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 redcoatasher/n8n-skills-redux at 016cdb4699.

    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 you to execute JavaScript code within an n8n workflow. It provides a way to dynamically manipulate data, perform complex calculations, or interact with APIs that are not directly supported by n8n's built-in nodes. The resulting output from the executed JavaScript is then available for use in subsequent workflow steps.

When to use it

  • Data Transformation: Modify and reshape data received from external sources before sending it to another application or service.
  • API Interaction: Call APIs that require custom authentication or complex request formatting not easily handled by standard nodes.
  • Complex Logic: Implement intricate business rules or calculations that are difficult to express using n8n's visual workflow editor.
  • Dynamic Content Generation: Generate content, such as email subject lines or social media posts, based on data received from previous workflow steps.

Key capabilities

  • Execute JavaScript code snippets.
  • Access and modify input data within the script.
  • Return output data to be used in subsequent workflow nodes.

Example prompts

  • "Write a Javascript function that calculates the shipping cost based on order total and destination."
  • "Use this JSON data and extract the 'product_name' field using JavaScript."
  • "Format this date string into YYYY-MM-DD format using JavaScript."

Tips & gotchas

  • Requires a basic understanding of JavaScript syntax. Errors in your code will prevent the workflow from executing correctly.
