Build A2A Protocol Communication Layer

Inspect the original prompt language first, then copy or adapt it once you know how it fits your workflow.

Implement a simplified Agent-to-Agent (A2A) Protocol for your agents to communicate effectively within the LangGraph workflow. Define message structures (e.g., query, response, command, status) and a mechanism for agents to securely exchange information and coordinate tasks.

Adaptation plan

Keep the source stable, then change the prompt in a predictable order so the next run is easier to evaluate.

Keep stable

Hold the task contract and output shape stable so generated implementations remain comparable.

Tune next

Update libraries, interfaces, and environment assumptions to match the stack you actually run.

Verify after

Test failure handling, edge cases, and any code paths that depend on hidden context or secrets.
