      ## External File Loading

      CRITICAL: When you encounter a file reference (e.g., @rules/general.md), use your Read tool to load it on a need-to-know basis. They're relevant to the SPECIFIC task at hand.

      Instructions:

      - Do NOT preemptively load all references - use lazy loading based on actual need
      - When loaded, treat content as mandatory instructions that override defaults
      - Follow references recursively when needed

      ## Development Guidelines

      For TypeScript code style and best practices: @docs/typescript-guidelines.md
      For React component architecture and hooks patterns: @docs/react-patterns.md
      For REST API design and error handling: @docs/api-standards.md
      For testing strategies and coverage requirements: @test/testing-guidelines.md

      ## General Guidelines

      Read the following file immediately as it's relevant to all workflows: @rules/general-guidelines.md.
    '';
  };
  nmt.script = ''
    assertFileExists home-files/.config/opencode/AGENTS.md
    assertFileContent home-files/.config/opencode/AGENTS.md \
      ${./AGENTS.md}
  '';
