Quick Review

Excellent skill with comprehensive coverage of Mermaid diagram creation. The description clearly indicates when to use the skill (technical documentation, workflows, architecture), and the detailed workflow covers all major diagram types with extensive syntax examples. Task knowledge is outstanding with step-by-step instructions, code samples, decision matrices, and validation checklists for flowcharts, sequence diagrams, ERDs, C4 architecture, state diagrams, and styling. Structure is very clear with logical progression through diagram types and a helpful decision matrix upfront. Novelty is strong: creating complex Mermaid diagrams from requirements would consume many tokens for a CLI agent and require knowledge of syntax variations across 10+ diagram types. The skill provides reusable patterns, best practices, and comprehensive examples that significantly reduce token cost and cognitive load. Minor improvement could be adding more cross-references if this were part of a larger skill set, but as a standalone skill it is near-optimal.
