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 joabgonzalez/ai-agents-skills at 996910df28.

    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 provides access to JavaScript functionality within an AI agent. It allows agents to execute JavaScript code, enabling tasks like data manipulation, calculations, and interacting with APIs that require JavaScript scripting. The skill facilitates dynamic behavior and complex logic beyond standard language processing capabilities.

When to use it

  • Data Transformation: When needing to reshape or clean datasets using JavaScript's flexible string and array manipulation features.
  • API Interaction: To handle API requests requiring specific JavaScript libraries or formatting.
  • Complex Calculations: For performing intricate mathematical operations or simulations that are easier to express in JavaScript.
  • Dynamic Content Generation: When an agent needs to generate content based on complex rules or data transformations best handled with scripting.

Key capabilities

  • JavaScript code execution
  • Data manipulation and transformation
  • API interaction via scripting
  • Complex calculations

Example prompts

  • "Calculate the factorial of 10 using JavaScript."
  • "Format this date string '2023-12-25' into 'December 25, 2023' with JavaScript."
  • “Use Javascript to extract all email addresses from this text.”

Tips & gotchas

The skill requires a basic understanding of JavaScript syntax. Be mindful of potential security implications when executing arbitrary code within an AI agent environment; ensure the source and purpose of any scripts are trusted.
