Claude Code: why HTML beats Markdown for complex output
Thariq Shihipar (Claude Code team, Anthropic) argues that HTML should replace Markdown as the default format for Claude outputs — especially when visual structure, layout, and interactivity matter.
• Markdown's token efficiency no longer matters now that context windows are cheap
• HTML lets you color-code severity, render diffs with inline annotations, and build interactive reviews
• Prompt example: request an HTML artifact that describes a PR with margin notes on the parts you don't understand
