 # Copilot Instructions for Gerbil
 
-### General Coding
+- **NEVER use console.\* calls** - they are blocked by ESLint. Use `logError()` from `@/utils/node/logging` (main process) or `window.electronAPI.logs.logError()` (renderer)
-
+- Always use absolute imports: `import { X } from '@/components/X'`
-- Follow existing TypeScript/React patterns in the codebase
+- Never add explicit return types to functions - rely on TypeScript inference
-- Maintain consistency with the established project structure
+- Never create tests, docs, or GitHub workflows
-- Use proper TypeScript types (avoid `any` when possible)
+- Move helper functions out of component files into separate utility files
-- Follow the ESLint configuration (includes SonarJS and security rules)
-- Never create tests, docs or github workflows
-- Stop asking me to run the "dev" script to test changes
-- Try to move helper functions from component code to their own separate files to help minimize clutter
-- Always use absolute imports (e.g. `import { MyComponent } from '@/components/MyComponent'`)
-- Never add explicit return types to functions. We want to rely on implicit types as much as possible
-
-### Logging and Error Handling
-
-- **NEVER use console.\* calls** (console.log, console.error, console.warn, etc.) - they are blocked by ESLint
-- **Backend errors**: Use `this.logManager.logError(message, error)` for main process errors
-- **Frontend errors**: Use `window.electronAPI.logs.logError(message, error)` for renderer process errors
-- All errors are logged asynchronously to avoid blocking the event loop
-- Only use console.\* for critical system errors that must appear in terminal (very rare cases)
