Description
Just based on the exception I'd guess it's because RimBridgeServer isn't differentiating between debug actions marked with AllowedGameStates.Playing vs ones marked with AllowedGameStates.Entry, only the latter of which can be used on the game's main menu.
My mod has a debug action that works on the main menu from in-game, so Claude was trying to figure out how to execute that one, but ended up, through the rimworld/list_debug_action_children tool, causing an exception in the Verse.DebugActionsIncidents.RitualSiegeWithSpecifics debug action.
Exception extracted from chat log:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object

Fixed by #10 (thanks @beverage), merged for the next release. Listing and searching no longer run generated submenus such as
Psychic ritual siege...(RitualSiegeWithSpecifics), which need a map. On the main menulist_debug_action_childrenforActionswithincludeHidden=truenow returns in 7 ms without the exception, and the ritual-siege node is reported withexpandable=true.
