+description: List carts, show the active one, or switch carts in-process
+---
+
+The user invoked `/cart` with argument: `$ARGUMENTS`
+
+Handle it as follows, calling tools directly and reporting back tersely:
+
+- **Empty / `list` / `ls`** → call `cart_list` and `cart_info`. Render a compact
+  table with columns: `slug`, `name`, `voice` (or `-`), `version`, `★` (mark the current one).
+  Append a one-line totals summary.
+
+- **`current` / `active` / `?`** → call `cart_info` and report just `slug` + `name`
+  (and `voice` if set). One line.
+
+- **`main` / `eems` / `base`** → call `cart_load` with no `slug` argument. Confirm
+  the swap by echoing the returned `slug`, `name`, and `path`. One line.
+
+- **Anything else** → treat as a cart slug. Call `cart_load` with `tag="$ARGUMENTS"`.
+  On success, echo the new active `slug` + `name` + `path` (one line). On error (typo, cart
+  not found), surface the error string verbatim and suggest `/cart list`.
+
+Rules:
+- Don't narrate ("I'll now..."). Just call tools and report.
+- No more than 6 lines of output total (table can exceed if many carts).
+- Don't call any other tools — cart ops only.
+- Remember: this is an **in-process** swap. opencode chat history is shared across carts;
+  only EEMS data is isolated. Don't restate this every time — only mention it if the user
+  switches into a different cart for the first time in this session.
