Cosmos Chrome Extension Analysis

Purpose and Intention: Cosmos is designed to enhance productivity by integrating AI capabilities directly into the browser. It offers features like email drafting, website translation, spell checking, and note-taking.

Code Insights:

1. Installation Behavior:

   • On installation, the extension checks if it has redirected the user to a welcome page. If not, it opens a new tab to https://www.cosmos-suite.ai/compagnon.

   chrome.runtime.onInstalled.addListener(async (details) => {
     if (details.reason === 'install') {
       const data = await chrome.storage.local.get(['hasRedirectedOnInstall']);
       if (!data.hasRedirectedOnInstall) {
         await chrome.storage.local.set({ hasRedirectedOnInstall: true });
         chrome.tabs.create({
           url: 'https://www.cosmos-suite.ai/compagnon',
           active: true,
         });
       }
     }
   });
   

2. User Authentication Management:

   • Handles user sign-in, session updates, and sign-out processes. It updates the local storage with user and session data and notifies all tabs of authentication state changes.

   chrome.runtime.onMessage.addListener((request, sender, sendResponse) => {
     switch (request.type) {
       case 'SIGN_IN_SIGNAL':
       case 'SESSION_UPDATE':
         chrome.storage.local.set({
           user: request.data.user,
           session: request.data.session,
           isLoggedIn: true,
         }, () => {
           chrome.tabs.query({}, (tabs) => {
             tabs.forEach((tab) => {
               chrome.tabs.sendMessage(tab.id, {
                 type: 'AUTH_STATE_CHANGED',
                 data: {
                   isLoggedIn: true,
                   user: request.data.user,
                   session: request.data.session,
                 },
               });
             });
           });
         });
         sendResponse({ success: true });
         break;
       // Other cases...
     }
   });
   

3. Side Panel Management:

   • Opens a side panel when the extension icon is clicked or based on certain conditions.

   chrome.action.onClicked.addListener(function (tab) {
     chrome.sidePanel.open({ windowId: tab.windowId });
   });
   

4. Network Activity:

   • Opens external URLs in new tabs when requested.

   case 'OPEN_EXTERNAL_URL':
     chrome.tabs.create({ url: request.url })
       .then(() => sendResponse({ success: true }))
       .catch((error) => sendResponse({ success: false, error: error.message }));
     return true;
   

5. Data Handling:

   • Utilizes Chrome's local storage to manage user data and session information securely.

Conclusion: The code primarily focuses on enhancing user experience by managing authentication, opening necessary tabs, and handling side panel interactions. There are no strong indicators of malicious behavior such as unauthorized data exfiltration, obfuscation, or backdoors.
