Run the prompt
Open Claude Code in an empty folder and paste the builder prompt from Your kit. It writes a folder: manifest.json, a popup, an options page, a background service worker and icons and opens it. Let the first run finish before you touch anything.
The builder prompt is in the kit. Buy it to copy the prompt and unlock steps 2–5.
What you should see
Open chrome://extensions, turn on Developer mode, choose Load unpacked and pick the folder. The icon appears; click it and press "Group by domain".
If it goes wrong
If the agent asks a clarifying question, answer "use your judgement and keep it self-contained".
Try your own
Use it for two minutes before you change anything. Notice what you'd change first; that's step 3.
Steps 2–5 are in the kit.
Change the popup actions, add your own auto-group rule, publish with your name on the badge.
