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 wilkomarketing/antigravity-n8n-skills at 2516fdb121.

    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 provides access to and utilizes n8n expression syntax. It allows AI agents to construct complex workflows within the n8n automation platform, enabling data manipulation, conditional logic, and integration with various APIs. The skill facilitates building automated processes for tasks like data transformation, email sending, and database updates.

When to use it

  • Automating repetitive marketing tasks: Use it to dynamically generate personalized email content based on customer data pulled from a CRM.
  • Integrating different SaaS tools: Connect your e-commerce platform with your accounting software using n8n expressions for order fulfillment.
  • Building custom API integrations: Create workflows that interact with internal or external APIs requiring complex data transformations.
  • Implementing conditional logic in automations: Route leads based on their behavior and engagement level within an automated marketing funnel.

Key capabilities

  • n8n Expression Syntax Support
  • Workflow Automation
  • Data Manipulation
  • API Integration

Example prompts

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

Tips & gotchas

  • Requires familiarity with n8n and its expression language. A basic understanding of programming concepts will be helpful.
  • Complex expressions can become difficult to debug; break down complex tasks into smaller, manageable steps within your n8n workflow.
