Summary of Changes
Hello @a2a-bot, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request, automatically generated by a2a-bot, synchronizes the Python protobuf definitions with the most recent A2A specification. The primary functional change involves renaming several fields within existing message types to ensure consistency with the updated schema.
Highlights
- Type Synchronization: The A2A Python protobuf types have been updated to align with the latest A2A specification (
specification/json/a2a.json). - Schema Field Renames: Specific fields within the protobuf schema have been renamed: the
updatefield inTaskStatusis nowmessage, and themsgfield in bothSendMessageResponseandStreamResponseis also nowmessage. - Automated Generation: The
src/a2a/grpc/a2a_pb2.pyfile was regenerated by an automated bot to reflect these schema changes.

Code Review
This pull request updates the A2A protocol buffer definitions based on the latest specification. While the generated protobuf file (a2a_pb2.py) is correctly updated, this has introduced breaking changes by renaming some fields. The rest of the codebase that consumes these protobuf messages, including the type stubs (.pyi) and utility functions, has not been updated accordingly. This will lead to runtime errors. I've left a critical comment detailing the required changes in other files.
