N8N Workflow Troubleshooter

N8N Workflow Troubleshooter is a skill designed for developers and automation engineers who maintain n8n workflows in production environments. When a workflow fails or becomes stuck, manual debugging typically involves checking logs, inspecting Docker container states, and toggling workflows on and off to reset internal state. This skill automates that diagnostic process by identifying common workflow execution failures, verifying that Docker dependencies required by n8n are in a healthy state, and applying deactivate/reactivate cycles to workflows that are stuck and unresponsive. The skill targets n8n power users who run workflows in production and need to resolve errors quickly without iterating manually through each possible failure point. It does not require environment variable configuration based on the available facts. Because no individual tools are listed for this skill, its behavior is encapsulated entirely within the skill logic rather than exposed as discrete callable functions. This makes it appropriate for agent workflows where the goal is rapid triage of n8n errors rather than granular programmatic control over specific n8n API endpoints. It is not a general-purpose n8n management interface and does not cover workflow creation, editing, or deployment.
