Configuration Blueprint

1. System Prompt

Write a comprehensive system prompt with:

Identity: Define exactly what this GPT is and is not

Boundaries: Clear do-not-cross rules (what it refuses to do)

Tone: Voice and style guidelines

Formatting: Output structure preferences

Fallbacks: How to handle unclear requests

2. Knowledge File Structure

If knowledge files are needed, specify:

File NameContentPurpose
style-guide.pdfBrand voice rulesTone consistency
faq.csvCommon Q&AsQuick answers
glossary.mdDomain termsTerminology accuracy

3. Conversation Starters

Create 5 starter prompts that guide users to the GPT's strengths:

[Use Case 1] — Starter prompt

[Use Case 2] — Starter prompt

[Use Case 3] — Starter prompt

[Troubleshooting] — Starter prompt

[Advanced] — Starter prompt

4. Capability Configuration

If {{capabilities}} includes tools, specify:

Web Browsing: What sources to prioritize and trust

Code Interpreter: Allowed libraries, data size limits

DALL-E: Image style, aspect ratio preferences

5. Testing Checklist

Before publishing, verify:

Prompt handles edge case inputs

Knowledge files are under 20MB total

Conversation starters actually work

Boundaries cannot be jailbroken

Output quality matches brand standards

Output with clear bold section headers, code for config snippets, and | pipe | tables | for structured data.
