Optimize JavaScript with Anthony Fu's AI Agent Skill

Optimize JavaScript with Anthony Fu's AI Agent Skill

This AI agent skill leverages Anthony Fu's opinionated tooling and conventions to optimize JavaScript and TypeScript projects. It is designed for developers setting up new projects, configuring ESLint/Prettier alternatives, managing monorepos, or publishing libraries, particularly where Anthony Fu's preferences are relevant.

What this skill does

• Implements Anthony Fu's conventions for code organization, focusing on single responsibility per source file.
• Encourages separating types and interfaces into distinct files and moving constants to a dedicated `constants.ts` file.
• Promotes writing isomorphic code for runtime environments and ensures clear runtime indicators are present in environment-specific code.
• Facilitates explicit return types in TypeScript and avoids complex inline types.
• Favors explicit, traceable code that avoids implicit "magic" and requires disabling auto-imports provided by frameworks such as Nuxt/Nitro in new projects.

Who it is for

This skill is suited for developers and teams using AI coding agents like Claude Code, Cursor, and Codex. It benefits those who adhere to or wish to apply Anthony Fu's JavaScript and TypeScript conventions in their development workflow.

Use cases

• Setting up new JavaScript/TypeScript projects with a consistent codebase structure based on Anthony Fu's principles.
• Optimizing library and monorepo configurations to align with opinionated coding practices.
• Improving code readability and maintenance by organizing types, interfaces, and constants into dedicated files.
• Ensuring clear runtime-specific annotations for Node, browser, and worker environments.

Technical details

This skill utilizes agent-skills, aiapplication, and antfu tools to seamlessly integrate Anthony Fu's coding conventions into JavaScript and TypeScript projects. It assists developers working within AI coding environments such as Claude Code, Cursor, and Codex, ensuring best practices are automatically applied.
