What it does
- Adds what the model needs
- A role, the task, the audience and the format you want back, so the answer fits the first time.
- Never invents facts
- Anything only you know becomes a clear [PLACEHOLDER] to fill in, instead of a guess.
- Explains every change
- A short list of what changed and why, so you get better at writing prompts yourself.
- Reads screenshots
- Attach a screenshot of a design, an error or a document, and the prompt describes it for the model.
