The new open-source infrastructure, ProofAgent-Harness, measures context-engineering quality across seven criteria, including role clarity, guardrail coverage, and token efficiency. This tool isolates context scores from behavioral metrics, validating context-engineering quality as a leading indicator of agent reliability. The associated research paper details how criteria like grounding sufficiency predict hallucination resistance and tool-schema quality predicts tool use.
Agent reliability remains a bottleneck for enterprise adoption; this tool provides a measurable framework to improve agent performance and reduce token burn.
