pydantic-ai: Skill for Claude Code

Address PR Review Feedback

Find and address all review comments on the PR for the current branch. For each comment:

1. Gather context: Use gh to find the PR number from the current branch, then fetch all unresolved review comments (both PR-level and inline review comments via gh api repos/{owner}/{repo}/pulls/{number}/comments). Skip already-resolved and outdated threads. Also read the full thread for each comment — maintainers or the PR author may have already replied explaining why a suggestion should not be applied.

2. Triage each comment: A review comment — bot or human — is evidence to weigh, never an acceptance criterion. This PR's acceptance criteria are its linked issue, the repository instructions, and settled maintainer decisions. Sort each comment into fix, decline, escalate or file; one that clears the gates below is a fix.

   • Read the thread first. If a maintainer has already weighed in, that settles it; your own earlier reply does not.
   • If the finding claims a defect, reproduce it before you write the fix. Run a script, a failing test, or a snippet. A plausible reading is not a reproduction, and a severity label is the reviewer's guess. If it doesn't reproduce, reply with what you ran and why that run covers the path the finding names, then react 👎. A repro you could not run — no credentials, no worker, no cassette — is not a refutation: ask the user driving you instead. A finding about docs, tests, naming, or API shape has nothing to reproduce; weigh it against the repository instructions.
   • List the production files the fix would touch. A file outside the ones this PR already changes for its issue — a shared core module especially (pydantic_ai/_agent_graph.py, pydantic_ai/_run_context.py, pydantic_ai/messages.py, pydantic_ai/tools.py, a base class, a serialized dataclass) — means the finding has outgrown the PR's stated scope. Implement it here only on the root AGENTS.md bar for the case at hand — a sibling field, provider or model needs the same defect reproduced there; a shared protocol, helper or abstraction needs the narrow fix to be unavailable, or the refactor to be itself the confirmed fix — and only when including it neither explodes scope nor delays an already mergeable PR. Otherwise escalate it per pushing-commits-to-the-repo ("Escalate real trade-offs, don't guess") when it needs a maintainer decision, or file it as its own issue when it is real but belongs elsewhere. Tests and documentation this change already owes are in scope, not an expansion.
   • Name who else moves. If the users whose observable behavior changes are a wider set than the users who hit the reported bug, the finding breaks the root AGENTS.md requirement to "leave behavior unchanged for users who aren't hitting the problem you are solving". Re-scope or escalate; never implement and document.
   • Ask the user driving you when the call is a preference they may hold. A finding can be wrong on the merits wherever it sits: decline that one with code evidence, per pushing-commits-to-the-repo ("Invalid"), rather than filing it.

3. Fix the code: Make the changes for each comment triage sent to fix.

4. Continue the PR loop: Follow pushing-commits-to-the-repo from its Before you push section.

5. Use the canonical close-out: Apply every required reply, reaction, and resolution step from that workflow. For each completed comment, explain what changed or why no change was needed. Then resolve the thread via GraphQL resolveReviewThread. Leave threads open only when a decision or another person's response is pending.

Always read the relevant code before making changes.

Important: Automated reviewers surface real issues and are never skipped — every finding gets a reply and a reaction. But a bot cannot approve a scope expansion, and its severity label carries no authority. A HIGH on a defect that does not reproduce is a 👎. Refuting one leaves CI Review's REQUEST_CHANGES standing; a later push re-runs the review, and the verdict clears only if that run stops finding the HIGH. Say so when you hand the PR back.
