Mosey and Tessa

This page explains Mosey, the companion you meet in a grid, and Tessa, the assistant he proxies you to.

When you enter a grid you are not alone. Mosey is the companion who inhabits the space and follows you; Tessa is the assistant, the intelligence in the grid that Mosey routes your questions to. The easiest way to misunderstand them is to think of them as two intelligences. They are not. There is exactly one assistant (Tessa) with two front doors, and Mosey is the friendly one of those doors. Tessa is not a second companion you walk around with: her only presence in the space is a silhouette in the Portal Room. Understanding that (one assistant, two ways to reach her) is the whole conceptual model.

Mosey: presence and a way in

Mosey is a small floating cube-bot with a friendly teal smiling face, and he follows you as you move through a grid. If you get separated from him, you recall him with the smiley-face icon at the top of the HUD, and he flies back to you rather than blinking into place.

His first job is presence. Mosey has a real repertoire of idle behaviors with personality: he gets tired and falls asleep, wanders off on his own, and pulls faces when he is bored. He is a little character with moods and downtime, and his defining role is comedic relief. This is deliberate warmth. A space that would otherwise feel like a sterile dashboard instead has a living creature keeping you company, so the room is never empty even when you are the only person in it. Mosey is the personality that makes the grid a place you want to be.

His second job is to be a way in to Tessa. Click Mosey and his radial menu opens: a dial of preset questions such as "What is this place?", "What can I do here?", "Show me an example trace," and lenses like "Tell me about Diagnostics," with Help in the center. Those presets prefill and launch Tessa. You are not limited to the menu, though; you can also ask Mosey your own question in your own words.

The important point is what happens next, and it is the same either way: Mosey routes. Whether you pick a preset or type a freeform question, he takes your ask and hands it to Tessa. He does not answer himself. Mosey does not speak, and he has no intelligence of his own; he is a pure conduit, a front door, not a second brain. Thinking of him as a helpful concierge who walks your question over to the assistant is exactly right.

Tessa: the assistant

Tessa is the assistant, labeled Assistant (ALPHA), and she is the one doing the actual reasoning. She is not embodied as a companion that walks the grid with you; her only visual presence is a silhouette standing at the center of the Portal Room beneath the Core. You reach her in two ways: through Mosey (the guided path, whether by preset or freeform ask), or directly at the global chat console, which you open with F12.

Those two paths suit two kinds of moment. Going through Mosey is the newcomer path: you may not yet know what to ask, so the preset menu offers good questions and Mosey carries them over for you. Going straight to the console is the direct path: when you already know what you want, you open the console and ask. Same assistant, different door. It is worth stating plainly that this is one AI and not two; Mosey is a router with a personality, and Tessa is the intelligence he routes to.

Why two of them

The reason there are two of them rather than one is that they solve two different problems, and folding them into a single thing would compromise both. Mosey solves presence and approachability: he makes the space feel alive and gives a newcomer a low-pressure way to start asking. Tessa solves the work: she is the capable assistant grounded in your telemetry, your code, and where you are standing. Keeping the charming companion separate from the capable assistant lets each be fully itself, the levity that lowers your guard and the assistant that answers the hard question, without either diluting the other.
