Treat folder structure as agentic architecture, not just human organization

A new arXiv paper ("Interpretable Context Methodology: Folder Structure as Agentic Architecture") argues your directory layout is itself a context-engineering lever: agents navigate and retrieve by path semantics, so a tree organized around clear, self-describing boundaries lets an agent locate the right code without burning session tokens re-discovering structure. The practical takeaway is to name and group directories for machine navigation (predictable, intent-revealing paths) the same way you'd write a good CLAUDE.md.
