- Comment @-mentions — Slack + email + outbound notificationsA comment that includes @<name-or-email> resolves the token against the workspace member roster (matches by first name, name slug, email local-part, or full email) and pings every matched teammate via Slack and email — fire-and-forget, never blocks the response. A new outbound webhook event task.mentioned fires alongside, so external CRMs/paging tools can mirror the alert. The TaskComments composer adds an inline mention popover that suggests the right token as the operator types after @. Closes the rev 26 silent-comment gap that made multi-operator teams' threads invisible until someone happened to look.
- @desk in a comment promotes it to authoritative AI directionType @desk in a comment and Loop Desk also calls addTaskOperatorNote() with the comment text (with the @desk token stripped). The next AI cycle reads it as authoritative direction, just like a rev-14 operator note. The comment itself stays in the teammate-only thread but gets an @desk → AI badge so the audit trail shows when chatter became direction. The bridge is one-way and explicit — the AI never sees regular comments, and a regular comment cannot accidentally become direction.
- Cmd/Ctrl + K command paletteFloating ⌘K button + global Cmd/Ctrl+K shortcut opens a typeahead palette covering navigate (Approvals, Active work, Recent signal, Memory, Desk health, Changelog, Docs), create (Hand the desk a task, Log a signal, Teach the desk, Add a source — all gated to non-viewer roles), and manage (Run desk now, Integrations + settings, Workspace members — gated to owner/admin). ↑↓ navigates, Enter runs. Layered on top of rev 17's / search shortcut and rev 23's g+ panel jumps for full power-user keyboard parity with Linear, Raycast, and GitHub command palettes.
- Richer empty states across Approvals, Active work, Memory, Recent signal, and SourcesReplaced the single-line .app-empty plain text with a new .app-empty-rich pattern: gradient panel + icon + title + helper copy + a ⌘K hint that points at the exact palette command needed to break the empty state. New workspaces saw five panels with thin one-line copy; rev 27 turns each into a small invitation that names the next step. Pairs with the rev-19 onboarding templates and the rev-11 activation checklist to make day-1 of a fresh desk feel guided rather than barren.
