Devin.cursorrules
Devin.cursorrules is a configuration framework that transforms Cursor and Windsurf IDEs into autonomous coding agents capable of executing multi-step development workflows without manual step-by-step prompting. It provides a structured set of rule files and configuration templates that extend native IDE agent functionality with automated planning and extended tool capabilities.
The project bootstraps an agentic coding environment through a cookiecutter template or direct file copy, injecting plain-text configuration files into the project root that define agent behavior and tool integrations. These rule files are interpreted at startup by a static evaluation engine, enabling prompt-chained task decomposition that breaks complex development workflows into sequential sub-tasks for autonomous execution.
The framework orchestrates multi-step development tasks such as data gathering, prototyping, and cross-referencing external resources, turning a standard AI coder into a self-directed developer agent. It integrates with Cursor and Windsurf editor APIs to extend their native agent functionality with custom rules and capabilities, all managed through file-based configuration rather than runtime compilation or dynamic loading.
