Wasm Agent

This lets you spin up Claude agents that run in WebAssembly sandboxes, which means they can't touch your actual filesystem or do anything destructive to your system. You create an agent with a config, send it prompts, give it specific tools, and manage files within its isolated environment. The main win here is safety when you're experimenting with agent behaviors or running code you don't fully trust. You can also export the whole thing as a portable package that runs anywhere WASM does. It's overkill if you're just doing basic scripting, but if you're building agent systems where isolation actually matters or you need reproducible execution across different environments, it solves that problem cleanly.
