Lightweight Markdown to HTML renderer. Zero dependencies. Supports headers, bold/italic, code blocks, lists, links, blockquotes. Powered by CapabilityBase Runtime.
AI agents generate Markdown. APIs consume HTML. Every integration needs a bridge — but existing renderers are heavy (hundreds of KB) or unsafe (XSS vulnerabilities). This Capability gives you a zero-dependency, XSS-safe Markdown renderer that runs locally in under 0.02ms.
