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.

About this skill

What it does

This skill allows AI agents to understand and generate n8n expression syntax. It can translate natural language requests into valid n8n expressions, enabling automated workflows within the n8n platform. The skill facilitates constructing complex operations such as data manipulation, conditional logic, and API interactions directly from user prompts.

When to use it

  • Automating repetitive tasks in n8n: Generate expressions for common actions like formatting dates or extracting data from JSON responses.
  • Building dynamic workflows: Create expressions that adapt based on input data or external conditions.
  • Simplifying complex logic: Translate intricate workflow requirements into easily understandable and executable n8n expressions.
  • Rapid prototyping of n8n integrations: Quickly generate expression snippets to test new functionalities or API connections.

Key capabilities

  • Expression generation from natural language
  • Support for various n8n operators and functions
  • Ability to handle data manipulation within expressions
  • Generation of conditional logic statements

Example prompts

  • "Create an n8n expression to format a date in YYYY-MM-DD format."
  • "Generate an expression that extracts the 'email' field from this JSON: { 'name': 'John Doe', 'email': '[email protected]' }"
  • “Write an n8n expression to check if a number is greater than 10.”

Tips & gotchas

  • Requires familiarity with n8n concepts and data types for optimal results.
  • The generated expressions might need minor adjustments depending on the specific workflow context.
