Coding Standards

This is your cross-project foundation for naming, immutability, and code quality before you reach for framework-specific patterns. It enforces the basics: descriptive variables, spread operators instead of mutation, DRY/KISS/YAGNI principles, and consistent error handling. You'll see TypeScript examples for proper typing, React snippets for component structure and hooks, and API design conventions for REST endpoints and validation with Zod. Use it when starting projects, reviewing PRs, or setting up linting rules. It deliberately stays out of React composition details or backend architecture, those live in frontend-patterns and backend-patterns. Think of it as the shared floor that keeps your codebase readable before you layer on Next.js or Express specifics.

Coding Standards & Best Practices

Baseline coding conventions applicable across projects.

This skill is the shared floor, not the detailed framework playbook.

Use frontend-patterns for React, state, forms, rendering, and UI architecture.
Use backend-patterns or api-design for repository/service layers, endpoint design, validation, and server-specific concerns.
Use rules/common/coding-style.md when you need the shortest reusable rule layer instead of a full skill walkthrough.
