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 hairyf/skills at 8a84374860.

    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, unjs, provides access to a collection of JavaScript utility functions. It can be used to perform common tasks like string manipulation, array processing, and object handling within an AI agent's workflow. The specific functionality is derived from the unjs library, offering concise and reusable code snippets for various programming needs.

When to use it

  • Data Transformation: When needing to clean or reshape data received from external sources before further analysis or action.
  • String Parsing: When an AI agent requires extracting specific information from text-based inputs like emails or web pages.
  • Array Manipulation: To efficiently filter, sort, or modify lists of items retrieved from APIs or databases.
  • Object Handling: When needing to access and modify properties within complex data structures.

Key capabilities

  • String manipulation functions (e.g., trimming, splitting)
  • Array processing methods (e.g., filtering, mapping)
  • Object utility functions (e.g., deep cloning, merging)
  • Provides a comprehensive set of JavaScript utilities from the unjs library

Example prompts

  • "Use unjs to extract all email addresses from this text: [text]"
  • "Can you filter this array using unjs: [array]?"
  • “Using unjs, merge these two objects: [object1], [object2].”

Tips & gotchas

The specific functions available depend on the version of unjs being used. Refer to the unjs documentation for a complete list of capabilities and potential limitations.
