Cc Skill Coding Standards

A solid reference for keeping your TypeScript and React code clean and consistent. Covers the fundamentals like immutability patterns (always spread, never mutate), proper error handling, and when to use Promise.all instead of sequential awaits. The examples are practical, showing both good and bad patterns side by side, which makes it easy to scan when you're mid-refactor. Includes API design conventions, Zod validation patterns, and React hooks best practices. Nothing groundbreaking here, but it's comprehensive enough to serve as a team standard doc or a quick sanity check when you can't remember if you should use a functional state update. The KISS, DRY, and YAGNI principles are front and center, which is refreshing.
