About Evaluation Context Protocol (ECP)

ECP is a vendor-neutral JSON-RPC protocol for grading agent outputs, tool calls, and audit context across frameworks, models, and CI systems. ECP gives evaluators a common way to inspect what an agent returned, what tools it used, and what audit evidence it exposed, independent of the framework that built the agent or the platform that runs the test. tool_calls Did the agent call the required tool with the right arguments?. ecp run --manifest Can this run in CI and fail a build?.
