• Using Claude Code: The unreasonable effectiveness of HTML

  • Summary

    • Argues that HTML is often a better output format than Markdown for Claude Code artifacts because it supports richer layout, clearer visual structure, easier sharing, and lightweight interactivity.
    • Frames HTML artifacts as a way to stay more "in the loop" with Claude when reviewing plans, specs, explainers, and other long-form agent output.

  • Notes

    • Reasons given: higher information density, better readability for long docs, easier browser-based sharing, two-way interactions, and stronger data ingestion from local files, MCPs, browser context, and git history.
    • Suggested use cases: specs and planning, code review and understanding, design prototypes, reports and explainers, and throwaway task-specific editors that export results back into prompts or repo files.
    • Recommended starting point is simple: ask Claude Code to "make an HTML file" or "make an HTML artifact", then turn recurring patterns into reusable skills later.
