# Browser Plugin
The browser feature owns its tools, context hooks, and live
attachment state here. Generic agent, session, and tool services contain no
browser policy.
- `index.ts` registers tools and lifecycle hooks through the existing plugin
context. Everything belongs to `opencode.browser`.
- `host.ts` is an instance-scoped bridge for the plugin and server transport. It
has no Session store or Bus dependencies. Plugin activation enables it; plugin
unload revokes registrations and pending requests.
- `tools.ts` owns browser commands, leaf permission checks, and untrusted output
rendering. Permissions follow the existing agent rules and permission service,
like other built-in tools. The plugin does not add or change agent defaults.
The server adapter owns WebSocket and TCP I/O. It validates the Session and selects
its instance before accessing the bridge. Session deletion or movement releases
the old attachment through the plugin's event subscription.
Disable the feature with `plugins: ["-opencode.browser"]`. There are no legacy
plugin IDs, compatibility entrypoints, or process-global browser registrations.
