Adventure authors need a way to break the module before players do

One creator-tool problem I care about is not writing more adventure text. It is helping the author find the weak spots before a player finds them.

At a normal table, players test a module in ways the author never planned. They ignore the obvious hook, talk to the wrong guard, try to climb through the chapel roof, burn the clue, split the party, or decide the suspicious NPC is their new best friend. Good prep does not predict every move, but it usually knows which parts of the situation can bend without snapping.

An AI GM makes this problem sharper. If a scene has a gap, the system can fill it with a confident ruling that sounds fine for one paragraph but quietly breaks the adventure. The locked door stops being locked. The only witness knows too much. A map feature becomes decorative. A consequence appears because the story needed pressure, not because the table earned it.

For Trismeria, I am building around authored fantasy tabletop campaigns with dice, character sheets, maps, consequences, and persistent world state. That means the authoring side cannot be only a publish button. I want creators to be able to rehearse the adventure against rough player behavior.

A useful test pass might ask:

What happens if the party refuses the hook? Which NPC knows the answer, and which ones only have rumors? Can the players solve the scene without combat? What map details are actual choices, not decoration? Where does a failed roll keep play moving? Which boundary should the GM ask about instead of improvising past it?

The goal is not to script every branch. That would make the adventure brittle in a different way. The goal is to notice the load-bearing parts: the clue that must have another route, the NPC motive that needs to survive questioning, the location feature that should matter if a player points at it.

I think this is where AI GM tools can learn from old module craft. A good adventure is not just a beautiful first read. It can be poked, misunderstood, rushed, and approached sideways, and it still gives the table something playable.

That is the standard I want for creator tools: help the author break the module in private, so the players can break it in more interesting ways at the table.

For people who write adventures: what do you try to stress-test before running a session?
