openbench CLAUDE.md

Repository instructions for OpenBench, a Python project for running and developing benchmarks, which are repeatable tests used to compare systems. They cover virtual-environment setup, dependency management with UV, tests, code checks, and the command-line interface.

In plain words
What is it for?
They help create the environment, install dependencies, run unit and integration tests, check formatting and types, run pre-commit checks, and list available benchmarks.
Why use it?
They provide the project's required setup and quality rules, helping developers avoid using the wrong package manager or running commands outside the expected environment.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

openbench CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Essential Setup

  • Always source the virtual environment before running Python commands: source .venv/bin/activate
  • This project uses UV as the package manager, not pip
  • Dependency management: When adding dependencies with UV, use >= constraints (e.g., uv add "package>=1.2.3")
    • Exception: inspect-ai must remain pinned to a specific version for stability
    • Use the latest stable version as the minimum to keep dependencies healthy and secure
    • Check latest versions with uv pip list --outdated or on PyPI

Key Commands

Development Setup

# Initial setup
uv venv && uv sync --dev
source .venv/bin/activate

Running Tests

# Run all unit tests
pytest

# Run integration tests (requires API keys)
pytest -m integration

# Run specific test file
pytest tests/test_registry.py

# Run with coverage
pytest --cov=openbench

Code Quality

# Format code
ruff format .

# Lint code
ruff check .

# Type checking
mypy .

# Run all pre-commit hooks
pre-commit run --all-files

Using the CLI

# List available benchmarks
bench list

# Describe a specific benchmark
bench describe mmlu

# Run evaluation
bench eval mmlu --model groq/llama-3.1-70b --limit 10

# View previous results
bench view

Installing Dependencies

# Install core dependencies only (runs most benchmarks)
uv sync

# Install with specific benchmark dependencies
uv sync --group scicode       # For SciCode benchmark
uv sync --group jsonschemabench # For JSONSchemaBench

# Install with development tools
uv sync --dev

# Install everything
uv sync --all-groups

Publishing to PyPI

# Build the package
uv build

# Publish to PyPI (requires PyPI API token)
uv publish

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

openbench CLAUDE.md is an instructions file published in the GitHub repository groq/openbench (813 stars, last pushed 7d ago), licensed MIT. It adds 1,099 tokens to every session, about $0.0055 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
