Who uses it, and for what
Build one solid follow-up prompt and reuse it for every prospect by changing the context.
Turn your reply guidelines into a prompt your AI assistant follows the same way every time.
Generate the system prompt for an AI Agent or Claude node, with a strict output format your next node can parse.
How this tool works
Separates the parts of a good prompt
Role, task, context, audience, rules, examples and format each get their own section, which is what makes results consistent.
Uses the style each model reads best
Claude follows XML tags well; ChatGPT and Gemini read Markdown headings well. Pick the style and the structure adapts.
Adds a safe fallback
Every prompt ends by asking the model to say what is missing instead of guessing, which cuts invented answers.
Frequently asked questions
Do XML tags really help with Claude?
Yes. Anthropic recommends XML tags to separate instructions, context and examples; it makes long prompts easier for the model to follow.
Should I always add an example?
When format or tone matters, one good example usually improves consistency more than several extra rules.
Can I use this prompt in n8n?
Yes. Paste it as the system message of an AI Agent, OpenAI or Anthropic node, and put the variable parts in expressions.
