Edges

Edges connect nodes and decide what happens next. Use them to create linear paths, conditional logic, and safe fallbacks.

Types of edges

• Default — always go to the next node.
• If — go to the next node only when a condition is true.
• Else — fallback route when no prior If edges matched.

When to use which edge

• Default: simple, linear flows; single next step.
• If: branching based on state (intent, confidence, tool result, flags).
• Else: graceful fallback when no conditions match.
