Implements robust error handling for Agent-to-Agent (A2A) commerce protocols using JSON-RPC 2.0 standards and domain-specific error codes.

This skill provides specialized guidance for implementing the A2A (Agent-to-Agent) protocol's error handling framework, ensuring reliable communication between autonomous commerce agents. It covers the full spectrum of error management, including standard JSON-RPC 2.0 protocol errors, A2A-specific error codes like TaskNotFoundError, and the critical distinction between protocol-level errors and task-level failure states. By incorporating retry strategies with exponential backoff and graceful degradation patterns, this skill enables developers to build resilient agentic commerce systems that can recover from transient failures and communicate clearly with client applications.
