As a Technology Leader and CAIO, I have observed that the evolution of Agentic AI has shifted the focus from "prompt engineering" to "context engineering." The emergence of files like AGENTS.md, CLAUDE.md, and SKILLS.md represents a move toward standardized, repository-level governance for AI agents.
The following table provides a structured comparison of these "Context Manifest" files used in modern AI-augmented development environments.
