Fidelity Is Not Enough: Dispatch-Level Instrumentation for Agentic Datasheet Extraction

This is the kind of debugging trap that catches real systems: the model appears to work on the fidelity check but never actually called the tool it was supposed to. The dispatch-level trace is the only way to catch it. For anyone building document extraction or other structured-output agents, this is a pattern you need now. Stop trusting fidelity alone; instrument the tool calls.

Diagnosing with Insights: Structured Analysis of Agent Failures via Behavioral Abstractions

Agent debugging is a real friction point right now, and this addresses it with a concrete system. The approach of using structured abstractions plus neural invariants is cleaner than pure LLM-as-judge diagnosis. If you're shipping agents in production and drowning in opaque failure logs, this method deserves a test run. It won't solve everything, but it's directional.
