hermes-bsd/scripts/build_model_catalog.py

#!/usr/bin/env python3
"""Build the Hermes Model Catalog — a centralized JSON manifest of curated models.

This script reads the in-repo hardcoded curated lists (``OPENROUTER_MODELS``,
``_PROVIDER_MODELS["nous"]``) and writes them to a JSON manifest that the
Hermes CLI fetches at runtime. Publishing the catalog through the docs site
lets maintainers update model lists without shipping a Hermes release.

The runtime fetcher falls back to the same in-repo hardcoded lists if the
manifest is unreachable, so this script is a convenience for keeping the
manifest in sync — not a source of truth.

Usage::

    python scripts/build_model_catalog.py

Output: ``website/static/api/model-catalog.json``

Live URL (after ``deploy-site.yml`` runs on merge to main):
``https://hermes-agent.nousresearch.com/docs/api/model-catalog.json``
