AGNTCon + MCPCon Japan 2026

Every agent system is two things: the model, which you rent, and the mask - the character - which is yours. The industry keeps upgrading the model and expecting the mask to improve. It doesn't work that way.

I'm a LAMDA-trained actor turned agent engineer. This talk is the actor's toolkit applied to shipped systems. Case one: a comms pipeline in production at a major crypto protocol - the generating model does Stanislavski table-work (super-objective, through-action, lining) before writing a word; a separate director model audits it blind; and voice is scored by a Laban Movement Analysis classifier that grades the human-written corpus and the machine's output on the same instrument. Brand voice becomes a falsifiable measurement. Case two: the home lab - eleven agents built with a Stanislavski character method, orchestrated over MCP, running my actual work.

You'll leave with the model/mask distinction, a character pipeline you can copy, and the failure modes: drift, voice collapse, paint-by-numbers slop.
