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 mcollina/skills at 856efd268a.

    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-magician skill empowers AI agents to generate, debug, and refactor TypeScript code with precision. It acts as a specialized assistant for backend developers needing rapid prototyping or complex type safety enforcement.

When to use it

  • Generating boilerplate code for new backend services in TypeScript.
  • Refactoring existing JavaScript logic into strongly typed TypeScript modules.
  • Debugging runtime errors by analyzing type mismatches and suggesting fixes.
  • Creating unit tests with proper type definitions for API endpoints.

Key capabilities

  • Advanced TypeScript syntax generation and completion.
  • Intelligent refactoring of legacy codebases to modern standards.
  • Type inference optimization and strict mode enforcement.
  • Error detection and resolution within complex backend architectures.

Example prompts

  • "Create a REST API handler for user authentication using Express and TypeScript."
  • "Refactor this JavaScript function to use strict TypeScript typing with interfaces."
  • "Debug this error: 'Type 'string' is not assignable to type 'number'" in my payment processor module.

Tips & gotchas

Ensure your development environment has the latest TypeScript compiler installed, as the skill relies on current language features. For best results, provide context about your existing project structure when requesting code generation.
