The Product Requirement Prompt (PRP) is a structured prompt that combines the goal and rationale parts of a traditional Product Requirement Document (PRD) and adds AI key layers (context, implementation details and strategies, verification gates), providing everything needed for an AI coding agent to build a working software vertical slice.

This is a prompt optimization server based on the Model Context Protocol (MCP) that uses AI to enhance and clean the original prompts, making them clearer, more actionable, and more effective. It supports local and cloud LLMs and provides quality assessment and retry strategies.
