HANDBOOK.md is a benchmark for long-context agentic instruction following, modeled on how enterprise employees follow company handbooks in their day-to-day work. Each task is a unique RL environment with internal tools and external MCP servers, spanning five enterprise domains: Finance, Medical Billing, Insurance, Logistics, and HR.

What it tests

The prompts reflect the actual jobs enterprise workers perform every day. Each task drops an AI agent into a live company environment, requiring them to cross-reference an extensive, multi-section handbook against a cluttered inbox, a multi-channel Slack workspace, Jira queues, and a stack of files (spreadsheets, PDFs), and working out both what to do and what the handbook forbids.

Why it's hard

These policies are written by experts adapting real industry guidelines and are explicitly designed to resist memorization. We created 10 unique base handbooks; every task then modifies its base into a distinct document by changing specific rules and thresholds. Because no two tasks share the same policy, models cannot pattern-match their way through the benchmark. Instead, they must actually read the complex instructions, hold them across a long multi-tool job, and apply them. No frontier model succeeds on more than 25% of tasks.

Overview

agent_harness/ — Agent harness used to evaluate HANDBOOK.md. Built with OpenHands/software-agent-sdk.
docker/ — build context for the handbook base image. Contains mock services and the bundled agent harness.
tasks/ — one subdirectory per benchmark task.
.env.example — template for required environment variables.

Quick start

# 1. Build the base image (build context is self-contained)
docker build -t handbook_base docker/

# 2. Install Harbor + the bundled agent harness into an isolated venv
uv venv .venv --python 3.13
uv pip install --python .venv/bin/python harbor -e ./agent_harness

# 3. Run a single task locally
.venv/bin/harbor run -p tasks/<task_name> \
    --agent-import-path agent_harness.openhands_agent:OpenHandsAgent \
    -m anthropic/claude-opus-4-8 -n 1 \
    --env-file .env
