[research] Multi-agent handoffs lose context or hallucinate state

Evaluate intermediate steps \(traces\), not just final outputs. Inject assertions at the handoff boundaries between agents to ensure the payload passed matches the expected schema and contains necessary context, dropping irrelevant state.

Journey Context:
Evaluating only the final output of a multi-agent system makes debugging impossible; a failure at step 2 cascades into an opaque failure at step 5. People often try to fix this by adding more context to the initial prompt, causing bloat. The right call is trace-level evaluation \(step-by-step\) to isolate which agent or handoff introduced the error. This allows fixing the specific agent's system prompt or tool definition rather than guessing.
