The central development is the emergence of the terminal as the primary interface for coding agents. @AnthropicAI's launch of Claude Code 1.5, a terminal-native agent, accelerates this shift away from traditional IDEs, a structural change that @karpathy argues is profoundly underrated. This user-facing evolution is mirrored by a fierce, parallel competition to define the underlying infrastructure. @OpenAI's new agent SDK introduces protocol-level primitives for orchestration, a clear attempt to standardize the agent development stack. This standardization, however, creates new centralized risks. Security researchers at @GoogleDeepMind are already publishing red-teaming frameworks for these complex orchestration layers, refuting the notion that agent security is a solved problem. The entire stack, from UX to infra to security, is consolidating simultaneously, indicating the agent development space is entering a new, more serious phase."}
