The AI Drabble Challenge – Constrained Prompting

Welcome to This Week’s AI Drabble Challenge

Welcome back to our weekly playground for curious humans and equally curious machines. Every Friday I share a new prompt, and together we explore what happens when we let AI join in the storytelling.

A Drabble is simply a story told in 100 words exactly, short enough to be playful, long enough to surprise us. You’re welcome to use any AI tool you like: ChatGPT, Claude, Gemini, Grok, NotebookLM… whatever you’re comfortable with. How you collaborate is up to you. Maybe the AI drafts the first version, or writes the whole thing, maybe you co-write, or maybe you use it to spark ideas. What matters is the process, and sharing it.

There’s no pressure, no “right way,” and definitely no grading. The goal is curiosity, collaboration, and seeing what strange or wonderful things the machines produce when we give them a nudge.

This Week’s Prompt – Using Constraints

Constraints force a story away from the obvious and into more interesting territory, without them, AI generation tends toward the familiar and the predictable.

They shift the creative problem from “what happens next?” to “how do I say this within these rules?”, which is a far more generative question.

Using constraints within your prompt pushes back against the content, and that friction is where original work gets made. 

So, today’s challenge is to write a Drabble which must adhere to these two constraints:

• The opening sentence and the closing sentence must be the same.
• The story must be in the for of a letter of complaint

Feel free to interpret the prompt literally, loosely, mischievously, or in a way that makes your AI scratch its synthetic head. If it surprises you, it counts.

Example Drabble

I used Claude and the prompt was – “Write a 100-word formal letter of complaint to an unnamed authority. The writer is reporting something that should be impossible. The opening sentence and the closing sentence must be identical, but by the time the reader reaches it again, its meaning should have completely changed.“

Further to My Previous Correspondence – Urgent

I have tried to be reasonable about this.

When he first returned I contacted your office immediately, as instructed. I completed the forms. I provided the documentation. I waited. No one came. I continued to wait, and to live alongside him in the way one must, and I said nothing further to anyone.

That period is now over. I feel you have left me with little choice.

He’s still in the chair. I am standing in the kitchen. There is something in my hand that your office should probably be aware of.

I have tried to be reasonable about this.

How to Take Part

Joining in is wonderfully simple:

1. Choose any AI tool you like.
2. Ask it to write a 100-word Drabble using this week’s prompt.
3. Edit it if you want… or don’t. Imperfect is perfect.
4. Post your Drabble in the comments or publish it on your own blog and send a pingback.

If you’d like to share:

• which AI you used
• the prompt you gave it
• or a bit about your process

…that’s always appreciated and often helpful to others.

Community & Highlights

Each week I read every entry and spotlight a few that stood out, for cleverness, unexpected emotion, inventive prompting, or pure joyful weirdness. This isn’t a competition. It’s a conversation between humans, machines, and the imagination that connects us.

A Closing Thought

AI can generate the words, but only you bring the spark. So… how will you and your AI partner interpret the prompt this week?
