 # @opencode-ai/client

-Promise and Effect clients derived from OpenCode's authoritative Effect `HttpApi`, plus handwritten Node transports.
+Private generation target for clients derived directly from OpenCode's authoritative Effect `HttpApi`.

 ## Entrypoints

 - `@opencode-ai/client`: zero-Effect Promise client using `fetch`.
- `@opencode-ai/client/node`: Promise client plus Node-hosted browser attachments.
 - `@opencode-ai/client/effect`: rich Effect network client using an environment-provided `HttpClient`.

 The generated surface includes every standard HTTP group from Server's concrete API. The build compiler reads `@opencode-ai/server/api`; the generated Effect runtime imports a client-local projection built from Protocol, with a generation-equivalence test preventing transport drift. Custom transports such as the PTY WebSocket connection remain outside the generic HTTP client. Run `bun run generate` after changing the contract and `bun run check:generated` to detect committed-output drift.

 The Effect entrypoint uses canonical decoded values such as `Session.ID`, `Location.Ref`, and `Prompt`. These datatypes come from the lightweight `@opencode-ai/schema` package and are re-exported so callers depend only on the client surface. Protocol owns endpoint construction and middleware placement; Server supplies the concrete middleware keys used by the build-time API.

-The Promise root remains structural and has no Core, Effect, Schema, Protocol, or WebSocket runtime dependency. `/node` adds Effect, Schema, Protocol, and `ws`, but never Core or Server. `/effect` depends only on Effect, Schema, and Protocol and remains browser-bundle safe. Bundle-boundary tests enforce these import graphs.
-
-## Node browser attachments
-
-The Node client owns a Session-scoped browser registration, authenticated loopback proxy, and remote network tunnels. Chromium hosts supply a platform port; the SDK handles browser commands, accessibility snapshots, element references, and document generations.
-
-```ts
-import { BrowserDriver, OpenCode } from "@opencode-ai/client/node"
-
-const driver = BrowserDriver.chromium(async ({ proxy, signal }) => {
-  const view = await createChromiumView({ proxy, signal })
-  return {
-    resource: view,
-    state: () => view.state(),
-    subscribe: (listener) => view.subscribe(listener),
-    navigate: (url) => view.navigate(url),
-    back: () => view.back(),
-    forward: () => view.forward(),
-    reload: () => view.reload(),
-    stop: () => view.stop(),
-    send: (command) => view.sendCDP(command.method, command.params),
-    viewport: () => view.viewport(),
-    screenshot: (maxDimension) => view.capturePNG(maxDimension),
-    dispose: () => view.close(),
-  }
-})
-
-const client = OpenCode.make({
-  baseUrl: "https://opencode.example",
-  headers: { authorization: `Basic ${credentials}` },
-})
-const registration = await client.browser.register({ sessionID, open: () => showBrowserPane() })
-const attachment = await registration.attach({ driver })
-
-await attachment.resource.navigate("localhost:5173")
-await attachment.close()
-await registration.close()
-```
-
-A registration remains connected after its attachment closes, allowing the browser to reopen on demand. Attachments resolve after their Session lease is acknowledged; drivers should configure their resource before initiating proxied navigation. `BrowserDriver.define` supports custom browser implementations, and `BrowserDriverError` carries typed command failures.
+The Promise root remains structural and has no Core or Effect runtime dependency. `/effect` depends only on Effect, Schema, and Protocol and is browser-bundle safe. Bundle-boundary tests enforce both import graphs.
