Cursor debug
ComponentUpdates related to the debug component of Cursor.
All DEBUG Features
- Introduced the new Agents Window interface allowing users to run many agents in parallel across repos and environments (locally, worktrees, cloud, SSH).(3.0)
- Enabled Design Mode within the Agents Window to annotate and target UI elements directly in the browser for more precise feedback.(3.0)
- Added keyboard shortcuts for Design Mode: → ⌘+Shift+D to toggle, Shift+drag to select an area, → ⌘+L to add element to chat, and → Option+click to add element to input.(3.0)
- Added Agent Tabs in the Editor to view multiple chats side-by-side or in a grid.(3.0)
- Added a new command /worktree that creates a separate git worktree for isolated changes.(3.0)
- Added a new command /best-of-n that runs the same task in parallel across multiple models in isolated worktrees and compares outcomes.(3.0)
- Enabled MCP Apps to support structured content for richer tool outputs.(3.0)
- Added directory group name to audit logs for improved human readability.(3.0)
- Added a team-level Admin setting to restrict creating, editing, and deleting team secrets to Admins.(3.0)
- Added an Enterprise Admin control for disabling "Made with Cursor" code attribution for the entire team.(3.0)
- Enabled Cloud Agents to use the software they create for testing changes and demonstrating work.(02-24-26)
- Introduced isolated Virtual Machine (VM) environments for each Cloud Agent running on your codebase, complete with a full development environment.(02-24-26)
- Cloud Agents now produce merge-ready Pull Requests (PRs) that include artifacts like videos, screenshots, and logs for easier review.(02-24-26)
- Introduced Subagents, specialized, independent agents that run in parallel with custom configurations for faster, more focused task execution.(2.4)
- Enabled direct image generation from the agent using text descriptions or reference uploads, saving previews inline and to the assets/ folder.(2.4)
- Launched Cursor Blame (Enterprise plan feature) extending git blame with AI attribution, showing which lines were AI-generated (by Tab completions or agent runs) versus human-written.(2.4)
- Added the ability for agents to ask clarifying questions during Plan and Debug modes, allowing them to continue working while waiting for user input.(2.4)
- Enabled building custom subagents and skills that utilize the new 'ask question tool'.(2.4)
- Introduced Debug Mode which instruments the app with runtime logs to help reproduce and fix tricky bugs across stacks, languages, and models.(2.2)
- Enabled a new browser sidebar and component tree for simultaneous design and coding, allowing real-time element manipulation, color updates, layout testing, and CSS experimentation.(2.2)
- Added the ability to select multiple visual elements and describe desired changes in text to initiate an agent for visual updates.(2.2)
- Added support for inline Mermaid diagrams in Plan Mode, allowing agents to automatically generate and stream visuals into plans.(2.2)
- Enabled sending selected to-dos to new agents for more granular control over plan building.(2.2)
- Implemented Multi-agent judging, which automatically evaluates parallel agent runs and recommends the best solution with an explanation.(2.2)
All DEBUG Bug Fixes
- Fixed text area behavior for Network Access Controls so pressing Enter reliably adds a newline at the end of the input.(3.0)
- Fixed hooks loading so multi-root workspaces correctly read project hook files from all workspace folders instead of only the first one.(3.0)
- Fixed a markdown parsing bug where parenthesized HTTP(S) links could be misread as citations.(3.0)
- Fixed todo card visibility to prevent them from disappearing after all todos complete.(3.0)
- Fixed Composer queued prompts that were not resuming automatically after editing operations.(3.0)
- Fixed picker behavior for disabled but selectable models by removing misleading styling and auto-enabling the model upon user selection.(3.0)
- Fixed a bug where expanding/collapsing thinking blocks didn't work while streaming was still in progress.(3.0)
- Fixed a bug where Shift+Enter line breaks weren't treated as multiline content, preventing the prompt input field from staying in an incorrect state.(3.0)
- Fixed 11 unspecified bugs (as noted in the release notes summary).(2.4)
Releases with DEBUG Changes
3.010 features8 fixesCursor 3 introduces the powerful new Agents Window, enabling users to run multiple agents in parallel across various environments with improved visibility and control. This release also adds Design Mode for precise UI targeting and Agent Tabs for managing multiple chats simultaneously. Several usability improvements focus on performance, such as faster large-file diff rendering, alongside key bug fixes across input handling and workspace loading.
02-24-263 featuresThis release introduces powerful Cloud Agents that operate within isolated VMs to build, test, and demo software directly from your codebase. Agents now deliver merge-ready Pull Requests complete with review artifacts, and are accessible across all Cursor platforms.
2.45 features1 fixThis release significantly enhances agent capabilities by introducing Subagents for parallel, specialized task execution and enabling direct image generation within the agent interface. Additionally, Enterprise users gain Cursor Blame for detailed AI attribution tracking, and agents can now proactively ask clarifying questions during complex workflows.
2.26 featuresThis release introduces powerful new debugging capabilities with Debug Mode and a visual development workflow via the new browser sidebar and component tree. Plan Mode is enhanced with inline Mermaid diagram support, and Multi-agent judging provides automated selection of the best solution when running agents in parallel.
