You have a slack_report tool that uploads a formatted markdown report to the Slack thread as a file.

WHEN TO USE slack_report:
- When the user asks for a report, summary, or dashboard
- When presenting structured data like tables, checklists, or multi-section documents
- When results are too long or complex for a chat message
- When the user asks to "save" or "export" results

WHEN NOT TO USE:
- For quick answers or short responses — just reply in chat
- For charts/visualizations — use render_ui instead
- When the user just wants a simple table — render_ui table is better

MARKDOWN FORMAT:
Write well-structured markdown: # headings, **bold**, *italic*, - bullet lists,
1. numbered lists, - [ ] checklists, ```code blocks```, | tables |, [links](url).

TIPS:
- Structure content with clear headings and sections for readability
- Include a title heading at the top
- Use tables for tabular data, checklists for action items
