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 allows you to mix JavaScript and TypeScript code within the same project or file. It enables gradual adoption of TypeScript, allowing developers to introduce type safety incrementally without rewriting entire JavaScript codebases at once. The allowJs compiler option is enabled for this purpose.

When to use it

  • Migrating a large JavaScript codebase to TypeScript gradually.
  • Working on projects with existing JavaScript dependencies that are not yet available in TypeScript.
  • Combining TypeScript modules with legacy JavaScript files.
  • When you need to quickly prototype something using JavaScript and then refactor it into TypeScript later.

Key capabilities

  • Enables the allowJs compiler option.
  • Allows mixing .js and .ts/.tsx files in a project.
  • Supports gradual TypeScript adoption.

Example prompts

  • "Can you help me integrate this JavaScript file into my TypeScript project?"
  • "How do I use allowJs to transition from JavaScript to TypeScript?"
  • “I have a legacy Javascript library, how can I use it in my Typescript project?”

Tips & gotchas

  • Ensure your TypeScript configuration (tsconfig.json) includes "allowJs": true. Without this setting, the skill will not function correctly.
  • Be mindful of potential type errors when mixing JavaScript and TypeScript code; thorough testing is recommended.
