cursor-rules-java vs ironcurtain

cursor-rules-java: This project offers a collection of AI system prompts designed for Java Enterprise development, aiming to enhance software engineers' daily programming and pipeline workflows. These prompts cover various aspects such as build systems, design, coding, testing, refactoring, and documentation, supporting both interactive and non-interactive behaviors.; ironcurtain: IronCurtain provides a secure runtime for autonomous AI agents, enforcing security policies derived from human-readable constitutions to prevent issues like prompt injection. It ensures agents operate within defined boundaries through mechanisms like V8 isolates and a policy engine that mediates all tool calls.

Features

cursor-rules-java logocursor-rules-java
01Comprehensive collection of AI system prompts for Java Enterprise development.
02Assists with various development phases: coding, testing, refactoring, and documentation.
03Supports interactive and non-interactive prompt behaviors.
04Provides specialized prompt behaviors like consultative interaction and progressive learning.
05Ensures quality and safety through 'The Three-Node Quality Framework'.
ironcurtain logoironcurtain
01Constitution-driven Security Policy: Define security intent in plain English, which is then compiled into deterministic and enforceable rules.
02Semantic Interposition & Runtime Enforcement: All agent interactions and tool calls are routed through a policy engine that allows, denies, or escalates based on policy.
03Untrusted Agent Model: Assumes the LLM may be compromised (e.g., by prompt injection or drift), enforcing security at the boundary regardless of the model's behavior.
04Multi-mode Operation: Supports both an internal LLM agent running in a V8 sandbox (Code Mode) and external agents running in Docker containers (Docker Agent Mode).
05Built-in Capabilities: Ships with pre-configured MCP servers for filesystem, Git, web fetching, and GitHub operations, all governed by policy.
