Jetpack abilities, governed through the Bridge

What has to be true first

Jetpack must be installed and active on WordPress 6.9 or later, and a site-side filter must turn on jetpack_wp_abilities_enabled before any of these abilities register at all. Reading module lists and monitor status checks the jetpack_admin_page capability, changing module status also checks jetpack_manage_modules and jetpack_activate_modules, and the sitemap, shortlink, and related-posts abilities check edit_posts or manage_options.

• Nothing registers unless something on the site adds add_filter('jetpack_wp_abilities_enabled', '__return_true'); the filter ships defaulting to false and Jetpack itself never flips it.
• Once that filter is on, the Sitemaps, Shortlinks, Related Posts, and Monitor abilities still register, but each returns an error at call time unless that module is active (Monitor also requires a connected Jetpack account).
• Several ability categories easymcp lists (Connection, Backup, Stats, Forms, Newsletter) were not found registering abilities anywhere in this free zip and are unverified.

A note on the count below

Only 5 of the 10 categories easymcp lists (Modules, Sitemaps, Monitor, Related Posts, Shortlinks) were found registering abilities in this free zip; Connection, Backup, Stats, Forms, and Newsletter abilities were not found in the evidence and may require an active Jetpack connection, a paid plan, or ship in a part of the plugin the evidence pass did not capture.
