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 marius-townhouse/effective-typescript-skills at d754db2077.

    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 enables AI agents to understand and differentiate between various variable types in TypeScript, including number, string, boolean, any, unknown, and more. It allows the agent to correctly interpret code snippets involving these different data types and explain their behavior. The skill also covers type inference and union/intersection types for advanced usage scenarios.

When to use it

  • Code Explanation: When you need an AI agent to explain TypeScript code, particularly when variable types are involved.
  • Debugging Assistance: To help identify errors related to incorrect data type assignments or operations.
  • Learning and Education: For users learning TypeScript who want a clear explanation of different variable types and their usage.
  • Code Generation: When generating TypeScript code that requires specific variable types for correctness.

Key capabilities

  • Understanding number, string, boolean types.
  • Recognizing any and unknown types.
  • Explaining type inference.
  • Handling union and intersection types.

Example prompts

  • "Explain the difference between 'any' and 'unknown' in TypeScript."
  • "What is a union type, and how can I use it?"
  • "Can you show me an example of type inference in this code snippet: const x = 10;"

Tips & gotchas

This skill assumes basic familiarity with programming concepts. Complex scenarios involving generics or advanced type manipulation may require additional context for the AI agent to fully understand and explain.
