 ## What You Get
 
 - A **5h** bar for your current 5-hour Claude usage window
 - A **7d** bar for your current 7-day window
 - Optional Codex usage bars alongside Claude Code
 - Optional Antigravity model usage bars for Google's 5-hour and weekly Gemini quota windows
+- Optional OpenCode Go usage bars for your local 5-hour and weekly dollar limits
 - A live countdown until each limit resets
 - A small native widget that lives directly in the Windows taskbar
 - System tray icon badges showing your enabled model usage percentage

 Antigravity support is optional too. To show Antigravity usage, install and sign in to Google Antigravity, then enable the **Antigravity** model from the right-click **Models** menu.
 
+OpenCode Go support is also optional. To show OpenCode Go usage, install [OpenCode](https://opencode.ai) and sign in to a [Go](https://opencode.ai/go) subscription. Then enable **OpenCode** from the right-click **Models** menu.
+
+**Recommended — dashboard credentials (server-side accuracy):** the monitor reads your real Go usage (5h and weekly windows, with server-side reset times) from the OpenCode dashboard at `https://opencode.ai/workspace/<wrk_id>/go`. To do this it needs the `auth` cookie from an `opencode.ai` browser session and the workspace ID shown in the dashboard URL.
+
+Provide them in one of these ways (highest priority first):
+
+1. Environment variables:
+
+   ```powershell
+   setx OPENCODE_GO_WORKSPACE_ID "wrk_01..."
+   setx OPENCODE_GO_AUTH_COOKIE "eyJhbGciOi..."
+   ```
+
+2. A config file at any of these paths (the first one that exists is used):
+
+   - `%APPDATA%\opencode-go\config.json` (Windows-friendly default)
+   - `%XDG_CONFIG_HOME%\opencode-bar\opencode-go.json`
+   - `%XDG_CONFIG_HOME%\opencode-quota\opencode-go.json`
+   - `~\.config\opencode-bar\opencode-go.json`
+   - `~\.config\opencode-quota\opencode-go.json`
+   - `%OPENCODE_GO_CONFIG_FILE%` (override)
+
+   The file is JSON with these keys (aliases accepted: `workspaceId`/`workspaceID`/`workspace_id` and `authCookie`/`auth_cookie`/`cookie`):
+
+   ```json
+   {
+     "workspaceId": "wrk_01...",
+     "authCookie": "eyJhbGciOi..."
+   }
+   ```
+
+To grab the values: sign in to `https://opencode.ai/go` in your browser, copy the `auth` cookie (DevTools → Application → Cookies → `https://opencode.ai`), and copy the workspace ID from the URL (`/workspace/<wrk_id>/go`).
+
+**Fallback — local SQLite (no setup required):** if the dashboard credentials above are not configured, the monitor falls back to reading the local OpenCode SQLite database at `$OPENCODE_DB` (if set), then `%USERPROFILE%\.local\share\opencode\opencode.db`, then `%APPDATA%\opencode\opencode.db`. The database is opened in `SQLITE_OPEN_READ_ONLY` mode and never written to. This reflects only this machine's session costs, not your full Go subscription across devices, and the reset countdowns show 5h and 7d windows from the current poll time (since the local DB has no server-side reset signal).
+
 It works best if you want a simple "how close am I to the limit?" display that is always visible.

 ## How It Works
 
 The monitor:
 
-1. Finds your enabled model login credentials
-2. Reads your current usage from Anthropic, ChatGPT, and/or Google's Antigravity endpoints
+1. Finds your enabled model login credentials (or, for OpenCode Go, your dashboard session cookie and workspace ID, or the local database)
+2. Reads your current usage from Anthropic, ChatGPT, Google's Antigravity endpoints, the OpenCode Go dashboard, and/or the local OpenCode database
 3. Shows the result directly in the Windows taskbar
 4. Keeps the widget aligned with the selected taskbar and tray area
 5. Refreshes periodically in the background
