Traction scoreGitHub stars can be faked, so popularity alone can be misleading. Traction Score looks for broader signs of recent attention, adoption, and active maintenance.
This skill enables technical writers and software engineers to render architecture visualizations, data models, and system workflows without a browser. It converts Mermaid syntax into scalable SVGs for documentation or Unicode art for terminal environments.
By providing fifteen built-in themes and custom color support, the tool streamlines the creation of consistent visual assets for READMEs, pull requests, and technical slides.
Compatible AgentsThe repository documents support for these agents. The skills may also work with other agents that can load SKILL.md files, but they may need some setup or small changes.
Replace [workflow description] with a short process and its decisions.
Replace [output directory] with your desired output location.
Node.js 16 or newer; run bundled scripts from the directory containing SKILL.md or use absolute script paths.
Use pretty-mermaid to turn this workflow description into a small flowchart: [workflow description]. Save the Mermaid source and a themed SVG in [output directory], preserving my terminology and relationships. Inspect the rendering for unclear labels or crowded layout, and return the source and output paths plus the selected theme.
Replace [source .mmd path] with an existing Mermaid source file.
Replace [output .png path] with a new destination file path.
Node.js 16 or newer; run bundled scripts from the directory containing SKILL.md or use absolute script paths.
Use pretty-mermaid to render [source .mmd path] as a themed PNG at [output .png path]. Inspect the result for clipping, crowded layout, and unclear labels. Keep the existing source unchanged and return the output path and selected theme.
