Frontier packages the things an agent needs that are not the model: a place to hold shared organisational context, a permissions model scoped below the user, a feedback channel that persists across sessions, and connectors into systems where work actually lives. The product claim is that these belong together rather than being assembled per project, which is a claim about where integration cost sits rather than about capability.
Every element existed before, assembled by hand. Teams building agents already stood up a context store, wired scoped credentials, and built their own evaluation loop — typically as three separate projects with three separate owners. What changes is not possibility but the cost and consistency of assembly, and the fact that a vendor now has an opinion about the shape.
