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.

About this skill

What it does

This skill enables AI agents to work with precise string types in TypeScript. It allows the agent to understand and utilize const assertions, template literal types, and mapped types for strings, ensuring type safety and improved code clarity when dealing with string data. The skill facilitates more robust and predictable behavior within TypeScript projects.

When to use it

  • Refactoring JavaScript codebases to TypeScript where precise string typing is needed.
  • Generating TypeScript code that requires specific string formats (e.g., API endpoint URLs).
  • Creating type-safe configuration files or data structures involving strings.
  • Automating the creation of string constants with associated types.

Key capabilities

  • const assertions for literal types
  • Template literal types
  • Mapped types for strings

Example prompts

  • "Generate a TypeScript function that takes an API endpoint URL as a template literal type."
  • "Convert this JavaScript code to TypeScript, ensuring all string literals have precise types using const."
  • “Create a mapped type from this array of string keys.”

Tips & gotchas

This skill requires a basic understanding of TypeScript and its type system. The agent may need additional context or examples when dealing with complex string manipulations or unfamiliar TypeScript patterns.
