I mapped every agent config file (AGENTS.md, CLAUDE.md, llms.txt, .cursorrules, SKILL.md...) and tagged how widely each is actually used

Every tool ships its own magic file now and after a while the names all blur together. I put together a guide to the ones agents actually read and write, with a tag on each for real adoption instead of hype.

21 conventions, 11 categories. The tags are adopted / emerging / proposed, so you can tell a shipping standard from a blog post.

Examples are fetched from public repos by a script with the source kept at the top of each file, nothing made up. I also tried to stay honest about the hype: llms.txt is published all over the place but no major provider has actually confirmed reading it, and the list says that out loud.

MIT. If an adoption tag looks wrong to you I'd rather hear it, that's the hardest part to keep right.
