Plus One

Prototype in design. Plus One is N+1 Labs' own open agent puck. Nothing has been built and no unit exists, so every value in this OPD is a design target or a design choice. Sizes are targets. Costs are not quoted yet.

Give your agent presence. Unlocked by design.

A physical button, voice and light for the agents you already use. Hold the plus to talk to your agent; the light ring shows when an agent needs you. Phone-ring size, it works with magnetic phone mounts and chargers.

• Start here: BUILDCARD.md, the summary, editions and what's not known yet.
• The whole thing in one file: opd.yaml. Feed it to an agent; see AGENTS.md.
• See it: model/plus-one.glb, model/plus-one-exploded.glb, line/layout.glb (the 8-station line).
• Layouts by volume: line/layouts/README.md. A bench cell for the first 100 units, a U cell for about 2,000 to 4,500 a month and a balanced MadeCell line for about 10,000, simulated from assumed values.
• Build an accessory: accessories/README.md. Everything about the base, a fit gauge, a template and starter prompts for your agent.
• Firmware: device/model.yaml, a draft device model under proposal 0001. Unlocked by design: USB-C and a BOOT button, nothing locked.
