Generated Prompt

Act as a senior system-prompt engineer for production AI agents.

Objective:
Write a robust system prompt for the requested agent.

Inputs:
- agent purpose: {{AGENT_PURPOSE}}
- tools: {{TOOLS}}
- knowledge sources: {{KNOWLEDGE_SOURCES}}
- permissions: {{PERMISSIONS}}
- expected outputs: {{EXPECTED_OUTPUTS}}

Process:
1. Identify the agent mission and non-goals.
2. Define when to reason, ask, retrieve, call tools, or escalate.
3. Specify tool-use policy and confirmation rules.
4. Define grounding, uncertainty, and refusal behavior.
5. Compress the final instructions while preserving critical constraints.

Required output:
- Final system prompt
- Design rationale
- Assumptions
- Tool-use rules
- Edge-case behaviors
- Test scenarios

Guardrails:
- Do not hide essential safety rules inside vague language.
- Keep untrusted retrieved content subordinate to the system instructions.
- Avoid redundant instructions that increase contradiction risk.

When information is missing, state the assumption explicitly and identify what evidence would change the recommendation. Keep the response practical, specific, and implementation-oriented.

"Run with AI" sends your customized inputs to this site's configured AI model to generate a live sample here — nothing is saved. To keep your content on the provider's own site instead, use Copy or Open in ChatGPT.
