agentscope-ai/agentscope-typescript ? reverse-engineered prompt

Build me a TypeScript project for agent powered apps, with a core library and a simple desktop demo app.

I want the library to make it easy to create an assistant that can talk to a model, use tools, keep memory, ask for human approval when needed, and stream responses as events so the UI can show what is happening in real time. It should also support adding custom skills, reading and writing files, running commands, and connecting to external tools through standard protocols.

Please include a clean example app that shows a helpful assistant in action, something like a desktop chat or workspace helper. Make the demo feel real, with streaming replies, tool usage, and a basic way to see agent activity as it runs.

Keep it production friendly, easy to extend, and organized so the core agent logic is separated from the example app. If you need to check current docs for any model or integration details, go ahead and look them up online.
