Deciding factorYou need the recent, informal, thread-level context.versus: You need the durable, searchable, moderator-reviewed answer.
Bottom line
Slack for what was said; Discourse for what was decided.
The short answer
Slack is where decisions happen and disappear; Discourse is where they are kept. An agent reading Slack answers 'what did we say last week' quickly and unreliably. An agent reading a forum answers 'how do we do this' slowly and accurately. Different questions, different indexes.
