The Mermaid Architect skill is a diagram and documentation system with specialized guides and code-to-diagram capabilities. It covers decision trees, usage patterns, a resilient workflow, unicode semantic symbols, Python utilities, high-contrast styling, file organization, and a learning path with a "when to use what" matrix. Well suited to agents that produce architecture docs, flowcharts, and design documents in Markdown-based repositories.
