Technical topic
AI agent evaluation
Task portfolios, trace grading, simulation, red teaming, stochastic reliability, and production quality gates.
Direct answer
AI agent evaluation tests representative task families across repeated trials, grades both outcomes and consequential traces, and treats serious failures separately from average scores. A production gate also needs reproducible environments, adversarial cases, domain review, rollout limits, monitoring, and rollback rather than one golden dataset or headline benchmark.
What this topic helps you decide
AI agent benchmarks
Build a versioned task portfolio that represents real workflows, edge cases, and consequence levels.
Outcome and trace grading
Check the final result and the tool, evidence, policy, and side-effect path used to reach it.
Production quality gates
Translate repeated evaluation evidence into release, canary, monitoring, and rollback decisions.
Practical questions answered
- Why is a golden dataset not enough for agent evaluation?
A measurement-contract approach that extends reference answers with environment state, tool trajectories, permissions, budgets, uncertainty, and serious failures.
- How do I build a task portfolio instead of a benchmark shrine?
A versioned portfolio method that represents task families, users, frequency, risk, difficulty, tools, environments, and changing production failures.
- What makes an agent test environment reproducible?
A versioned environment manifest for agent tests with controlled state, time, identity, tools, dependencies, faults, resets, and observations.
- Should I grade the final outcome or the agent trace?
A grader design that makes verified outcomes primary while using trace checks selectively for policy, safety, evidence, and diagnosis.
- How many trials does a stochastic agent evaluation need?
A decision-driven trial plan using uncertainty, task slices, correlated runs, serious failures, stopping rules, and paired comparisons.
- How can I simulate users without fooling myself?
A validation card for agent-evaluation user simulators covering persona distributions, hidden goals, behavior calibration, leakage, and transfer to real users.
- How do I turn agent evaluation results into a production quality gate?
A versioned quality-gate record with predefined thresholds, serious failures, uncertainty, exceptions, owners, canary evidence, rollback, and expiry.
