fix(spec)!: Switch to non-complex IDs in requests by Tehsmash · Pull Request #1389 · a2aproject/A2A

Tehsmash · 2026-01-20T16:21:18Z

Some operations like GetTask / SubscribeToTask still used complex / compound identifiers like tasks/<uuid> which requires the clients/servers to deconstruct/construct these IDs as they are normally using just the UUID to store the resource in the DB etc.

This commit refactors them so they are just the IDs, in some cases this meant that we needed to split one field into two i.e. parent + name.

Fixes: #1390

Summary of Changes

Hello @Tehsmash, 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 refactors the gRPC API specification to streamline resource identification within requests. By transitioning from complex, compound identifiers to simpler, non-complex IDs, the change aims to reduce the overhead of deconstructing and constructing these identifiers on both client and server sides, thereby simplifying API interactions and data handling.

Highlights

Simplified Resource Identifiers: Request messages now use non-complex IDs (e.g., UUIDs) instead of compound resource names like 'tasks/', reducing client-side parsing.
Split Compound ID Fields: For operations like GetTaskPushNotificationConfig and DeleteTaskPushNotificationConfig, a single compound 'name' field has been logically split into distinct 'parent' and 'name' fields.
Updated API Path Definitions: HTTP path templates in the .proto file have been adjusted to explicitly include resource types (e.g., '/tasks/') while referencing the simplified ID fields.
Enhanced Field Clarity and Requirements: Comments for ID fields have been updated, and several 'name' and 'parent' fields are now explicitly marked as REQUIRED.

Code Review

This pull request refactors several RPCs to use simple, non-complex resource IDs in requests, which is a great improvement for API usability. The changes to HTTP path templates and request messages are consistent and well-executed. I've added a couple of minor suggestions to improve comment clarity and ensure consistency in field requirements across all updated messages. Overall, this is a solid refactoring.

Can we use more readable names for these parameters like taskId and configId instead of parent and name ?

From TSC. We will be renaming the parameters so as not to confuse AIP folks into thinking name is a complete resource name.

Do we have to vote ? @darrelmiller @ToddSegal @amye ? I see PR review approvals but not as many votes.
