Windsurf Performance Tuning

Overview

Optimize Windsurf (Codeium) AI-assisted development workflows. Focus on Cascade flow configuration, context window management, workspace indexing performance, and efficient use of AI completions to minimize latency.

Prerequisites

• Windsurf IDE installed
• Understanding of Cascade AI flows
• Workspace with codebase indexed
• Familiarity with Windsurf settings

Instructions

Step 1: Optimize Workspace Indexing

// .windsurf/settings.json - Exclude large directories from indexing
{
  "codeium.indexing.excludePatterns": [
    "node_modules/**",
    "dist/**",
    "build/**",
    ".git/**",
    "*.min.js",
    "**/*.map",
    "coverage/**",
    "vendor/**",
    ".next/**"
  ],
  "codeium.indexing.maxFileSize": 1048576,  # 1048576 = configured value
  "codeium.indexing.enableSemanticIndexing": true
}

Step 2: Configure Cascade Flow for Speed

// .windsurf/cascade.json - Tune Cascade behavior
{
  "cascade.contextWindow": {
    "maxFiles": 10,
    "maxTokensPerFile": 2000,  # 2000: 2 seconds in ms
    "preferOpenFiles": true,
    "includeImports": true
  },
  "cascade.suggestions": {
    "debounceMs": 150,
    "maxSuggestions": 3,
    "inlineSuggestionsEnabled": true,
    "multiLineSuggestionsEnabled": true
  },
  "cascade.flows": {
    "preferStreaming": true,
    "timeoutMs": 30000,  # 30000: 30 seconds in ms
    "retryCount": 2
  }
}

Step 3: Efficient Context Management

// .windsurf/context.ts - Define project-specific context rules
// Place in workspace root to help Cascade understand your project

/**
 * @windsurf-context
 * Framework: Next.js 14 with App Router
 * Language: TypeScript strict mode
 * Styling: Tailwind CSS
 * State: Zustand
 * Testing: Vitest + Testing Library
 *
 * Key patterns:
 * - Server Components by default
 * - Client Components marked with 'use client'
 * - API routes in app/api/
 * - Shared types in types/
 */

// Create a .windsurfrules file for persistent context
const WINDSURF_RULES = `
When generating code:
- Use TypeScript strict mode
- Prefer async/await over .then()
- Use named exports, not default
- Add JSDoc comments for public APIs
- Use Tailwind classes, not inline styles
`;

Step 4: Keybinding Optimization for Flow Speed

// keybindings.json - Fast access to Cascade features
[
  {
    "key": "ctrl+shift+k",
    "command": "cascade.openChat",
    "when": "editorTextFocus"
  },
  {
    "key": "ctrl+shift+i",
    "command": "cascade.inlineEdit",
    "when": "editorTextFocus"
  },
  {
    "key": "tab",
    "command": "cascade.acceptSuggestion",
    "when": "cascade.suggestionsVisible"
  },
  {
    "key": "alt+]",
    "command": "cascade.nextSuggestion",
    "when": "cascade.suggestionsVisible"
  }
]

Error Handling

Examples

Project-Specific Rules File

<!-- .windsurfrules -->
# Project Context for AI

## Architecture
- Monorepo with pnpm workspaces
- packages/api - Express REST API
- packages/web - Next.js frontend
- packages/shared - Shared types

## Conventions
- Use zod for runtime validation
- Error responses follow RFC 7807  # 7807 = configured value
- All dates are ISO 8601 UTC  # 8601 = configured value
