Think agents now use a @cloudflare/computer workspace

Think and Agent Skills now use the workspace from @cloudflare/computer as well as the filesystem tools. A JavaScript execution environment can be configured by adding the JavaScriptWorkerBackend.

@cloudflare/shell is deprecated, and so is Think's createExecuteTool. These will no longer be developed nor supported from today onwards.

import { Think } from "@cloudflare/think"; import { Workspace } from "@cloudflare/computer"; import { WorkerJavaScriptBackend } from "@cloudflare/computer/backends/worker-javascript"; export class MyAgent extends Think { workspace = new Workspace({ storage: this.ctx.storage, backends: [ new WorkerJavaScriptBackend({ id: "js", loader: this.env.LOADER }), ], }); }

import { Think } from "@cloudflare/think"; import { Workspace } from "@cloudflare/computer"; import { WorkerJavaScriptBackend } from "@cloudflare/computer/backends/worker-javascript"; export class MyAgent extends Think<Env> { override workspace = new Workspace({ storage: this.ctx.storage, backends: [ new WorkerJavaScriptBackend({ id: "js", loader: this.env.LOADER }), ], }); }

Migrate your workspace data

This is a breaking change. @cloudflare/computer stores files in different tables from @cloudflare/shell, and there is no automatic data migration between workspace formats. To keep an existing workspace, copy its files with the script in Migrating from @cloudflare/shell to @cloudflare/computer. Otherwise your agent will start with an empty workspace, though the original data will still be present in the existing tables.
