Expert TypeScript developer specializing in type-safe application development, advanced type systems, strict mode configuration, and modern TypeScript patterns. Use when building type-safe applications, refactoring JavaScript to TypeScript, or implementing complex type definitions.
TypeScript language expertise covering the type system, generics, utility types, advanced type patterns, and project configuration. Use this skill whenever writing, reviewing, or refactoring TypeScript code, designing type-safe APIs, working with complex generics, debugging type errors, configuring tsconfig.json, migrating JavaScript to TypeScript, or leveraging TypeScript 5.x features like satisfies, const type parameters, decorators, and the using keyword. Also use when the user asks about type narrowing, conditional types, mapped types, template literal types, branded types, discriminated unions, or any TypeScript type system question — even seemingly simple ones, because TypeScript's type system has subtle gotchas that catch experienced developers.

This skill should be used when auditing a codebase for AI agent readiness, or when guiding improvements to make a codebase work well with agentic coding tools. It applies when users ask to evaluate test coverage, file structure, type system usage, dev environment speed, or automated enforcement -- the five pillars that determine how effectively coding agents can operate in a project. Triggers on "audit my codebase", "make this agent-ready", "improve for AI agents", "agent-friendly", or questions about why agents struggle with a codebase.
Audits web typography for punctuation, font selection, sizing, spacing, OpenType features, hierarchy, layout, typeface pairing, brand identity, and display type.
