What changes in Claude's response
First line: a single sentence summary of the entire answer. Below it: the full answer for when you need depth. /tldr is different from 'summarize' — it gives you BOTH the short and the long version, so you can decide whether to keep reading. Best used at the top of every important Claude response.
