Spec Discrepancy Proposal

Session Tag: [AUTO-SPEC]
Classification: Implementation found a better approach → update spec to match
Priority: High
Source: CHANGELOG.md v3.8.0 (Unreleased)


Discrepancy

The implementation has renamed A2aRequest/A2aResponse fields to standard JSON-RPC 2.0 names (method, id, result, error). The A2aVersionNegotiator handles backward compatibility.

Current spec: The A2A protocol section describes the wire format using CleverAgents-specific field names.

Implementation (merged to master):

  • A2aRequest/A2aResponse fields renamed to standard JSON-RPC 2.0 names: method, id, result, error
  • A2aVersionNegotiator added for backward compatibility
  • This aligns with the JSON-RPC 2.0 standard, which is a better approach for interoperability

Proposed Spec Change

Update the A2A Protocol section in docs/specification.md to:

  1. Document the JSON-RPC 2.0 wire format for A2A messages
  2. Specify the standard field names: jsonrpc: "2.0", method, id, params, result, error
  3. Document the A2aVersionNegotiator for backward compatibility
  4. Note that this aligns with the JSON-RPC 2.0 standard (https://www.jsonrpc.org/specification)

Acceptance Criteria

  • A2A wire format section updated to show JSON-RPC 2.0 envelope structure
  • Field names documented: jsonrpc, method, id, params, result, error
  • A2aVersionNegotiator backward compatibility documented
  • Example request/response payloads updated to use JSON-RPC 2.0 format

Classification

Implementation found a better approach — aligning with JSON-RPC 2.0 standard improves interoperability with external A2A clients. The spec should be updated to match.

Triage Decision [AUTO-OWNR-5]

Verified

Documenting the JSON-RPC 2.0 A2A wire format with the A2aRequest/A2aResponse field rename is a Must Have. The A2A wire format is the core protocol definition for the server implementation (ADR-047). All server implementation work depends on this being correctly specified.

  • Type: Documentation (spec update)
  • MoSCoW: Must Have — core protocol definition required for server implementation
  • Priority: High — server milestone (v3.8.0) implementation depends on this
  • Milestone: v3.8.0
