-# Browser plugin
-
-`@opencode-ai/plugin-browser` exposes the desktop browser through Code Mode.
-The server owns tools, invocation scope, and permissions; the desktop owns tabs,
-CDP, captured traffic, evaluations, and capture files. Core only registers the
-plugin. Neither endpoint imports the other's implementation.
-
-```js
-const tab = await tools.browser.tabs.open({ url: "https://example.com" })
-return await tools.browser.snapshot({ tabID: tab.id })
-```
-
-All page operations require a `tabID` returned by `browser.tabs.open/list`.
-Focus selects the visible Review tab, not an implicit command target. Discover
-current signatures with `search({ namespace: "browser" })`.
-Screenshots require a focused, visible tab; call `browser.tabs.focus` first.
-
-## Tools
-
-- Tabs: `tabs.list`, `tabs.open`, `tabs.focus`, `tabs.close`.
-- Navigation: `navigate`, `back`, `forward`, `reload`, `stop`, `frames`.
-- Observation: `snapshot`, `find`, `evaluate`, `wait`, `screenshot`.
-- Input: `click`, `hover`, `drag`, `fill`, `fill_form`, `select`, `check`, `press`, `scroll`, `dialog`.
-- Files: `files.upload`, `files.drop`, `files.list`, `files.get`.
-- Diagnostics: `console`, `network.list`, `network.get`.
-- Performance: `trace.start`, `trace.stop`, `trace.analyze`, `cpu.start`, `cpu.stop`, `cpu.analyze`.
-- Memory: `heap.snapshot`, `heap.summary`, `heap.query`, `heap.object`, `heap.compare`.
-- Audits: `lighthouse` (accessibility, SEO, best practices).
-
-The source of truth for inputs, descriptions, and outputs is
-`Browser.Operations` in `@opencode-ai/plugin-browser/rpc`.
-
-The plugin entrypoint only composes its two owners: `connection.ts` manages
-desktop attachments and pending RPC requests; `tools.ts` runs the tool workflow.
-Server-local file IO stays in `files.ts`. The public `rpc.ts` entrypoint remains
-pure and does not load any of these runtime modules.
-
-## Tests
-
-Run `bun test` and `bun typecheck` from this package for its contract checks.
-Native browser coverage lives in `packages/desktop/test/browser-native.test.ts`.
-
-## RPC
-
-The plugin-owned contract is `@opencode-ai/plugin-browser/rpc`. This entrypoint
-contains only schemas and descriptions; it does not load the server plugin or
-filesystem code. The desktop subscribes
-to control events before starting `attach` with `version: 4`. The attachment call
-stays pending for its lifetime. A matching `attached` event is the readiness barrier.
-
-- `state` publishes the authoritative tab inventory.
-- `control` announces a request ID or cancellation; it never broadcasts arguments,
-  script source, file bytes, or browser results on the server-wide event feed.
-- `command` retrieves the pending request through authenticated RPC.
-- `result` completes it. The plugin validates the selected operation's output.
-- Inspection commands return only target/source metadata. Execution checks that
-  the approved target has not changed while permission was pending.
-- `attach` returns `replaced` when another desktop takes ownership. That is not
-  a retryable disconnect; the old desktop must not reclaim the session automatically.
-
-The connection ID is correlation, not separate client authentication. Requests
-are bound to their attachment and tab. Disconnect, replacement, session movement,
-and unload fail outstanding work. Calls are not replayed automatically: a lost
-response does not prove that a click or evaluation never happened.
-
-## Files and remote servers
-
-Upload paths are **server-local**. File bytes cross RPC and the desktop writes its
-own temporary copy. Captures/downloads travel back as bounded bytes and are saved
-to server-local temporary files. Returned `files[].path` values refer to that
-server; bytes are not included in the model's structured output. Images are also
-attached for the model to inspect. Temporary exports are not deleted on plugin
-reload, so a returned path remains usable; they follow the host's temporary-file
-lifetime.
-
-Each transfer is limited to 5 MiB total. There is no shared filesystem assumption,
-resumable file-transfer service or object store. Browsing uses the connected
-server's network: `localhost:8000` reaches that server's port 8000, while Chromium
-and page JavaScript still run on the desktop. Dev-server ports need not be public.
-
-`tunnel.open/read/write/close` relay bounded TCP chunks through the existing
-authenticated plugin RPC route. The desktop-only `/proxy` entrypoint adapts
-Chromium's HTTP/CONNECT proxy traffic, including WebSockets, to those methods.
-Network bytes never go onto the global event stream. Attachment closure releases
-the sockets; failed writes are not replayed and there is no direct-network fallback.
-
-Remote endpoints can use HTTPS and the existing server credentials. A reverse
-proxy must allow long-lived event and attachment requests; the attachment RPC
-stays open rather than sending response-body heartbeats.
-
-Lighthouse audits use snapshot mode without changing device emulation or adding
-an embedded report screenshot; use `browser.screenshot` for images. Trace exports
-contain the target renderer process, not the whole desktop application. A tab
-process change or trace-buffer loss is reported as an incomplete capture. Heap
-summaries report shallow size, not computed retained size, and do not prove leaks.
-
-All page-derived data is untrusted, including structured outputs. Schema
-validation does not make page text an instruction or grant it authority.
-
-## Recovering from errors
-
-Errors name the failed operation and the next supported action. Refresh tab IDs
-with `browser.tabs.list`, element refs with `browser.snapshot`, and frame IDs with
-`browser.frames`. File and network request IDs must come from the same tab's
-current listing. Trace, CPU, and heap files are not interchangeable.
-
-A timeout, cancellation, or disconnection does not prove the action never ran.
-Inspect the tab and completed files before repeating clicks, uploads, submissions,
-or evaluations. Do not retry a permission denial through another tool or weaken
-browser security to work around a TLS or unsupported-operation error.
-
-File errors distinguish server-local upload paths from desktop capture files.
-Pending/failed downloads and unavailable response bodies are not empty files.
-Oversized output requires a smaller request or capture, not an identical retry.
-
-Per-URL and server-file permission checks belong to the final permission layer
-(#46530). This base plugin layer intentionally does not enforce those rules.
-
-Disable through normal configuration:
