show-me — the smallest picture that answers the question

A second paragraph never fixes the first one. Pick the smallest view that makes the point, put two lines of prose beside it, stop.

The contract

1. One form, chosen on purpose. Read what the question is about, pick the matching form from the table, draw that. Several forms in one answer is the failure mode, not thoroughness.
2. Only the parts that answer the question. Keep the calls, files, props, states and boundaries the user asked about. Everything else is noise that hides the answer.
3. Prose shrinks to fit. No preamble, no "here is a diagram of". The picture leads; the words caption it.
4. Real names. Actual paths, actual function and component names, actual state values. A diagram of ServiceA → ServiceB explains nothing.
5. Say so when there is nothing to draw. A topic with no shape gets a straight answer in prose. A decorative diagram costs the reader time and buys nothing.

Pick the form from what the topic is
