7 prompt mistakes that waste your time (and the fixes)

Updated:

Most disappointing AI answers trace back to a handful of repeat mistakes. Each one has a fix, and the fix is usually a line or two.

1. Vague words

“Make it pop.” “Keep it professional.” “Improve this.” These words mean something different to everyone, and the AI has no way to know what they mean to you.

Fix: replace the adjective with something you could check.

Instead of Try
modern, clean lots of white space, one typeface, no stock photos
professional suitable for a bank loan officer, no slang
improve this cut it to 100 words and end with one clear ask
simple, quick five steps, no software to install

2. Zero context

“Give me ideas for my business” without saying what the business is. It’s the most common mistake and the most costly. Three facts (what you do, for whom, what you’ve tried) change everything. See context in prompts.

3. Everything in one message

“Write my business plan, design my logo, build my site and plan a month of posts.” You’ll get a shallow version of each.

Fix: chain it. Plan first; once the plan is solid, the copy; then the site. Each step builds on the best of the previous one.

4. No format

If you don’t specify, the AI chooses. Sometimes it guesses right. Often you get five paragraphs when you wanted a table.

Fix: one line does it. “Answer with a three-column table: option, cost, time.”

5. Only saying what you don’t want

“Don’t be formal, don’t use emojis, don’t repeat yourself.” Now the AI knows what to avoid but not what to aim for.

Fix: describe the target. “Casual, like texting a coworker. Short sentences.” If you must ban something, add why.

6. “Fix it” with no details

Classic with code, but it happens with writing too: “This doesn’t work, fix it.”

Fix: give three facts. What you expected, what happened instead, and the exact error message if there is one. For code, add how to reproduce it. There’s a template in Claude Code prompts.

7. Settling for the first answer

A prompt is the start of a conversation. If the answer is close, say exactly what to change: “Version 2 works. Make it shorter and drop the last line.”

Bonus fix: when a prompt gets you a great result, save it. Next time you start from something that already works.

The shortcut

Almost every mistake here is a missing layer: context, format, success criteria. The coach flags vague words in your goal and walks you through each layer so none slip through.
