Durable Objects

durable-objects

Build, debug, or review Cloudflare Durable Objects code for persistent state and coordination.

Install

Run this in your project folder. It works with Claude Code, Cursor, Codex and dozens of other agents.

$ npx skills add cloudflare/skills --skill durable-objects

Needs Node.js. Add -g to install for every project, or -a claude-code to skip the agent picker.

How to use Durable Objects

Once it's installed, Claude reads this skill on its own whenever a request matches what it's for, so you don't have to mention it by name. In Claude Code you can also run it directly by typing /durable-objects.

It contains no scripts, only instructions and reference files, so it can't run code on its own.
