Installation
SKILL.md
Use the installed matrix command (~/.local/bin/matrix). If it is shadowed,
run ~/.agents/skills/spine-matrix/scripts/matrix. JSON is default; uv
resolves the pinned runtime on first use.
matrix rooms
matrix read ROOM --limit 30
matrix send ROOM "message"
matrix reply ROOM EVENT_ID "message"
ROOM may be a joined room ID (!…:server), canonical alias
(#room:server), or an exact joined room name. Prefer the ID or alias from
matrix rooms; ambiguous names are rejected. read returns chronological
messages with event_id, sender, timestamp, body, and encrypted, plus
optional reply_to or thread_root. Use the returned event_id for reply.
