What it does

This skill provides a robust framework for programmatically patching n8n workflows via the n8n REST API. It automates the complex process of fetching workflow JSON, identifying specific nodes by type or name, applying precise structural or parameter modifications, cleaning the JSON of read-only metadata, and updating the workflow on the server.

Problem it solves

Manual management of large-scale n8n installations is prone to error and time-consuming. When you need to migrate APIs across dozens of workflows (e.g., switching from Ollama to Grok), downgrade deprecated Code node versions, or update authentication headers globally, doing it by hand in the UI is a nightmare. This skill handles the API logic, header management, and data cleaning required to perform safe, mass updates.

Key Features

• Automated migration logic (API endpoint swapping, model name replacement).
• Read-only field sanitization to prevent PUT request failures.
• Support for mass updates across all active workflows.
• Workflow activation/deactivation management via API.
• Version control friendly workflows (typeVersion patching).

Why use this skill

Instead of manually clicking through the n8n canvas for every change, this developer-centric skill allows you to treat your workflows as code. It understands n8n's specific API quirks—like which fields must be stripped before a PUT request—saving you from common "Forbidden" or "Internal Server Error" responses that occur when sending read-only metadata back to the server.
