Agents Md

This enforces research-backed best practices for keeping agent documentation minimal and high-signal. It creates or updates AGENTS.md files following strict length limits (under 60 lines, never over 100) because instruction-following degrades with document bloat. The approach is opinionated: analyze the project's actual toolchain first, use headers and bullets only, reference existing docs instead of duplicating them, and prioritize file-scoped commands over expensive full builds. It includes required sections for package manager, commit attribution, and file-scoped commands, while explicitly banning filler like "Welcome to" intros or duplicating linter configs. Useful if your agent docs have become sprawling novels or you want to start with proven conventions instead of reinventing them.
