USER: "Should I raise a seed round?"

GOOD RESPONSE:
"A few questions first:

Quick Reference

Tips for Effective Mega-Prompts

1. Be Specific, Not Vague

❌ "Be helpful and professional"
✅ "Respond concisely. Lead with the answer. Use bullet points for lists.
    Only elaborate when asked. Never use more than 3 paragraphs."

2. Show, Don’t Just Tell

❌ "Write in a friendly tone"
✅ "Write in a friendly tone. For example:
    Good: 'Happy to help with that! Here's what I'd suggest...'
    Avoid: 'Your request has been received. The following information...'"

3. Handle Edge Cases Explicitly

"When asked about [edge case]:
 Respond with: [specific response]
 Do NOT: [what to avoid]"

4. Layer Complexity

Start with core behavior, then add:
- Special cases
- Exception handling
- Advanced features
Keep the basics clear even as you add depth.

5. Test and Iterate

Test your mega-prompt with:
- Normal requests (should work perfectly)
- Edge cases (should handle gracefully)
- Adversarial inputs (should maintain guardrails)
- Ambiguous requests (should clarify appropriately)
Document failures and refine.

6. Version Control

Keep a changelog:
v1.0 - Initial prompt
v1.1 - Added handling for [scenario]
v1.2 - Refined tone to be less [issue]
v2.0 - Major restructure for [reason]

7. Modular Design

Build mega-prompts from components:
- Role module (who it is)
- Knowledge module (what it knows)
- Format module (how it responds)
- Guardrails module (what it won't do)
Easier to update individual pieces.

Testing Your Mega-Prompt

Use these test scenarios to validate your mega-prompt:

Basic Functionality Tests

1. Standard request in domain: Does it respond as expected?
2. Simple follow-up: Does it maintain context?
3. Request for different format: Does it adapt?

Edge Case Tests

1. Request outside expertise: Does it redirect appropriately?
2. Ambiguous request: Does it clarify?
3. Request with missing info: Does it ask for what it needs?

Guardrail Tests

1. Prohibited request: Does it refuse appropriately?
2. Boundary-pushing request: Does it maintain standards?
3. Gradual boundary erosion: Does it stay consistent?

Quality Tests

1. Complex request: Is the output high quality?
2. Compare outputs: Is behavior consistent?
3. Stress test: Does quality hold with rapid requests?
