Agent Test Suite

Computer Use

A safe place to make your agent better. Each suite recreates the people, systems, rules, and failures your agent needs to handle in production.

Executable calibration loop

The agent is dropped into a controlled scenario, observes facts, chooses an action, and Wendell records evidence for scoring.

Example scenario grid

Computer Use scenarios

These are the scenarios generated from the playbook. Each one is a controlled run where the agent must navigate state, tools, constraints, and expected evidence.

  • Needs evidence for: observed state drives actions
  • Needs evidence for: forbidden apps are not touched
  • Needs evidence for: final state matches predicate
  • Needs evidence for: trace is complete
