+## Builder feed generation

+Zero Tab publishes AI Builder JSON feeds from this repository's `feeds` branch.
+
+```bash
+npm run generate:builder-feeds
+```
+
+Sources live in [`builder-feeds/sources.json`](builder-feeds/sources.json). GitHub Actions runs [`.github/workflows/generate-builder-feeds.yml`](.github/workflows/generate-builder-feeds.yml) daily and on `workflow_dispatch`, then commits `feed-x.json`, `feed-blogs.json`, and `feed-podcasts.json` to the `feeds` branch root. The extension reads those files from `raw.githubusercontent.com`.
