Interactive IDE Rule Builder & Customizer

# Cursor AI System Rules & Architectural Guardrails # Generated via ideSkill.com Customizer # Target Environment: Cursor # Config File: .cursorrules ## Core Directives ### Strict Server/Client Boundaries - Always default to React Server Components (RSC) unless interactivity (useState, useEffect) is strictly required. - Never import server-only utilities (database clients, admin keys, env secrets) into client components. - Pass serializable data only across Server/Client component boundaries. ### Strict Runtime Zod Validation - Validate 100% of incoming API route handler payloads using explicit Zod schemas. - Never use "any" type or unvalidated casts (`as Type`). Prefer type narrowing and Zod inference. - Return standard 422 JSON errors with flattened issues when Zod parsing fails. ### Design System Semantic Tokens - Use designated Tailwind semantic color tokens (bg-surface, text-primary, border-border-line) instead of arbitrary hex colors. - Maintain dark-mode default contrast ratios conforming to WCAG AA. ### Red-Green-Refactor TDD Protocol - Follow strict Test-Driven Development (TDD): write unit tests (failing) before writing implementation. - Maintain minimum 90% branch coverage on newly created utility functions and endpoints. - Follow Arrange-Act-Assert (AAA) pattern explicitly in all test files. ### ContextZen Memory Architecture - Adhere strictly to ContextZen memory files: read context/project-overview.md, architecture.md, and code-standards.md before writing code. - Keep context/progress-tracker.md synchronized after each completed milestone. ## Verification Protocol - Execute all automated unit tests and type-checks before final task completion. - Ensure no code regressions or unhandled edge cases are introduced.
