Phil Schmid: Agents are converging on a single exec tool — Code Mode explained
_philschmid · x · 2026-11-02
Phil Schmid argues agents are collapsing their entire tool catalog into one exec(code) tool. He traces the evolution: few tools → dozens of tools/MCP servers hitting context limits → dynamic tool search → Code Mode (programmatic tool calling), where the model writes TypeScript/Python that chains actions in an isolated sandbox, removing the one-action-per-turn bottleneck. He covers why a typed JS/Python sandbox beats raw bash, why MCP will come back strong in 2027, includes a minimal Gemini 4 Argon example, and recommends testing with pi.
