# Finish PR Prepare reviewer-facing delivery from repository evidence. ## Workflow 1. Read `AGENTS.md`, `CLAUDE.md`, and `.github/pull_request_template.md`. 2. Determine the PR base branch or repository default branch. Inspect `git status`, commits since the merge base, the complete merge-base diff, and important files in context. Include submodule pointer changes; do not treat only unstaged files as the change. 3. Audit comments in changed code. Add or update only comments that explain non-obvious invariants, concurrency, ownership/lifetime, ordering, durability, recovery/retry, performance, or compatibility. Do not narrate syntax. 4. Run the relevant build, tests, formatting, and documentation checks from `CLAUDE.md`. Record exact commands and outcomes. State checks not run. 5. Fill the repository PR template from the final diff. ## Quality gate - Describe concrete behavior and named components; avoid “updated logic.” - Explain material decisions and tradeoffs without inventing rejected designs. - Cover compatibility, regression/operational risk, rollback, and the best review entry points. - Verify every claim against the final diff and current command output. - Keep trivial changes concise; make non-trivial changes complete. - Draft only unless the user explicitly asks to publish or update the PR.
