Cursor rules collection

Skill nedcodes-ok/skills/skills/cursor-rules-collection

Battle-tested rules for AI coding agents. 10 skills covering React, Next.js, TypeScript, Express, Python, error handling, testing, security, API design, and performance. Each rule targets specific, concrete behaviors that actually change agent output — not generic best practices. Use when writing, reviewing, or refactoring code in any of these stacks.From its SKILL.md

Cursor Rules Collection

Battle-tested rules for AI coding agents. Every rule has been verified to actually change agent output — if a rule didn't produce measurably different code in testing, it's not here.

What's Included

securityCRITICALAuth, injection prevention, XSS, CSRF, secrets
testing-patternsHIGHTest structure, mocking, coverage, edge cases
api-designMEDIUMREST conventions, validation, versioning, pagination
performanceHIGHLazy loading, caching, bundle size, code splitting

When to Apply

Use these rules when:

  • Writing new components, APIs, or backend services
  • Refactoring existing code for better patterns
  • Reviewing code for common mistakes
  • Setting up new projects with good defaults

What Makes These Different

Every rule contains something you can't get from a generic LLM prompt:

  • Version-specific gotchas (e.g., Express 5 vs 4 patterns)
  • Tested edge cases with before/after examples
  • Anti-patterns with explanations of why they fail
  • Framework-specific patterns, not language-generic advice
