In a Nutshell
“In a nutshell” introduces or summarizes the essential points in a very brief form. Cambridge defines it around brevity and the main points, which makes it useful as a signpost for compression rather than as a vague filler phrase.
“In a nutshell” means “very briefly” or “in a few words.” Use it when you are about to give or have just given the essential points without the full detail.

Meaning
Use the idiom when the shorter version genuinely contains the main point: “In a nutshell, the project costs more but finishes sooner.”
