Mermaid Diagrams (softaworks agent-toolkit)
Leading#1 in Skillsmedium confidence
The most-adopted diagram Claude Code skill (~2.2k★, whole toolkit) — a mermaid-diagrams SKILL.md for flowcharts, sequence and architecture diagrams.Our read
Why it ranks #1
The parent toolkit has ~2.2k GitHub stars, the strongest adoption signal among the two dedicated agent skills here, but there is no skill-specific star count or meaningful independent review base.Here is the catch
the ~2.2k-star signal belongs to the whole toolkit, not this skill
no automated syntax validation or render-and-review loop is bundled
independent user reviews and skill-specific adoption data are sparse
Does this well
broad reference material covers the Mermaid diagrams software teams use most
clear selection guidance and examples help agents choose an appropriate diagram type
portable Agent Skills packaging works across multiple coding agents
