EVALS.md
Agent evaluation system
Define representative tasks, outcomes, failure taxonomies, graders, human review, operational metrics, release thresholds, and regression processes for behavior that varies across models and environments.
Fillable structure
Replace prompts with project evidence.
Remove any field that does not apply. A smaller maintained file is more useful than generic documentation that agents and reviewers cannot trust.
- 01
Outcomes and failure taxonomy
Measure the behavior that matters instead of a convenient proxy.
Success: Define task completion, quality, safety, latency, cost, and user-correction outcomes
Failures: Classify instruction, context, reasoning, tool, authorization, data, and recovery failures
Severity: Define critical, major, minor, and acceptable variance with examples
- 02
Evaluation set
Represent normal use, boundaries, adversarial cases, and longitudinal behavior.
Cases: List source, owner, input, expected evidence, and protected data classification
Coverage: Map cases to requirements, tools, users, languages, failures, and risk levels
Versioning: Define frozen sets, hidden sets, additions from incidents, and contamination controls
- 03
Graders and metrics
Make every score interpretable and periodically calibrate judgment.
Deterministic checks: List schemas, exact properties, tests, policy checks, and artifact inspection
Judgment: Define rubric, human reviewers, model graders, blind review, and disagreement handling
Operational metrics: Track completion, correction, retries, tool errors, latency, tokens, cost, and abandonment
- 04
Release and regression
Turn evaluation into a shipping control rather than a report.
Thresholds: Define minimums, critical-case zero tolerance, confidence, and comparison baseline
Release gate: State when a change blocks, warns, rolls out gradually, or requires sign-off
Regression loop: Add incidents and user corrections, assign owners, and verify fixes across supported models
