Gemini CLIAbout this 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. 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 of cramming layout into formattedbody. Trigger before any matrix-send call that produces structured content. Companion to matrix-communication.
