Prompt Composer: a sneak walk-through

An early two-minute screen recording of the Prompt Composer — building a structured prompt from blank frame to finished, copyable output.

Here's an early look at the Prompt Composer — about two minutes, start to finish, building a prompt the way I actually use it. It's a sneak peek: rough edges and all, but it shows the loop.

Prompt Composer — a two-minute walk-through.

What you're watching, in short:

  • Start from a frame, not a blank box. Role, Goal, Context, Bounds, Success criteria — the boring structure that makes the model behave.
  • See exactly what gets sent. A live preview of the assembled prompt, so there's no guessing what the model actually receives.
  • Leave with something reusable. Copy the finished prompt out as a clean artifact instead of a throwaway chat message.

This is the idea I keep coming back to: a prompt is worth composing, not improvising. If you want the longer version of why, that's over here. If you just want to try it, it's at prompt.phbeks.com.
