关于

The Mermaid Syntax Validator is a specialized tool designed to prevent broken diagrams in documentation. It scans Markdown files for common Mermaid errors such as unclosed brackets, incorrect C4 model parameters, and invalid sequence diagram arrows. Beyond simple detection, the skill automatically normalizes indentation and fixes syntax issues, making it indispensable for teams maintaining complex architecture diagrams, sequence flows, and ER diagrams directly in their code repositories. It ensures that your technical documentation remains visually consistent and syntactically correct for tools like GitHub, GitLab, and Mermaid Live Editor.
