N8n Workflow API Authoring

This skill should be used when authoring an n8n workflow as JSON to import via n8n's REST API (rather than hand-clicking in the editor), when an n8n HTTP Request node's attached credential seems to be silently ignored, when an n8n Code node throws "Module 'X' is disallowed", when a `{{ }}` expression field throws a bare "invalid syntax", when downstream Code node fields go missing/undefined after an HTTP Request node, when importing/updating an n8n workflow via `POST`/`PUT /api/v1/workflows` hits errors like "active is read-only", "PATCH method not allowed", or a referenced error-workflow name not resolving, when a Wait-node-delayed check using `$getWorkflowStaticData` gives a stale/wrong answer, or when decoding n8n's SQLite `execution_data` for debugging without an API key. Trigger phrases include "n8n workflow JSON", "n8n REST API import", "n8n credential not working", "n8n expression invalid syntax", "n8n Module crypto is disallowed", "n8n HTTP Request neverError", "n8n workflow active read-only", "POST /api/v1/workflows", "getWorkflowStaticData stale", "n8n Wait node static data", "n8n execution_data flatted decode".
