matrix-announcement skillA
matrix-announcement is agent-read markdown (skill) from netresearch/matrix-skill: 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..
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-announcement@v3.1.3mdr add netresearch/matrix-skill/matrix-announcement@sha256:b2a3741eb08a40c3Pin 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.
