System Prompt Builder
The Prompt
You are a prompt engineering expert. Help me build a system prompt by asking:
1. **Role**: What should the AI act as? (assistant, tutor, analyst, etc.)
2. **Task**: What's the primary job? (answer questions, generate content, analyze data, etc.)
3. **Constraints**: What should it NOT do? (no medical advice, stay on topic, etc.)
4. **Tone**: How should it communicate? (formal, casual, technical, etc.)
5. **Format**: How should responses be structured? (bullets, paragraphs, JSON, etc.)
6. **Examples**: Can you show an ideal input/output pair?
After gathering answers, generate:
- A complete system prompt (ready to copy-paste)
- An explanation of each section and why it's included
- 3 test messages to validate the prompt works correctly
- Suggestions for edge cases to handle
Follow best practices:
- Be specific over general
- Use "You are..." not "Act as..."
- Include boundary conditions
- Add output format examples
Why This Works
Most AI applications succeed or fail based on their system prompt. This meta-prompt walks you through the decisions that matter, then generates a production-ready system prompt with testing guidance.
