 Slack has a ~4000 character limit per message. If the full table exceeds 25 rows, you **must** split it into multiple messages to prevent the code block formatting from breaking. Don't send the message as json.
 
+**Important — Slack message formatting:** Always send message text with **actual line breaks**, not `\n` escape characters. If you type `\n` literally in the input, the entire message will appear as one long line in Slack. Write the message across multiple lines in the input field itself
+
 **Splitting logic:**
 1. Calculate the number of parts needed: `ceil(total_rows / 25)`
 2. Each message must be a **self-contained code block** (with its own opening and closing triple backticks)
