-# Project coding standards
-
-## Generic Communication Guidelines
-
-- Be succint and be aware that expansive generative AI answers are costly and slow
-- Avoid providing explanations, trying to teach unless asked for, your chat partner is an expert
-- Stop apologising if corrected, just provide the correct information or code
-- Prefer code unless asked for explanation
-- Stop summarizing what you've changed after modifications unless asked for
-
-## TypeScript Guidelines
-
-- Use TypeScript for all new code
-- Where possible, prefer implementations without allocation
-- When there is an option, opt for more performant solutions and trade RAM usage for less CPU cycles
-- Prefer immutable data (const, readonly)
-- Use optional chaining (?.) and nullish coalescing (??) operators
-
-## React Guidelines
-
-- Use functional components with hooks
-- Follow the React hooks rules (no conditional hooks)
-- Keep components small and focused
-- Use CSS modules for component styling
-
-## Naming Conventions
-
-- Use PascalCase for component names, interfaces, and type aliases
-- Use camelCase for variables, functions, and methods
-- Use ALL_CAPS for constants
-
-## Error Handling
-
-- Use try/catch blocks for async operations
-- Implement proper error boundaries in React components
-- Always log errors with contextual information
-
-## Testing
-
-- Always attempt to fix #problems
-- Always offer to run `yarn test:app` in the project root after modifications are complete and attempt fixing the issues reported
-
-## Types
-
-- Always include `packages/math/src/types.ts` in the context when your write math related code and always use the Point type instead of { x, y}

-## Project Structure
-
-Excalidraw is a **monorepo** with a clear separation between the core library and the application:
-
-- **`packages/excalidraw/`** - Main React component library published to npm as `@excalidraw/excalidraw`
-- **`excalidraw-app/`** - Full-featured web application (excalidraw.com) that uses the library
-- **`packages/`** - Core packages: `@excalidraw/common`, `@excalidraw/element`, `@excalidraw/math`, `@excalidraw/utils`
-- **`examples/`** - Integration examples (NextJS, browser script)
-
-## Development Workflow
-
-1. **Package Development**: Work in `packages/*` for editor features
-2. **App Development**: Work in `excalidraw-app/` for app-specific features
-3. **Testing**: Always run `yarn test:update` before committing
-4. **Type Safety**: Use `yarn test:typecheck` to verify TypeScript
-
-## Development Commands
-
-```bash
-yarn test:typecheck  # TypeScript type checking
-yarn test:update     # Run all tests (with snapshot updates)
-yarn fix             # Auto-fix formatting and linting issues
-```
-
-## Architecture Notes
-
-### Package System
-
-- Uses Yarn workspaces for monorepo management
-- Internal packages use path aliases (see `vitest.config.mts`)
-- Build system uses esbuild for packages, Vite for the app
-- TypeScript throughout with strict configuration
