Typescript Advanced Types

Checked
jh941213·vlatest·backend

Generates complex TypeScript code leveraging advanced types (generics, conditional types, mapped types) for robust backend solutions.

Repository

Install on your platform

This skill no longer installs under the name typescript-advanced-types. SKILL.md frontmatter is not valid YAML, so the skills CLI skips it.

We check each listing against its upstream repository with the rules the skills CLI uses, last on 2026-09-28. We don't show a command we know will fail.

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned jh941213/my-claude-code-asset at e9210e2d56.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill allows AI agents to utilize advanced TypeScript type system features. It enables the creation of complex, reusable type definitions for improved code safety and maintainability. Specifically, it facilitates tasks like defining conditional types, mapped types, and discriminated unions for more precise data modeling.

When to use it

  • Refactoring Legacy Code: When migrating JavaScript projects to TypeScript or improving existing TypeScript codebases with stricter typing.
  • Building Complex Data Structures: For applications dealing with intricate data models where type safety is paramount (e.g., e-commerce platforms, financial systems).
  • Creating Reusable Type Definitions: To establish consistent and reliable type contracts across multiple modules within a project or shared library.
  • Implementing Domain-Specific Languages (DSLs): When defining custom types to represent concepts specific to a particular problem domain.

Key capabilities

  • Conditional Types
  • Mapped Types
  • Discriminated Unions

Example prompts

  • "Create a mapped type that transforms the keys of this interface into uppercase."
  • "Define a conditional type that returns 'string' if a value is null, otherwise return its type."
  • "Generate a discriminated union for different payment methods (credit card, PayPal, bank transfer)."

Tips & gotchas

This skill requires a working knowledge of TypeScript fundamentals. Complex type definitions can be difficult to debug and may impact compilation performance in large projects.
