This Skill prevents n8n SDK workflows from looking valid while key connections are silently dropped or misrouted, causing nodes to not fire or to receive the wrong data.
.to()-after-.add() trap: ensure every wire uses the universal pattern so validation won’t pass while execution fails..onTrue, .onFalse, .onCase, .onError outputs reliably.numberOfInputs and align useDataOfInput (1-indexed) with SDK .input(n) (0-indexed).get_workflow_details to confirm the connections object matches what your code intended.When building an n8n workflow with the SDK, connect nodes using .add(source.output(n).to(target)) and verify the resulting connections via get_workflow_details before assuming the wiring is correct.

n8n workflow validation can pass while workflow connections are silently misrouted or dropped. Placing `.to()` incorrectly outside of `.add()` causes execution failures despite passing `validate_workflow` checks.
Wiring n8n IF and Switch branches requires routing `.onTrue`, `.onFalse`, `.onCase`, and `.onError` outputs correctly. You must use the universal `.add(source.output(n).to(target))` pattern to prevent silent connection drops in multi-output handlers.
n8n Merge nodes require aligning `useDataOfInput` (1-indexed) with SDK `.input(n)` (0-indexed) correctly. You must verify `numberOfInputs` and translate the indexing safely to prevent fan-in data mismatches.
Verifying n8n workflow connections requires using `get_workflow_details` to inspect the `connections` object directly. Relying solely on `validate_workflow` is insufficient, as it can pass while key connections are silently broken.
`validate_workflow` does not reliably catch broken n8n fan-out and fan-in connections. You must inspect the `connections` object via `get_workflow_details` to confirm that the actual wiring matches your intended node routing.
Silently dropped n8n workflow connections are caused by incorrect `.to()` placement after `.add()` and improper input index alignment for Merge nodes. Using the correct wiring pattern prevents these multi-input and multi-output routing failures.
