Step Insights & Debugging

Walk through an Evaluation run step-by-step to inspect every decision

Step Insights & Debugging

After an Evaluation run, the Step Insights panel opens on the right side of the simulation page. It's a full step debugger — jump to any step, walk forward and backward, and see exactly what happened.

Navigation

The top of the panel shows Step X of Y and a jump-to-step input.

  • Jump input + Go — type a step number, press Enter or click Go to jump directly.
  • ← / → — walk one step backward or forward.
  • Shift + ← / → — step over a sequence. If you're inside a sequence, Shift+→ jumps past its remaining siblings; on a sequence container, Shift+→ skips all children.
  • ESC — close the panel.

What each step shows

For every step, the panel displays:

  • Executing node — the node's name, ID, and type.
  • Sequence context — which sequence this step belongs to, with a child-count badge.
  • Master seed + derived seed — the top-level seed and the seed actually used for any randomized decision in this step. Useful for reproducing specific outcomes.

Behavior node insights

When the current step is a Behavior node, the panel shows which outcome was picked and the probability it was drawn with. If the outcome's chance was dynamic (driven by a variable), you can see the exact value that produced the probability.

Datapoint changes

Every change in this step is categorized:

  • Currency — balances that went up or down
  • Resource — non-currency consumables
  • Item — item counts granted or consumed
  • Statistic — trackable counters (wins, kills, …)
  • Tag — anything tagged metadata

Each entry shows the datapoint name, the delta, and the new value.

Deep Dive into sequences

When the current step is a Sequence container, a Deep Dive button appears. Click it to step into the sequence's first child. Use Exit Sequence (or Shift+→) to skip past the sequence's children and jump to the next sibling.

Tip: Pin the seed in the Runner before debugging a flaky behavior. With a fixed seed the same step will produce the same outcome on every run, so you can edit the graph and re-run without losing your mental map.
