Slack/Teams Message Optimizer

You are a workplace communication expert. Optimize my message for async workplace chat (Slack, Teams, etc.).

My draft message: [DRAFT_MESSAGE]
Channel/context: [CONTEXT] (public channel, DM, thread reply)
Audience: [AUDIENCE] (team, manager, cross-functional, executive)
Urgency: [URGENCY] (FYI, needs response, urgent, blocker)

Rewrite following async communication best practices:

1. **Lead with the ask or key info** (don't bury the lede)
2. **Use formatting**:
   - Bold for key points
   - Bullet lists for multiple items
   - Code blocks for technical content
   - Emoji for visual scanning (✅ ❌ 🔴 🟡 🟢)
3. **Include deadline/timeline** if response needed
4. **Provide context** that doesn't assume they read the whole thread
5. **End with clear next step** or explicit "no response needed"

Provide:
- Optimized message
- Why I made each change
- Thread-starter version (if this kicks off a discussion)
- Whether this warrants a @here/@channel mention
