Senior Engineers Overfit AI Agent Tools to Context Models Cannot See

Philipp Schmid of Google DeepMind argues that senior engineers often struggle with AI agents because they design tools around context they personally understand but the model cannot see. In his account, agent-ready systems need explicit tool schemas, semantic state, recoverable errors, eval-based reliability measures and disposable harnesses, because engineers are managing probabilistic behavior rather than controlling a deterministic flow.
