feat!: update a2a.proto 0572953 #606

jmesnil · 2026-01-22T14:45:36Z

based on commit a2aproject/A2A@0572953

spec-grpc module has been regenerated from the updated a2a.proto

Key changes:

Agent card
- extendedAgentCard is not specified by capabilities (instead of supportsExtendedAgentCard field)
- protocolVersions is a list (instead of a single protocolVersion)
SendMessage
- msg field is now named message
ListTask
- timestamp is now named statusTimestampAfter instead of lastUpdatedAfter
OAuthFlows
- deviceCode has been added, implicit & password have been removed
AuthorizationCodeOAuthFlow
- new pkce_required boolean field

There is no change regarding them in the updated a2a.proto.
The ListTaskPushNotificationConfigParams record has them:

What would be missing?

@jmesnil sorry, I read the code too quickly.

Code Review

This pull request updates the a2a.proto definition and regenerates the spec-grpc module, leading to several API and internal changes across the client and server implementations. Key updates include renaming the msg field to message in various message types, changing lastUpdatedAfter to statusTimestampAfter in task listing parameters, and modifying the agent card's protocol version field from a single string to a list of strings (protocolVersions). Additionally, OAuth flows have been updated to remove implicit and password flows in favor of a new deviceCode flow, and a pkce_required field has been added to the AuthorizationCodeOAuthFlow. The extended agent card retrieval mechanism has also been refactored to align with these protocol changes. A minor redundancy was found in the JsonMessages.java test file where extendedAgentCard was listed twice in the capabilities object.

Summary of Changes

This pull request incorporates significant updates to the core a2a.proto definition, leading to a comprehensive regeneration of the spec-grpc modules. These changes refine the Agent Card's capabilities, standardize message field names, enhance task filtering options, and modernize OAuth flow configurations. The modifications aim to improve the protocol's robustness, security, and alignment with current best practices, with corresponding updates propagated throughout the client and server implementations.

Highlights

Agent Card Structure Updates: The Agent Card now specifies extendedAgentCard within its capabilities, replacing the standalone supportsExtendedAgentCard field. Additionally, protocolVersions is now a list, allowing for multiple supported protocol versions instead of a single protocolVersion string.
Message Field Renaming: The msg field in SendMessage requests and responses has been consistently renamed to message for improved clarity across the API.
Task Listing Parameter Change: The task listing parameter lastUpdatedAfter has been renamed to statusTimestampAfter and its type updated to google.protobuf.Timestamp for more precise filtering of tasks based on their status update timestamps.
OAuth Flow Modernization: The OAuthFlows configuration has been updated to remove the less secure implicit and password flows, and introduces a new deviceCode flow. The AuthorizationCodeOAuthFlow also gains a pkce_required boolean field to indicate mandatory PKCE usage.
Client and Server Implementation Alignment: Client-side code (Java base, gRPC, JSON-RPC, REST transports) and server-side components (request handlers, Quarkus integrations) have been updated to reflect these a2a.proto changes, including method renames, parameter adjustments, and error handling for the new ExtendedAgentCardNotConfiguredError.
