agents-md-refactor
Refactor an existing AGENTS.md that is too long, has too much inline content, or lacks nested structure. Use when the user says "my AGENTS.md is too long", "split my AGENTS.md", "optimize my context file", "refactor AGENTS.md", or "/agents-md:refactor". Analyzes the file, proposes a split plan, and executes it — creating nested AGENTS.md files and slimming the root file. Distinct from agents-md:check (audit only) and agents-md:create (greenfield).
