WHAT CHANGED

- Added a clear role, task, audience, and structure.
- Replaced vague “blog post about coffee” with editable placeholders for angle, length, tone, and audience.
- Specified a required format: title, headings, introduction, body, and conclusion.
- Added quality constraints for clarity, readability, and accuracy.
- Kept the prompt focused on the original intent without adding new goals.

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.
