 ## Code Quality Rules
 
 - NEVER fail silently - always log errors and make failures visible to users when appropriate.
+- If a composable is used within only one Vue component, keep it in that component file - do NOT create a separate composable file.
+
+## WebR Documentation References
+
+Always reference the official WebR documentation when working with WebR features. Be eager to check and link to relevant sections:
+
+**Official WebR Documentation**: https://docs.r-wasm.org/webr/latest/
+

+
+### Key Principles:
+- Always link to relevant WebR docs when implementing features
+- Use WebR best practices as documented
+- Reference specific API methods and their documentation
+- Show developers this is a proper WebR showcase, not just a demo
+
+## Testing Philosophy
+
+- DON'T test implementation details like "finding messages with specific text" - these are non-tests
+- DON'T test trivial functionality that just confirms code does what it was written to do
+- DO test actual business logic and user-facing behavior that could realistically break
