Hugging Face hosts models, datasets, Spaces, and papers. Once you connect it, the Coder can search the Hub and read one repository, including the private repositories a read token can see.
In Hugging Face, open Settings, then Access Tokens, and create a fine-grained token that can read the repositories this assistant should see. A read token is enough. It starts with hf_.
Open Integrations in StellarFirm and pick Hugging Face.
Paste the token, switch on the live option, and press Connect.
