a Chrome Manifest V3 extension that reads the current page, and offers a popup UI that has the page title+content and a textarea for a prompt (with a default value we specify). When the user hits submit, it sends the page title+content to the Anthropic Claude API along with the up to date prompt to summarize it. The user can modify that prompt and re-send the prompt+content to get another summary view of the content.

in the string prompt sent to Anthropic, first include the page title and page content, and finally append the prompt, clearly vertically separated by spacing.
if the Anthropic api call is a 401, handle that by clearing the stored anthropic api key and asking for it again.
add styles to make sure the popup's styling follows the basic rules of web design, for example having margins around the body, and a system font stack.
style the popup body with but insist on body margins of 16 and a minimum width of 400 and height of 600.
inside of background.js, just take the getPageContent response directly
chrome.runtime.onMessage.addListener((request, sender, sendResponse) => { if (request.action === 'storePageContent') { // dont access request.pageContent chrome.storage.local.set({ pageContent: request }, () => { sendResponse({ success: true }); }); } else if (request.action === 'getPageContent') { chrome.storage.local.get(['pageContent'], (result) => { // dont access request.pageContent sendResponse(result); }); } return true; });
inside of popup.js, Update the function calls to
requestAnthropicSummarypopup.jsapiKeychrome.storage.local.get(['apiKey'], (result) => { const apiKey = result.apiKey; requestAnthropicSummary(defaultPrompt, apiKey); }); sendButton.addEventListener('click', () => { chrome.storage.local.get(['apiKey'], (result) => { const apiKey = result.apiKey; requestAnthropicSummary(userPrompt.value, apiKey); }); });
