WordPress Presence API

Integrate with Presence API 0.1.23 as an experimental feature plugin, not as a WordPress 7.1 core API. It supplies awareness of active users and editors using a dedicated per-site table, a 60-second TTL, Heartbeat, REST, admin surfaces, and a small public PHP API. Pin and feature-detect the plugin; its 0.1.x contract may still change.

When to use this skill

• Build who-is-online, active-editor, post-lock, or co-presence UI.
• Review wp_get_presence(), wp_set_presence(), wp_presence_post_room(), presence-ping, wp_presence_editor_state, or /wp-presence/v1 code.
• Add presence support to a custom post type.
• Decide where to store high-frequency ephemeral state.
• Audit Heartbeat load, room authorization, presence privacy, cleanup, or multisite behavior.

Establish the runtime contract first
