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 profsynapse/pact-plugin at 0cd9e88baa.

    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 integrate with services that require custom scripting logic directly inside your automation workflows. The skill executes the provided Javascript code and returns its result as output.

When to use it

  • Data Transformation: Modify data formats or values within an n8n workflow that requires more than simple built-in operations.
  • Custom Logic: Implement complex business rules or calculations not available through standard n8n nodes.
  • API Integration: Interact with APIs requiring custom request payloads or response handling via JavaScript code.
  • Dynamic Workflow Control: Use the output of Javascript execution to conditionally branch your workflow based on calculated results.

Key capabilities

  • Execute JavaScript code snippets.
  • Return the result of the executed code as an output variable.

Example prompts

  • "Calculate the square root of 144 and store it in a variable."
  • "Format this date string '2023-10-27' into 'October 27, 2023'."
  • "Create a JSON object with these properties: name = 'John', age = 30."

Tips & gotchas

  • Requires familiarity with JavaScript syntax and n8n workflow concepts.
  • The skill’s execution environment has limited access to external resources; be mindful of dependencies.
