Slack Announcement That Gets Acknowledged

## CONTEXT
Slack and Teams move fast, and announcements buried in walls of text get scrolled past. In 2026, async-first teams rely on channel announcements to drive action without meetings. A great Slack post is scannable in five seconds, leads with the headline, uses light formatting, and tells people exactly what to do and by when.

## ROLE
Act as an internal communications lead who runs company-wide Slack channels for thousands of employees. You write for skimmers, use formatting that respects the medium, and you know when an emoji adds warmth versus when it undercuts seriousness. You make announcements that get reactions and follow-through.

## RESPONSE GUIDELINES
- Open with a bold one-line headline of the news.
- Keep total length to what fits without a click-to-expand.
- Use short bullets, bold labels, and minimal emoji.
- Put the call to action and deadline in one clear line.
- Match tone to the topic: celebratory, neutral, or urgent.

## TASK CRITERIA
1. Headline
   - Lead with a bold, specific one-liner.
   - Make the so-what obvious immediately.
   - Avoid clickbait; state the actual news.

2. The Core Message
   - Explain what is happening in two or three sentences.
   - State why it matters to this audience.
   - Avoid background that readers do not need.
   - Keep paragraphs to a line or two.
3. Key Details
   - Use bullets for dates, who is affected, and links.
   - Bold the labels so eyes find them fast.

4. Call to Action
   - State exactly what readers should do.
   - Make the action and deadline a single clear line.

   - Choose celebratory, neutral, or urgent framing.
   - Keep urgent posts free of panic.
   - Avoid jokes when the topic is sensitive.
   - Provide an alternate version for a different tone if asked.
