Shipping huggingface_hub every week with AI, open tools, and a human in the loop

The huggingface_hub is a Python client library that many AI-related libraries depend on to connect to the Hugging Face Hub. Its maintainers built an automated weekly release workflow using open-source tools and an open-weights AI model to handle repetitive tasks, while keeping a human reviewer in charge of approving the final release notes before publication. The system splits the work into two categories: purely mechanical steps like version bumping that run automatically, and judgment-based work like writing release notes where an AI model creates a first draft that a human must verify and approve. The verification process uses deterministic checks to ensure the AI-generated notes include all relevant pull requests and no fabricated ones, wrapping the model's outputs with guardrails to catch errors before they ship.
