Transitions - Persistence

Transitions are the edges out of a node. Add them from the node’s Transitions menu, then drag the handle to the next node.

Conversation transitions

Menu label	Default edge label	Use it when
Prompt	Prompt transition	The model should decide that this stage is done. Describe the exit condition in the transition text.
Condition (if)	If…	A variable rule should route without waiting on the model.
Else	Else	No other transition matched. One Else per node.
Before user response	Before user response	Leave the node before the caller speaks. Exclusive with other response-timed edges.
After user response	After user response	Leave the node after the caller speaks. Exclusive with other response-timed edges.

Before user response and After user response replace other transitions on that node. Use them for a short spoken line that must not wait on a prompt condition. You can reorder Prompt and If… transitions of the same type. Evaluation follows that order.

Condition rules

On Condition (if) transitions, and on Condition nodes, each rule has a field, an operator, and a value. Combine rules with Any or All of the following conditions match.

Operator	Label
`=`	Equals
`!=`	Does not equal
`>`	Greater than
`<`	Less than
`>=`	Greater than or equal
`<=`	Less than or equal
`contains`	Contains
`not_contains`	Does not contain
`exists`	Is present
`not_exists`	Does not exist

Use a variable reference for the field. Is present and Does not exist do not take a comparison value. Always provide Else (or If failed / If failed to call on extract and function nodes) for values you did not anticipate.

Function and extract edges

Node	Failure label
Function	If failed to call
Extract	If failed

Wire those edges to a recovery conversation, a transfer, or End call. Do not leave them unconnected.

Checklist before you publish

Start connects to the first speaking or action node.
Every conversation has at least one way out.
Every function and extract node has a failure edge.
Transfer and end nodes are the terminals you intend.
Prompt transition text describes a real exit, not a restatement of the node prompt.
