Spaces have not been publicly announced yet, as far as i can find. Spaces are intended as a top-level feature - a tab in the sidebar at the same level as chat itself. Spaces can be static pages or fullstack apps. Spaces have an identifier, a UI, and a set of typescript actions that run in the cell. The intended pathway for spaces to use inference is to call an inference API, ctx.inference.complete, that properly stamps and identifies all requests made from spaces. Spaces are communicable: there is machinery in the code on the VM with POST /spaces/share/{slug} to share, a dedicated space_share_review reviewer agent whose job it is to review shared spaces, and POST /spaces/v2/{slug}/save endpoints that allow consuming a Space by a slug. Spaces seem to be shared verbatim as code bundles, though the implementation of "Ideas" as prompt bundles suggests that might change. This is inferred from the prompt strings in the binary, since spaces aren't live yet and can't be tested, however there are strings suggesting that the LLMs rewrite and edit the prompt text for an Idea (stripping unsupported claims, etc.) but not a space. A space is a hashed bundle whose code is evaluated by a submit_space_share_review tool which only describes a thumbs up/down vote on whether the space is safe to share.

Ideas are intended to be prompt-only communicable things that can induce Spaces, or Space-like things, if the Idea warrants it. There is an ideas_builder agent class in a .toml file embedded in the binary. It materializes a prompt description into whatever that implies, if it's as simple as a scheduled message from the LLM great, but if it's something that warrants something that is Space-like like "build the user a dashboard to show them their pet photos, they love that!" then it's supposed to invoke the same artifact.create_web_fullstack tool that spaces use. The strings seem to indicate that "workspaces" is the antecedent of "Spaces," and that kind of thing is to be expected given that Spaces have not been released yet. So there are a few flavors of Ideas, one of them is a "Generated Idea" ("Activation-Authored Execution" which are supposed to improvise, adapt and materialize a prompt in the user's VM. and a "Workflow-Backed Ideas" are Ideas that come with a prescribed execution flow. Again I don't see "Spaces" described explicitly, but they reach for the same idea, call the same tools, do the same thing, and importantly for this example, have access to the same sockets.
