Agents, Workers - @cloudflare/codemode v0.1.0: a new runtime agnostic modular architecture

The @cloudflare/codemode package has been rewritten into a modular, runtime-agnostic SDK. Code Mode enables LLMs to write and execute code that orchestrates your tools, instead of calling them one at a time. This can (and does) yield significant token savings, reduces context window pressure and improves overall model performance on a task. The new Executor interface is runtime agnostic and comes with a prebuilt DynamicWorkerExecutor to run generated code in a Dynamic Worker Loader . Breaking changes Removed experimental_codemode() and CodeModeProxy — the package no longer owns an LLM call or model choice New import path: createCodeTool() is now exported from @cloudflare/codemode/ai New features createCodeTool() — Returns a standard AI SDK Tool to use in your AI agents. Executor interface — Minimal execute(code, fns) contract. Implement for any code sandboxing primitive or runtime. DynamicWorkerExecutor Runs code in a Dynamic Worker . It comes with the following features: Network isolation — fetch() and connect() blocked by default ( globalOutbound: null ) when using DynamicWorkerExecutor Console capture — console.log/warn/error captured and returned in ExecuteResult.logs Execution timeout — Configurable via timeout option (default 30s) Usage JavaScript import { createCodeTool } from "@cloudflare/codemode/ai" ; import { DynamicWorkerExecutor } from "@cloudflare/codemode" ; import { streamText } from "ai" ; const executor = new DynamicWorkerExecutor ( { loader : env . LOADER } ) ; const codemode = createCodeTool ( { tools : myTools , executor } ) ; const result = streamText ( { model , tools : { codemode }, messages , } ) ; TypeScript import { createCodeTool } from "@cloudflare/codemode/ai" ; import { DynamicWorkerExecutor } from "@cloudflare/codemode" ; import { streamText } from "ai" ; const executor = new DynamicWorkerExecutor ( { loader : env . LOADER } ) ; const codemode = createCodeTool ( { tools : myTools , executor } ) ; const result = streamText ( { model , tools : { codemode }, messages , } ) ; Wrangler configuration wrangler.jsonc { " worker_loaders " : [{ " binding " : "LOADER" }], } wrangler.toml [[ worker_loaders ]] binding = "LOADER" See the Code Mode documentation for full API reference and examples.
