YashAi-Tech/voltagent ? reverse-engineered prompt

Build me a VoltAgent project that shows how to create an AI assistant with memory, tools, and a simple multi step workflow.

I want a clean starter app that includes one helpful agent, a couple of example tools like weather or expense checking, and a workflow that ties a few actions together in a realistic way. Please make it easy to run locally, with clear setup instructions, sensible defaults, and a simple example I can open right away to see it working.

If it makes sense, include support for saving memory between runs, streaming responses, and a basic server so I can try it from a browser or API client. Also add a few examples or sample prompts so I can understand how to use it. Use the current VoltAgent docs online if you need to, and make the code feel polished enough for someone to build on top of it.
