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. Defines the HTML subset clients render, the type-tag system, glyph rules (no rockets, no party emoji), the m.text vs m.notice choice, and when to render an HTML card to PNG instead
The exact command may vary by repository. Check the README on GitHub.
