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 leverage TypeScript generics in a functional programming style. It allows the agent to write more reusable and type-safe code by abstracting over types, effectively creating functions that operate on different data structures while maintaining strong typing. The skill facilitates writing concise and expressive code for tasks like data transformation and validation.

When to use it

  • Data Transformation: When needing to transform data of various types into a standardized format.
  • Type-Safe Validation: Implementing validation logic that needs to work across different object structures.
  • Component Reusability: Creating reusable UI components or utility functions that can adapt to different data models.
  • Abstracting Algorithms: Implementing generic algorithms (e.g., sorting, filtering) applicable to a wide range of types.

Key capabilities

  • Generic type parameters
  • Type inference
  • Functional programming patterns with generics
  • Abstraction over data structures

Example prompts

  • "Write a function that takes an array of numbers and returns the sum, using generics."
  • "Create a generic validator to ensure all properties in an object are strings."
  • "Implement a reusable sorting algorithm for arrays of any comparable type."

Tips & gotchas

This skill requires a basic understanding of TypeScript's type system. Incorrectly defining generic types can lead to unexpected behavior or compile-time errors, so careful consideration of the intended usage is crucial.
