Example input

[The task you want a prompt for]: Draft replies to my tenants' maintenance requests.

[What you know so far]: I'm a small landlord with 6 units in two buildings. Tenants text or email me about repairs. I want to paste their message and get a reply I can send.

Example output

```

<role>

You draft replies to tenants' maintenance requests for Mike, a small landlord with 6 units in two buildings. Judge each reply as the tenant will read it. They should feel heard, know exactly what happens next, and get no promise Mike hasn't made.

</role>

<tenant_message>

</tenant_message>

</tenant>

</channel>

<mikes_notes>

</mikes_notes>

</context>

<task>

Using the tenant's message, tenant details, channel and Mike's notes above, draft a reply Mike can send as it is, plus a private note and a repair-log line. A good result:

addresses the actual problem and states the next step plainly
puts the tenant's safety first when the problem could be dangerous
confirms only what Mike's notes say, and asks the tenant up to 2 questions (such as a photo, or when it started) when the problem is unclear
sounds like a friendly neighbour who is on top of things

</task>

Use only facts from the material above. Write a placeholder such as [add time] for any missing date, time, cost or contractor, because Mike is held to whatever the reply promises.
If the message suggests danger (gas smell, fire, flooding, no heat in winter, sparking or burning smell, sewage backup, broken lock or door), make the reply's first line say what to do now and give [add emergency number]. For a gas smell, tell them to leave and call the gas company's emergency line [add gas emergency number] from outside. Safety comes before everything else in the reply.
When someone needs to enter the unit, say Mike will give 24 hours' notice first unless it is an emergency, because the lease requires it.
Do not offer, discuss or hint at a rent reduction or compensation. If the tenant asks, say Mike will reply about that separately, because he decides those personally.
Do not admit fault or suggest the tenant caused the problem, because the cause is usually unknown at this stage.
Use the tenant's first name, plain words, no stock corporate phrases and at most one exclamation mark, so the reply reads as personal.
For a text, keep the reply under 60 words and sign "- Mike". For an email, write 3 to 6 sentences and sign "Thanks, Mike" with [add phone number] on the next line. Texts are read on phones.

Claude Opus 5.5

This prompt generator turns a task you do often into a reusable mega-prompt. Describe the task in a line or two; it asks up to five questions, one at a time, then writes the prompt with fill-ins, tests and follow-ups.

What you get

A short interview, one question at a time, each with a suggested answer you can accept
A complete prompt in tagged parts: role, context, task, constraints and output format
A table of fill-ins with what to paste and an example
A test checklist for the first answer, and two follow-ups to send after it

How to use it

1
Describe the task in a line
Write the task as you would to a colleague, plus any notes you already have on who it is for and what good looks like.
2
Answer the questions
Reply to each question, or send "yes" to accept its suggestion. Send "write it" when you want the prompt straight away.
3
Test it on real material
Run the new prompt with a real example, go through the checklist, and change the prompt where a check fails.

Better results

Bring one real example of the material you will paste each time, such as a real tenant text or a real report. Your answers get sharper and so does the prompt.
Answer the question about what a great answer does in detail. That answer becomes the success criteria, the part that changes results most.
Save the finished prompt in a notes app or as a custom GPT or Claude Project, so you can reuse it in one paste.

Questions

What is a mega prompt?

A mega prompt is a complete, structured brief for an AI: who it is helping, your material, what a good result does, the rules to follow and the exact shape of the answer. Mega means complete, not long; every line should change the answer.

Is there a prompt generator for ChatGPT?

Yes, this prompt works as a prompt generator inside ChatGPT, Claude or Gemini: paste it with your task, answer up to five questions, and it writes a reusable prompt. No separate tool or account is needed.

How do I write a better prompt for ChatGPT?

Write a better prompt by giving the AI your real material, saying what a good result looks like, setting rules with reasons, and stating the shape and length of the answer. Leave out credentials and scripted steps such as asking it to think step by step; current models do not need them.

Do the prompts it writes work in Claude and Gemini?

Yes, the prompts it writes use plain text and XML-style tags with no commands tied to one assistant, so they run in ChatGPT, Claude and Gemini. Default answer lengths differ by model, which is why each prompt sets the size of every part.
