Coframe Annotations extension

Multi-user, agent-collaborative annotation surface for live websites. Pin feedback / bugs / questions to any element, capture forensic context, ship as JSON via webhook to the team's queue.

What you get

• Five marker kinds — feedback, bug, design, suggestion, question
• Four target types — element, text range, area, multi-select
• Threaded comments per pin
• Forensic JSON: DOM ref, React fiber traversal, screenshot, scroll position
• Closed Shadow DOM + Preact, ~3 KB on the host page
• Webhook POST outbound, window.__coframeAnnotations inbound

Install

1. Clone growth-engine
2. cd coframe-annotations/frontend && pnpm install && pnpm build
3. chrome://extensions → Developer mode → Load unpacked → pick dist/

Chrome Web Store listing coming. Cross-user persistence server (the backend/ v2) is on the roadmap.
