   Please extract all actionable items from the transcript and format them as a markdown list. Each item should:
   1. Be clear and specific
   2. Start with a verb
   3. Be self-contained (understandable without context)
   4. Include any relevant deadlines or priorities if mentioned

-  # Action Items
+  Rules:
+  - One action item per line
+  - No sub-tasks
+  - No priorities
+  - Never use the "+" symbol

   - [ ] First action item
   - [ ] Second action item
   - [ ] Third action item
