Developers in the HumanLayer orbit are discussing jev, a new building block for AI systems. @dexhorthy calls it the best excuse to re-read 12 Factor Agents: tool calling can be decomposed into classify+action, and if you design AI programs as pipelines that switch between classification, data structuring, deterministic code, and small agent-shaped loops, jev is a wonderful building block. @dillonmulroy argues it resonates because it unlocks composing AI into systems and products rather than AI becoming the whole system — a missing primitive. The referenced 12-factor-agents repo (26k stars) codifies principles for production-grade LLM applications.
