VS Code Extension Configuration Validation

Domain: VS Code extension development, configuration management, quality assurance
Complexity: Intermediate
Prerequisites: Understanding of VS Code extension manifest (package.json), TypeScript

Problem

VS Code extensions fail at runtime when:

• Configuration keys are updated without being registered in package.json
• Commands are invoked but not declared in manifest
• Views/webviews reference unregistered IDs
• Context keys are set but not documented

These misconfigurations don't cause compile-time errors and only surface when users interact with specific features.

Solution

Systematic validation of VS Code extension manifest against runtime code usage.
