+# TypeScript Strict Rules
+
+When working with TypeScript files, always follow these conventions:
+
+## Type Safety
+
+- Never use `any` — prefer `unknown` with type narrowing
+- Always define return types for exported functions
+- Use `readonly` for arrays and objects that shouldn't be mutated
+- Prefer `interface` over `type` for object shapes (except unions/intersections)
+
+## Imports
+
+- Use named imports, not default imports
+- Group imports: external libs, then internal modules, then relative paths
+- No circular dependencies
+
+## Naming
+
+- `camelCase` for variables and functions
+- `PascalCase` for types, interfaces, and classes
+- `SCREAMING_SNAKE_CASE` for constants
+- Prefix boolean variables with `is`, `has`, `should`, `can`
+
+## Error Handling
+
+- Never swallow errors silently (empty catch blocks)
+- Use custom error classes for domain errors
+- Always type error parameters in catch blocks
