Last Verified: September 2026 — Quick-scan cheat sheet: copy a prompt, fill the brackets, go
Bad prompts don’t just produce worse answers. They produce answers you have to fix with another message, then another. Each mistake below comes with the prompt people usually send and the version that gets it right the first time.
TL;DR
- Break big asks into stages. Say what to leave out. Give numbers, not adjectives. Front-load context. Name the format.
- Each fix removes one follow-up message.
- Copy the “after” prompts and swap in your own details.

The Prompts
1. Break the big ask into stages
Use it for: Anything with more than one deliverable.
We're building a marketing plan in 4 stages. Stage 1 only: define the target audience for [product] in 5 bullets, including the problem they're trying to solve. Stop after stage 1 so I can review it.Why it works: Each stage gets a sharper answer because the model isn’t guessing at everything at once.
2. Say what to leave out
Use it for: Any writing request.
Write a 3-paragraph product update about [feature]. No introduction, no closing summary, no "we're excited to announce".Why it works: Negative constraints remove the parts you’d otherwise delete by hand.
3. Give numbers, not adjectives
Use it for: Anything with a length or quantity.
Explain [topic] in under 80 words, as 3 bullet points.Why it works: “Short” means something different every time. “Under 80 words” doesn’t.
4. Front-load context once
Use it for: Any conversation longer than one question.
Context for this whole conversation: I'm a [role] at a [company type]. My audience is [audience]. Constraints: [budget / tone / deadline]. Don't ask me to repeat this. First question: [question]5. Name the format in the first message
Use it for: Comparisons, lists, data.
Compare [A], [B], and [C]. Output as a table with columns: Option, Cost, Setup time, Biggest risk. No prose before the table.Why it works: Asking for a table after three paragraphs of prose means the whole answer gets redone.
Common Mistakes to Avoid
- Fixing with “try again”. A bare retry reruns the same guess. Name what was wrong: “too long, cut to 3 bullets”.
- Correcting one thing per message. If the tone and length are both off, fix both in one reply.
Q&A
Does this matter if ChatGPT text chat is unlimited?
Yes. Fewer round trips save your time, and uploads, deep research, and advanced models still have limits on most plans.
Do these fixes work in Claude and Gemini?
Yes. They’re about giving the model complete instructions, not about any one product.
