This skill restructures unformatted notes and technical updates into concise Slack messages. The assistant wraps the output in a clean layout with a generation timestamp and formatted results, followed by actionable recommendations.
The prompt rules emphasize copy-paste ready text. It organizes context using bullet points and code blocks. It also advises when to move lengthy details into thread replies to keep channels tidy. Because it outputs text directly into the chat, you need to paste the formatted result into Slack yourself.
