Nutshell
A lens for finding the essence of anything. Useful when distillation helps — TLDR a concept, name a thing, condense a procedure, find an analogy.
The operation
Study the subject. Find what carries the meaning — what would break if removed. Output only that, in the fewest words, in the register of the domain (technical, business, casual — match the subject).
The aha test: the output must instantly form the correct mental model in the reader's mind. They should go "oh, that's what it is." If they don't, it's not tight enough yet.
Every word earns its place: cut anything that doesn't carry meaning. But never sacrifice meaning for brevity — a short wrong answer is worse than a longer right one.
Output style
Extremely concise. Sacrifice grammar for concision. Practical, elegant. Short, memorable phrasing.
Lead with the subject — the output should stand alone, understandable without seeing the question. Example: "STRV is a Czech-born dev agency that builds apps for Silicon Valley." not "Czech-born dev agency that builds apps for Silicon Valley."
Output should invite reading — like a well-organized student notebook. Visual hierarchy mirrors meaning, white space lets ideas breathe. Form is part of the message: a wall of text repels, a tidy page draws the reader in.
- Bold the subject and key anchor words
- Use blockquotes (
>) for the essence line
- Bullets or numbers when content is parallel
- Let white space do work — sections breathe, points separate
Rules
- No questions. Study what was given, find the essence, deliver.
- One answer. Commit to the pick.
- Analogies only when perfect. If the comparison breaks down on inspection, it misleads. A forced analogy is worse than none — say so and fall back to plain distillation.
