+description: Primary skill for composing, drafting, or refining any outbound Slack content. Use this whenever the task will require using `slack_send_message`, `slack_send_message_draft`, or `slack_create_canvas`. Use `slack` to read or analyze Slack context; use this skill to produce the final outgoing message.

 ## Overview
 
-Use this skill to compose, draft, or refine Slack-ready messages and related Slack content. Apply it when the next step involves `slack_send_message`, `slack_send_message_draft`, or `slack_create_canvas`.
+Use this skill whenever the task involves producing final Slack text for a draft, send, or canvas.
+If another Slack skill is used to read or summarize source context, switch to this skill before finalizing outgoing text.
 
 ## Reference Notes
 
@@ -34,3 +35,9 @@ Read this reference **before finalizing any outgoing Slack text**:
 - Resolve **Slack user groups** before writing when the message should tag a group, and use canonical Slack mrkdwn syntax: `<!subteam^S123456>`.
 - Do not rely on bare `@name` text in outgoing Slack messages.
 - If you cannot resolve the correct user or group, **tell the user** and compose the draft or message without implying the mention will work.

+## Common Mistakes
+
+- Include `thread_ts` only when replying inside an existing thread and you have the parent message timestamp; otherwise, omit it entirely.
+- Slack draft/send collapses true blank lines. When you need a visible blank separator, use a line that contains only a zero-width space instead of an empty line.
+- After any section label, add a zero-width-space line before the next bullet or paragraph so Slack preserves the section break.

 5. Keep only candidates where the latest relevant message is from someone else, or where newer replies appeared after the user's last reply or mention.
 6. Expand only the threads or surrounding messages needed to answer accurately. Answer the question first, then add clarification or next steps when the context supports it.
