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 allows AI agents to leverage advanced ECMAScript features within a TypeScript environment. It enables the agent to understand and utilize modern JavaScript syntax, improving code readability and efficiency when working with TypeScript projects. Specifically, it facilitates the use of newer language constructs while maintaining type safety.

When to use it

  • Modernizing Legacy Code: Refactor older JavaScript codebases into TypeScript by leveraging ECMAScript features for cleaner transitions.
  • Complex Data Transformations: Employ advanced array methods and object manipulation techniques within a typed context.
  • Developing New Features: Build new components or modules using the latest ECMAScript syntax, ensuring type safety throughout the process.
  • Code Reviews & Refactoring: Identify opportunities to improve existing TypeScript code by applying more concise and expressive ECMAScript features.

Key capabilities

  • Understanding of modern JavaScript syntax within a TypeScript context.
  • Utilization of advanced array methods (e.g., flatMap, findLast).
  • Object manipulation using spread/rest operators.
  • Application of optional chaining (?.) and nullish coalescing (??).

Example prompts

  • "Refactor this JavaScript function into TypeScript, utilizing modern ECMAScript features for improved readability."
  • "Show me how to use flatMap in TypeScript to transform an array of objects."
  • “Can you rewrite this code using optional chaining to safely access nested properties?”

Tips & gotchas

This skill assumes a basic understanding of both JavaScript and TypeScript. While it enhances code expressiveness, ensure proper type annotations are maintained for optimal type safety.
