Use when communicating via Matrix chat, notifying teams, or managing E2EE. Triggers on #room:server references, Matrix URLs, and chat requests.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Matrix Communication Send, read and download media in Matrix rooms. **Always use `*-e2ee.py`.** **More than a single line? Load `matrix-announcement` first**, edits included. "Just a short status note" is not an exemption; one such note shipped naming three repos with zero links. > ## ⛔ NEVER reuse a running client's access token > > Not from Element, FluffyChat or a browser session. Not "just to test". > > E2EE state is per `device_id`, in each client's local store, so **the victim is > the client you use** — it shows `[Unable to decrypt]` for its own messages until > logged out and back in. Nothing fails at the moment you paste. > > `matrix-e2ee-setup.py` mints a device of its own. No password → no E2EE, and > that is the answer. ## Who governs the agent …

How to install
mdr add netresearch/matrix-skill/matrix-communication@sha256:180ffe367b015b2bThe line at the top of this page pins the label v4.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
