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.
