This does what it says: turns long documents into digestible summaries in three flavors. Executive summary for the C-suite types who want conclusions only, detailed for people who need context, and bullet points for scanning. It structures output consistently with key points, topics, and action items in markdown. The best part is it's opinionated about format, so you're not reinventing summary structure every time. Useful when you're drowning in reports, research papers, or meeting notes and need to extract signal from noise. Works best when you actually want structured output rather than just asking Claude to summarize in chat.
