Prompt optimization for vibe coders

· 2 min read

Quick answer

When you build an app by talking to an AI, the aim is not the shortest prompt but the clearest one. Say the goal, the screen, what must not change and how you will check it. Let Typo remove the filler, and keep the level at 3 or below for build requests.

Start with the outcome

Tell the builder who the change is for, which screen or behavior to change and what it must not break. “Make the dashboard nice” is short, but it leaves the builder guessing, and guessing costs another round.

A clearer prompt, written by you

Before: I want a better task dashboard. It needs to work on mobile and have dark mode. Do not remove existing tasks.

Clearer: Improve the task dashboard for mobile and dark mode. Keep existing tasks and data. Show a summary of the changes and test the small screen layout.

The clearer version is longer. That is fine when it prevents a second build. Typo's token language never adds requirements. A rewrite like this is something only you can do.

Five things to protect

  • Existing user data, and any database changes.
  • Which screens, components and user roles may change.
  • Mobile layout and keyboard access.
  • Sign-in, permissions and secrets.
  • What done means: build, preview and test results.

What Typo does for you

Example at level 3: Polite wordingEstimated tokens: 35 → 22 (−37%)
You typeHey there! Could you please make the signup form basically a bit nicer on mobile? Do not remove the existing fields. Thank you so much!
Sent to the AIMake the signup form basically a bit nicer on mobile. Do not remove the existing fields.

Which level

Levels 1 to 3 when the builder edits a live app. Higher levels for broad ideas in a chat or planning mode. No level removes a “do not”, a file name or a number.

Using Typo with app builders

If your builder's site is not on Typo's Auto list (Lovable, Bolt and v0 are, from Typo 0.12), choose Always while you build or press Ctrl+Alt+T on Windows to shorten a finished prompt. Ctrl+Alt+Z brings the original back.
