Definition
Cascade is the agentic coding assistant built into Windsurf, an AI-native code editor originally created by Codeium, that performs multi-step, multi-file coding tasks with awareness of the developer's actions and the ability to run terminal commands autonomously.
Overview
Windsurf (formerly Codeium's editor product) built Cascade as its flagship 'agentic' mode, positioned as going a step further than assistant chat by maintaining continuous awareness of what the developer is doing in the editor — files opened, edits made, terminal commands run — and using that context to propose and carry out coherent multi-step changes without needing every detail restated. Cascade can search the codebase, read and edit multiple files, execute terminal commands, and iterate based on command output (e.g., re-running a failing test and adjusting code until it passes), operating with a configurable level of autonomy from fully manual approval to more automatic execution. A feature Windsurf highlighted at launch was 'Flows,' the combination of Cascade's agentic capability with real-time collaborative awareness between human and AI — the idea that the AI stays in sync with the human's live editing state rather than working from a stale snapshot, reducing the friction of re-explaining context after the developer has already made manual changes. Cascade also supports MCP for connecting to external tools, and can browse documentation or the web to ground its answers in current information. Windsurf, and Cascade specifically, entered a crowded field of AI-native or AI-augmented editors (Cursor, Zed, and traditional IDEs adding AI features) competing primarily on the quality and reliability of agentic multi-file editing. Windsurf was acquired by Cognition (maker of the Devin AI software engineer) in 2024, folding Cascade's technology and team into Cognition's broader agentic coding efforts.
Key Features
- Agentic multi-file editing with continuous awareness of live editor state
- Executes terminal commands and iterates based on their output
- 'Flows' concept: synchronized human-AI collaborative editing context
- Configurable autonomy levels from manual approval to automatic execution
- Model Context Protocol (MCP) support for external tool integration
- Codebase search and multi-file context retrieval
- Can browse documentation/the web to ground responses
- Built into the standalone Windsurf editor (a VS Code-compatible fork)
