+name: vscode-dev-workbench
+description: Use when the user wants to run the vscode.dev server locally and exercise the VS Code workbench or Agents window in the integrated browser against the local `microsoft/vscode` sources. Covers starting the dev server, the `vscode-quality=dev` URL, browser-driven interaction patterns, and optionally wiring up a local mock agent host for the Agents window.
+---
+
+# Running vscode.dev Against Local VS Code Sources
+
+The `vscode-dev` repo is the `vscode.dev` server. When run locally with `?vscode-quality=dev`, it serves the VS Code web workbench (or Agents window at `/agents`) from the **sibling** `microsoft/vscode` checkout. This is the fastest way to validate web-only changes to the workbench without shipping an Insiders build.
+
+## Layout assumption
+
+`vscode-dev` and `vscode` must be sibling folders:
+
+```
+<workRoot>/
+  vscode/          # microsoft/vscode checkout
+  vscode-dev/      # microsoft/vscode-dev checkout
+```
+
+If your paths differ, check `server/` in `vscode-dev` for the source root resolution — the `/vscode-sources/*` route maps to `../vscode`.
+
+## Start the dev server
+
+```bash
+cd vscode-dev
+npm run dev   # runs watch + nodemon; serves https://127.0.0.1:3000
+```
+
+On first start you may see one crash like `Cannot find module './indexes'` — it's the watcher racing the first build. nodemon restarts automatically once `out/` finishes compiling.
+
+## URLs
+
+- `https://127.0.0.1:3000/?vscode-quality=dev` — main workbench, local dev sources
+- `https://127.0.0.1:3000/agents?vscode-quality=dev` — Agents window, local dev sources
+- `https://127.0.0.1:3000/?vscode-version=<commit>` — pinned production commit
+- Add `&vscode-log=trace` for verbose client logging
+
+## Interacting via the integrated browser
+
+Use `open_browser_page` and the standard browser tools.
+
+### Enter inserts a newline in the chat input
+
+The chat input is a Monaco editor — `page.keyboard.press('Enter')` inserts a newline. To send, click the **Send** button (`a[aria-label^="Send"]`) or use the send keybinding.
+
+### Hard-reloading after a rebuild
+
+The service worker caches client assets aggressively. A plain reload can still serve stale modules:
+
+```js
+await page.evaluate(async () => {
+  const regs = await navigator.serviceWorker?.getRegistrations() ?? [];
+  await Promise.all(regs.map(r => r.unregister()));
+  const keys = await caches?.keys() ?? [];
+  await Promise.all(keys.map(k => caches.delete(k)));
+});
+await page.reload({ waitUntil: 'domcontentloaded' });
+```
+
+### Simulating mobile (only when explicitly requested)
+
+The integrated browser panel clamps width, so `page.setViewportSize()` and CDP `setDeviceMetricsOverride` narrow the viewport only as far as the panel allows. User-Agent override and touch emulation work fine:
+
+```js
+const client = await page.context().newCDPSession(page);
+await client.send('Emulation.setUserAgentOverride', {
+  userAgent: 'Mozilla/5.0 (iPhone; CPU iPhone OS 17_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/17.0 Mobile/15E148 Safari/604.1',
+  platform: 'iPhone'
+});
+await client.send('Emulation.setTouchEmulationEnabled', { enabled: true, maxTouchPoints: 5 });
+await client.send('Emulation.setDeviceMetricsOverride', {
+  width: 393, height: 852, deviceScaleFactor: 3, mobile: true,
+  screenOrientation: { type: 'portraitPrimary', angle: 0 }
+});
+await page.reload();
+```
+
+For a true mobile viewport, drive a standalone Playwright script with `devices['iPhone 14 Pro']` instead of the integrated browser. If a mobile-responsive overlay intercepts pointer events during automation, fall back to `{ force: true }` on `click()`.
+
+## Known-noise console messages (ignore)
+
+- `Canceled: Canceled` at `clipboardService.js` — cancelled permission probes on hover.
+- `NotAllowedError: Failed to execute 'write' on 'Clipboard'` — web clipboard requires a user gesture.
+- `[WebTunnelAgentHost] Failed to list tunnels` — only fires when not signed in.
+- `The web worker extension host is started in a same-origin iframe!` — expected in dev.
+- `Unrecognized feature: 'local-network-access'` — dev manifest warning.
+- `[LEAKED DISPOSABLE]` stacks — GC-based tracker; only real if reproducible across reloads.
+
+## Troubleshooting
+
+| Symptom                                                   | Cause                                      | Fix                                                        |
+| --------------------------------------------------------- | ------------------------------------------ | ---------------------------------------------------------- |
+| `Cannot find module './indexes'` on first run             | nodemon started before TS compile finished | Wait; it auto-restarts                                     |
+| `Session not found: <uuid>` when sending chat             | Reopened a cloud/tunnel-backed session     | Start a fresh session (⌘N) in the Agents window            |
+| Workspace picker opens native dialog and hangs automation | `Select Folder…` needs a real file dialog  | Pick a workspace URL scheme instead, or skip in automation |
+| Stale UI after editing `vscode/` sources                  | Service worker cache                       | Unregister SWs + clear caches (snippet above)              |
+
+## Testing the Agents window against a local mock agent host
+
+`vscode-dev` supports a `?mock-agent-host=ws://…` URL parameter that short-circuits tunnel discovery and wires the Agents window to a raw WebSocket. Pair it with the mock agent host binary from `microsoft/vscode`:
+
+```bash
+cd vscode
+node out/vs/platform/agentHost/node/agentHostServerMain.js \
+  --enable-mock-agent --quiet --without-connection-token --port 8765
+# Listens on ws://localhost:8765
+```
+
+`--enable-mock-agent` registers the `ScriptedMockAgent` from `src/vs/platform/agentHost/test/node/mockAgent.ts` with one pre-existing session. Seed additional sessions via the `VSCODE_AGENT_HOST_MOCK_SEED_SESSIONS` env var, using a comma-separated list of session URIs (for example, `VSCODE_AGENT_HOST_MOCK_SEED_SESSIONS=mock://pre-1,mock://pre-2`). Scripted prompts include `hello`, `use-tool`, `error`, `permission`, `write-file`, `run-safe-command`, `slow`, `client-tool`, `subagent`, etc. (see `mockAgent.ts` for the full list).
+
+Then open:
+
+```
+https://127.0.0.1:3000/agents?vscode-quality=dev&mock-agent-host=ws://localhost:8765&vscode-log=trace
+```
+
+Expect these logs in order:
+
+- `[MockAgentHost] Using local mock agent host at ws://localhost:8765/`
+- `[WebTunnelAgentHost] Found 1 tunnel(s) with agent host support`
+- `[WebTunnelAgentHost] Connecting to tunnel 'mock-agent-host' (mock)`
+- `[WebTunnelAgentHost] Protocol handshake completed with tunnel:mock`
+- `[RemoteAgentHost] Registered agent mock from tunnel:mock as remote-tunnel__mock-mock`
+
+This bypasses GitHub auth and the `/agents/api/hosts` endpoint entirely, so it works offline. The fake tunnel on the `vscode-dev` side must advertise a `protocolvN` tag ≥ `TUNNEL_MIN_PROTOCOL_VERSION` in `src/vs/platform/agentHost/common/tunnelAgentHost.ts` (currently 5); otherwise `WebTunnelAgentHostService` filters it out and you'll see `Found 0 tunnel(s) with agent host support`.
