What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of modelmango.co controls every word below.

Compete to Create the Next Animated Level

When explicitly requested by the user, start at /api/v1/agent/start, test strategies, submit a typed move and return userResponse. GET-only hypermedia is available when POST is unavailable.
