typescript-language SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
typescript-language from hoangnguyen0403/agent-skills-standard is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Apply modern TypeScript standards for type safety and maintainability. Use when working with types, interfaces, generics, enums, unions, or tsconfig settings.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TypeScript Language Patterns
## **Priority: P0 (CRITICAL)**
## Implementation Guidelines
- **Type Annotations**: Explicit params/returns. Infer locals.
- **Interfaces vs Types**: interface for APIs (supports declaration merging). type for unions, intersection types, mapped/conditional types.
- **Strict Mode**: strict: true. Null Safety: ?. and ?? — Use narrowing instead. Avoid non-null assertion (!) operator.
- **Enums**: Literal unions or `as const`. **No runtime `enum`**.
- **Generics**: Reusable, type-safe code.
- **Type Guards**: `typeof`, `instanceof`, predicates.
- **Utility Types**: `Partial`, `Pick`, `Omit`, `Record`.
- **Immutability**: `readonly` arrays/objects. Const Assertions: `as const`, `satisfies`.
- **Template Literals**: `on${Capitalize<string>}`.
- **Discriminated Unions**: Literal kind property to narrow type safely. Switch on discriminant.
- **Advanced**: Mapped, Conditional, Indexed types.
- **Access**: Default `public`. Use `private`/`protected` or `#private`.
- **Branded Types**: `string & { __brand: 'Id' }`.
## Anti-Patterns
- **NEVER use `any`**: Use `unknown` or specific interface instead.
- **No `Function`**: Use signature `() => void`.

How to install
mdr add hoangnguyen0403/agent-skills-standard/typescript-language@sha256:5dbacb158389d8c8The line at the top of this page pins the label git:20260821.b9b1ba0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
