Test your Blueprint

You test Blueprints directly in the Blueprint Editor. The Contents sidebar is the entry point: expand any Blueprint’s parameters, set its input values, and run.

​

Quick Run from the Contents sidebar

1. Open the Contents sidebar on the left of the editor.
2. Click the # N badge next to a Blueprint — N is the count of its parameters. The Blueprint expands to show its inputs and outputs in line.
3. Set values for the inputs. Each input has a control matching its type — a dropdown for enums, a number field for numbers, a text field for strings, and so on. Required inputs are marked.
4. Run the Blueprint. Either click run, or turn on Live mode and the Blueprint runs automatically every time you change an input or edit the logic.
5. Read the outputs. Each output shows its current value next to its name in the Contents sidebar, and the Outputs footer at the bottom of the Blueprint’s section in the document does too.

After a run:

• The execution path is highlighted on the embedded diagram, showing which branches and elements were visited.
• Each visited element shows a step number so you can see the order of execution.
• The trace controls in the top toolbar become active for stepping through the execution.

The Blueprint you set values on doesn’t have to be the active Execution Scope — you can quick-run any Blueprint in isolation to test it.

​

Live mode

The Live toggle in the top toolbar puts the editor into continuous-execution mode. While Live mode is on, Leapter re-runs the Blueprint automatically every time you change an input value or edit the logic. The Outputs footer of every section updates as you edit. Live mode is most useful for:

• Tweaking values — adjusting a threshold or rate and seeing every output update at once
• Reviewing edge cases — flipping a boolean input and watching which branch becomes active
• Pair-editing with AI — applying AI changes and confirming the outputs immediately
• Reading an unfamiliar project — turn it on and you can see real values flowing through every Blueprint as you scroll the document

Turn it off when you want to make several edits without intermediate runs.

​

Stepping through a trace

After any run, the trace controls in the top toolbar become active. They let you replay the execution one step at a time across every Blueprint that ran. While stepping, the active node is highlighted on whichever diagram contains it. Variable values at the current step are visible on the embedded diagram and in the Outputs footer. The editor is read-only while a trace is active — exit the trace to resume editing.

​

Autoplay

The trace toolbar also has a play / pause button and a playback speed control for animating through the trace automatically:

• Play — auto-advance through every step in order. The button toggles to a pause icon while running.
• Pause — stop the auto-advance at the current step. The button toggles back to the play icon.
• Speed — adjust how fast autoplay moves through the trace.

Autoplay pauses on its own as soon as you take manual control — clicking a step in the diagram, hitting prev / next, jumping to start or end, or stepping in or out. It also pauses automatically when the trace reaches its last step. The same play / pause + speed controls appear in embedded viewers (where you can opt-in via the autoplay attribute on <leapter-logic-viewer>) and in public read-only shares.
