The account line of an agent in a list: the My Agents tile and the “Continue
an existing agent” menu (SPEC_MY_AGENTS_TILES_AUTH_AND_HISTORY_2026_10_03.md §5.2).
The Claude agent’s shell prefix: agentmux-bashwrap as the CLI’s
CLAUDE_CODE_SHELL_PREFIX, which streams Bash output without the hook
rewriting the call (docs/specs/SPEC_BASH_STREAMING_VIA_SHELL_PREFIX_2026_10_10.md).
Backend half of the /btw slash command — a faithful recreation of
Claude Code CLI’s own native /btw: a fast, one-shot, tool-less answer
that is aware of the current conversation (via a text prefix, not
--resume), WITHOUT touching the asking pane’s persisted transcript and
WITHOUT blocking/queuing behind that pane’s own live turn.
