Key takeaways

  • Evaluate the complete task, not the fluency of an individual answer.
  • Permission boundaries and escalation behavior belong in the score, not in a separate compliance review.
  • Cost and latency must be measured at realistic exception rates and workload volumes.

Start with a task contract

An agent cannot be evaluated against a vague promise to improve productivity. The operating team needs a task contract: the allowed objective, inputs, tools, decisions, completion criteria and conditions that require a human.

The evaluation set should represent ordinary work, difficult edge cases and intentionally ambiguous requests. A system that succeeds only on ideal examples is not ready for a workflow where exceptions create the majority of operational risk.

  • Define an observable completion state.
  • List tools and data the agent may access.
  • Identify irreversible or high-impact actions.
  • Name the human owner of exceptions.

Score five dimensions together

Task success is necessary but insufficient. The same run should be scored for factual support, policy compliance, permission discipline, recovery behavior and resource use.

A weighted aggregate can help compare versions, but it should never hide a failure in a non-negotiable control. An agent that completes a task while exceeding authority has failed regardless of its overall average.

  • Outcome: was the requested state reached?
  • Evidence: are material assertions supported and traceable?
  • Control: did actions stay within policy and permission?
  • Recovery: did the system detect, stop and escalate failure?
  • Economics: what were latency, tool calls and total cost per completed task?

Turn evaluation into a release gate

Evaluation is most useful when attached to change. Model, prompt, retrieval, tool and policy updates should trigger a defined regression suite before deployment.

Production monitoring then checks for drift between the test environment and real work. Incident evidence should feed back into the evaluation set so the control system becomes more representative over time.

  • Version every evaluation set and threshold.
  • Retain representative failure traces without unnecessary personal data.
  • Require named approval for exceptions to release criteria.
  • Review whether business outcomes remain worth the operating cost.

Build an evaluation set that resembles real work

A useful test set is a miniature operating environment, not a collection of polished prompts. It should preserve the distribution of routine cases, missing information, conflicting instructions, unavailable tools and downstream system failures that the agent will meet in production. Teams should also include adversarial cases that attempt to obtain restricted data or persuade the agent to exceed its authority.

Results need to be segmented rather than averaged away. A 95% completion rate says little if failures cluster around one customer group, one language or one irreversible action. Record the task state before and after every run, the evidence consulted, tools invoked, approvals requested and reason for any stop. That trace makes a failed score reproducible and turns incidents into future regression tests.

  • Representative volume and exception mix
  • Separate thresholds for consequential actions
  • Repeatable traces for failed runs
  • Subgroup and language-level error analysis

Connect the scorecard to operating authority

Evaluation should determine what the system is allowed to do. A version may be approved for drafting but not sending, for retrieving but not modifying records, or for recommending a transaction while a named person remains accountable for execution. These bounded release levels create a safer path from assistance to autonomy than a single pass-or-fail label.

The owner should define a rollback trigger before launch: control violations, sustained degradation, abnormal tool use, cost excursions or a class of customer harm. Monitoring then compares production behavior with the approved envelope. When the environment changes, the authorization expires or the evaluation is rerun; it does not silently inherit approval from an earlier model, prompt or workflow.

  • Tie scores to explicit action rights
  • Require approval when tools or data change
  • Predefine rollback and service fallback
  • Review value per correctly completed task
