Space Agent is different from every other AI assistant: instead of being trapped inside a fixed product, the agent can reshape the interface itself — writing new pages, tools, widgets, and workflows directly into the running workspace while you work. It runs entirely in the browser layer, whether you open it in a tab or through the desktop app.Documentation Index

Why Space Agent
Self-Modifying Interface
Ask the agent to build a page, tool, or widget — it writes it straight into the running workspace. The interface grows with your needs.
Browser-First Runtime
The agent lives in the same frontend layer it reshapes. No server round-trips for agent logic — it works directly with the framework, modules, and UI.
Layered Customware
Three layers: L0 firmware (immutable), L1 group customware, L2 user customware. Users build in their own layer without affecting anyone else.
Skills via SKILL.md
New capabilities live in plain
SKILL.md text files the agent can write and extend itself — no compilation, no deployment.Spaces and Widgets
Persistent workspaces with drag-and-drop widgets. Each space is a canvas the agent can populate with live tools and data views.
Git-Backed Time Travel
Every writable layer has optional local Git history. Roll back user or group changes without affecting anyone else.
