-# Experimental Browser Plugin
-
-`@opencode-ai/plugin-browser` implements the server-side browser tool using only
-the public plugin API, public schemas, and Effect. Core registers it as a built-in
-plugin; the package does not depend on Core or Server. 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.
-
-Per-URL permission checks are deferred to the final permission layer (#46530).
-Until that layer lands, browser actions do not enforce URL-specific ask or deny
-rules. Attachment ownership, page validation, and cancellation remain enforced.
-
-Browser content is untrusted. Pages use the desktop's network, with no server-side
-tunnel. The desktop owns Chromium, page isolation, and native controls.

 The Worker has `workers_dev` and preview URLs disabled so the custom hostname is its only public entry point.
 
-## Request logging
-
-Every request reaching the Worker emits an unsampled event at request start to the shared production
-Cloudflare lake stream through the `EVENTS` Pipelines binding. Events use
-`source: "update"`, `type: "request"`, an ISO `timestamp`, and a `payload` containing
-the method, path, `useragent`, `ip` (from Cloudflare's `CF-Connecting-IP` header),
-country, and Cloudflare colo. Query strings, request bodies, cookies, and authorization
-headers are not included. Response status and duration are not recorded.
-
-Delivery runs in `waitUntil` without delaying the response. Delivery failures are
-logged but do not fail requests or retry; this is not lossless audit logging.
-Requests blocked before reaching the Worker are not recorded.
-
-The stream ID in `wrangler.jsonc` comes from the `lake.stream` output of the
-`anomalyco/platform/production` Pulumi stack. Update the binding if that stream is
-replaced. The stream is shared across release channels because the update service
-has a single public deployment.
-
-## Publishing
-
 GitHub Actions publishes artifacts through `POST /api/publish` using a short-lived OIDC token with audience `https://update.opencode.ai`. The Worker accepts only tokens signed by GitHub for repository ID `975734319`, owner ID `66570915`, and `.github/workflows/publish.yml` on configured publishing refs.
