Scale, weight, line height, and tracking as a coherent system. Use when building type scales, auditing typography consistency, or diagnosing why text feels off.
Use when working with TypeScript's type system including strict mode, advanced types, generics, type guards, and compiler configuration.
Apply when designing types, reviewing a function signature, or writing code in any statically-typed language. Make illegal states unrepresentable, brand semantic primitives, parse external data at boundaries, refuse to lie to the compiler, exhaust variants, derive from authoritative schemas.
Use for Luau type-system work focused on strictness modes, annotations, inference-aware API design, generics, refinements, advanced type patterns, and Roblox-aware type usage at the type level.
TypeScript 5.x development with type system, generics, utility types, and strict mode patterns. Use when writing TypeScript code or adding types to JavaScript projects.
IDA type system. Use when asked to create, modify, or apply structs, unions, enums, typedefs, or parse C declarations.
TypeScript-specific coding conventions and type system patterns. Always load this skill when writing or reviewing TypeScript code.
Advanced TypeScript type system specialist for complex generics, conditional types, template literals, type inference, performance optimization, and type-level programming. Use for intricate type system challenges, recursive types, brand types, utility type authoring, and type performance issues. Includes comprehensive coverage of 18 advanced type system error patterns.
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.
Expert Haskell engineer specializing in advanced type systems, pure functional design, and high-reliability software. Use PROACTIVELY for type-level programming, concurrency, and architecture guidance.
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.
Comprehensive TypeScript skill covering the full type system: fundamentals, generics, conditional/mapped/template literal types, utility types, strict mode, React patterns, production tsconfig, and advanced patterns from Boris Cherny (variance...
