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 rolling-scopes/rsschool-app at 446952a8ed.

    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 type definitions for improved code safety and maintainability. Specifically, it facilitates working with conditional types, mapped types, and utility types within a TypeScript project.

When to use it

  • Refactoring existing TypeScript code: When needing to improve the type safety and clarity of an older codebase.
  • Creating reusable component libraries: To define precise types for props and return values in React or other UI frameworks.
  • Building complex data structures: For projects requiring intricate object shapes with specific constraints.
  • Enforcing stricter code contracts: When ensuring that functions receive and return data of the expected type is critical.

Key capabilities

  • Conditional Types
  • Mapped Types
  • Utility Types

Example prompts

  • "Generate a mapped type that converts all properties in this interface to read-only."
  • "Create a conditional type that returns 'string' if a value is null, otherwise return its actual type."
  • “How can I use Pick and Omit utility types to extract specific fields from an object?”

Tips & gotchas

This skill requires a foundational understanding of TypeScript basics. Complex type manipulations can be difficult to debug; careful testing with example data is recommended.
