About

I'm Xand Reed. I build efferent, an open-source coding agent that lives in the terminal: Effect.ts and Bun underneath, a modal multi-pane TUI on OpenTUI and SolidJS on top, multi-provider through @effect/ai, and evals colocated with the code they judge.

The bet behind both the agent and this blog: AI engineering is still engineering. Capabilities should be services with typed errors, provider choice should be runtime state rather than architecture, and an agent without evals is a demo. Everything here is built in public — posts lead with an artifact (a diff, a benchmark, an eval run), not an opinion.

And no React. Not on the blog, not in the terminal.
