Introducing Cascade: Your Coding Agent

You’ve now used Cascade to handle small tasks like renaming classes, refactoring files, or recalling functions from your codebase. That was a glimpse of Cascade’s basic functionality. This section will look more closely at how it works under the hood.

Cascade operates in two main modes: Write mode and Chat mode (sometimes called Read mode). While both use the same underlying model, they’re optimized for different workflows. Knowing when to switch between them is key to working efficiently.

We’ll start by explaining how each mode works. Then, we’ll explore two powerful features: Web Search, which brings in real-time external knowledge, and App Deploys, which simplifies shipping your application.
