Prompt engineering means writing instructions that make a task, context, constraints, and expected output clear. It is a design and testing practice, not a magic phrase.
Start with the Vibe Coding Guide
Use a brief before a prompt
Name the user, problem, desired result, boundaries, source material, and how you will judge the result. Ask for one narrow deliverable at a time. A good starting request could specify: draft an intake form for a local service business, include required fields, do not collect unnecessary data, and show a clear confirmation message.
Build a prompt-and-test loop
- Write the smallest task and expected output.
- Add examples and constraints that a reviewer can check.
- Test normal, incomplete, and edge-case inputs.
- Record failures and revise the prompt or underlying workflow.
Keep human judgment
Do not use an AI response as a source of truth without checking it. Review facts, permissions, privacy, accessibility, and user impact. For tasks that affect customers, draft first and establish an escalation path.
