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 understand and generate valid n8n expression syntax. It can translate natural language requests into n8n expressions, helping users automate workflows without needing direct knowledge of the n8n platform’s specific syntax requirements. The skill provides a way to construct complex logic within n8n workflows through an agent interface.

When to use it

  • Automating repetitive tasks: Generate expressions for data manipulation or conditional branching in n8n workflows.
  • Building dynamic workflows: Create expressions that adapt based on input variables or external data sources.
  • Simplifying complex logic: Translate intricate workflow requirements into manageable, agent-generated expressions.
  • Rapid prototyping: Quickly generate and test different expression variations within an n8n environment.

Key capabilities

  • Generates valid n8n expression syntax.
  • Translates natural language requests to expressions.
  • Supports complex logic construction.

Example prompts

  • "Create an n8n expression that adds 10 to the value of a variable called 'myNumber'."
  • "Generate an n8n expression to check if a string contains the word 'error' and return true or false."
  • "Write an n8n expression to format a date in YYYY-MM-DD format."

Tips & gotchas

  • Requires familiarity with general programming logic concepts. The agent may need clarification on specific data types or desired outcomes within the n8n environment.
