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 wilkomarketing/antigravity-n8n-skills at 2516fdb121.

    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 you to execute JavaScript code within n8n workflows. It provides a flexible way to manipulate data, perform complex calculations, or integrate with APIs not natively supported by n8n. The skill enables custom logic and transformations directly inside your automated processes using the power of Javascript.

When to use it

  • Data Transformation: Clean, format, or restructure data from various sources before sending it to a destination.
  • API Integration: Interact with APIs that require custom authentication or request formatting not available in standard n8n nodes.
  • Complex Calculations: Perform calculations or logic beyond basic arithmetic operations offered by other nodes.
  • Custom Logic Implementation: Implement specific business rules or conditional branching within your workflows.

Key capabilities

  • Execute JavaScript code snippets
  • Access data from previous workflow steps
  • Manipulate and transform data using Javascript functions
  • Integrate with external APIs via custom HTTP requests (within the Javascript code)

Example prompts

  • "Write a function to convert this date string into ISO format."
  • "Calculate the total price including tax for these items."
  • "Extract specific information from this JSON response and return it as a new object."

Tips & gotchas

  • Requires familiarity with JavaScript programming.
  • Be mindful of potential security implications when executing custom code within your workflows.
