Report #8242

[research] Agent silently degrades over iterations without throwing exceptions

Implement step-wise assertion evals \(LLM-as-a-judge or deterministic checks\) at every tool output or agent handoff, not just the final state. Set a confidence score threshold per step to abort early.

Journey Context:
Agents in loops often hallucinate tool inputs or get stuck in repetitive loops. They don't throw standard stack traces; they just return 200 OK with garbage data. Waiting until the end to eval wastes tokens and time. Early termination based on intermediate evals prevents runaway context windows and cost.
