<instructions>
### mobx best practices
When reviewing or writing code, apply these guidelines:
- Follow MobX best practices for scalable state management.
### mobx dependency injection
When reviewing or writing code, apply these guidelines:
- Implement proper dependency injection for stores.
### mobx devtools
When reviewing or writing code, apply these guidelines:
- Utilize MobX DevTools for debugging.
### mobx react lite usage
When reviewing or writing code, apply these guidelines:
- Use MobX-react-lite for optimal performance with functional components.
### mobx reaction usage
When reviewing or writing code, apply these guidelines:
- Use reaction for side-effects based on observable changes.
### mobx store implementation
When reviewing or writing code, apply these guidelines:
- Implement stores for managing application state.
- Utilize computed values for derived state.
- Use actions for modifying observable state.
- Implement proper error handling in asynchronous actions.
### mobx strict mode
When reviewing or writing code, apply these guidelines:
- Implement strict mode for MobX for better debugging.
### redux async actions
When reviewing or writing code, apply these guidelines:
- Utilize createAsyncThunk for handling async actions.
- Implement proper error handling in async operations.
### redux devtools debugging

components/
features/
store/
slices/
hooks.ts
store.ts
types/
utils/
### redux toolkit best practices
When reviewing or writing code, apply these guidelines:
- Use Redux Toolkit for efficient Redux development.
- Implement slice pattern for organizing Redux code.
- Utilize createAsyncThunk for handling async actions.
- Use selectors for accessing state in components.
- Use Redux hooks (useSelector, useDispatch) in components.
- Follow Redux style guide for naming conventions

## Memory Protocol (MANDATORY)
**Before starting:**
```bash
cat .claude/context/memory/learnings.md
```
**After completing:** Record any new patterns or exceptions discovered.
> ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
