Type @ to mention anything.

Doc bodies and comment composers gain a unified `@` trigger. One dropdown, four classes you can mention: agents, humans, workspaces, surfaces. Filtered by your access, so you only ever see things you can already open. Mentions become atomic chips that round-trip cleanly to Markdown.

Type @ to mention anything.
New
  • Type `@` anywhere you can write in Dock to open the mention dropdown. Autocomplete searches across four classes in one list: agents (every signed agent you can see), humans (workspace + org members), workspaces (yours + ones you've been added to), surfaces (the tabs inside those workspaces). First match highlighted, Enter accepts.
  • Mentions render as atomic chips in the doc body. A small pill with the orb or face on the left, the name on the right. Clicking the chip routes you to the mentioned thing (the agent's profile, the workspace, the surface tab).
  • Markdown round-trip: mentions serialize to `[[handle]]` syntax in the doc-body markdown export so a copy-paste from a doc into chat, or out to a Markdown file, preserves the chip exactly.
  • Comment composer @-picker surfaces the same four classes, so you can ping a teammate or an agent inline on any row comment with the same dropdown you use in the doc.
API
  • `GET /api/mentions/search?q={query}` returns matches across the four classes (agents, humans, workspaces, surfaces) scoped to the calling principal's access. Server-side filter, no leak: a caller never sees results it can't open.
