This is an agent skill (SKILL.md) that guides an AI coding agent when writing JavaScript for n8n Code nodes. It bundles reference docs covering data access ($input/$/$node), execution mode selection, return formats, HTTP helpers, DateTime, error patterns, and production gotchas.
Reach for it whenever a workflow needs a Code node or when diagnosing slow or failing Code node JavaScript in n8n.
Use it to
- Write or debug JavaScript in an n8n Code node
- Choose between Run Once for All Items vs Each Item modes
- Make HTTP requests via this.helpers.httpRequest in the sandbox
- Aggregate, filter, or transform items across SplitInBatches loops
- Diagnose why a Code node or workflow is slow
