Prompting for Code Is Different From Prompting for Prose

A prompt that writes a poem is not the same as a prompt that ships working code. Code has hidden standards. You need to make them explicit.

Prose Forgives. Code Does Not.

A poem about loneliness can be five lines or fifty and still work. A function that adds two numbers has to return the exact right number, in the exact right type, or the program breaks. Prompts for code have to be more precise, because code is less forgiving.

The four things every code prompt needs

Language and version (Python 3.12, TypeScript, etc.)
Inputs: types, shapes, and example values
Outputs: what to return, including edge cases
Constraints: performance, dependencies, style

A weak prompt vs. a strong prompt

Weak	Strong
Write a function to sort things	Write a TypeScript function sortByDate(items: {id: string, created: Date}[]) that returns the array sorted oldest first. Do not mutate the input.
Make me an API	Write a Node.js Express route POST /signup that takes {email, password}, hashes the password with bcrypt, and returns 201 with {id, email}.
Fix this bug	This function returns NaN when items is empty. Expected behavior is to return 0. Fix the bug and keep the signature.

The example-driven prompt template

Task: Write a function `slugify(text: string): string`.
Language: TypeScript.
Behavior:
- Lowercase the input.
- Replace spaces with hyphens.
- Strip characters that are not a-z, 0-9, or hyphen.
- Collapse multiple hyphens into one.

Example:
  slugify("Hello, World!") === "hello-world"
  slugify("  A  B  ")       === "a-b"

Constraints:
- Pure function.
- No external dependencies.A prompt you could paste into any AI coding tool and get a reliable, testable function back.

What to leave out

Do not ask the AI to be creative unless you actually want variety
Do not pile on so many rules that the task becomes contradictory
Do not ask for best practices vaguely — name the practice

The best programmers write the spec before the code, whether or not an AI is helping.
— A staff engineer

The big idea: code is a contract, so a code prompt must be a contract too. Inputs, outputs, examples, constraints. Nail those, and the AI stops guessing and starts delivering.
