Create PR

Make the PR useful to both reviewers and downstream callers. Explain the final behavior, show exact calling changes, and preserve enough source context to audit those claims later. Follow the repository's AGENTS.md and PR template.

Establish the comparison

• Identify the repository, PR or branch, base, and head. Record resolved commit SHAs in the disclosure. Use the actual PR diff, not every change since main.
• For an open PR, compare its merge base with its head. For a merged or historical change, identify the reviewed or landed revision range and state which one you used. Do not infer historical behavior from today's working tree. A commit in Git is not proof of merge or release; use “head revision” unless that status was verified.
• For stacked PRs, distinguish changes introduced here from changes inherited from the base. State dependencies and merge order. Recheck the base after an upstream merge; do not claim independence merely because a PR has its own URL.
• Start with changed files, then inspect definitions, exports, and real callers at both revisions. Use git show, git diff, and targeted rg searches. PR prose and commit messages are context, not proof of an API contract.

Inventory caller-visible changes

Trace each changed contract across the layers that actually expose it: shared Rust types, driver capabilities, auv APIs, CLI arguments, Runner/Proto, and SDKs. Do not scan unrelated modules or invent obligations for untouched layers.

Classify findings as added, removed, changed, or internal-only. Include:

• Exported functions, methods, types, enum variants, fields, and re-exports.
• Parameter order and types, required arguments, defaults, builder options, return values, error categories, and serialization shapes.
• Accepted aliases and values, platform guards, identity or authorization requirements, and resource reuse when existing calls behave differently.

Check these distinctions before describing a migration:

• A new path or re-export is not a removal if the old path still exists.
• A pub(crate) helper rename is not a public API break.
• A new public type does not mean execution methods accept that type. Read their parameter types; show actual accepted inputs, not an intended future API.
• Source compatibility, wire compatibility, and runtime behavior are different. A defaulted wire field can still break Rust struct literals. An older peer can ignore a new field without implementing the requested behavior.
• The ability to parse or compile an input does not prove native delivery.
• An unchanged signature can require migration when defaults, return semantics, lifecycle, or supported platforms change.

Report removals explicitly, including when none were found in the inspected public surfaces. Mention unchanged APIs only when readers could reasonably mistake them for removed or changed APIs. Do not list every untouched method.

Write the disclosure

Lead with the concrete problem and resulting behavior. Use an English Conventional Commit title with the relevant scope. Use chore(docs): ... for primarily documentation changes, as required by this repository. Keep committed PR text in clear, simple English unless the user requests another language.

For API changes, include a Markdown table with side-by-side inline code:

Surface / change	Before	After	Caller action
Rust method — changed	Exact old call	Exact new call	Required migration
Public type — added	Not available	Exact construction or parsing	Optional use or new requirement
Entry point — removed	Exact old call	Supported replacement, or none	Required migration

Replace the illustrative rows with verified findings; omit categories with no rows. Put short code in backticks inside cells. Escape pipe characters as needed for Markdown tables. Put longer compilable examples in fenced blocks below the table and refer to them from the relevant row. Do not put fenced blocks inside table cells. Define receiver types or setup when a snippet would otherwise be ambiguous. Label partial snippets and placeholders; do not imply they were run.

Then add only the migration notes that matter:

• List added APIs with usable examples, and removed APIs with replacements. The comparison table can serve as this inventory; do not duplicate it.
• State required edits versus optional adoption. Preserve platform-specific examples, setup prerequisites, and meaningful before/after behavior differences.
• Name client/Runner version requirements when supported by the code. Do not invent released versions or compatibility negotiation.
• Link each group of claims to commit-pinned source definitions, callers, tests, or durable contract notes. Include both revisions when explaining a removal or signature change. Local revision/path references are acceptable for offline drafts; replace them with permalinks when publishing to GitHub.
• Report validation commands and outcomes at the tested revision. Distinguish compilation, automated tests, live receiver evidence, and pending CI. Do not claim examples were executed when only their signatures were inspected.

For changes with no caller-visible impact, use a short explicit statement and relevant validation instead of an empty table. For a retrospective audit, produce the same disclosure with the historical comparison range; do not create a new PR or rewrite old PRs unless requested. Store a requested durable audit under the owning docs/ai/references/<responsibility>/ directory.

Deliver within the requested scope

Before publishing, compare the final diff with the table and migration notes. Update obsolete rows when scope changes; do not append contradictory follow-ups. Use a structured body argument or gh ... --body-file to preserve code and newlines. Read the published body back to verify it reflects the intended text.

Creating or updating a PR must follow the user's existing authorization. A draft or audit request alone does not authorize publishing, merging, or changing other PRs. When publication is already requested, complete the preparation and publish without an extra confirmation. Keep unrelated working-tree changes out of the PR. The skill does not require raw logs, screenshots, or temporary probe scripts to be committed; concise validation results and source links are sufficient unless the task specifically requires those artifacts.
