VS Code Copilot Development Instructions for TypeScript

You MUST check compilation output before running ANY script or declaring work complete!

1. ALWAYS check the "Core - Build" task output for compilation errors
2. ALWAYS check the "Ext - Build" task output for compilation errors
3. NEVER run tests if there are compilation errors
4. FIX all compilation errors before moving forward

TypeScript compilation steps

Typescript compilation errors can be found by running the "Core - Build" and "Ext - Build" tasks:

• Core - Build: Compiles the main VS Code TypeScript sources
• Ext - Build: Compiles the built-in extensions
• These background tasks may already be running from previous development sessions
• If not already running, start them to get real-time compilation feedback
• The tasks provide incremental compilation, so they will automatically recompile when files change

TypeScript validation steps

• Use scripts/test.sh (or scripts\test.bat on Windows) for unit tests (add --grep <pattern> to filter tests)
• Use scripts/test-integration.sh (or scripts\test-integration.bat on Windows) for integration tests
• Use npm run valid-layers-check to check for layering issues
