Repository-level context files

Files in repository root (e.g., AGENTS.md, CLAUDE.md) providing context to AI agents for coding tasks. Common practice to guide AI behavior.

• ETH Zurich study (2026): Repository-level context files (e.g., AGENTS.md, CLAUDE.md) can degrade AI agent performance, contradicting industry practice.
• Study title: “Evaluating AGENTS.md: Are Repository-Level Context Files Helpful for Coding Agents?”
• Performance Impact: Claude.md and agents.md files can cause Claude to perform worse.
