Variable nodes

Read and write arbitrary keys in the workflow context using dot notation. Values written here are visible to every later node as {{ <key> }} and survive a suspend/resume.

Set variable

@wf::variables:set · VariableSetNode

Field	Type	Notes
key	text	Required. Dot path to write, e.g. order.status.
value	json	Value to store. Supports {{ }}.

Output: { "key": "order.status", "value": "shipped" }

---

Get variable

@wf::variables:get · VariableGetNode

Field	Type	Notes
key	text	Required. Dot path to read.
default	json	Returned when the key doesn't exist.

Output: { "value": <value or default> }

---

Increment variable

@wf::variables:increment · VariableIncrementNode

Adds amount to a numeric value (treating a missing / non-numeric current value as 0) and writes it back.

Field	Type	Default	Notes
key	text	—	Required. Dot path to the number.
amount	number	1	Use a negative number to decrement.

Output: { "value": <new value> }

---

Append to variable

@wf::variables:append · VariableAppendNode

Pushes a value onto an array at key, creating the array if needed (a scalar already there is wrapped into an array first).

Field	Type	Notes
key	text	Required. Dot path to the array.
value	json	Value to append. Supports {{ }}.

Output: { "value": <the full array> }

---

Remove variable

@wf::variables:remove · VariableRemoveNode

Field	Type	Notes
