Benchmark Environment

Software componentObservability & EvaluationObservability & EvaluationVariation point (abstract)arc:BenchmarkEnvironment

An interactive, reproducible task environment (e.g., operating system shell, database, knowledge graph, web application, game) that exposes actions and state to an agent under evaluation over multi-turn episodes.

Responsibility. Provides a controlled interactive world in which an agent's multi-turn task performance is measured.

Also known as: Evaluation environment, Benchmark environment adapter, Testing environment

is invoked by dependency

Design guidance

SHOULD be standardized and version-controlled, with fixed snapshots for regression testing and documented dependencies.
SHOULD be provisioned by automated setup and updated deliberately rather than allowed to drift silently.

Quantitative guidance

As stated by the sources; verify before use.

AgentBench OS tasks require ~10-20 commands; hard tasks generate 4,000-13,000 tokens (dev avg 4,000, test avg 13,000) (Ch3.2).
WebArena requires deploying four web applications (e-commerce, forums, code collaboration, CMS) (Ch3.2).
