A field guide to the five patterns that nearly every useful n8n workflow is a variation of: webhook processing, HTTP/API integration, database operations, AI-agent workflows, and scheduled tasks.
Instead of a node reference, this is architecture — for each pattern you get the canonical node chain (e.g. Webhook → Validate → Transform → Respond), a plain-English "use this when…", and the failure modes to guard against. It's the map that stops you from wiring a fragile one-off when a proven shape already exists.
How to use: open README.md for the pattern-selection guide, then read the pattern file that matches your automation. Each pattern file is standalone — skim the one you need. Bring it to Claude/Cursor as context when you ask an agent to build a workflow.
