What are Cloudflare Durable Objects?

Durable Objects are globally unique, stateful objects that provide single-point coordination and strong consistency for Cloudflare Workers applications.

Does this skill support the Durable Objects SQL API?

Yes, it provides comprehensive patterns for using the SQLite-backed storage API, including transactions, cursors, and complex query optimizations.

What is the benefit of using the /do-migrate command?

It provides a safe, interactive workflow for creating, renaming, or transferring DO classes, preventing data loss during deployment transitions.

Can this skill help with wrangler.jsonc configuration?

Yes, the do-debugger agent automatically validates and fixes binding issues, migration tags, and class exports in your configuration files.

How does WebSocket hibernation work in this skill?

The skill implements patterns using ctx.acceptWebSocket and serializeAttachment to keep thousands of connections open while the DO is idle, reducing costs.
