Static Interrupts (Debug Breakpoints)

This example demonstrates static interrupts (debug breakpoints) in the graph executor.

Unlike Human-in-the-Loop (HITL) interrupts where you call graph.Interrupt(...) inside a node, static interrupts require no code inside the node. You only attach options when declaring nodes:

• graph.WithInterruptBefore() pauses before a node executes.
• graph.WithInterruptAfter() pauses after a node executes.

What you will see

This workflow has three nodes:

1. start runs normally
2. middle has both WithInterruptBefore() and WithInterruptAfter()
3. end finishes the workflow

So the program runs three times:

1. Interrupts before middle
2. Resumes, runs middle, then interrupts after middle
3. Resumes again and completes at end

Run

go run .

Notes:

• This example uses the official in-memory checkpoint saver, so resume happens within the same process run.
• For a persistent resume workflow (restart the program later), use a real saver such as SQLite or Redis.
