  "supportingContext": "The article describes a practitioner-built plugin for Anthropic's Claude desktop app in Cowork mode, distributed via a GitHub repository for paid subscribers. The methodology centers on structured skill files that function as decision trees with specific criteria, scoring rubrics, and output formats, rather than free-form persona prompts. Skills cross-reference one another so commands like /audit-page can chain multiple knowledge files into a single unified deliverable. For marketing practitioners, the approach offers a reproducible way to standardize audits, email sequences, and SEO checks without writing prompts each time. The author positions plugin orchestration as a maturity step beyond prompt libraries and Claude Projects, though the performance claims remain self-reported rather than independently benchmarked.",
