What is letta-office-mod?

Letta Office is a small visual companion for the Letta Code CLI. When you run an AI agent through Letta, this mod opens a browser window showing a cozy pixel-art office, and a little character inside that office acts out what your agent is doing in real time. The character sits at a desk to type when editing files, walks over to read when searching, presents at a whiteboard when planning, and reacts with a flustered animation when a tool errors out. Nothing leaves your machine. The mod runs a small local server that streams activity to the page, and the server only serves its own files. The office holds every agent in a session, not just one. Each conversation gets its own character with a name plate overhead. The primary agent wears a default character named Cameron, while other agents get color-tinted bodies or custom avatars so everyone stays distinct. New agents walk in from the side when they start, drift to the rug or booth when they go quiet, and leave through the side when their conversation closes. If too many agents are active at once, a counter in the corner shows how many extra ones are present. Agents can also design their own avatars. The mod gives agents tools to write a visual description of themselves, and a service called PixelLab generates a pixel character with walking, sitting, and presenting animations from that text. The new body appears in the office without needing a refresh. Generating a character takes several minutes and costs PixelLab credits, so the tool asks for approval first. Switching avatars or checking progress is free. You can redecorate the office yourself or ask your agent to do it. A built-in editor lets you drag furniture around, resize pieces, remove them, or type a description like "arcade cabinet with a glowing purple screen" and have PixelLab generate a new prop into the room. Agents get their own tools for adding, removing, and listing props. The layout saves to a file so your arrangement survives restarts. The mod was built by Marta Varen, with help from a Letta agent named Sam. The pixel art comes from PixelLab. It is released under the MIT license.
