TypeSafe founder's design notes on building a coding agent around Jev
A 12-page engineering synthesis of Diogo Almeida's design notes covers making agent state explicit and typed, letting Jev decide context, routing by cost and context, loading tools on demand, and programmable permissions.
Diogo Almeida, founder of TypeSafe shared design notes on building a coding agent around Jev Someone independently turned those ideas into a 12-page engineering synthesis Some interesting ideas: → Make agent state explicit and typed → Let Jev decide what context matters → Route based on cost + context, not just model capability → Load tools only when needed → Make permissions programmable → Share retrieval across background agents The big idea: The leverage isn't just in the model It's in what you put in front of it Worth reading if you're building coding agents 👇 Read the PDF
