A lightweight example demonstrating how to build a simple agent using the Anthropic SDK with a virtual file system and Pyodide.

This is a contrived example that demonstrates agent capabilities. The agent:

1. Looks up the current IP address from a well-known file
2. Generates an image based on that IP address

npm i
export ANTHROPIC_API_KEY='...'
node mini-agent.js

The agent uses a virtual file system which provides a magic /network folder. It only has a single file in it called current-ip and accessing it will asynchronously fetch the current ip from icanhazip.com in a web worker.

The agent persists per-turn state in ./agent-cache. You can delete cache files after a run to observe how the agent recovers from a missed turn. This attempts to demonstrate how to implement durable execution.

Final output artifacts are placed in ./output.
