Claude Code's html-plan plugin turns plans into reviewable HTML pages

Claude Code developer Thariq (@trq212) released html-plan, a plugin that makes Claude Code generate self-contained single-file HTML plans instead of lengthy Markdown.

The page organizes the plan into a layered tree with progressive disclosure, numbered decision points, and in-page feedback that can be pasted back into Claude Code.

Install it with claude plugin marketplace add anthropics/claude-plugins-community, then claude plugin install html-plan@claude-community.
