"""Generate the Automation Blueprints catalog JSON for the docs site.

Mirrors ``extract-skills.py``: imports the single-source-of-truth blueprint
definitions from ``cron/blueprint_catalog.py`` and emits a flat JSON array the
docs page renders into cards (description, schedule, copy-paste slash command,
and a ``hermes://`` "Send to App" deep-link).

Output: ``website/static/api/automation-blueprints-index.json`` (served at
``/docs/api/automation-blueprints-index.json``). Run automatically by
``website/scripts/prebuild.mjs`` before ``npm start`` / ``npm run build``.
