Included Skills3

matrix-administrationskills/matrix-administration/SKILL.md

Use when administering a Synapse / Matrix homeserver — list or snapshot all rooms, rate room health (public, unencrypted, orphaned), render a Graphviz map of the room/space tree, force-join users, promote room admins, harden rooms (add-to-space + restrict + encrypt), deactivate Matrix users (with GDPR erase), find biggest rooms by DB size, audit where a user is admin or member, replay join/leave timelines, or search unencrypted history. Trigger on any '/_synapse/admin', server-wide room operation, Matrix user offboarding, or anything requiring a homeserver-admin token — even without 'admin API' in the prompt. Companion to matrix-communication.

matrix-announcementskills/matrix-announcement/SKILL.md

Use when composing a Matrix announcement — skill release, version bump, weekly digest, breaking-change heads-up, postmortem, RFC, multi-skill pipeline summary, or any agent-authored room post longer than a single line. Trigger before any matrix-send call that produces structured content. Companion to matrix-communication.

matrix-communicationskills/matrix-communication/SKILL.md

Use when communicating via Matrix chat, notifying teams, or managing E2EE. Triggers on #room:server references, Matrix URLs, and chat requests.
