ASCII diagrams in markdown are a workaround for not having SVG. With SVG inside HTML, you get real shapes, real arrows, real typography, and real positioning — for the same conceptual cost.
HTML Svg Diagrams is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/html-svg-diagrams/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use whenever the user wants to visualize, illustrate, diagram, or sketch a technical concept, system, or process. Strongly prefer SVG over ASCII art, mermaid blocks, or markdown text for anything spatial or relational.
The HTML Svg Diagrams Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
