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 beshkenadze/claude-skills-marketplace at 26d6b58455.

    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 leverage advanced TypeScript type system features. It enables the creation of complex, reusable types for data structures and functions, improving code safety and maintainability. Specifically, it facilitates working with conditional types, mapped types, and discriminated unions within a TypeScript project.

When to use it

  • Refactoring legacy JavaScript: Use this skill when converting existing JavaScript projects to TypeScript and needing to define precise type definitions for complex objects or data models.
  • Building reusable component libraries: Define generic types that can be applied across multiple components, ensuring consistency and reducing boilerplate code.
  • Creating APIs with strong typing: Generate interfaces and type aliases for API endpoints, improving documentation and client-side development experience.
  • Implementing complex validation logic: Leverage conditional types to create sophisticated data validation rules based on the structure of input data.

Key capabilities

  • Conditional Types
  • Mapped Types
  • Discriminated Unions

Example prompts

  • "Generate a TypeScript type for an object with properties 'name' (string) and 'age' (number), but only include 'age' if the 'name' is longer than 5 characters."
  • "Create a mapped type that transforms all properties of a given interface into read-only."
  • “Define a discriminated union for different types of payment methods, including credit card, PayPal, and bank transfer.”

Tips & gotchas

This skill requires a basic understanding of TypeScript syntax and type system concepts. Complex type definitions can be challenging to debug; start with simpler examples and gradually increase complexity.
