What are the most common prompt engineering mistakes?
Typical pitfalls: dumping too much context, being vague about the goal, forgetting output format, mixing multiple tasks in one prompt, and failing to verify results. Another common issue is treating the first answer as final rather than iterating with targeted feedback. Finally, teams skip documentation, so improvements get lost. Avoid these by writing shorter, task-specific prompts, specifying structure, adding examples, and running quick checks before you trust outputs.
In practice
If you can’t state the acceptance criteria in one sentence, the prompt will likely wander.
Where to start
- [01]Add explicit output schemas for structured tasks.
- [02]Split multi-step asks into sequential prompts.
- [03]Create a simple verification checklist per task.
- [04]Version prompts and write change notes.
