When a user enters a multiline question such as /btw first line\nsecond line, ChatInput's /^\/btw\s+\S/ gate routes it to onSideQuestion, but this parser returns null because . does not match line terminators. The handler therefore neither starts the side question nor falls back to the normal send, so pressing Enter silently does nothing; parse the remaining text across newlines or share the exact parser with the send gate.

The slash picker explicitly supports triggers anywhere after whitespace, so selecting this item in hello /b produces hello /btw and skips token registration. ChatInput only intercepts values whose trimmed text starts with /btw, causing the resulting text to be sent as an ordinary primary-chat message instead of a side question; client-handled /btw must only be offered or selected when its trigger is at the start of the composer.
Useful? React with 👍 / 👎.

Registering /btw in the global built-in list also exposes it through /api/commands/suggest to ChannelInput, which embeds ChatTextarea and its command picker but has no side-question interception. Because this item is client-handled, selecting it inserts untracked literal text, and ChannelInput.handleSend posts /btw ... directly into the channel or DM; the suggestion needs a surface capability gate or must be filtered from non-AI composers.
Useful? React with 👍 / 👎.

This hook instance survives dashboard agent/conversation switches, but useSideQuestion only aborts its controller when conversationId changes and never clears state. Consequently, a completed answer from the previous conversation remains displayed under the newly selected chat, while an aborted in-progress card remains stuck on “Thinking…” because the abort path deliberately skips state updates; clear or key the side-question state whenever the conversation changes, including the identical sidebar mount.

Follow-up to #2678.
/btwworked only in the agent console: the dashboard assistant and right-sidebar chat blocked it while streaming and posted it as a literal message when idle, and the/picker never offered it on any surface.Surface wiring (contract preserved exactly)
GlobalAssistantViewandSidebarChatTabeach get their ownuseSideQuestioninstance, renderSideQuestionCardabove the composer, and passonSideQuestiontoChatInput— same shape as the console. Detached stream, independent abort, no persistence, never touches the primary chat lifecycle oractiveStreamId.SessionChatswitches to the sharedparseSideQuestionInputinstead of an inline regex — one parse for all three surfaces, so the ChatInput gate (/^\/btw\s+\S/) and the parse cannot drift.ChatInputitself is untouched.Picker discoverability

Plain text is required: a chip serializes to/[btw](builtin:btw)on send and would never match the composer interception.
