Pushing starts a loop; it does not end the task. Work stops only when CI is green AND no comment is left unresolved.

When you open the PR

Write the title and body

Follow the title and template rules in the root AGENTS.md.

Keep visible body content within 40 lines. Exclude template lines and collapsed <details> contents from the count. For a feature or behavior change, use this order:

1. Why we make these changes — State the problem and decision in a few sentences. Link the issue.
2. New public surface — List each new maintained symbol. Write none when there is none.
3. User-visible behavior — Show the smallest before-and-after example. Replace it with a call-path diff when the changed call chain explains the behavior; do not include both.
4. Verification — Link the exact proving tests from the PR diff. Put a minimal runnable playground in <details> only when it helps reviewers reproduce the behavior.
5. What changes for existing users — State the effect in one sentence. Nothing is valid.

Use one collapsed <details> section per goal only when the PR has multiple independent goals. For a trivial PR, use the issue link, a short summary, and the test plan.

User-visible call-path diff

Use one fenced diff tree from the public entry point to the changed observable result.

• Format each node as path/file.py :: Class.method() or path/file.py :: function().
• Indent each callee beneath its caller with └─. Preserve enough unchanged nodes to show each edge.
• Collapse irrelevant intermediate calls as … unchanged machinery ….
• Include arguments only when they explain the change.
• Include results only on relevant leaves.
• Keep the shared caller prefix unmarked. Mark only diverging nodes, relevant arguments, or results.
• Target 12 content lines inside the fence. Never exceed 20; collapse secondary branches instead.

Apply a label — the repo triages and filters by them. Fetch the real list first with gh label list --limit 100, because the set changes and a guessed label silently fails to apply. Pick the one naming what the PR is (bug, feature, docs, chore, refactor) and add a topic label (anthropic, MCP, evals, …) where one fits: gh pr edit <number> --add-label <label>.

Labelling needs triage permission on the repo (Pydantic team members and their agents). If it fails, quote the actual error rather than concluding you lack permission. Size labels are applied automatically — don't set them.

Before you push

• Commit the exact state you intend to push. Leave nothing staged, unstaged or uncommitted unless the user's instructions override this.
• Run pre-push-review. Address every finding, commit the fixes, and repeat the review until it returns no findings. This applies before the first PR push and between every later PR iteration.
• Never force-push an open PR branch. Push follow-up commits so previous reviews remain valid; maintainers can squash them when merging.
• Attempt the push. If it fails, read the real error — do not preemptively decide you lack permission from a flag or setting.

After you push — the loop

1. Watch CI to a terminal state. Don't idle. If it fails, diagnose: fix if the failure is yours; if it's a known flake or pre-existing on main, say so with evidence.
2. Triage every comment (bots and humans alike). For each one:
   • Valid → fix it, then reply saying what changed, and react 👍.
   • Invalid → reply explaining concretely why (with code evidence), and react 👎.
   • Never silently ignore a comment, and never resolve a thread without a reply.
3. Escalate real trade-offs, don't guess. If a comment needs a maintainer decision (a design choice, an API trade-off, a behavioral default), leave a comment containing: the background, your reasoning, the decision that needs making, the trade-offs (pros/cons of each option), and your recommendation. Then poll every 30 minutes for a reply and continue when it lands.
4. Repeat until CI is green and no comment is outstanding.

When the loop completes — consider a deep douwebot review

The repo has two standards reviewers, and they are independent:

• CI Review runs automatically once the CI workflow succeeds on the PR's current head. It owns the APPROVE/REQUEST_CHANGES verdict and has the more rigorous process — severity scale, sub-agent fan-out, per-finding verification.
• douwebot runs only when the douwebot label is applied, on a stronger model. It posts inline comments and no verdict, and it deletes the label when it finishes, so each application buys exactly one review of the diff as it stands at that moment.

Applying the label adds a second opinion; it does not suppress or replace CI Review.

Once the loop above has terminated — CI green, every comment triaged — decide whether to apply it before handing the PR back or requesting merge:

• Apply it last, not early. It won't re-run on later pushes, so a deep review of a still-moving PR is wasted money.
• Use judgment on whether it's warranted. Skip it when you're highly confident there's nothing left to catch (typo fixes, dependency bumps, mechanical chores). Apply it for substantive changes: new features, behavior changes, public API surface, non-trivial bug fixes — and user-facing docs, where it catches things like examples using outdated models. In between, weigh cost against risk; smaller PRs are cheaper to review, so lean toward applying when unsure.
• How: gh pr edit <number> --add-label douwebot. This requires triage permission on the repo (Pydantic team members and their agents). If it fails, quote the actual error — don't skip it based on an assumed lack of permission.
• Known refusal: the job fails without reviewing if the PR touches AGENTS.md, CLAUDE.md, or anything under .claude/ — a security guard against a PR editing the reviewer's own instructions. Don't apply the label to those PRs; the red check is the guard working.
• Afterwards, re-enter the loop. The review posts comments that need the same triage as any other.

Before handing the PR back

Run this final metadata check after CI, comments, and any selected douwebot review have settled:

1. Dispatch a fresh subagent that has not worked on the PR.
2. Give it the PR URL, linked issue, current base...HEAD diff, final test status, title, and body.
3. Ask it to check only the title and body against this section and the root AGENTS.md.
4. Require either current or an exact replacement title and body.
5. Apply every correction. Code changes restart the post-push loop; metadata-only changes do not.
6. After a replacement, repeat the check with another fresh subagent.
7. Hand the PR back only after the check reports current.
8. Report the human-only AI-code checkbox separately.
