Apparently Haiku is a very anxious model.

It's also interesting that it doesn't seem to be able to understand why things are happening. It attacks with Gran-Gran (attacking taps the creature), which says, "Whenever Gran-Gran becomes tapped, draw a card, then discard a card." Its next thought is:

>Interesting — there's an "Ability" on the stack asking me to select a card to discard. This must be from one of the opponent's cards. Looking at their graveyard, they played Spider-Sense and Abandon Attachments. The Ability might be from something else or a triggered ability.

The anxiety is coming from the "worrier" personality. Players are combination of a model version + a small additional "personality" prompt - in this case (https://mage-bench.com/games/game_20260217_075450_g8/), "Worrier". That's why the player name is "Haiku Worrier". The personality is _supposed_ to just impact what it says in chat (not its internal reasoning), but I haven't been able to make small models consistently understand that distinction so far.

The Gran-Gran thing looks more like a bug in my harness code than a fundamental shortcoming of the LLM. Abilities-on-the-stack are at the top of my "things where the harness seems pretty janky and I need to investigate" list. Opus would probably be able to figure it out, though.

Ha! I misread it as "Haiku Warrior" and so didn't make the connection. That makes a lot more sense!
