Problem: Windsurf Feels Overwhelming in Week One

Windsurf IDE setup catches most developers off-guard — the AI capabilities are deep, but the defaults don't unlock them. You install it, open a project, and Cascade just… sits there while you wonder why everyone calls it a productivity multiplier.

You'll learn:

How to install and configure Windsurf for your exact stack in under 20 minutes
The three settings that make Cascade actually useful on day one
Workflow habits that separate productive Windsurf users from frustrated ones

Time: 20 min | Difficulty: Beginner

Why This Happens

Windsurf ships with conservative defaults. Cascade, its AI engine, waits for explicit prompts rather than proactively suggesting. The .windsurfrules file — the single biggest productivity lever — is blank until you write it. Most tutorials skip straight to demos and never explain the config layer underneath.

Symptoms:

Cascade gives generic responses that don't match your project's conventions
Multi-file edits feel slow because you're re-explaining context every time
Autocomplete feels no different from VS Code with Copilot

Solution

Step 1: Install Windsurf

Download the latest stable release from codeium.com/windsurf. Windsurf is free to start — the free tier includes 25 Cascade AI flow actions per month. The Pro plan runs $15/month USD and removes the flow action cap.

# macOS — using Homebrew
brew install --cask windsurf

# Ubuntu 22.04+ — download the .deb package
wget https://windsurf-stable.codeiumdata.com/linux-deb/x86_64/windsurf_latest.deb
sudo dpkg -i windsurf_latest.deb

Expected output: Windsurf opens with the welcome screen and prompts you to sign in with a Codeium account.

If it fails:

dpkg: dependency problems → run sudo apt-get install -f to resolve missing libs
macOS Gatekeeper block → go to System Settings → Privacy & Security → Open Anyway

Step 2: Create Your `.windsurfrules` File

This is the highest-leverage config in Windsurf. The .windsurfrules file sits at your project root and tells Cascade your stack, conventions, and boundaries — so you never re-explain them.

Create the file in your project root:

touch .windsurfrules

Paste a template that matches your stack. Here's one for a TypeScript + Node 22 + PostgreSQL project:

# Stack
- Language: TypeScript 5.x (strict mode)
- Runtime: Node 22
- Database: PostgreSQL 16 via Drizzle ORM
- Package manager: pnpm

# Conventions
- Use named exports only — no default exports
- All async functions must handle errors with try/catch
- Use Zod for all runtime validation at API boundaries
- File names: kebab-case (e.g. user-service.ts)

# Off-limits
- Do NOT use any deprecated Node.js APIs
- Do NOT install lodash — use native array/object methods
- Do NOT write raw SQL — always use Drizzle query builder

# Testing
- All new functions need a corresponding test in /tests
- Test runner: Vitest

Cascade reads this file at the start of every session. It cuts the average prompt length in half because you never state the obvious.

If Cascade still ignores your rules:

Rules not loading → close and reopen the project folder; Windsurf re-reads .windsurfrules on workspace open, not on hot-reload

Step 3: Configure Cascade's Context Window

Open the Cascade panel (Cmd+L on macOS, Ctrl+L on Linux/Windows). In the top-right of the panel, click Context and set it to Codebase instead of the default File.

This is the setting most new users miss. In File mode, Cascade only sees the active file. In Codebase mode, it indexes your entire repo with a vector search and pulls relevant files automatically.

For large monorepos (> 50k lines), switch back to File mode for raw speed and use explicit @file references instead:

# In Codebase mode — works great for projects under ~50k lines
"Add input validation to the checkout endpoint"

# In File mode — be explicit for large repos
"@src/api/checkout.ts Add input validation using Zod"

Step 4: Use Cascade Flows for Multi-File Edits

A Cascade Flow is a multi-step AI action that can read, write, and run terminal commands across multiple files in one go. Trigger it with Cmd+Shift+L (macOS) or Ctrl+Shift+L.

The key habit: describe the outcome, not the steps.

# ✅ Outcome-first — Cascade plans the steps
"Add a /health endpoint to the Express server that checks DB connectivity
and returns JSON with status, uptime, and latency in milliseconds"

# ❌ Step-by-step — you're doing Cascade's job
"Open server.ts, add a new route, then open db.ts, export a ping function..."

Cascade will show you a plan before executing. Review it — especially the list of files it intends to modify. If a file looks wrong, click the Edit Plan button before confirming.

Step 5: Set Up Workspace Snippets for Repeated Prompts

Any prompt you type more than twice should become a snippet. Open the command palette (Cmd+Shift+P) → Preferences: Configure User Snippets → select your language.

More practically for Windsurf: save your most-used Cascade prompts as a prompts.md file in your repo:

# Shared Cascade Prompts

## Add a new API endpoint
"Create a new [METHOD] endpoint at /api/[resource] following the pattern in
src/api/users.ts. Include Zod validation, error handling, and a Vitest test."

## Write a Drizzle migration
"Generate a Drizzle migration for [describe schema change]. Use
db/migrations/ folder. Don't modify existing migration files."

## Debug an error
"@[filename] I'm getting [paste error]. Explain root cause and fix it
without changing the public interface."

Copy-paste from this file during sessions. It takes 10 seconds and keeps Cascade output consistent across your team.

Verification

Open a project you know well and run this test prompt in Cascade (Codebase mode):

"What's the entry point of this project and what are the top 3 files
Cascade should know about for daily development?"

You should see: A specific answer naming real files from your codebase — not a generic response about index.js or main.py. If Cascade names real files and explains their role accurately, your context setup is working.

What You Learned

.windsurfrules is your permanent context layer — write it once per project and Cascade respects it every session
Codebase context mode beats File mode for anything under ~50k lines; larger repos need explicit @file references
Outcome-first prompts in Flows produce better multi-file edits than step-by-step instructions
Windsurf's free tier (25 flow actions/month) is enough to evaluate it; Pro at $15/month USD removes that cap

Tested on Windsurf 1.x (stable), Node 22.x, macOS Sequoia 15.3 and Ubuntu 22.04

FAQ

Q: Does Windsurf work offline? A: No. Cascade requires an active internet connection to Codeium's servers. Local model support is not available as of March 2026.

Q: What is the difference between Cascade and standard autocomplete in Windsurf? A: Autocomplete fills single lines or small blocks inline. Cascade is a full AI agent — it reads multiple files, plans multi-step edits, runs terminal commands, and explains its reasoning. They're independent features running simultaneously.

Q: What is the minimum RAM requirement to run Windsurf comfortably? A: 8GB RAM is the minimum; 16GB is recommended for Codebase context mode on larger projects. Windsurf itself uses roughly 400–600MB idle.

Q: Can Windsurf and Cursor be installed on the same machine at the same time? A: Yes. They don't share config files or extensions. You can run both and compare them on the same project without conflict.

Q: Does .windsurfrules get committed to git? A: It can and usually should be — it standardizes AI behavior for your whole team. Add it to .gitignore only if it contains personal preferences you don't want to share.
