Скачать или смотреть AGENTS.md Doesn't Work ? (Here's the Data)

AGENTS.md is the official best practice for coding agents. Put a context file in your repo, tell the agent how your project works, and it'll perform better. That's the theory.
A team from ETH Zurich and LogicStar.ai just ran the first rigorous evaluation — across Claude Code, Codex, and Qwen Code — and the results are surprising. Auto-generated context files reduce performance and increase costs by 20%+. Developer-written ones barely help. But the reason they don't work is more interesting than the headline.
