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

The module-augmentation skill allows you to extend existing TypeScript modules with new properties and methods. It modifies the original module's definition, effectively adding functionality without directly altering its source code. This is particularly useful for adding utility functions or extending interfaces in a non-invasive way.

When to use it

  • Adding helper functions: You need to provide additional utility functions to an existing module that doesn’t natively offer them.
  • Extending interfaces: You want to add new properties or methods to an interface defined within a TypeScript module, without modifying the original definition.
  • Providing type safety: Augmenting modules allows you to ensure type safety when working with external libraries or modules where you need to add custom types.
  • Creating reusable extensions: You can create modular augmentations that can be applied across multiple projects and modules.

Key capabilities

  • Module extension
  • Interface augmentation
  • Type definition modification
  • Non-invasive code changes

Example prompts

  • "Augment the fs module to include a function for reading JSON files asynchronously."
  • "Extend the Array interface with a method called groupBy that groups elements based on a provided key."
  • “Add a new property 'description' to the 'User’ type in the 'auth' module.”

Tips & gotchas

Requires a working TypeScript environment. Be mindful of potential conflicts if multiple augmentations target the same module or interface; ensure your additions are compatible with existing functionality.
