How to write great Cursor Rules

A Cursor Rules file provides a structured set of guidelines to enhance AI-generated code quality by defining patterns, best practices, and constraints tailored to specific projects or frameworks, reducing the need for manual corrections. The document outlines the process of creating and configuring a Cursor Rules file, emphasizing the importance of choosing the appropriate rule type, starting with a high-level overview, specifying essential code elements, and marking deprecated patterns. It also highlights the significance of including example patterns, verification steps, and organizing rules by categories to facilitate navigation and comprehension. Thorough testing of the rules file with diverse prompts and keeping it updated with project changes are crucial for effectiveness. The text shares insights from the experience of creating Cursor Rules for Trigger.dev tasks, noting improvements such as specifying SDK versions and addressing edge cases, which lead to more robust and consistent AI-generated code. It encourages developers to leverage such files to improve productivity and maintain consistency across codebases, offering resources for getting started with Trigger.dev and installing the rules file.
