Create and review Cloudflare Durable Objects. Use when building stateful coordination (chat rooms, multiplayer games, booking systems), implementing RPC methods, SQLite storage, alarms, WebSockets, or reviewing DO code for best practices. Covers Workers integration, wrangler config, and testing with Vitest. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'durable-objects' ] || [ -L ~/.agents/skills/'durable-objects' ]; then echo 'A skill folder named durable-objects already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/openai/plugins' "$d" && git -C "$d" checkout --quiet 'd420d13051bffe4543ed39e30fa46b87148e47dd' -- 'plugins/cloudflare/skills/durable-objects' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/cloudflare/skills/durable-objects' ~/.agents/skills/'durable-objects' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'durable-objects' ~/.claude/skills/'durable-objects' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
