Remove the remaining shell glue from the canonical CLI workspace flows so users can hand off IDs and host-authored text files directly.
Add --id-only on workspace create and shell open, plus --text-file and --patch-file for workspace file write and patch apply, while keeping the underlying SDK, MCP, and backend behavior unchanged.
Update the top walkthroughs, contract docs, roadmap status, and use-case smoke runner to use the new shortcuts, and verify the milestone with uv lock, make check, make dist-check, focused CLI tests, and a real guest-backed smoke for create, file write, patch apply, and shell open/read.
Extend the chat-ergonomics roadmap with the remaining UX work highlighted by the readiness review.
Document a second pass focused on removing shell glue from canonical CLI handoff flows, making the recommended chat-host profile more obvious without changing 3.x compatibility defaults, and polishing human-mode content reads for cleaner transcripts and copy-paste behavior.
Keep these milestones explicitly workspace-first and scoped to product UX, with CLI-only shortcuts allowed where the SDK and MCP surfaces already provide the structured behavior natively.
