What problem does it solve? Configuring n8n nodes fails when you don't know which fields are required for a given operation or why fields appear and disappear based on other values. This Skill teaches a progressive discovery workflow so you configure nodes correctly in 2-3 validation cycles instead of trial and error. ## Core Features & Use Cases - Operation-Aware Configuration: Explains how resource and operation choices determine required fields, with concrete examples for Slack, HTTP Request, Postgres, IF, Switch, and 15+ other common nodes. - Property Dependency Guidance: Deep reference on the displayOptions mechanism (show/hide rules, AND/OR logic) so you can diagnose why a field is hidden or conditionally required. - Progressive Discovery Workflow: Decision tree for choosing between get_node standard detail, search_properties mode, and full detail, covering 95% of cases with the lightest option. - Use Case: You switch a Slack node from operation "post" to "update" and validation fails. The Skill shows you that update requires messageId instead of channel, and how to verify requirements before reconfiguring. ## Quick Start Ask the AI to help you configure an n8n HTTP Request node that POSTs JSON to an API endpoint, including handling the sendBody dependency.
