Introduction

The agentic-ai-prompt-research repository, also known as "Claude Code System Prompts," is an independent research project dedicated to unraveling the complex prompt architectures and operational mechanisms of agentic AI coding assistants. By analyzing observable behavior, output, and community discussions, this project reconstructs the likely system prompts, agent coordination patterns, and security classifications that power sophisticated tools like Claude Code. It's an educational resource for anyone looking to understand the underlying design principles of these advanced AI systems.

How to Use This Research

This repository is not a software library to install, but rather a comprehensive documentation and analysis project. To leverage its insights, users should explore the prompts/ directory, which contains detailed markdown files for each documented pattern. Each file explains a specific aspect, from core identity prompts to specialized agents and security protocols. Researchers and developers can study these patterns to inform their own AI system designs or to gain a deeper understanding of existing ones.

Key Patterns and Examples

The project meticulously documents various patterns observed in agentic AI assistants. Here are a few examples of the architectural insights you'll find:

  • Main System Prompt: Details how the master prompt is dynamically assembled from modular sections, covering identity, safety, permissions, and tool preferences.
  • Coordinator System Prompt: Explores multi-worker orchestration with phased workflows, crucial for managing complex tasks across multiple AI agents.
  • Verification Agent: Describes an adversarial testing agent designed to validate implementations and ensure robustness.
  • Auto Mode Classifier: Unpacks the multi-stage security classification system used for autonomous tool execution, including predefined rules and user-configurable overrides.
  • Compact Service: Illustrates conversation summarization strategies vital for managing context windows in long sessions.

For a complete list and detailed explanations, refer to the Documented Patterns section in the README.
