About this skill

What it does

This skill allows AI agents to understand and generate n8n expression syntax. It can parse complex expressions, identify potential errors, and construct new expressions based on user instructions or existing workflows. The goal is to simplify the creation of automated workflows within the n8n platform.

When to use it

  • Debugging n8n Workflows: Ask the agent to analyze a problematic expression for syntax errors or logical inconsistencies.
  • Generating Expressions from Descriptions: Describe the desired functionality (e.g., "format this date as YYYY-MM-DD") and have the agent generate the corresponding n8n expression.
  • Translating Between Expression Styles: Convert expressions written in one style to another, potentially for compatibility or readability improvements.
  • Creating Complex Conditional Logic: Generate complex conditional statements within an n8n workflow based on specific criteria.

Key capabilities

  • Expression parsing and validation
  • Generation of n8n expression syntax
  • Error identification and explanation
  • Translation between different expression styles (implied)

Example prompts

  • "Can you check this n8n expression for errors: {{ $json.someValue + 1 }}?"
  • "Generate an n8n expression to format the current date as 'YYYY-MM-DD'."
  • “I want to create a conditional in n8n that checks if a value is greater than 10, what’s the expression for that?”

Tips & gotchas

  • Requires familiarity with n8n's data handling and available functions. The agent will perform best when given context about the specific workflow or data being processed.
