Mermaid Skill (Agents365-ai)
Leading#2 in Skillslow confidence
The most complete standalone Mermaid skill (~146★) — natural language to validated .mmd with 11+ diagram types and mmdc/Kroki rendering to PNG/SVG/PDF.Our read
Why it ranks #2
A newer standalone skill at ~146 GitHub stars with 11+ diagram types and a documented validation/export loop; it ranks tenth because adoption and independent community feedback remain small.Here is the catch
small ~146-star adoption base and almost no independent review signal
rendering depends on an external mmdc installation or Kroki service
limited to Mermaid rather than supporting multiple diagram engines
Does this well
validation-first workflow catches syntax errors before export
supports local mmdc rendering with a zero-install Kroki fallback
adds visual review and iterative cleanup beyond basic Mermaid generation
