Capabilities

Capabilities covers the state of this feature: sandboxing is not part of v3, so there is no capabilities= argument on Agent and no page here can make one exist.

The spec classes this page used to document field by field — CapabilitiesSpec, ShellSpec, FilesystemSpec, MemorySpec, CompactionSpec — have been removed from the codebase along with the rest of the sandbox scaffolding. Nothing constructed them, so nothing imports them. Read them in the git history if you need the shape they had; this page comes back when the feature does.
