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 AI agents to understand and generate valid n8n expression syntax. It enables agents to construct complex workflows within the n8n automation platform by generating expressions for data manipulation, conditional logic, and API interactions. The skill provides a structured way to leverage n8n's powerful features programmatically through an AI agent.

When to use it

  • Automated Workflow Generation: Generate entire n8n workflows or specific parts of them based on natural language requests.
  • Dynamic Data Transformation: Create expressions for transforming data between different formats in n8n, such as converting dates or manipulating strings.
  • Conditional Logic Implementation: Construct complex conditional statements within n8n to control workflow execution paths.
  • API Integration Expressions: Generate the necessary expressions to interact with external APIs and services through n8n nodes.

Key capabilities

  • Generates valid n8n expression syntax.
  • Supports data manipulation operations.
  • Enables conditional logic creation within workflows.
  • Facilitates API interaction expression generation.

Example prompts

  • "Create an n8n expression to format a date as YYYY-MM-DD."
  • "Generate an n8n expression that checks if a number is greater than 100."
  • "Write an n8n expression to extract the email address from a string."

Tips & gotchas

  • Requires familiarity with n8n's data types and operators for optimal results.
  • Complex expressions may require iterative refinement and testing within the n8n environment.
