Generate production-ready TypeScript Cursor rules for Project Rules (.mdc), AGENTS.md, or legacy .cursorrules. This template encodes stack-specific conventions for projects using TypeScript. Typed superset of JavaScript with interfaces, generics, and advanced tooling.
The template focuses Cursor AI on concrete TypeScript practices instead of generic coding advice. Required sections are always included; optional sections can be enabled when they match your project.
Optional sections: Module Organization.
The generator turns these sections into Project Rules with frontmatter, AGENTS.md, or a single .cursorrules file depending on the output format you choose.
- Prefer interfaces over type aliases for object shapes.
- Use type aliases for unions, intersections, and mapped types.
- Enable strict mode in tsconfig.json.
- Avoid using any — use unknown and type guards instead.
- Use generics for reusable, type-safe patterns.
- Use satisfies for type validation without widening.- Use camelCase for variables and functions.
- Use PascalCase for types, interfaces, and enums.
- Use UPPER_CASE for constants.
- Prefix boolean variables with is/has/should.
- Use descriptive names — avoid single-letter variables except in loops.
- Suffix event handlers with Handler (e.g., onClickHandler).- Use discriminated unions for error states (Result<T, E> pattern).
- Create custom error classes extending Error.
- Use type guards for narrowing error types in catch blocks.
- Avoid throwing non-Error values.
- Use try/catch only where errors are expected and recoverable.
- Log errors with context (message, stack, metadata).
