I will build a chrome extension with manifest v3, content scripts and api calls

I build Chrome extensions on Manifest V3, and I have published to the Chrome Web Store, so I know where the review process trips people up.

What I do:

• Manifest V3 extensions: popup, options page, background service worker
• - Content scripts that read or change a page the way the user actually sees it
• - Calls to your own API or a third-party API, with the permissions declared properly
• - Saved settings with chrome.storage, so the extension remembers what the user chose
• - Packaging, so the extension is ready to submit for store review

What I need from you: a clear description of what the extension should do, which sites it runs on, and any API details or keys it needs.

What you get: the full source in a repo you own, a loaded and tested extension, and notes on the permissions and what the store review will look at.

What I will not do: anything that breaks a site's terms of service, collects user data without the user knowing, or exists only to get around a paywall. If your idea needs that, I will tell you before you order rather than after.
