Report #1342

[research] Agent context gets corrupted or lost during multi-step handoffs and tool calls

Inject state assertions at trace boundaries. Instead of only evaluating the final output, write evals that intercept the trace at each handoff \(e.g., Planner -> Coder\) and validate the payload against a schema or intent checklist before the next step executes.

Journey Context:
Multi-agent systems or complex agentic loops suffer from the telephone game. The planner outputs a plan, but the coder misinterprets a parameter. The final output fails, and the error is blamed on the coder, when it was actually a handoff ambiguity. Evaluating only the final result makes debugging exponentially harder. By evaluating intermediate traces, you localize the failure point immediately. This requires instrumenting the agent runtime to emit structured events and running evals against these intermediate spans.
