Why this generator exists
I build custom GPTs and agents for clients weekly. The model is smart enough almost every time — what breaks is the wrapper. Wrong tone for the channel, no output-format rule, no fallback for when a request conflicts with a constraint.
This generator forces those four decisions up front: who the agent is, what it must never do, how it should sound, and exactly what shape its replies take. That's usually 80% of what separates a demo from something you can actually ship to users.
Note this is a functional agent prompt, not a brand-voice document — if you're trying to make an LLM write marketing copy that sounds like your company, start from a brand-voice prompt in the Prompt Library instead.

Quick answers
Any platform that accepts a system message or custom instructions — ChatGPT custom GPTs, Claude Projects, Gemini Gems, or a system prompt field in an agent framework like LangChain, CrewAI or n8n's AI Agent node.
It's the single most common failure mode I see — a well-designed agent that replies in the wrong shape. A support bot that returns markdown headers in a plain-text chat widget looks broken even when the reasoning is correct. Locking the format up front avoids that entirely.
Your inputs and the generated prompt are built entirely in your browser and saved to localStorage. The only thing sent to my CRM is the email you enter to unlock the full pack.
