Markdown Document Canvas
Visualizes and edits markdown documents with real-time text selection and diff highlighting in an external monitor.
The document skill provides Claude Code with a dedicated visual interface for handling rich text content, effectively acting as an external monitor for long-form text tasks. It allows users to review generated content like blog posts, emails, or READMEs in a formatted view rather than raw text. By supporting interactive text selection and visual diff markers—showing green for additions and red for deletions—it creates a collaborative feedback loop where users can precisely highlight areas for Claude to revise or expand upon, streamlining the content creation process within the CLI.
