About this skill

What it does

This skill allows AI agents to interact with and execute code within an n8n workflow. It enables complex automation tasks by leveraging n8n's powerful workflow engine, including running JavaScript expressions and executing custom code snippets directly from prompts. The skill facilitates data manipulation, API integrations, and conditional logic within automated processes.

When to use it

  • Complex Data Transformations: When you need to perform intricate calculations or transformations on data that go beyond simple operations.
  • Dynamic Workflow Control: To adjust the flow of an n8n workflow based on conditions determined by AI agent input.
  • API Integration with Custom Logic: When integrating with APIs requires custom code for parsing responses or handling specific scenarios.
  • Automated Report Generation: Generate reports from data processed within n8n, incorporating dynamic elements and formatting.

Key capabilities

  • Execute JavaScript expressions in n8n workflows.
  • Run custom code snippets within an n8n workflow.
  • Interact with n8n's workflow engine programmatically.
  • Data manipulation and transformation within the n8n environment.

Example prompts

  • "Run this Javascript expression: JSON.parse(data) on the 'input_data' variable."
  • "Execute the following code to calculate the total price: price * quantity using values from variables 'price' and 'quantity'."
  • "Based on the value of 'status', execute either workflow A or workflow B in n8n."

Tips & gotchas

  • Requires an existing n8n instance and appropriate permissions to execute code.
  • Be mindful of security implications when executing user-provided code within n8n.
