Canvas Design Mode and Context Usage Report
Summary
Cursor’s canvas release adds Design Mode, enabling users to select and annotate UI elements directly while guiding edits. The update also turns agent context usage into an interactive canvas report, breaking token consumption across the system prompt, tool definitions, rules, skills, and more. Because the report is interactive, users can ask follow-up questions, customize its answers, or use an embedded Debug with Agent button to seek opportunities to reduce context usage in a new conversation. Other changes include full-screen browser access for shared canvases, prompt-triggering buttons, improved handling of canvas type errors, better component styling, and more chart customization options.
Context
The release focuses on faster canvas editing and better visibility into how agent context is used. It also adds sharing, interaction, reliability, styling, and charting improvements for canvases.
