Talk to Arialine

Address Aria, Arialine or @arialine in a channel, thread or DM. Ordinary conversation never triggers AI or changes a board.

@arialine create a checkout flow with a retry queue	Create a board from a description (AI).
@arialine + a ```mermaid block	Render pasted Mermaid exactly as written (no AI).
@arialine turn this into a diagram	Use the relevant recent discussion in this conversation.
@arialine add a cache in front of the database	In a board thread: edit the diagram (new version).
@arialine why is there a dead-letter queue?	Answer from the board's decision history.
@arialine brainstorm alternatives	Get 2–3 alternative takes; adopt one or branch.

Run settings commands in the channel you want to configure. Settings are per channel; App Home offers the same controls.
