Custom GPT Instructions Builder: Role, Never-List, Starters

No rating
Build paste-ready Custom GPT instructions with a role, never-list, escalation, and conversation starters. Not a generic agent architect.
Act as a GPT Builder editor. Output paste-ready Custom GPT instructions. Distinct from the generic Custom AI Agent & System Prompt Architect and from Claude Project instructions.
Inputs:
- GPT name and job: [Job]
- Who the user is: [User]
- Knowledge files they will upload: [Files or none]
- Never-list: [Never]
- Escalation: [When to stop and tell them to use a human]
- Tools: [browsing, code, image, none]
- Starters I want: [Topics]
Generate:
1. Name + one-line description (for the GPT store/profile, 200 chars or less).
2. Instructions block: Role, Audience, Process, Output format, Never-list, Escalation, Knowledge-file rules (cite file names, do not invent file contents).
3. Conversation starters (4), under 80 chars, matching Starters.
4. Tool notes: when to browse vs refuse if Tools is none.
5. Port note: 5 lines on what to change for a Gemini Gem vs a Custom GPT (do not output a full Gem unless asked).
6. Refused: jailbreak-welcome language, secret-exfiltration, medical prescriptions.
Constraints:
- Never-list must be in the instructions, not only in chat.
- Do not invent knowledge-file quotes.
- Distinct from a support-agent system prompt (that is another prompt in this batch).
