-# OpenCode Browser
-
-opencode in the side panel of Chromium browsers (Chrome, Edge, Brave, Opera, Vivaldi, Chromium, Helium, Arc). Chat with the
-local opencode service next to any page, let the agent use real tabs, and extend sites with site scripts.
-
-- **Side panel chat** with the desktop app's session timeline, composer, and permission and question docks.
-- **Browser control:** the built-in `browser.*` tools drive the tabs the agent opens and the tabs you share,
-  with a visible agent cursor. Agent tabs are grouped as "opencode".
-- **Site scripts:** userscripts the extension injects itself (`chrome.userScripts`), installed from replies or
-  by the agent with your approval, toggled live per site.
-- **Browsing data:** history, bookmarks, top sites, and recently closed tabs, after you allow it per
-  conversation.
-
-## Install
-
-```sh
-npx opencode-browser-cli install   # registers the helper, adds Browser Control, copies the extension
-```
-
-The helper is the `opencode-browser-cli` npm package in `cli/` (`bun run build` there bundles it with this
-extension's build). It asks your installed opencode for the service with `opencode service start` and
-`opencode service get password`, so it works with any opencode release. `opencode browser install` does
-the same from the opencode CLI.
-
-1. Open the browser's extensions page, turn on **Developer mode**, choose **Load unpacked**, and select
-   the folder `install` prints (or `packages/browser-extension/dist` when building from source). The manifest key keeps the extension ID stable
-   (`afeafocngkodbmaipcngoamamfmekgfo`).
-2. For site scripts, choose **Details** on OpenCode Browser and turn on **Allow user scripts**.
-3. Click the toolbar icon, or press <kbd>⌘</kbd><kbd>⇧</kbd><kbd>.</kbd>, to open the panel.
-
-`opencode browser install` registers the `ai.opencode.browser` native messaging host for every
-installed Chromium browser on macOS and Linux (a manifest in each browser's `NativeMessagingHosts`
-directory) and on Windows (per-user registry keys), matching the browsers ChatGPT's extension supports. The host is the opencode CLI itself (`opencode browser host`): it starts the
-background service if needed and returns its URL and password, so the panel connects without
-configuration. The extension also hands the host its opencode plugin (`plugin/opencode-browser.ts`, the
-`site_scripts` and `browsing` tools), which is written to `~/.config/opencode/plugins/opencode-browser.ts`
-whenever it changes, so the plugin always matches the installed extension. Without the host, the panel
-offers a manual URL and password form. `opencode browser status` and `opencode browser uninstall`
-check and remove the registration.
-
-## How it connects
-
-| Piece | Talks to | Over |
-| --- | --- | --- |
-| Side panel (`src/sidepanel`) | opencode service | `@opencode/client` HTTP and the event stream |
-| Side panel | background worker | one `chrome.runtime` port (`src/shared/protocol.ts`) |
-| Background (`src/background`) | `opencode.browser` plugin | `experimental.browser` RPC, attach v4, per session |
-| Background | tabs | `chrome.debugger` (CDP), `chrome.tabs`, `chrome.userScripts` |
-| Background | `opencode-browser` plugin (`plugin/`) | `opencode-browser.relay` RPC, while a panel is open |
-
-The background implements the same browser contract as the desktop pane
-(`packages/gui-extensions/src/browser`): the server plugin owns tools and permissions, the extension owns
-tabs and runs commands. Page operations, diagnostics, and profiling are ported from that package; keep them
-in step. Showing a session in the panel attaches its browser, which replaces another client's attachment for
-that session.
-
-Not available from an extension: heap snapshots (Chrome does not expose `HeapProfiler` to extensions) and
-Lighthouse. CPU profiles are rebuilt from the v8 sampling profiler's trace events.
-
-## Development
-
-```sh
-bun run dev       # rebuilds dist/ on change; reload the extension to pick it up
-bun typecheck
-```
-
-The plugin file must stay self-contained (type-only imports): it is copied into opencode as-is.
