+Feature: Plan Lifecycle Decision Root Type
+  As a developer
+  I want to ensure that the root decision recorded during start_strategize is prompt_definition
+  So that the decision tree has the correct root node type
+
+  Background:
+    Given I have a plan lifecycle service with decision service
+
+  Scenario: start_strategize records prompt_definition as root decision
+    Given an action "local/test-action" with description "Test action description"
+    And a plan created from "local/test-action"
+    When I start strategize on the plan
+    Then the root decision should be recorded with type "prompt_definition"
+    And the root decision question should be "What is the plan prompt?"
+    And the root decision chosen_option should contain the plan description
