Create Agents Md

This creates AGENTS.md files for keeping project-specific instructions in your repo. Use it when you need small, inline rules like code style conventions, folder-scoped guidance in monorepos, or test-specific patterns that don't belong in a reusable skill. The structure is straightforward markdown without metadata, lives at your project root or in subdirectories where behavior diverges, and works best when you keep it short with concrete references to existing code examples rather than long explanations. The guide is clear about the boundaries: if it's reusable across projects or complex enough to need scripts, make it a skill instead.
