 ## Debugging
 
-- To test the opencode app, use the playwright MCP server, the app is already

 - NEVER try to restart the app, or the server process, EVER.
 
+## Local Dev

+- `opencode dev web` proxies `https://app.opencode.ai`, so local UI/CSS changes will not show there.
+- For local UI changes, run the backend and app dev servers separately.
+- Backend (from `packages/opencode`): `bun run --conditions=browser ./src/index.ts serve --port 4096`
+- App (from `packages/app`): `bun dev -- --port 4444`
+- Open `http://localhost:4444` to verify UI changes (it targets the backend at `http://localhost:4096`).

 ## SolidJS

 ## Tool Calling

+## Browser Automation
+
+Use `agent-browser` for web automation. Run `agent-browser --help` for all commands.
+
+Core workflow:
+
+1. `agent-browser open <url>` - Navigate to page
+2. `agent-browser snapshot -i` - Get interactive elements with refs (@e1, @e2)
+3. `agent-browser click @e1` / `fill @e2 "text"` - Interact using refs
+4. Re-snapshot after page changes

 ## E2E Testing
 
-The Playwright runner expects the app already running at `http://localhost:3000`.
+Playwright starts the Vite dev server automatically via `webServer`, and UI tests need an opencode backend (defaults to `localhost:4096`).
+Use the local runner to create a temp sandbox, seed data, and run the tests.
 
 ```bash
-bun add -D @playwright/test
 bunx playwright install
-bun run test:e2e
+bun run test:e2e:local
+bun run test:e2e:local -- --grep "settings"
 ```
 
 Environment options:
 
-- `PLAYWRIGHT_BASE_URL` (default: `http://localhost:3000`)
-- `PLAYWRIGHT_PORT` (default: `3000`)
+- `PLAYWRIGHT_SERVER_HOST` / `PLAYWRIGHT_SERVER_PORT` (backend address, default: `localhost:4096`)
+- `PLAYWRIGHT_PORT` (Vite dev server port, default: `3000`)
+- `PLAYWRIGHT_BASE_URL` (override base URL, default: `http://localhost:<PLAYWRIGHT_PORT>`)

+
+## Test Structure
+
+All tests live in `packages/app/e2e/`:
+
+```
+e2e/
+├── fixtures.ts       # Test fixtures (test, expect, gotoSession, sdk)
+├── actions.ts        # Reusable action helpers
+├── selectors.ts      # DOM selectors
+├── utils.ts          # Utilities (serverUrl, modKey, path helpers)
+└── [feature]/
+    └── *.spec.ts     # Test files
+```
+
+## Test Patterns
+
+### Basic Test Structure
+
+```typescript
+import { test, expect } from "../fixtures"
+import { promptSelector } from "../selectors"
+import { withSession } from "../actions"
+
+test("test description", async ({ page, sdk, gotoSession }) => {
+  await gotoSession() // or gotoSession(sessionID)
+
+  // Your test code
+  await expect(page.locator(promptSelector)).toBeVisible()
+})
+```
+
+### Using Fixtures
+
+- `page` - Playwright page
+- `sdk` - OpenCode SDK client for API calls
+- `gotoSession(sessionID?)` - Navigate to session
+
+### Helper Functions
+
+**Actions** (`actions.ts`):
+
+- `openPalette(page)` - Open command palette
+- `openSettings(page)` - Open settings dialog
+- `closeDialog(page, dialog)` - Close any dialog
+- `openSidebar(page)` / `closeSidebar(page)` - Toggle sidebar
+- `withSession(sdk, title, callback)` - Create temp session
+- `clickListItem(container, filter)` - Click list item by key/text
+
+**Selectors** (`selectors.ts`):
+
+- `promptSelector` - Prompt input
+- `terminalSelector` - Terminal panel
+- `sessionItemSelector(id)` - Session in sidebar
+- `listItemSelector` - Generic list items
+
+**Utils** (`utils.ts`):
+
+- `modKey` - Meta (Mac) or Control (Linux/Win)
+- `serverUrl` - Backend server URL
+- `sessionPath(dir, id?)` - Build session URL
+
+## Code Style Guidelines
+
+### Imports
+
+Always import from `../fixtures`, not `@playwright/test`:
+
+```typescript
+// ✅ Good
+import { test, expect } from "../fixtures"
+
+// ❌ Bad
+import { test, expect } from "@playwright/test"
+```
+
+### Naming Conventions
+
+- Test files: `feature-name.spec.ts`
+- Test names: lowercase, descriptive: `"sidebar can be toggled"`
+- Variables: camelCase
+- Constants: SCREAMING_SNAKE_CASE
+
+### Error Handling
+
+Tests should clean up after themselves:
+
+```typescript
+test("test with cleanup", async ({ page, sdk, gotoSession }) => {
+  await withSession(sdk, "test session", async (session) => {
+    await gotoSession(session.id)
+    // Test code...
+  }) // Auto-deletes session
+})
+```
+
+### Timeouts
+
+Default: 60s per test, 10s per assertion. Override when needed:
+
+```typescript
+test.setTimeout(120_000) // For long LLM operations
+test("slow test", async () => {
+  await expect.poll(() => check(), { timeout: 90_000 }).toBe(true)
+})
+```
+
+### Selectors
+
+Use `data-component`, `data-action`, or semantic roles:
+
+```typescript
+// ✅ Good
+await page.locator('[data-component="prompt-input"]').click()
+await page.getByRole("button", { name: "Open settings" }).click()
+
+// ❌ Bad
+await page.locator(".css-class-name").click()
+await page.locator("#id-name").click()
+```
+
+### Keyboard Shortcuts
+
+Use `modKey` for cross-platform compatibility:
+
+```typescript
+import { modKey } from "../utils"
+
+await page.keyboard.press(`${modKey}+B`) // Toggle sidebar
+await page.keyboard.press(`${modKey}+Comma`) // Open settings
+```
+
+## Writing New Tests
+
+1. Choose appropriate folder or create new one
+2. Import from `../fixtures`
+3. Use helper functions from `../actions` and `../selectors`
+4. Clean up any created resources
+5. Use specific selectors (avoid CSS classes)
+6. Test one feature per test file
+
+## Local Development
+
+For UI debugging, use:
+
+```bash
+bun test:e2e:ui
+```
+
+This opens Playwright's interactive UI for step-through debugging.
