Eval is not just answer grading
Agent evaluation has to inspect the full task trace, not only the final text response. A good evaluation pipeline checks whether the agent chose the right tools, used the right context, respected constraints, recovered from partial failures, and produced an outcome the user can trust.
Build scenario suites from real risk
The best eval suites are built from real user tasks and known failure modes. Include easy paths, ambiguous requests, tool outages, stale context, permission boundaries, and adversarial-but-realistic inputs. This creates a regression surface that matches the product instead of a generic benchmark.
Connect eval to product decisions
Eval output should drive release gates, alerts, UI warnings, and roadmap decisions. If an eval result cannot change what ships, it is only a report. Coop designs eval pipelines as part of the agentic system, alongside architecture and recovery.

What is an AI agent evaluation pipeline?
It is a repeatable system for testing agent behavior across scenarios, task traces, tool calls, recovery paths, and final outputs before changes reach users.
Why do AI agents need evals?
Agents can fail through planning, tool use, context handling, policy boundaries, or recovery behavior. Evals make those failures visible and prevent regressions.
