RuleStack compares instruction file formats for coding agents

RuleStack compares instruction file formats for coding agents

RuleStack compares the instruction files coding agents load, including AGENTS.md, CLAUDE.md, Cursor rules and Copilot instructions.

The formats behave differently inside the same repository. AGENTS.md supports nested files, but no imports. CLAUDE.md adds @path imports and user-level instructions. Cursor rules add glob-based activation, while Copilot supports glob-scoped files but no imports.

RuleStack is for developers deciding which format belongs in a repository. You get the source files, capability comparisons and measured adoption data. I keep it free, with no account and no write path. how instruction files load AGENTS.md: nested, no imports CLAUDE.md: nested, @path imports Cursor rules: globs and imports Copilot instructions: globs, no imports RuleStack keeps each format's loading behavior beside the source files and measured adoption data.
