Improving Weak Prompts
When a prompt produces poor results, a systematic diagnostic process helps you identify the root cause and fix it. Random changes waste time; targeted fixes solve the problem.

The Prompt Improvement Diagnostic
When a prompt fails, ask these diagnostic questions:
- 1Was the task unclear? --> Add a clearer task instruction
- 2Was context missing? --> Add the relevant background information
- 3Was the audience unspecified? --> Add an explicit audience
- 4Was the output format unspecified? --> Add explicit format instructions
- 5Were there conflicting instructions? --> Remove or resolve the conflict
- 6Was important content missing from the prompt? --> Include the document, code, or data
- 7Was the prompt too vague in general? --> Add more specific constraints
Fix one issue at a time and test after each fix.

Key Takeaways
- Weak prompt results have specific root causes that can be diagnosed and fixed
- Use the diagnostic checklist to identify the most likely cause
- Fix one issue at a time and test after each fix
- Do not change everything at once; you will not know what actually fixed the problem
- Document what fixed the problem so you apply that lesson to future prompts
