This paper proposes Lore, a lightweight protocol that repurposes git commit messages as structured decision records for AI coding agents. Using native git trailers, Lore encodes constraints, rejected alternatives, agent directives, and verification metadata directly in commits — requiring no infrastructure beyond git itself. The protocol is queryable via a standalone CLI and discoverable by any agent capable of running shell commands. The paper formalizes the protocol, compares it against five competing approaches (ADRs, Code Digital Twin, Git Context Controller, RAG systems, and AI-generated commit messages), and outlines an empirical validation path.
