What E2eval does
Eval framework for agents that use real tools against real data. Evals are built from actual tasks — someone asked a question in Slack, debugged a production issue, or traced a config problem through logs and APIs. The agent solves the same task using the same MCP tools: searching messages, querying service catalogs, reading docs, calling internal APIs.
