To test: 1. Sign in to https://claude.ai in Chrome. 2. Click the extension icon. 3. The popup shows a masked sessionKey and a "Copy sessionKey" button. 4. Clicking Copy writes the value to the clipboard. If you are not signed in, the popup shows the empty state with an "Open claude.ai" button. The extension makes no network requests. It only reads the sessionKey cookie via chrome.cookies and writes to the clipboard on an explicit click. ``` ## Review risk The `cookies` permission and authentication information are sensitive. The extension is deliberately minimal and local-only, but review may take longer. If rejected, distribute the ZIP as an unpacked extension or GitHub release.
