sota-javascript-typescript is agent-read markdown (skill) from martinholovsky/sota-skills: State-of-the-art JavaScript and TypeScript engineering (2026) for both writing and auditing code. Covers strict TypeScript configuration and type design, language idioms and pitfalls, async patterns, Node.js backends, JS/TS-specific security (XSS, prototype pollution, supply chain, injection), frontend/React and Node performance, and testing/tooling. Use whenever building, reviewing, refactoring, or security-auditing code involving JavaScript, TypeScript, Node, npm, React, frontend code, tsconfi.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
