Usage

Requirements

We manage environments with uv. Install uv once, then run uv sync (or uv pip install -r ...) inside the project of interest to create its virtual environment from the checked-in uv.lock.

Running Evals

Each eval directory documents how to reproduce runs, configure models, and interpret results. Start with the suite README.md, then consult any scripts under scripts/ or runtime_*/ directories for orchestration details. When in doubt:

1. cd into the eval directory.
2. uv sync to install dependencies.
3. Follow the local instructions in the README.md.

Each eval directory is its own isolated project with a README.md, pyproject.toml and uv.lock.

Development Workflow

• Create or activate the environment for the project you are working on with uv. Example for PaperBench:
  • cd project/paperbench
  • uv sync
  • uv run pytest
• Code style and linting use Ruff (with autofix profiles in pyproject.toml and project/common/tooling/ruff_autofix_minimal.toml) and Black. Run uv run ruff check --fix or use the provided Poe/make tasks where available.
• Shared utilities live under project/common; changes there may affect multiple evals. Bump the relevant editable dependencies if you create new shared subpackages.
