Cascade offers three distinct modes, each with a different set of capabilities designed for specific workflows.

You can switch between different modes using the mode toggle below the Cascade input box, or by using the keyboard shortcut ⌘+. (Mac) or Ctrl+. (Windows/Linux).

​
Code Mode

Code mode is Windsurf’s default fully agentic mode, designed for making changes to your codebase. In Code mode, Cascade can:
  • Create, edit, and delete files
  • Run terminal commands
  • Search and analyze your codebase
  • Install dependencies
  • Execute multi-step tasks autonomously
Use Code mode when you want Cascade to actively work on your project and implement changes.
We recommend you use Code mode as your default mode for most tasks.

​
Plan Mode

Plan mode helps you think through complex tasks by developing a detailed implementation plan before writing any code. In Plan mode, Cascade will:
  • Explore your codebase to understand the current state
  • Ask clarifying questions to ensure the plan aligns with your goals
  • Provide multiple options for you to choose from with an interactive interface
  • Present a detailed plan, written in an external Markdown file, with implementation steps
When Cascade is finished, you can click “Implement” on the plan file to automatically switch to Code mode and begin implementing the plan.

​
Continuing from a plan

The markdown file created in plan mode can be particularly useful for continuing work across multiple sessions. Plans are stored in your ~/.windsurf/plans directory and are available in the @mentions menu. By mentioning a plan file, you can continue implementation with a fresh context. This can be particularly useful when an initial implementation went awry: just discard the original changes, tweak the plan file, and click “Implement” to attempt implementation again in a new conversation.

​
Exiting plan mode

There are multiple different ways to move from planning to implementation:
  • Click the “Implement” button on the plan file
  • Change your mode to Code mode in the input box
  • Let the agent automatically switch to Code mode when it detects that you’re ready to implement

​
Ask Mode

Ask mode is a read-only mode optimized for questions and exploration. In ask mode, Cascade can search and analyze your codebase, but cannot make any changes.
