Common Mistakes to Avoid
The most frequent prompting errors beginners make and how to fix them instantly.
After reviewing thousands of prompts, the same mistakes come up over and over. Fixing these common errors will immediately improve your results — often dramatically.
When you bundle unrelated requests, the AI divides its attention and each answer suffers. Break complex requests into focused, sequential prompts.
Prompts that say "be detailed but keep it short" or "be creative but follow this exact template" confuse the model. When you need both, prioritize: "Keep the response under 200 words. Within that limit, include as much specific detail as possible."
AI doesn't know your situation unless you tell it. Who is this for? What's the background? What have you already tried? The more context you provide, the more relevant the response.
Don't ask AI for today's stock price, verified medical diagnoses, or to perform complex arithmetic. Know the limitations (see "Understanding Model Capabilities") and use AI where it shines.
- Did I specify what I want, not just the topic?
- Did I include enough context for the AI to give a relevant answer?
- Did I specify the format I want the output in?
- Are my instructions consistent (no contradictions)?
- Am I asking one focused question, not five bundled together?
Prompt Templates
Prompt Self-Check
Uses AI to audit and improve your prompts before sending them.
Before I send this prompt to an AI, review it for common mistakes: "[YOUR PROMPT]" Check for: 1. Vagueness — are there words that could mean different things? 2. Missing context — what would the AI need to know that I haven't said? 3. Format ambiguity — is it clear what the output should look like? 4. Contradictions — do any instructions conflict? 5. Scope — am I asking too many things at once? Rewrite the prompt with fixes applied.
Iterative Refinement Starter
Template for iterating on AI outputs without starting over.
Here's your previous response: [PASTE PREVIOUS RESPONSE] It's close, but I need these changes: 1. [SPECIFIC CHANGE 1] 2. [SPECIFIC CHANGE 2] Keep everything else the same. Only modify the parts I mentioned.

Why should you avoid asking multiple unrelated questions in one prompt?
Key Takeaways
- ✓Vagueness is the #1 cause of bad AI outputs
- ✓Ask one focused question at a time instead of bundling unrelated requests
- ✓Always specify the desired output format
- ✓Resolve contradictory instructions by setting priorities
- ✓Iterate on responses — the first output is a draft, not a final answer
