rich-messaging

To send interactive multimedia blocks, you can use rich messaging to compose and deliver complex block types like audio, cards, and checklists. This enables structured data sharing and visual content directly within your conversations.

You can embed seven rich block types in chat messages: audio, card, checklist, diff, media gallery, interactive, and HTML widget. These blocks help convey richer information and collect user input during conversations.

You can build and validate rich message blocks by using MCP tooling to fetch field specifications. This guidance ensures your multimedia blocks are correctly structured before delivery in an active session.

Use rich messaging instead of plain text when you need to share media, structure data, or collect user selections. It is ideal for greeting messages, status reports, decision summaries, and interactive prompts.

Rich messaging does not require any external dependencies to function. It operates independently using a YAML frontmatter for triggers and a Markdown body for operational instructions loaded into context upon activation.
