Report #72412

[frontier] When my agent delegates a task to a remote specialized agent, the second agent loses file context and previous conversation history, producing incorrect results.

Implement A2A Task Delegation: use the Google A2A protocol to create a Task object containing Artifacts \(files, context\) and State \(conversation history\), send it to the remote agent's agent.json endpoint, and receive updated Artifacts and status updates asynchronously.

Journey Context:
Ad-hoc agent delegation passes only text instructions, losing file attachments and binary data like images or PDFs. The Google A2A protocol \(April 2025\) treats tasks as stateful objects with artifact payloads, similar to email with attachments but for machine agents. Key insight: agents need to pass 'files' and 'session state' not just chat history—imagine a coding agent spawning a security scanner with the actual codebase files, not just descriptions. This enables 'swarm' patterns where specialized agents \(tester, reviewer, implementer\) pass actual code artifacts between them. Tradeoff: requires serialization of complex state objects and handling of binary data encodings. Essential for enterprise multi-agent systems where different vendors' agents must collaborate on document processing or software engineering tasks.
