@factory/eslint-plugin is an open-source ESLint plugin that enforces code organization, naming conventions, and testing patterns through custom lint rules designed to improve AI coding agent output quality.

The plugin provides pre-configured rulesets for different project types (base, recommended, frontend, and backend) covering file organization, exports, testing, logging, API routes, and React patterns. Factory recommends using this repository as inspiration to build custom lint rules tailored to your own codebase rather than directly importing the package.
