Common Prompt Engineering Mistakes and How to Fix Them
Fix vague goals, missing context, conflicting instructions, unsupported assumptions, and hard-to-review outputs.

Mistake: asking for everything at once
Large requests often mix research, judgment, writing, and formatting. Break the work into stages when each stage has a different success criterion.
Mistake: using vague quality words
Words such as ‘good’, ‘professional’, or ‘creative’ mean different things to different people. Define them with observable characteristics, examples, or exclusions.
Better constraint
Use a direct, calm tone. Avoid hype, unexplained jargon, and claims that are not supported by the supplied material.
Mistake: omitting source boundaries
Tell the model what material it may use and what it should do when information is missing. Ask it to label uncertainty instead of inventing facts.
Mistake: skipping evaluation
Prompt quality is measured by the usefulness of the result, not by how elaborate the prompt looks. Save a few representative inputs and review outputs against the same criteria after each change.
