2{
3 // Primary completion
4 "github.copilot.enable": { "*": true },
5
6 // Bootspring for complex tasks
7 "bootspring.enable": true,
8
9 // Disable conflicts
10 "codeium.enable": false // If using Copilot
11}Best Practices#
1. Learn the Shortcuts#
Copilot:
Tab- Accept suggestionEsc- Dismiss suggestionAlt + ]- Next suggestionCtrl + Enter- See all suggestions
Codeium:
Tab- AcceptAlt + \- Manual triggerCtrl + →- Accept word
2. Write Good Comments#
AI tools generate better code from clear comments:
1// Good: Clear intent
2// Calculate the total price including tax and discounts
3// Apply 10% discount for orders over $100
4function calculateTotal(items: Item[]): number {
5
6// Bad: Vague
7// Calculate price
8function calc(items): number {3. Use Chat Effectively#
1Good prompts:
2- "Explain why this function might cause a memory leak"
3- "Refactor this to use the repository pattern"
4- "Add error handling for network failures"
5
6Less effective:
7- "Make this better"
8- "Fix it"4. Review Generated Code#
Always review AI-generated code for:
- Security vulnerabilities
- Edge cases
- Performance issues
- Code style consistency
The Future of AI in VS Code#
By late 2026, expect:
- Deeper IDE integration (not just extensions)
- Better multi-file understanding
- More autonomous capabilities
- Local model options improving
The gap between AI-native IDEs (like Cursor) and VS Code with extensions is narrowing, but VS Code's extension ecosystem remains unmatched.
