matrix-administration skillA
matrix-administration is agent-read markdown (skill) from netresearch/matrix-skill: 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 operatio.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add netresearch/matrix-skill/matrix-administration@v3.1.3mdr add netresearch/matrix-skill/matrix-administration@sha256:a98d9ba3d7d6bfe7Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
