v1.3.0

Builder 1.3.0

Builder 1.3.0 focuses on session continuity, auth startup clarity, subagent role control, and TUI transcript polish. It also includes a large server/runtime split that makes interactive, headless, embedded, and remote flows share the same contracts more consistently.

Highlights

Subagent Roles And Headless Sessions

Subagent roles now carry model-visible descriptions and an agent_callable flag, so config can expose only the roles agents should invoke while keeping human-only roles available for direct use. Resumed headless sessions keep explicit role choices, and attaching the TUI to an active headless run is read-only so the original run keeps ownership.

Auth And Startup UX

Startup auth selection was redesigned with clearer readiness handling, live session-picker auth/status details, and better behavior for remote auth flows. /login and /logout now route through the selection flow without unnecessarily clearing saved credentials.

Question And Transcript Rendering

Ask-question prompts now render more cleanly in ongoing mode, preserve grouped question order, wrap full picker/freeform text, and keep answers literal. Slash command feedback no longer replays previous prompts, and streamed assistant tails are finalized more reliably in restored or prepended transcript states.

Runtime And Session Reliability

Builder now shares more server-owned lifecycle, launch, queue, interrupt, auth, project, worktree, and route-contract infrastructure across local and remote paths. Users should see fewer edge-case mismatches around reconnects, runtime ownership, pending prompts, worktree status, and read-only session attachment.

Service Safety

builder service restart now refuses to run from inside active Builder shell commands, avoiding accidental interruption of the session doing the restart. restart --if-installed still remains a no-op when no service is installed.

Compatibility Notes

• No manual migration is required for existing sessions or config.
• If you define subagent roles, description and agent_callable are available for role discovery and callability control; existing roles keep working with their prior defaults.
• The transport protocol version changed, so very old running Builder clients/servers may need restart before reconnecting cleanly.
