mermaid

The skill's footprint is coherent with its purpose: it derives diagram data from context, uses local Emacs color/mode information, renders a Mermaid diagram to a temporary PNG via a local headless Chromium tool, and outputs a Markdown image reference. There are no evident security risks such as credential handling, untrusted downloads, or data exfiltration. The approach is reasonably contained to the user’s environment and artifacts.
