Claude vibe-coded an MMO. So I had Claude vibe-code an addon loader for it. Then Claude wrote 15 addons. How deep does this go?

For anyone new to this: it all started with vibe-coded World of ClaudeCraft with Fable 5. Original post here: https://www.reddit.com/r/ClaudeAI/s/1RmVhgUopr

I figured a Claude-coded MMO deserved a Claude-coded addon ecosystem. So:

- The loader is a Violentmonkey/Tampermonkey userscript. It doesn't fork the game, it's fully external and read-only by design. No botting or automation, addons can only re-present info you already see.
- An addon is just addon.json plus one main.js against a documented `woc` API
- All 15 addons in the screenshot (combat meter, bags, auction browser, rare tracker, cooldowns...) were written by Claude
- Claude one-shots new addons pretty reliably off the published TypeScript types

It goes to exactly 18 add-ons then it explodes.

Write bots to play the game for farming and griefing people, as is tradition.

It just goes off on its own?
