Save or update a workflow profile that binds a workflow_kind (support_inbox | incident_room | exec_brief | product_launch_watch | custom) to channels, priority people, retention mode, and summary cadence. Stored locally at ~/.slack-mcp-workflows.json. Hosted brain reads these to return structured JSON per the workflow_kind.

List all saved workflow profiles from ~/.slack-mcp-workflows.json. Optionally filter by workflow_kind. Returns profile_name, channels, priority_people, retention_mode, summary_cadence, structured_keys, created_at, updated_at.

Catch up on a saved workflow profile. Reads the profile's channels (or everything currently unread if the profile names none), pulls messages since the cadence window or an explicit `since`, expands active threads, and returns structured evidence: which threads are unanswered and for how long, what the profile's priority people said or were pinned on, and which conversations moved most. Runs locally against your own session — no hosted account, no server-side model. The response carries an `output_contract` naming the keys to compose for this workflow_kind; write the summary from the returned `signals` and `conversations`, citing conversation names and timestamps.
