Claude Code lead targets Markdown "nightmare"

The push for HTML artifacts marks a strategic pivot from simple LLM chat interfaces toward high-fidelity AI-native applications. While Markdown is token-efficient, it fails to support the interactivity needed for multi-step refactors, sortable tables, and live SVG diagrams. The release of Claude Opus 4.7 and its 1-million-token window effectively neutralizes the "token tax" previously associated with verbose HTML outputs, allowing a hybrid "Markdown for agents, HTML for humans" architecture to emerge as the preferred UX pattern for complex coding agents. However, HTML-heavy outputs still present significant challenges for git-based reviews, as diffing large blocks of markup remains notoriously difficult for humans.
