-# Experimental Browser Plugin
-
-The server-side browser tool lives alongside the other built-in plugins. Its
-implementation uses only the public plugin API, public schemas, and Effect. The
-shared RPC contract is `@opencode-ai/schema/browser`; desktop clients do not import Core.
-
-Disable it through normal plugin configuration:
-
-```jsonc
-{
-  "plugins": ["-opencode.browser"],
-}
-```
-
-The desktop implementation connects with `client.rpc(Browser.Definition)` at the
-session's location. Subscribe to server events before calling `attach`; wait for
-`server.connected`, then the matching `attached` control event. The `attach` call
-stays pending for the attachment lifetime. Abort it when its event stream ends or
-the desktop owner closes. Completing the attachment also ends that event consumer.
-
-- `attach` holds one browser attachment per session until cancellation, plugin
-  unload, session deletion, or session movement.
-- `state` reports the current page, or `null` when no page is open.
-- `result` completes a command with its request ID and outcome.
-- `control` events carry attachment confirmation, commands, and cancellation.
-
-Control events use OpenCode's existing authenticated, server-wide event feed.
-Consumers filter by `connectionID`; this identifier is correlation, not private
-event delivery. State and results use RPC calls rather than broadcast events.
-
-The plugin requests normal agent permissions before acting on a URL. Browser
-content is untrusted. Pages use the desktop's network, with no server-side tunnel.
-The desktop owns Chromium, page isolation, and native controls.

 Built-ins, plugins, and MCP install tools through `Tool.Service.transform`, adding complete tool objects to the draft. A tool may provide a namespace, which flattens direct model names to `<namespace>_<tool>`, and defaults into CodeMode (`codemode` defaults true; `codemode: false` keeps the tool on the provider's native tool list).
 
-Namespace descriptions are registered once through `draft.namespace(...)`. Tool options continue to reference the namespace by string name; an unregistered namespace remains valid and simply has no namespace description.
-
 The service uses shared `State` to replay synchronous transforms in registration order against a fresh draft. `Tool.Service.reload()` rebuilds from captured source data without changing registration precedence. Registrations are scoped and return a real, idempotent `dispose` Effect:
 
 - The latest valid active registration for the same effective name wins.
