AI agents like Claude Code and Cursor can be guided by project-specific rule files, such as CLAUDE.md or AGENTS.md, placed at the root of a repository. These files act as system prompts, enforcing coding styles, prohibiting certain practices, and ensuring consistency in code generation across a project. The article provides a detailed example for FastAPI projects, outlining rules for stack, router design, dependency injection, error handling, and testing, emphasizing that clear structural guidelines are more effective than simple prohibitions for AI agents. It also suggests best practices for rule file management, including keeping them concise, focusing on positive structures, and treating them as infrastructure-as-code within team workflows. AI
IMPACT Enables developers to enforce consistent coding standards and improve the reliability of AI-generated code within projects.
RANK_REASON Article describes how to use existing AI tools (Claude Code, Cursor) with custom configuration files, rather than a new AI release or research.
