Writing Prompt Comments So AI Builds the Right Function
Drop a clear comment above a stub and Copilot or Cursor fills in the rest — usually correctly.
7 min · Reviewed 2026
The big idea
AI coding assistants treat your comments as instructions. A specific one-line comment above a function stub gets you working code; a vague one gets you guesswork.
Some examples
You write '// returns true if email is valid, else false' and Copilot fills in the regex and return logic.
Cursor reads your '// fetch user by id, retry once on 500' comment and writes the fetch with retry baked in.
You write '// debounced search by 300ms' above an empty handler and Claude completes it with setTimeout cleanup.
Codex sees '// sort tasks by due date, nulls last' and writes the comparator without you spelling out edge cases.
Try it!
Open any project, delete a small function, leave a one-line comment of what it should do, and let Copilot or Cursor refill it.
