88-96: Translate untranslated English keys in fa-IR locale file to Persian.

The browser object in the fa-IR (Persian) locale contains four keys with English values instead of Persian translations:

• back: "Back"
• forward: "Forward"
• reload: "Reload"
• addressPlaceholder: "Enter a URL"

All other locale files (zh-CN, en-US, ko-KR, ru-RU, zh-HK, fr-FR) have proper translations for these keys. The remaining keys in fa-IR (enterUrlDescription, enterUrlToStart, name) are correctly translated to Persian. Translate the four keys to maintain consistency with other locales and provide a proper localized experience for Persian-speaking users.

301-303: Serializing raw image data may bloat the context.

block.image_data?.data could contain large base64-encoded images. Including this in the context string may cause token limit issues when sent to the LLM for query rewriting.

89-92: Translate browser navigation keys to Danish.

Lines 89-92 contain English text ("Back", "Forward", "Reload", "Enter a URL") that should be translated to Danish for the da-DK locale.

Suggested Danish translations:

• "Back" → "Tilbage"
• "Forward" → "Frem"
• "Reload" → "Genindlæs"
• "Enter a URL" → "Indtast en URL"

As per coding guidelines, all user-facing strings must be properly localized for each language.

89-92: Mixed language in Hebrew translation file

Lines 89-92 contain English text instead of Hebrew translations. This is inconsistent with the rest of the Hebrew locale file and will display English UI elements to Hebrew users.

🔎 Apply this diff to use Hebrew translations:

-    "back": "Back",
-    "forward": "Forward",
-    "reload": "Reload",
-    "addressPlaceholder": "Enter a URL",
+    "back": "חזור",
+    "forward": "קדימה",
+    "reload": "רענן",
+    "addressPlaceholder": "הזן כתובת URL",

Based on coding guidelines: Maintain consistent key-value structure across all language translation files.

src/main/presenter/browser/tools/types.ts-32-48 (1)

32-48: Naming conflict between local and shared BrowserToolDefinition types.

Two interfaces with the same name exist in different locations:

• src/shared/types/browser.ts: Uses inputSchema: Record<string, unknown> and requiresVision
• src/main/presenter/browser/tools/types.ts: Uses schema: ZodTypeAny, handler, and annotations

These serve different purposes (shared contracts vs. internal Zod-based tool definitions), but the identical naming creates confusion for maintainability. The BrowserContextBuilder.summarizeTools() method expects the shared version, though it's currently unused.

Rename the local type to ZodBrowserToolDefinition or InternalBrowserToolDefinition to clarify its scope and purpose.

144-154: Consider escaping selector strings to prevent script breakage.

If a selector value contains characters like backticks, ${, or the placeholder pattern itself, the generated script could break or behave unexpectedly.

603-620: Consider simplifying the scroll timing logic.

The nested setTimeout with nextTick pattern (lines 608-615) may be overcomplicated. The nextTick callback already waits for the next DOM update cycle, so wrapping it in a 300ms setTimeout might be unnecessary.

Consider testing if this simpler approach works:

🔎 Suggested simplification

     await yoBrowserPresenter.createTab('about:blank')
-    setTimeout(() => {
-      nextTick(() => {
-        if (endOfTabs.value) {
-          console.log('newTabButton', endOfTabs.value)
-          endOfTabs.value.scrollIntoView({ behavior: 'smooth', block: 'center' })
-        }
-      })
-    }, 300)
+    await nextTick()
+    if (endOfTabs.value) {
+      endOfTabs.value.scrollIntoView({ behavior: 'smooth', block: 'center' })

44-49: Consider more specific typing for inputSchema.

The inputSchema is typed as Record<string, unknown>, which is safe but provides minimal type information. If the project uses JSON Schema or similar, consider using a more specific type (e.g., JSONSchema7 from @types/json-schema).

This is optional since the current typing is not incorrect, just less helpful for consumers.

894-894: Consider removing commented-out debug code instead of leaving it.

Commented-out code tends to accumulate and become noise. If this debug logging is no longer needed, it's cleaner to remove it entirely. It can always be restored from version control if needed later.

🔎 Apply this diff to remove the dead code:

-      // console.log('chunk.candidates', JSON.stringify(chunk.candidates, null, 2))

src/main/presenter/browser/tools/screenshot.ts (1)

20-45: Consider adding error handling for screenshot capture.

While the code correctly handles the missing tab case, the tab.takeScreenshot() call at lines 31-35 lacks try-catch error handling. If the screenshot operation fails (e.g., due to DOM issues, CDP errors, or memory constraints), the error will propagate uncaught.

As per coding guidelines: "Always use try-catch to handle possible errors in TypeScript code" and "Provide meaningful error messages when catching errors."

🔎 Consider applying this error handling pattern:

       const tab = await context.getTab(tabId)
       if (!tab) {
         return {

27-37: Add error handling to loadState for presenter calls.

The loadState function calls yoBrowserPresenter.listTabs() and yoBrowserPresenter.isVisible() without try-catch. If either call fails, the error will propagate unhandled. Per coding guidelines, async operations should handle errors appropriately.

Suggested fix

 const loadState = async () => {
+  try {
     const [list, visible] = await Promise.all([
       yoBrowserPresenter.listTabs(),
       yoBrowserPresenter.isVisible()
     ])
     if (Array.isArray(list)) {
       tabs.value = list
       activeTabId.value = list.find((item) => item.isActive)?.id ?? null
     }
     isVisible.value = Boolean(visible)
+  } catch (error) {
+    console.error('[YoBrowser Store] Failed to load state', error)
+  }
 }

81-95: Add error handling to show, hide, and toggleVisibility actions.

These async actions call presenter methods without try-catch blocks. Failures could leave the UI in an inconsistent state.

Suggested fix for show/hide

 const show = async () => {
+  try {
     await yoBrowserPresenter.show()
     await loadState()
+  } catch (error) {
+    console.error('[YoBrowser Store] Failed to show browser', error)
+  }
 }

 const hide = async () => {
+  try {
     await yoBrowserPresenter.hide()
     await loadState()
+  } catch (error) {
+    console.error('[YoBrowser Store] Failed to hide browser', error)
+  }
 }

 const toggleVisibility = async (): Promise<boolean> => {
+  try {
     const visible = await yoBrowserPresenter.toggleVisibility()
     isVisible.value = Boolean(visible)
     return isVisible.value
+  } catch (error) {
+    console.error('[YoBrowser Store] Failed to toggle visibility', error)
+    return isVisible.value
+  }
 }

src/main/presenter/browser/ScreenshotManager.ts (1)

25-27: Consider using structured logging instead of console.error.

Per coding guidelines, main process code should use structured logging with logger.error() methods. The current implementation uses console.error, which may not integrate with the application's logging infrastructure.

src/main/presenter/llmProviderPresenter/providers/openAICompatibleProvider.ts (1)

990-990: Consider removing or enabling the debug log.

Commented-out debug logs can clutter the codebase. Consider either removing it or enabling it with a proper log level (e.g., logger.debug()).

src/renderer/shell/components/BrowserToolbar.vue (1)

127-155: Consider awaiting refreshNavigationState for better timing.

The refreshNavigationState() calls are not awaited, which means they might execute while the navigation action is still processing. This could result in stale state.

Suggested fix

 const goBack = async () => {
   if (!activeBrowserTabId.value) return
   try {
     await yoBrowserPresenter.goBack(activeBrowserTabId.value)
+    await refreshNavigationState()
   } catch (error) {
     console.error('Failed to go back', error)
   }
-  refreshNavigationState()
 }

Apply similar pattern to goForward and reload.

src/main/presenter/browser/tools/content.ts (1)

78-78: Consider adding timeout for waitForNetworkIdle.

The browser_get_markdown tool calls waitForNetworkIdle() without a timeout. On slow or perpetually-loading pages, this could block indefinitely.

🔎 Suggested fix:

-        await tab.waitForNetworkIdle()
+        await tab.waitForNetworkIdle({ timeout: 10000 })

src/main/presenter/windowPresenter/index.ts (1)

738-739: Consider extracting the type assertion to a variable for clarity.

The presenter.tabPresenter as TabPresenter cast is used multiple times throughout this file. While functionally correct, a local reference could improve readability.

🔎 Optional improvement:

     this.windows.set(windowId, shellWindow) // 将窗口实例存入 Map
-    ;(presenter.tabPresenter as TabPresenter).setWindowType(windowId, windowType)
+    const tabPresenterInstance = presenter.tabPresenter as TabPresenter
+    tabPresenterInstance.setWindowType(windowId, windowType)

This pattern is already used elsewhere in the file (e.g., line 437), so applying it here would improve consistency.

src/main/presenter/browser/BrowserToolManager.ts (1)

32-46: Consider stronger typing for args parameter and extra fallback.

Using any for args and casting extra to any reduces type safety. Since BrowserToolDefinition handlers may have specific argument schemas (via Zod), consider using unknown for args and handling the extra parameter more explicitly.

🔎 Suggested improvement

  async executeTool(
    toolName: string,
-   args: any,
+   args: unknown,
    extra?: RequestHandlerExtra<Request, Notification>
  ) {
    const tool = this.tools.find((t) => t.name === toolName)
    if (!tool) {
      return {
        content: [{ type: 'text', text: `Unknown tool: ${toolName}` }],
        isError: true
      }
    }

    const context = this.createContext()
-   return await tool.handler(args, context, extra || ({} as any))
+   return await tool.handler(args, context, extra)
  }

src/main/presenter/browser/DownloadManager.ts (2)

41-48: Consider removing the 'updated' listener when download completes.

The updated event listener on line 41 is never explicitly removed. While Electron's DownloadItem is typically garbage-collected after the download completes, explicitly removing the listener in the done handler would be cleaner and prevent potential issues if the DownloadItem reference is retained.

🔎 Suggested improvement

+       const onUpdated = (_updateEvent, state) => {
+         const existing = this.downloads.get(id)
+         if (!existing) return
+         existing.receivedBytes = item.getReceivedBytes()
+         existing.totalBytes = item.getTotalBytes()
+         existing.status = state === 'interrupted' ? 'failed' : 'in-progress'
+         this.downloads.set(id, { ...existing })
+       }
+
-       item.on('updated', (_updateEvent, state) => {
-         const existing = this.downloads.get(id)
-         if (!existing) return
-         existing.receivedBytes = item.getReceivedBytes()
-         existing.totalBytes = item.getTotalBytes()
-         existing.status = state === 'interrupted' ? 'failed' : 'in-progress'
-         this.downloads.set(id, { ...existing })
-       })
+       item.on('updated', onUpdated)

        item.once('done', (_doneEvent, state) => {
+         item.removeListener('updated', onUpdated)
          const existing = this.downloads.get(id)
          // ... rest of done handler

5-6: Downloads map grows indefinitely without cleanup.

The downloads Map accumulates entries for every download without any cleanup mechanism. For long-running sessions with many downloads, this could lead to memory growth. Consider adding a maximum size limit or TTL-based cleanup for completed/failed downloads.

src/renderer/shell/App.vue (1)

43-47: Simplify boolean expression.

The Boolean() wrapper is unnecessary since the expression already evaluates to a boolean. The negation and && operators ensure a boolean result.

🔎 Suggested simplification

 const isWebTabActive = computed(() => {
   const tab = activeTab.value
   if (!tab) return false
-  return Boolean(!tab.url?.startsWith('local://') && tab.browserTabId)
+  return !tab.url?.startsWith('local://') && !!tab.browserTabId
 })

src/main/presenter/browser/CDPManager.ts (1)

5-14: Consider adding error handling for debugger attachment.

While isAttached() is checked before attach(), the attach() and sendCommand() calls can still throw. Consider wrapping in try-catch to provide more context on failures, per coding guidelines.

🔎 Suggested improvement

  async createSession(webContents: WebContents): Promise<Debugger> {
    const session = webContents.debugger
-   if (!session.isAttached()) {
-     session.attach('1.3')
-     await session.sendCommand('Page.enable')
-     await session.sendCommand('DOM.enable')
-     await session.sendCommand('Runtime.enable')
+   try {
+     if (!session.isAttached()) {
+       session.attach('1.3')
+       await session.sendCommand('Page.enable')
+       await session.sendCommand('DOM.enable')
+       await session.sendCommand('Runtime.enable')
+     }
+     return session
+   } catch (error) {
+     const message = error instanceof Error ? error.message : String(error)
+     throw new Error(`Failed to create CDP session: ${message}`)
    }
-   return session
  }

src/main/presenter/browser/tools/download.ts (1)

23-51: Handler ignores parsed arguments.

The browser_get_download_list handler doesn't use the args or context parameters. The tabId argument from the schema is never utilized. Consider adding a TODO comment to clarify this is intentional for the stub, or remove unused parameters from the handler signature.

-      handler: async () => {
+      handler: async (_args, _context) => {
         // Note: Download list functionality needs to be implemented in YoBrowserPresenter
-        // For now, return empty list
+        // For now, return empty list. TODO: Use tabId from args when implementing

src/main/presenter/llmProviderPresenter/managers/agentLoopHandler.ts (1)

186-198: Duplicate browser tool definition fetching logic.

This code block duplicates the logic in the getAllToolDefinitions callback (lines 30-48). The tool definitions are fetched twice per iteration: once here for passing to coreStream, and again in ToolCallProcessor via the callback.

Consider consolidating by storing the fetched definitions in a variable or refactoring getAllToolDefinitions to be reusable.

🔎 One approach - extract to a shared method:

+  private async fetchAllToolDefinitions(enabledMcpTools?: string[]): Promise<MCPToolDefinition[]> {
+    const defs: MCPToolDefinition[] = []
+    const mcpDefs = await presenter.mcpPresenter.getAllToolDefinitions(enabledMcpTools)
+    defs.push(...mcpDefs)
+
+    const hasBrowserWindow = await presenter.yoBrowserPresenter.hasWindow()
+    if (hasBrowserWindow) {
+      try {
+        const yoDefs = await presenter.yoBrowserPresenter.getToolDefinitions(
+          this.currentSupportsVision
+        )
+        defs.push(...yoDefs)
+      } catch (error) {
+        console.warn('[AgentLoop] Failed to load Yo Browser tool definitions', error)
+      }
+    }
+    return defs
+  }

Then use this.fetchAllToolDefinitions(enabledMcpTools) in both places.

src/main/presenter/browser/tools/types.ts (1)

36-37: Consider using generics instead of any for type safety.

The args: any parameter loses type information. Since schema is ZodTypeAny, you could infer the args type from it using Zod's inference utilities.

🔎 Suggested improvement:

+import type { z, ZodTypeAny } from 'zod'
+
-export interface BrowserToolDefinition {
+export interface BrowserToolDefinition<TSchema extends ZodTypeAny = ZodTypeAny> {
   name: string
   description: string
-  schema: ZodTypeAny
+  schema: TSchema
   handler: (
-    args: any,
+    args: z.infer<TSchema>,
     context: BrowserToolContext,
     extra: RequestHandlerExtra<Request, Notification>
   ) => Promise<ToolResult>

src/main/presenter/tabPresenter.ts (3)

55-67: Consider debouncing the view bounds update when chrome height changes.

When updateChromeHeight is called, it iterates over all tabs and updates their bounds synchronously. If this is called frequently (e.g., during animations), it could cause performance issues.

---

69-80: Missing error handling in async notification.

The notifyWindowTabsUpdate call is wrapped in .catch() but the error is only logged as a warning. The setTabBrowserId method is synchronous but triggers an async operation without proper error propagation to the caller.

🔎 Consider making this method async:

-  setTabBrowserId(tabId: number, browserTabId: string): void {
+  async setTabBrowserId(tabId: number, browserTabId: string): Promise<void> {
     const state = this.tabState.get(tabId)
     if (state) {
       state.browserTabId = browserTabId
       const windowId = this.tabWindowMap.get(tabId)
       if (windowId !== undefined) {
-        this.notifyWindowTabsUpdate(windowId).catch((error) => {
-          console.warn(`Failed to sync browser tab id for window ${windowId}:`, error)
-        })
+        await this.notifyWindowTabsUpdate(windowId)
       }
     }
   }

---

754-772: Magic numbers for topOffset should be documented or extracted as constants.

The hardcoded values 84 and 36 for browser vs chat window offsets are not immediately clear. Consider extracting these as named constants with documentation.

🔎 Suggested improvement:

+  // Layout constants
+  // Chat mode: AppBar = 36px (h-9)
+  // Browser mode: AppBar + BrowserToolbar = 36px + 48px = 84px (h-9 + h-12)
+  private static readonly CHAT_HEADER_HEIGHT = 36
+  private static readonly BROWSER_HEADER_HEIGHT = 84

   private updateViewBounds(window: BrowserWindow, view: WebContentsView): void {
     if (window.isDestroyed()) return
     const { width, height } = window.getContentBounds()

     const windowType = this.getWindowType(window.id)
-    const topOffset = windowType === 'browser' ? 84 : 36
+    const topOffset = windowType === 'browser' 
+      ? TabPresenter.BROWSER_HEADER_HEIGHT 
+      : TabPresenter.CHAT_HEADER_HEIGHT
     const viewHeight = Math.max(0, height - topOffset)

src/main/presenter/browser/BrowserTab.ts (2)

39-55: Consider re-throwing errors with context preservation.

The error handling logs the error but re-throws it without additional context. Consider wrapping with more context for debugging.

🔎 Suggested improvement:

     } catch (error) {
       this.status = BrowserTabStatus.Error
       console.error(`[YoBrowser][${this.tabId}] navigate failed:`, error)
-      throw error
+      throw new Error(`Navigation to ${url} failed: ${error instanceof Error ? error.message : String(error)}`)
     }

---

117-124: Screenshot size limit of 20000px is reasonable but consider documenting this constraint.

The 20000px limit prevents memory issues with extremely large pages, but this limitation should be documented in the method's JSDoc or interface.

src/main/presenter/browser/YoBrowserPresenter.ts (2)

187-205: Potential logic issue in navigateTab when tab is destroyed.

When the original tab is destroyed, a new tab is created with the URL. However, the method then checks if (!tab) after already having created with an ID, which could be confusing. Consider simplifying the flow.

🔎 Suggested simplification:

   async navigateTab(tabId: string, url: string, timeoutMs?: number): Promise<void> {
-    let tab = this.tabIdToBrowserTab.get(tabId)
-    if (!tab || tab.contents.isDestroyed()) {
+    const existingTab = this.tabIdToBrowserTab.get(tabId)
+    
+    if (!existingTab || existingTab.contents.isDestroyed()) {
       const created = await this.createTab(url)
       if (!created) {
         throw new Error('Failed to create tab for navigation')
       }
-      tab = this.tabIdToBrowserTab.get(created.id) ?? undefined
       this.activeTabId = created.id
+      this.emitTabNavigated(created.id, url)
+      return
     }
-    if (!tab) {
-      throw new Error(`Tab ${tabId} not found`)
-    }
-    if (tab.contents.isDestroyed()) {
-      throw new Error(`Tab ${tab.tabId} is destroyed`)
-    }
-    await tab.navigate(url, timeoutMs)
-    this.emitTabNavigated(tab.tabId, url)
+    
+    await existingTab.navigate(url, timeoutMs)
+    this.emitTabNavigated(existingTab.tabId, url)
   }

---

399-415: Silent catch in findReusableTab may hide URL parsing issues.

The empty catch blocks silently ignore URL parsing errors. While this is intentional for fallback behavior, consider logging at debug level for troubleshooting.

🔎 Suggested improvement:

   private findReusableTab(url: string): BrowserTab | null {
     if (!url) return this.findOldestTab()
     try {
       const targetHost = new URL(url).hostname
       const sameHost = Array.from(this.tabIdToBrowserTab.values()).find((tab) => {
         try {
           return new URL(tab.url).hostname === targetHost
         } catch {
+          // Tab URL is not a valid URL (e.g., about:blank)
           return false
         }
       })
       if (sameHost) return sameHost
     } catch {
-      // ignore parse errors
+      // Target URL is not a valid URL, fall back to oldest tab
     }
     return this.findOldestTab()
   }

95-129: Critical: Missing error handling in all tool handlers.

All four tool handlers (browser_get_text, browser_get_markdown, browser_read_links, browser_get_clickable_elements) lack try-catch blocks around async operations and Zod schema parsing. These operations can throw on:

• Validation failures (ContentArgsSchema.parse, etc.)
• Tab resolution failures (context.resolveTabId, context.getTab)
• Content extraction failures (tab.getInnerText, tab.getHtml, tab.getLinks, tab.getClickableElements)
• Network timeouts (tab.waitForNetworkIdle)
• HTML parsing errors (turndown.turndown)

Without error handling, exceptions will crash the handler and provide no user feedback. As per coding guidelines: always use try-catch, provide meaningful error messages, and use structured logging.

🔎 Apply this pattern to all four handlers:

       handler: async (args, context) => {
+        try {
           const parsed = ContentArgsSchema.parse(args)
           const tabId = await context.resolveTabId(parsed)
           const tab = await context.getTab(tabId)
           if (!tab) {
             return {
               content: [{ type: 'text', text: `Tab ${tabId} not found` }],
               isError: true
             }
           }

           const text = await tab.getInnerText(parsed.selector)
           const { slice, meta } = paginateText(text, parsed.offset, parsed.limit)

           const content: { type: 'text'; text: string }[] = []

           if (!slice && !meta) {
             content.push({ type: 'text', text: '(no text found)' })
           } else {
             if (meta) {
               content.push({
                 type: 'text',
                 text: `[pagination] ${meta}`
               })
             }
             if (slice) {
               content.push({
                 type: 'text',
                 text: slice
               })
             }
           }

           return { content }
+        } catch (error) {
+          // TODO: Import and use structured logger (e.g., logger.error)
+          console.error('[browser_get_text] Failed to extract text:', error)
+          const message = error instanceof Error ? error.message : String(error)
+          return {
+            content: [{ type: 'text', text: `Failed to extract text: ${message}` }],
+            isError: true
+          }
+        }
       },

7-7: Remove commented code or add explanation.

The commented screenshot tools import suggests incomplete functionality. According to coding guidelines, unused or commented-out code should be avoided.

If screenshot functionality is intentionally disabled or not yet implemented, add a TODO comment explaining the status. Otherwise, remove the commented line.

🔎 Consider one of these approaches:

Option 1: Add explanation if temporarily disabled

-// import { createScreenshotTools } from './tools/screenshot'
+// TODO: Screenshot tools temporarily disabled pending CDP screenshot implementation
+// import { createScreenshotTools } from './tools/screenshot'

Option 2: Remove if not needed

-// import { createScreenshotTools } from './tools/screenshot'

22-22: Consistent with line 7: Remove or document commented screenshot tools.

This commented line is consistent with the commented import at line 7. Apply the same resolution (add explanation or remove entirely).

28-30: Consider defensive copy for encapsulation.

Returning the internal tools array directly allows external code to mutate it. While tool definitions are typically read-only, returning a shallow copy would provide better encapsulation.

🔎 Optional: Return a defensive copy

  getToolDefinitions() {
-   return this.tools
+   return [...this.tools]
  }

Learning: Applies to src/main/presenter/llmProviderPresenter/index.ts : In `src/main/presenter/llmProviderPresenter/index.ts`, listen for standardized events yielded by `coreStream` and handle them accordingly: buffer text content (`currentContent`), handle `tool_call_start/chunk/end` events by collecting tool details and calling `presenter.mcpPresenter.callTool`, send frontend events via `eventBus` with tool call status, format tool results for the next LLM call, and set `needContinueConversation = true`

448-457: Document serialization limitations for the evaluate method.

The JSON.stringify approach (line 451-452) cannot handle circular references, functions, or certain object types. While this is a common pattern, documenting these limitations would help prevent misuse.

💡 Add JSDoc documentation:

+/**
+ * Evaluates a function in the browser context with the provided arguments.
+ * Note: Arguments must be JSON-serializable (no circular refs, functions, or symbols).
+ * @param fn - Function to evaluate in the browser context
+ * @param args - Arguments to pass (must be JSON-serializable)
+ * @returns The result of the function execution
+ */
 private async evaluate<T>(fn: (...args: any[]) => T, ...args: any[]): Promise<T> {

465-546: Consider improving type safety for event listeners.

The waitForLoad implementation is comprehensive with proper cleanup logic. However, the as any casts (lines 500, 538) suggest type mismatches with Electron's event signatures.

Consider typing the event handler to match Electron's signature:

onFailLoad: ((event: Electron.Event, errorCode: number, errorDescription: string, validatedURL: string, isMainFrame: boolean, frameProcessId: number, frameRoutingId: number) => void) | null = null

Or use a wrapper function to avoid the cast.

39-55: Consider adding URL validation in navigate().

The navigation methods properly manage status transitions and error handling. However, navigate() doesn't validate the URL format before attempting to load, which could result in unclear error messages for invalid URLs.

💡 Optional: Add URL validation:

 async navigate(url: string, timeoutMs?: number): Promise<void> {
+  try {
+    new URL(url)
+  } catch {
+    throw new Error(`Invalid URL: ${url}`)
+  }
   this.status = BrowserTabStatus.Loading
   this.url = url
   ...

Also applies to: 136-156

290-338: Consider extracting the buildSelector utility.

The getClickableElements method includes a complex inline buildSelector function (lines 300-327). While it works correctly, extracting it to a separate utility method would improve testability and reusability.

This is a minor maintainability improvement and can be deferred if desired.
