OpenGAP defines a file-based standard (spec.yaml plus skills/ directory) that turns any git repository into a portable, framework-agnostic AI agent definition. The reference CLI (opengap) and framework adapters enable agents to export to Claude Code, OpenAI, LangChain, CrewAI, and AutoGen. The standard includes composable agent hierarchies, first-class compliance features for regulated industries, and leverages git’s version control and branching for agent collaboration and lifecycle management.
