ATmosphere
==========

[](#atmosphere)

This is the **ATmosphere** plugin repo.

Publish your WordPress posts to the [AT Protocol](https://atproto.com/) network — cross-post to [Bluesky](https://bsky.social/), register your articles as [standard.site](https://standard.site/) documents on your PDS, use your domain as your Bluesky handle, and mirror replies and reposts back into WordPress as native comments.

Protocol Support
----------------

[](#protocol-support)

ATmosphere implements the AT Protocol natively — no third-party proxy or intermediary service. Authentication uses OAuth 2.1 with PKCE and DPoP. Records are written to your PDS via `com.atproto.repo.applyWrites`.

Currently supported record types:

- `app.bsky.feed.post` — Bluesky posts and reply threads.
- `site.standard.publication` — your site as a publication record.
- `site.standard.document` — one document record per WordPress post.

See [`docs/content-formats.md`](docs/content-formats.md) for more on the content union used by `site.standard.document`.

- **Keep issues focused.** Use the issue tracker for specific bugs or concrete proposals. Tangential ideas are best as GitHub Discussions.
- **Stay within scope.** Open issues should relate directly to the plugin.
