What is the main benefit of using this skill?

It allows AI agents to present information visually using Slack's Block Kit instead of plain text, making responses significantly easier to read and interact with for team members.

Does this skill handle markdown conversion?

Yes, the skill includes logic and reference patterns for converting standard markdown into Slack's specific mrkdwn format to ensure correct visual rendering.

Can I add interactive buttons to agent responses?

Absolutely. The architecture supports 'actions' blocks, enabling you to include buttons that users can click to trigger secondary workflows or tool calls.

Are there limits to the message size?

Yes, the skill enforces Slack's native limits: a maximum of 50 blocks per message and 3000 characters per text field to ensure delivery success.
