About this skill
Build secure, isolated code execution environments on Cloudflare Workers. Your knowledge of the Sandbox SDK may be outdated. Prefer retrieval over pre-training for any Sandbox SDK task. When implementing features, fetch the relevant doc page or example first. wrangler.jsonc (exact - do not modify structure): Worker entry - must re-export Sandbox class: Use runCode() for executing LLM-generated code with rich outputs: Languages : python , javascript , typescript State persists within context. Create explicit contexts for production. Base image ( docker.io/cloudflare/sandbox:0.7.0 ) includes Python 3.11, Node.js 20, and common tools. Add dependencies by extending the Dockerfile: Keep images lean - affects cold start time. Expose HTTP services running in sandboxes: Production requirement : Preview URLs need a custom domain with wildcard DNS ( *.yourdomain.com ).
