HANDBOOK.md

HANDBOOK.md is a benchmark for how well a model acts as a general-purpose agent. The official description says: "Official OpenHands-based harness using tasks from the benchmark's early open-source v1 release". Below we describe in simple words what benchmarks of this type generally examine.

HANDBOOK.md measures how well a model acts as a general-purpose agent. In detail, it checks:

• solving long, multi-step tasks with many intermediate decisions
• using tools correctly (browsers, terminals, APIs, calendars, other apps)
• adapting when something unexpected happens mid-task
• staying on goal over long task horizons instead of wandering off

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.

What does HANDBOOK.md test?

HANDBOOK.md mainly measures how well a model acts as a general-purpose agent. Concretely, it checks: solving long, multi-step tasks with many intermediate decisions; using tools correctly (browsers, terminals, APIs, calendars, other apps); adapting when something unexpected happens mid-task.

How is the HANDBOOK.md score calculated?

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better. The declared maximum score of this benchmark is 100.0.
