What

--permission-mode is a command-line option that picks the permission mode a session starts in, meaning how Claude Code asks before taking actions. At startup Claude Code turns that option into a request it sends internally. That request is now skipped when Claude Code is running in serve-only mode.

Why

In serve-only mode, the permission mode given with --permission-mode is not applied through this startup request.

When it does, it keeps the [dispatch defaults](#dispatch-defaults) you opened it with: `--model`, `--effort`, … agent-view see the edit
