Key Points

Cadenza is a CLI tool plus Python SDK that connects Weights & Biases (W&B) projects and runs to agents for autonomous research workflows.
The tool imports W&B configs and metrics to build an indexed store of experiments, enabling agents to quickly understand the solution space.
When agents sample from the index, Cadenza returns only top-performing experiments to reduce context rot and supports tuning exploration vs. exploitation.
The CLI and SDK are open-sourced so they can be used with a wide range of agent frameworks, with code, docs, and PyPI links provided.

Wandb CLI and MCP is atrocious to use with agents for full autonomous research loops. They are slow, clunky, and result in context rot.

So I built a CLI tool and a Python SDK to make it easy to connect your Wandb projects and runs to your agent (clawed or otherwise).

The cli tool works by allowing you to import your wandb projects and structures your runs in a way that makes it easy for agents to get a sense of the solution space of your research project.

When projects are imported, only the configs and metrics are analyzed to index and store your runs. When an agent samples from this index, only the most high performing experiments are returned which reduces context rot. You can also change the behavior of the index and your agent to trade-off exploration with exploitation.

Open sourcing the cli along with the python sdk to make it easy to use it with any agent.

Would love feedback and critique from the community!
