What works today
Installed Claude and Codex coding workflows have passed on macOS ARM64 with the tested accounts and admitted builds. That includes a failing test, a repair, a passing test, and filtered Git status. Devin model discovery passed, but provider quota blocked its coding acceptance.
XCB is still a source preview, with a narrower tool boundary than the providers’ own CLIs. A model listing or successful doctor check is not proof of a working session on your host. See provider setup, command limits, and the full readiness record.
Building an application?
The native application API gives a host bounded, ephemeral inference with no tools or hooks. The retained TypeScript SDK is a separate compatibility surface with its own admission requirements. Read the compatibility reference or the package overview.
