+Clawdbot can surface provider usage/quota when OAuth/API creds are available.

+Surfaces:
+- `/status` (adds a short usage line when available)
+- `clawdbot status --usage` (prints full provider breakdown)
+- macOS menu bar (Usage section under Context)

+Notes:
+- Data comes directly from provider usage endpoints (no estimates).
+- Providers: Anthropic, GitHub Copilot, Gemini CLI, Antigravity, OpenAI Codex OAuth, plus z.ai when an API key is configured.
+- If no matching credentials exist, usage is hidden.
+- Details: see [Usage tracking](/concepts/usage-tracking).
+
 ### `health`
 Fetch health from the running Gateway.

+- Pulls provider usage/quota directly from their usage endpoints.
+- No estimated costs; only the provider-reported windows.
+
+## Where it shows up
+- `/status` in chats: adds a short “Usage” line (only if available).
+- CLI: `clawdbot status --usage` prints a full per-provider breakdown.
+- macOS menu bar: “Usage” section under Context (only if available).

+- **Anthropic (Claude)**: OAuth tokens in auth profiles.
+- **GitHub Copilot**: OAuth tokens in auth profiles.
+- **Gemini CLI**: OAuth tokens in auth profiles.
+- **Antigravity**: OAuth tokens in auth profiles.
+- **OpenAI Codex**: OAuth tokens in auth profiles (accountId used when present).
+- **z.ai**: API key via env/config/auth store.

 - The “Nodes” block in the menu lists **devices** only (gateway bridge nodes via `node.list`), not client/presence entries.

 ## State model
 - Sessions: events arrive with `runId` (per-run) plus `sessionKey` in the payload. The “main” session is the key `main`; if absent, we fall back to the most recently updated session.
