# Pull Request Guidelines Thank you for contributing to the project! Please make sure your pull request follows these guidelines before submission. --- ## Requirements - **AI-generated code must be reviewed.** Tips to identify AI-generated code: - Verbose or redundant JSDoc — make JSDoc synthetic and concise. - Abbreviations in variables or functions (e.g., `d` instead of `dictionary`) — avoid abbreviations. - Overly compact code — add line breaks and spacing to improve readability. - **Tests and build must pass** before requesting a review. - **Commits must follow the [Conventional Commit](https://www.conventionalcommits.org/) format.** - **The [`CONTRIBUTING.md`](./CONTRIBUTING.md)** file must be read before submitting a PR. --- ## Codebase Conventions - Prefer **arrow functions** (`() => {}`) over function declarations (`function () {}`). - Prefer **TypeScript `type`** over `interface`. Use `interface` only for **module augmentation**. - For better testing and reusability, prefer **one function per file**. - Prefer **`??`** over **`||`** syntax. - Prefer **`import type`** over `import` for type imports. - Prefer named exports over default exports. - Avoid abbreviations in variable names: - `locale` instead of `loc` - `map(dictionary => dictionary.key)` instead of `map(d => d.key)`
