AI Prompt Cleaner

A well-structured system prompt is the difference between an AI agent that reliably handles edge cases and one that hallucinates, makes promises it cannot keep, or fails to escalate urgent issues. This tool takes rough, informal agent instructions and outputs a structured system prompt with clear role definition, operating rules, and escalation paths.

What makes a good system prompt

Good prompts define the agent's role (what it is), goal (what it is trying to accomplish), and constraints (what it must not do). They explicitly address the most dangerous failure modes: hallucination, over-promising, handling sensitive topics, and knowing when to hand off to a human. Short, declarative rules are more reliably followed than long paragraphs of guidance.

Common mistakes in agent prompts

Vague instructions like "be helpful" without defining what helpful means in context. No escalation path for situations the agent cannot handle. Missing instructions about how to handle sensitive user data or emotional distress. Conflicting instructions (rule 3 says X but rule 7 implies not-X). This tool imposes a consistent structure that covers the most common gaps.

For production AI agents, the system prompt is just the start. You also need output filtering, input sanitization, rate limiting, logging, and human-in-the-loop review for high-stakes decisions. ruxox builds AI agents with all of these layers built in — the prompt is the starting point, not the whole system.
