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 echoleesong/claude-skills-plugin at 4279343f81.

    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 allows AI agents to execute JavaScript code within an n8n workflow. It enables complex data transformations, API interactions, and custom logic that goes beyond standard AI agent capabilities. The skill leverages the power of n8n's execution environment to run these scripts securely and reliably.

When to use it

  • Complex Data Manipulation: When you need to perform intricate calculations or data reshaping not easily achieved with built-in functions.
  • Custom API Interactions: To interact with APIs that require specific JavaScript logic for authentication, request formatting, or response parsing.
  • Workflow Automation: Integrate custom code snippets into n8n workflows to automate tasks beyond standard operations.
  • Dynamic Content Generation: Generate dynamic content based on complex conditions and data sources using Javascript.

Key capabilities

  • Execute JavaScript code within an n8n workflow.
  • Access variables from the n8n workflow context within the script.
  • Return values from the JavaScript execution to be used in subsequent workflow steps.
  • Securely run scripts within the n8n environment.

Example prompts

  • "Run this Javascript code: JSON.stringify({name: 'John', age: 30}) and store the result as a variable."
  • "Execute this script to format the date in ISO format: moment(inputDate).toISOString()"
  • "Use this JavaScript code to calculate the shipping cost based on order weight and destination."

Tips & gotchas

  • Requires an existing n8n account and workflow setup. Familiarity with Javascript is necessary for effective use.
