Privileged Information

Summary: Ground-truth data embedded within environment setup scripts that is unavailable to evaluated agents during task execution. This information enables accurate verification of task completion without relying solely on agent self-reporting or visual inspection, serving as a critical evaluation methodology for objective performance measurement.

Overview

Privileged Information represents a fundamental evaluation technique in Computer-Use Agents testing, where verification data is built into the environment infrastructure but kept completely hidden from the agents being evaluated. This approach solves the core challenge of determining whether an agent has genuinely completed a task versus merely claiming completion.

The privileged information is systematically embedded directly into environment setup scripts during the Multi-Agent Environment Creation process within the Gym-Anything framework. When an agent attempts to perform a task, it operates without any access to this ground-truth data, ensuring that evaluation remains objective and prevents agents from simply reading expected outcomes rather than performing actual work.

This methodology proves especially critical for Long-Horizon Task Planning scenarios where tasks require hundreds of interaction steps across complex software interfaces. Manual verification becomes impractical at scale, and visual inspection alone proves insufficient for determining successful completion of intricate software operations spanning multiple applications and workflows.

The privileged information system enables the evaluation of massive benchmarks like CUA-World Benchmark with its 10,103 tasks across 200+ software applications, providing consistent verification standards across all 22 SOC major occupation groups covered in GDP-Grounded Benchmarking.

Key Details

  • Implementation Method: Ground-truth data systematically embedded in environment setup scripts during automated creation process
  • Access Control: Information remains completely invisible to evaluated agents but accessible to verification systems
  • Verification Mechanism: Used by Test-Time Auditing agents to catch premature or incorrect task completion claims
  • Scale Enablement: Supports evaluation of 10,103+ tasks across 200+ software applications without manual oversight
  • Performance Impact: Helps identify when frontier models incorrectly claim task completion, contributing to detection of low pass rates (22.6% for standard tasks, 7.5% for long-horizon tasks)
  • Cross-Domain Application: Functions consistently across diverse software environments spanning all major occupation categories
  • Training vs. Inference: Available during environment setup and verification but never during agent inference, maintaining evaluation integrity
  • Audit Integration: Powers independent audit agents that improve overall system performance by preventing false completion claims

Relationships

  • Automated Verification — privileged information enables systematic verification without human oversight or manual checking
