to commit them properly. ```bash # Check for uncommitted changes git status --porcelain ``` If the output shows any uncommitted changes (modified, added, or untracked files that should be included), invoke the `sentry-skills:commit` skill before proceeding. ## Process ### Step 1: Verify Branch State ```bash # Detect the default branch — note the output for use in subsequent commands gh repo view --json defaultBranchRef --jq '.defaultBranchRef.name' ``` ```bash # Check current branch and status (substitute the detected branch name above for BASE) git status git log BASE..HEAD --oneline ``` Ensure: - All changes are committed - Branch is up to date with remote - Changes are rebased on the base branch if needed ### Step 2: Analyze Changes Review what will be included in the PR: ```bash # See all commits that will be in the PR (substitute detected branch name for BASE) git log BASE..HEAD # See the full diff git diff BASE...HEAD ``` Understand the scope and purpose of all changes before writing the description. ### Step 3: Write the PR Description Use this structure for PR descriptions (ignoring any repository PR templates): ```markdown ``` **Do NOT include:** - "Test plan" sections - Checkbox lists of testing steps - Redundant summaries of the diff **Do include:** - Clear explanation of what and why - Links to relevant issues or tickets - Context that isn't obvious from the code - Notes on specific areas that need careful review ### Step 4: Create the PR ```bash gh pr create --draft --title "(): " --body "$(cat <<'EOF' EOF )" ``` **Title format** follows commit conventions: - `feat(scope): Add new feature` - `fix(scope): Fix the bug` - `ref: Refactor something` ## PR Description Examples ### Feature PR ```markdown Add Slack thread replies for alert notifications When an alert is updated or resolved, we now post a reply to the original Slack thread instead of creating a new message. This keeps related notifications grouped and reduces channel noise. Previously considered posting edits to the original message, but threading better preserves the timeline of events and works when the original message is older than Slack's edit window. Refs SENTRY-1234 ``` ### Bug Fix PR ```markdown Handle null response in user API endpoint The user endpoint could return null for soft-deleted accounts, causing dashboard crashes when accessing user properties. This adds a null check and returns a proper 404 response. Found while investigating SENTRY-5678. Fixes SENTRY-5678 ``` ### Refactor PR ```markdown Extract validation logic to shared module Moves duplicate validation code from the alerts, issues, and projects endpoints into a shared validator class. No behavior change. This prepares for adding new validation rules in SENTRY-9999 without duplicating logic across endpoints. ``` ## Issue References Reference issues in the PR body: | Syntax | Effect | |--------|--------| | `Fixes #1234` | Closes GitHub issue on merge | | `Fixes SENTRY-1234` | Closes Sentry issue | | `Refs GH-1234` | Links without closing | | `Refs LINEAR-ABC-123` | Links Linear issue | ## Guidelines - **One PR per feature/fix** - Don't bundle unrelated changes - **Keep PRs reviewable** - Smaller PRs get faster, better reviews - **Explain the why** - Code shows what; description explains why - **Mark WIP early** - Use draft PRs for early feedback ## Editing Existing PRs If you need to update a PR after creation, use `gh api` instead of `gh pr edit`: ```bash # Update PR description gh api -X PATCH repos/{owner}/{repo}/pulls/PR_NUMBER -f body="$(cat <<'EOF' Updated description here EOF )" # Update PR title gh api -X PATCH repos/{owner}/{repo}/pulls/PR_NUMBER -f title='new: Title here' # Update both gh api -X PATCH repos/{owner}/{repo}/pulls/PR_NUMBER \ -f title='new: Title' \ -f body='New description' ``` Note: `gh pr edit` is currently broken due to GitHub's Projects (classic) deprecation. ## References - [Sentry Code Review Guidelines](https://develop.sentry.dev/engineering-practices/code-review/) - [Sentry Commit Messages](https://develop.sentry.dev/engineering-practices/commit-messages/)
