Poem

Ogres have layers, and so does this guide, 📚
A roadmap for Claude, with nowhere to hide,
YAML and warp IDs, all neatly arranged,
In this swamp of a registry, nothing's been changed—
Just wisdom for those who wade through the code. ✨

In `@AGENTS.md`:
- Around line 1-6: The header and internal branding currently read "CLAUDE.md"
and mention "Claude Code (claude.ai/code)" which conflicts with the file name
AGENTS.md and the PR goal of tool-agnostic compatibility; update the top-of-file
header and any occurrences of "CLAUDE.md" and "Claude Code (claude.ai/code)" to
a neutral, tool-agnostic title (e.g., "AGENTS.md" or "AI coding assistants") and
replace specific references with generic phrasing like "AI coding assistants" or
"assistant tools", ensuring the concise guidance remains but removes
Claude-specific branding throughout the file.
