Add the skill to a bot, then ask your Chief of Staff:
“Use the Slide Deck Structure skill on this: [describe the job, or paste your notes].”
For when you do not have a set time limit (e.g., "I might have 10 minutes or 30 minutes depending on how the meeting goes"), build a tiered structure. Design the core deck for the shorter estimate. Identify a set of "expansion modules" -- 2-4 grouped slides each -- that can be inserted at specific points in the deck if time permits.
