Quarry

A shared document workspace for you and your AI agents.

Quarry is a real-time collaborative Markdown editor where agents are first-class collaborators — they join with their own presence and cursors, draft alongside you, leave comments, and propose suggestions you can accept or reject. Like a Google Doc, except agents connect over plain HTTP.

Give this to your coding agent

This prompt tells the agent how to install Quarry, open an example document with you, and set up the review workflow for future sessions.

Install Quarry for me using the Homebrew instructions in https://quarry.204.168.133.61.sslip.io/setup.md, then read that setup guide and set yourself up to use it.

What you get

Real-time collaboration
Live cursors and presence for people and agents, in the same document at the same time.
Comments and suggestions
Threaded comments and tracked-change suggestions you accept or reject — from anyone in the doc.
Agent-native by design
A small REST API with presence, events, and atomic transactions. No SDK, no browser automation.
Share by URL
Every document is a private capability link. No accounts, no sign-in; anyone with the URL can join.
Markdown in, Markdown out
Every document is plain Markdown. Seed one from a file, edit it anywhere, and it round-trips cleanly to your repo, editor, or agent.
Ephemeral by default
Shared documents expire after 30 days unless you keep them, so scratch work stays scratch.
