Generate HTML artifacts for code review, PR explanation, and codebase understanding — rendered diffs with inline annotations, severity-coded findings, refactor risk maps, before/after migration views, and subsystem walkthroughs. Use whenever the user wants to review, explain, or understand a PR, refactor, codebase area, or subsystem — especially before merging, when onboarding others to a change, or when the GitHub diff view doesn't show enough context. Default to attaching an HTML explainer to every non-trivial PR.

From the source SKILL.md

The default GitHub diff view is fine for tiny PRs and useless for anything that touches multiple files, has subtle ordering, or involves a refactor. HTML lets you render the actual diff with margin annotations, severity tags, flowcharts of what changed, and risk maps showing which areas to look at hardest.

What this skill does

HTML Code Review 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-code-review/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use whenever the user wants to review, explain, or understand a PR, refactor, codebase area, or subsystem — especially before merging, when onboarding others to a change, or when the GitHub diff view doesn't show enough context. Default to attaching an HTML explainer to every non-trivial PR.
