Get coached on writing better prompts

Reviews a prompt you wrote, explains what is missing, and teaches you the habit so your next prompt is better on its own.

Prompt, 2 blanks to fill
Coach me on prompt writing.

What I want to achieve: {{GOAL}}

My prompt:
"""
{{MY_PROMPT}}
"""

1. Predict what kind of answer my prompt would probably get, and why.
2. List what is missing or ambiguous: context, audience, format, constraints, examples, success criteria.
3. Rewrite the prompt to fix those issues. Keep it as short as it can be while still clear.
4. Explain the 2 changes that matter most, as habits I can reuse.

Do not add requirements I did not ask for. If my prompt is already good, say so and suggest only small changes.

Example output

Missing: who the output is for, and the format you want. Ambiguous: "make it better" (better how? shorter, clearer, more formal?) Improved version: [rewritten prompt] Habit to keep: always say who will read the result.

How to use

Paste a prompt that gave you a disappointing answer. Compare the results of the old and new prompt side by side to see the difference.

Why it works

Predicting the answer first shows you why a prompt fails, not just that it does. Turning fixes into habits is what makes you better at prompt engineering, rather than dependent on a rewrite every time.
