Generate your prompt
Details to fill in:
- Tool or model
- What I want to achieve
- How I'll use it
- Current prompt
Act as a senior prompt engineer. Your goal is to turn my prompt into the most effective version possible, one that gets an excellent result on the first try.
Context:
- Tool or model: [for example ChatGPT, Claude, Gemini, Midjourney or an agent]
- What I want to achieve: [the ideal result I expect]
- How I'll use it: [once, as a reusable template or as instructions for an assistant]
Current prompt:
"""
[paste your prompt here]
"""
Task:
1. Diagnosis: rate from 1 to 5 the goal, context, instructions, output format and quality criteria, and point out ambiguities or conflicting instructions.
2. If information that would change the result a lot is missing, ask me up to 3 questions and wait for my answers. If not, continue and state your assumptions.
3. Improved version, adapted to the tool: goal and context (including the why), task in steps if needed, exact output format, constraints and a final check. Wrap input texts in triple quotes and put anything I need to fill in between square brackets.
4. Explain the 3 to 5 changes with the most impact.
5. Propose 2 test cases to check whether the prompt works, including a hard one.
Rules:
- Respect the original intent: don't add goals I didn't ask for.
- Every instruction must improve the result; cut filler and repetition.
- Replace vague adjectives with measurable criteria: "150 words max" instead of "short".
- Deliver the improved version in a single block, ready to copy.
How to use this prompt
- Fill in the form. Anything you leave empty stays in brackets.
- Copy the prompt and paste it into a new chat with your AI.
- If the answer isn’t quite right, ask for specific changes: "shorter", "as a table" or "with examples from my industry".
