📝 First blog in a long time! I always like “flow-based” programming, and it’s a very powerful paradigm. LangGraph lets you codify complex workflows as graphs, and also integrates really well with LangChain, if your workflow is LLM-driven.

This is what I have been working on! Shopify’s monorepo “world”, its nixification, building our Slack-based agent River and now generalizing River’s underlying agentic sandbox infrastructure called Aquifer. Finally I got someting I can share about it!

`builtins.wasm` is now a (experimental) thing in
