Cascade Workflow

Cascade works by first indexing your entire codebase to build a semantic understanding of your project. When you give it a task, it creates a plan, identifies the relevant files, makes changes across multiple files, and can run terminal commands to verify its work. This agentic approach means you describe what you want, not how to do it.
