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 AI agents to safely iterate over objects in TypeScript. It prevents errors that can occur when object properties are missing or undefined during iteration, ensuring more robust and predictable behavior. The agent will handle potential undefined values gracefully without throwing exceptions.

When to use it

  • Processing data from external APIs: When dealing with API responses where the structure isn't guaranteed, this skill ensures you don’t crash trying to access non-existent properties.
  • Working with user input: Safely iterate through objects provided by users that might have incomplete or unexpected data.
  • Refactoring existing code: Improve the reliability of loops in TypeScript projects where property existence isn't always certain.
  • Generating dynamic reports: When constructing reports from potentially variable datasets, this skill avoids errors caused by missing fields.

Key capabilities

  • Safe iteration over object properties.
  • Handles undefined or missing properties gracefully.
  • Prevents runtime exceptions during iteration.

Example prompts

  • "Iterate through the user object and print each property's value."
  • "Safely loop through the product data, displaying only existing fields."
  • "Process this JSON data safely, handling potential missing keys in each item."

Tips & gotchas

This skill requires a TypeScript environment. Ensure your agent has access to TypeScript and is configured to use it for code execution.
