Architecture diagrams answer the questions that come up most often during incidents and design reviews: what talks to what, who owns what, where does the data live, what fails when X goes down. A good HTML system diagram is the document you open during the incident, not the one you write after.
HTML Architecture Diagrams is a community-contributed Claude Code skill in the frontend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/html-architecture-diagrams/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use whenever the user wants to visualize, document, or explain how a system fits together — across services, regions, queues, caches, databases, or organizational boundaries. Reach for this whenever the explanation would otherwise involve sentences like "service A talks to service B which writes to queue C".
The HTML Architecture Diagrams Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 159,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

SKILL.md from the source repository to ~/.claude/skills/html-architecture-diagrams/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. HTML Architecture Diagrams is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
