Category: Engineering  ·  Sub-category: mobile  ·  Last updated:
lang:typescript
This skill should be used when working with TypeScript 4.9 through 5.7 features, using the satisfies operator, const type parameters, inferred type predicates, verbatimModuleSyntax, isolated declarations, or targeting ES2024. Trigger on: "satisfies operator", "const type parameter", "TypeScript 5.0", "TypeScript 5.5", "TypeScript 5.7", "inferred type predicate", "verbatimModuleSyntax", "es2024 target", "TypeScript 4.9 features", "using declaration", "override keyword", "TypeScript new features", "import type syntax", "isolatedDeclarations", "Promise.withResolvers", "satisfies vs as", "satisfies vs annotation".

From the source SKILL.md

These features fundamentally change how type-safe code is written. Understanding them prevents the use of less-safe older patterns.
