Apply the bundled Google AIPs when designing or reviewing protobuf APIs.

Workflow

Inspect the request and the relevant API definitions.
Search references/catalog.md for the concepts involved. Use rg or another text search instead of loading the entire catalog when possible.
Read only the matching documents from references/aips/{NUMBER}.md, using four-digit numbers such as 0132.md.
Apply the full AIP text, not the catalog preview. Account for each AIP's state and distinguish normative guidance from examples.
When established API precedent conflicts with newer guidance, read AIP-0200 before recommending a deviation.
Cite AIP numbers in the result and separate required changes, recommendations, and intentional deviations.
