**block/ai-rules** is an open-source repository maintained by Block (the company behind Square, Cash App, and other products) that provides a centralized collection of AI coding rules and configuration files for use with AI-powered development assistants. It enables teams and individuals to define, share, and enforce consistent AI behavior guidelines across projects and tools. The repository serves as a reference and starting point for configuring AI coding assistants with project-specific or organization-wide rules.

- **AI coding rules library**: Provides ready-to-use rule files that configure how AI coding assistants behave within your codebase.
- **Configuration management**: Centralizes AI assistant configuration so teams can maintain consistent standards across repositories and developers.
- **Open-source and community-driven**: Freely available under an open-source license, allowing contributions and customization for any team's needs.
- **Multi-tool compatibility**: Rules are designed to work with popular AI coding assistants and can be adapted for various tools and workflows.
- **Easy adoption**: Clone or fork the repository, copy the relevant rule files into your project, and configure your AI assistant to reference them.
- **Extensible structure**: Organized to allow teams to add, modify, or remove rules as their coding standards and AI tooling evolve.
