Use a Slack discussion as diagram context

Open the message menu, choose More actions, and select Render discussion as diagram. Arialine uses the discussion around that message as context: the message, its replies, and the channel context available to the app. A 24-hour relevance window and topic-gap filtering keep unrelated conversation out, with a safety cap on context size.

For a precise result, mention Arialine directly in the message or use the message shortcut. Ask for a diagram, Mermaid source, or a focused change, and review the proposal before applying it.

A direct reply can continue an already-grounded Q&A answer in its thread. Ordinary replies in a board or channel thread stay as context and do not invoke Arialine by themselves; explicitly address Arialine when you want a new action.
