# Verification Patterns

> Patterns for evaluating agent behavior and computing scores.

Verification is how an environment evaluates agent behavior and computes a score. Every environment implements some form of verification — the pattern you choose depends on your task.

Compare the agent's output to a known reference answer.

Execute the agent's actions, such as tool calls or generated code, and verify the output or resulting state.

Prompt an LLM to evaluate the agent's output against rubrics, instructions, or reference answers.

Use an LLM trained on human preferences to score outputs for alignment, such as RLHF reward modeling.
