Windsurf just dropped GPT-5.2-Codex support and Agent Skills on January 12, 2026—making it one of the hottest AI coding tools in a crowded market. While 84% of developers now use AI tools, most are stuck with glorified autocomplete. Windsurf Cascade offers something genuinely different: autonomous coding that handles multi-file refactoring, repository-wide changes, and complete features without hand-holding. At $15/month (25% cheaper than Cursor’s $20), it’s also the most affordable way to experience agentic AI. Here’s how to get started in under 10 minutes.
What Makes Cascade Different: True Agentic AI
Cascade isn’t another autocomplete tool wearing an “AI” badge. It’s an autonomous agent that understands your entire codebase and acts on it.
Real-Time Awareness: Cascade monitors your terminal commands, file edits, and clipboard activity. No need to repeatedly explain context—just type “continue” and it picks up where you left off. This alone eliminates hours of context-switching overhead every week.
Multi-File Operations: Need to rename a component? Cascade updates the file, all imports across 12 other files, tests, and documentation in one shot. Repository-scale understanding means it sees the ripple effects you might miss.
Autonomous Execution: Cascade handles end-to-end features: scaffold a component, update imports, generate tests, run them. One tutorial showed building a complete word game with GitHub deployment in under 30 minutes. Another developer prompted “create a Swift MacOS app with menu bar and about screen” and got a full project structure instantly.
Tool Calling: Cascade makes up to 20 tool calls per prompt, detecting needed packages and installing them automatically. If a task stops mid-execution, click “continue” and it resumes without losing context.
This is what “agentic AI” actually means: less prompting, more building.
Getting Started: Install and Run Your First Task
Installation is straightforward across all platforms.
macOS: Download from the official site and launch immediately. Minimum requirement: OS X Yosemite.
Windows: Run the installer. Windsurf lands in C:\Program Files\Windsurf or your user’s AppData folder. Minimum: Windows 10.
Linux: Ubuntu 20.04+ or any distro with glibc ≥ 2.28. Platform-specific installers handle the rest.
Onboarding takes 2 minutes:
- Import settings from VS Code or Cursor (or start fresh)
- Choose keybindings (VS Code or Vim)
- Pick a theme
- Create a free account
- Open Cascade and start coding
Your first task: Open Cascade in Code mode and type: “Create a React counter component with increment and decrement buttons.” Watch Cascade generate the component, set up state management, and refine the code. Accept changes with one click. That’s it—you’re using agentic AI.
New in January 2026: GPT-5.2-Codex and Agent Skills
Two major updates dropped 11 days ago, and they matter.
GPT-5.2-Codex Support: OpenAI’s latest model built specifically for agentic coding in large codebases. Windsurf offers four reasoning efforts—low, medium, high, and xhigh. Most tasks run fine on medium. Use xhigh when code quality is non-negotiable and you need deeper reasoning. GPT-5.2-Codex excels at long sessions with complex context, the exact scenario where traditional tools choke.
Agent Skills (Launched January 12): Bundle reference scripts, templates, and checklists into reusable “skills” stored at .windsurf/skills/ in your project. Example: Create a “Django REST API” skill with boilerplate code, security checklists, and testing templates. Cascade invokes skills only when relevant—no prompt pollution. This aligns with the broader industry standard, meaning skills can work across multiple AI tools.
Both features position Windsurf at the bleeding edge of agentic development. If you’re evaluating AI coding tools in 2026, these updates are why Windsurf belongs on your shortlist.
Code Mode vs Chat Mode: When to Use Each
Windsurf offers two modes, and knowing when to use each matters.
Code Mode (Your Default): Use this for building features, refactoring, and fixing bugs. Code mode creates and modifies your codebase directly. Prompt: “Refactor this function to use async/await”—Cascade edits the files immediately.
Chat Mode (For Exploration): Use this when learning, debugging, or making architectural decisions. Chat mode answers questions and suggests code you can choose to insert. Prompt: “Why is this React component re-rendering unnecessarily?”—Cascade explains the issue and offers solutions.
Pro tip: Switch modes with a keyboard shortcut. Use Chat for understanding, Code for implementation. Most beginners over-rely on Chat mode when Code mode would be faster.
Practical Tips: Checkpoints, Rules, and Avoiding Pitfalls
Use Checkpoints Before Big Refactors: Create named snapshots of your project state. If a multi-file change goes sideways, revert with one click. Reverts are irreversible, so checkpoint often.
Let Cascade Continue: Don’t repeat yourself. Cascade’s real-time awareness means you can just say “continue” instead of re-explaining context. This feels weird at first—then you never go back.
Enable Automatic Linting: Cascade auto-fixes lint errors it generates and gives you credit discounts when it does. Free bug fixes? Yes.
Custom Rules Save Time: Define your coding style preferences once (indentation, naming conventions, library choices). Cascade remembers forever. Think of it as a living style guide.
Common pitfalls: Don’t over-prompt (Cascade already has context). Don’t default to Chat mode when Code mode is faster. Don’t manually load context—let automatic handling do the work.
Windsurf vs Cursor vs VS Code: The Honest Comparison
Here’s the truth about when to choose Windsurf.
| Feature | Windsurf | Cursor | VS Code + Copilot |
|---|---|---|---|
| Price | $15/month | $20/month | $10/month |
| Context Handling | Automatic (200K tokens) | Manual (10-50K tokens) | Limited |
| Speed | 950 tokens/sec | Slower | Slower |
| Agentic Features | Built-in Cascade | Composer | Basic autocomplete |
| Best For | Beginners, budget users | Production code | Simple completions |
Choose Windsurf if:
- You’re learning to code or new to AI tools (automatic context beats manual wrangling)
- Budget matters ($15 vs $20 is 25% savings)
- You want true agentic coding for multi-file, multi-step tasks
- You use non-VS Code IDEs (Windsurf has 40+ IDE plugins)
Choose Cursor if:
- You need the highest code quality for production systems
- You want access to all frontier models including Claude 4
- You prefer manual control over context
Choose VS Code + Copilot if:
- You only need basic autocomplete, not agentic features
The honest take: Windsurf wins on cost and ease of use. Cursor wins on code quality for complex projects. Both beat VS Code for anything beyond autocomplete.
Why Windsurf Matters in 2026
Agentic AI coding is the dominant trend this year, and Windsurf nails the core promise: less time prompting, more time building. The GPT-5.2-Codex integration and Agent Skills launch show Windsurf isn’t standing still—it’s pushing the frontier.
At $15/month, there’s no reason not to try it. Install takes 5 minutes, first task takes another 5. If you’re still hand-coding everything an AI agent could handle, you’re working harder than necessary.
Try Windsurf Cascade. Let the agent handle the tedious parts. Get back to solving real problems.
