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 martinholovsky/claude-skills-generator at 1086ef2567.

    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

The TypeScript Expert skill enables AI agents to generate, debug, and refactor robust backend code with strict type safety. It leverages deep knowledge of the TypeScript language ecosystem to produce production-ready solutions that minimize runtime errors.

When to use it

  • Building new backend services where compile-time type checking is required to catch errors early.
  • Refactoring existing JavaScript or loose TypeScript codebases to improve maintainability and scalability.
  • Generating complex utility functions, interfaces, and data models for API integrations.
  • Debugging intricate type inference issues or resolving conflicts between different library versions.

Key capabilities

  • Generates fully typed classes, interfaces, and generic types.
  • Implements strict null checks and union types to prevent runtime crashes.
  • Refactors legacy code into modern TypeScript patterns with improved type safety.
  • Creates comprehensive unit tests with mocked dependencies for backend logic.

Example prompts

  • "Create a REST API controller in TypeScript that handles user authentication using JWT tokens."
  • "Refactor this JavaScript function to use strict TypeScript typing and add error handling for edge cases."
  • "Generate a type-safe data validation schema for a complex order object using Zod or similar libraries."

Tips & gotchas

Ensure your AI agent has access to the specific npm packages you are using, as it may need to infer types from external dependencies. For large legacy codebases, break refactoring tasks into smaller chunks to maintain context and accuracy.
