How to install

Cursor 3.3+ (recommended — per-stack rules)

Copy individual rule files into your project:

# Example: add React rules to your project
cp .cursor/rules/react.mdc /your-project/.cursor/rules/react.mdc

Each .mdc file uses globs to auto-attach to relevant files — Cursor activates the right rules automatically based on what you're editing.

Cursor 2.x / legacy

Copy the relevant section from .cursorrules into your project's .cursorrules file at the project root.

What makes these different

Most .cursorrules files online are generic ("write clean code", "follow best practices"). These rules encode specific production conventions:

• React: Feature-based folder structure, TanStack Query patterns, cn() Tailwind approach, no React.FC
• Next.js: App Router conventions, Server vs Client Component boundaries, Server Action patterns
• TypeScript: noUncheckedIndexedAccess, discriminated unions, satisfies operator usage
• FastAPI: Pydantic v2 patterns, AsyncSession, proper dependency injection chains
• Go: Error wrapping with %w, interface-at-call-site rule, context-first concurrency
• Rust: thiserror vs anyhow, ownership borrow-before-clone, spawn_blocking for CPU work
• Docker: Multi-stage builds, pinned versions, non-root user pattern
• PostgreSQL: TIMESTAMPTZ, CREATE INDEX CONCURRENTLY, parameterized queries always

These rules were written from daily production use — they encode what we actually enforce in code review, not what sounds good in a blog post.
