About rulesync
dyoshikawa/rulesync
A Utility CLI for AI Coding Agents
Automatically synchronizes AI agent rules across 25+ development tools (Claude Code, Cursor, Copilot, Gemini CLI, etc.) from a unified configuration format, supporting rules, MCP servers, commands, subagents, and skills. Enables bidirectional import/export to integrate existing tool configurations and selective generation per-target with both project and global scope modes. Built as a Node.js CLI with comprehensive documentation and official skill repositories for extended functionality.
About agent-rules
lirantal/agent-rules
Rules and instructions for agentic coding tools like Cursor, Claude CLI, Gemini CLI, Qodo, Cline and more
Provides curated rule sets for secure coding, vulnerability detection, and testing that scaffold directly into agent config files (`.vscode/mcp.json`, `.github/prompts/`, etc.). Offers both interactive CLI and flag-based generation to inject MCP server configurations and custom command templates tailored to each tool's native format. Built on topic-based rule categories sourced from security and testing best practices, with non-destructive merging for existing configurations.
