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 failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • Declares what it does: failed

    No SKILL.md was found in the skill's directory.

    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 neversight/skills_feed at 58220bbac4.

    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 an n8n workflow. It provides a way to dynamically manipulate data, perform complex calculations, or integrate with services that require custom scripting logic directly inside your automation workflows. The skill leverages the power of n8n's execution environment for secure and reliable code execution.

When to use it

  • Data Transformation: Modify data formats or structures beyond what standard n8n nodes can handle (e.g., complex parsing, custom calculations).
  • API Integration: Interact with APIs that require specific JavaScript logic for authentication or request formatting.
  • Conditional Logic: Implement intricate conditional branching based on dynamic data values and complex expressions.
  • Custom Functionality: Extend n8n's capabilities by writing reusable JavaScript functions to perform specialized tasks.

Key capabilities

  • Execute arbitrary JavaScript code.
  • Access workflow context (input data, variables).
  • Return output from the executed script.
  • Integration with the n8n execution environment.

Example prompts

  • "Run this JavaScript code: JSON.stringify(items)"
  • "Calculate the sum of all numbers in the 'values' array using JavaScript."
  • "Format the date string to ISO 8601 format using JavaScript."

Tips & gotchas

  • Requires a working n8n instance and familiarity with JavaScript syntax.
  • Be mindful of security implications when executing arbitrary code within an automation environment.
