Report #1793

[research] Agent handoffs drop critical context causing downstream agents to hallucinate or fail

Inject a structured handoff summary eval step. Before transferring control, validate that the outgoing agent's context window contains a deterministic JSON schema of required state, and eval the receiving agent's first prompt to ensure it parses this schema correctly.

Journey Context:
When Agent A hands off to Agent B, developers often just pass the raw chat history. Agent B then truncates or misinterprets the history, losing key variables \(like file paths or user constraints\). Passing raw history is brittle. Forcing a structured summary/schema transfer at the handoff boundary makes the handoff stateless and verifiable via schema validation before execution continues.
