 Use the profile refresh control after installing, authenticating, or upgrading an agent. A manual refresh updates both the advertised models, modes, and commands and the visible capability status, so an old failure banner does not remain authoritative after the local CLI recovers.
 
-**Settings > Agents** shows **Subscription Usage** only when a supported host agent is signed in through a subscription plan. The current section covers Codex and Claude Code, reports the provider's plan and rate-limit windows, and can be refreshed on demand. It is an operational signal from the installed CLI, not a billing ledger or a guarantee that the next request will be accepted; provider availability, account policy, and concurrent usage still apply.

+When [Office mode](feature-status.md) is enabled, open **Office > Agents** and
+select an Office agent to see its **Subscription Quota** on the overview; the
+Office dashboard also summarizes the highest utilization across subscription
+agents. These cards appear only for supported subscription agents with provider
+credentials.
+
+For account-wide provider usage across supported providers, install the
+[Provider Usage plugin](https://github.com/kdlbs/kandev-plugin-provider-usage).
+It adds a provider pill to the session top bar and can add a compact display to
+the global status bar. The optional status-bar display requires **App status
+bar** to be enabled under **Settings > System > Feature Toggles**; enable it
+and restart Kandev for the change to take effect. If it remains disabled, the
+session top-bar pill remains available; enabling it also adds the global
+status-bar and phone Status drawer display. Configure the plugin under
+**Settings > Plugins > Provider Usage**. These usage surfaces are operational
+signals, not a billing ledger or a guarantee that the next request will be
+accepted; provider availability, account policy, and concurrent usage still
+apply.
