Summary of Changes
Hello @dmandar, 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 introduces a new protocolVersion field to the AgentCard specification. This change allows agents to explicitly declare the version of the A2A protocol they support, which is crucial for ensuring compatibility and managing future protocol evolution.
Highlights
- Specification Update: The A2A specification documentation (
docs/specification.md) has been updated to formally define the newprotocolVersionfield as a required string in theAgentCardand includes an example of its usage. - gRPC Protocol Definition: The
AgentCardmessage in the gRPC protobuf definition (specification/grpc/a2a.proto) now includes theprotocol_versionfield, ensuring consistency across protocol implementations. - TypeScript Type Definition: The
AgentCardTypeScript interface (types/src/types.ts) has been updated to include theprotocolVersionproperty, complete with JSDoc documentation and an example, providing type safety for clients.

Code Review
This pull request introduces a protocolVersion field to the AgentCard across the specification, Protobuf definitions, and TypeScript types. The changes are consistent and correctly implement the feature. I have one suggestion regarding the field ordering in the Protobuf definition to align with the Google Protobuf Style Guide for better maintainability.
