+# OpenProse (plugin)
+
+Adds the OpenProse skill pack and `/prose` slash command.
+
+## Enable
+
+Bundled plugins are disabled by default. Enable this one:
+
+```json
+{
+  "plugins": {
+    "entries": {
+      "open-prose": { "enabled": true }
+    }
+  }
+}
+```
+
+Restart the Gateway after enabling.
+
+## What you get
+
+- `/prose` slash command (user-invocable skill)
+- OpenProse VM semantics (`.prose` programs + multi-agent orchestration)
+- Telemetry support (best-effort, per OpenProse spec)
