@handles and /commands.
Two ways to be specific, on purpose different. An @handle is a reference: it loads that thing’s capability card — its tools, its docs, whether a call can be undone — so the conversation carries fourteen tools instead of hundreds. A /command is a platform verb run as written, with no model involved: /deploy, /logs, /restart, /rollback.
- A mention stays pinned to the conversation until you dismiss it.
/is a keystroke,@is a conversation.- An unknown handle never fails silently — it answers with the nearest three.
