 "definition_md": "**ACP** refers to three unrelated protocols from three organisations at three different steps. Zed's *Agent Client Protocol* connects editors to coding agents (Act). IBM's *Agent Communication Protocol* was an agent-to-agent protocol, archived in August 2025 and merged into A2A (Coordinate, defunct). The OpenAI/Stripe *Agentic Commerce Protocol* lets an agent buy from a merchant (Pay). Published guides routinely state facts about one as though they applied to all; the widely repeated claim that \"ACP merged into A2A\" is true only of IBM's. A fourth, IBM's *Agent Commerce Protocol*, could not be verified as a distinct specification on 2026-09-05.",
