+## 2025-02-17 - Enhanced Mode State Management Architecture
+
+### Context
+The current mode management system provides basic functionality for toggling between Plan and Act modes with simple state persistence. However, as the system grows, we need a more robust and feature-rich mode management system that can handle complex state management, mode-specific behaviors, and better integration with other components.
+
+### Decision
+Implement an enhanced mode state management system with the following key components:
+
+1. **Advanced State Management**
+   - Implement mode-specific settings store
+   - Add context preservation between mode switches
+   - Create mode initialization hooks
+   - Add state validation and recovery mechanisms
+
+2. **Event System**
+   - Implement pre/post mode change hooks
+   - Add event queueing system
+   - Create mode-specific event handlers
+   - Support async event processing
+
+3. **Persistence Layer**
+   - Enhanced state file format with versioning
+   - State migration system
+   - Corruption detection and recovery
+   - Mode-specific context preservation
+
+4. **Integration System**
+   - Mode-aware plugin architecture
+   - LSP integration with mode context
+   - Buffer and window layout persistence
+   - Mode-specific UI elements
+
+### Rationale
+- Current system lacks robust state management
+- Need better integration with other components
+- Require more sophisticated event handling
+- Want to support mode-specific behaviors
+- Need better error handling and recovery
+- Desire for mode-specific UI/UX customization
+
+### Implementation
+1. Phase 1: Core State Management
+   - Enhance state persistence
+   - Add validation system
+   - Implement context preservation
+
+2. Phase 2: Event System
+   - Add event hooks
+   - Implement queueing
+   - Create handlers
+
+3. Phase 3: Persistence Layer
+   - Update state format
+   - Add versioning
+   - Implement migration
+
+4. Phase 4: Integration
+   - Plugin integration
+   - LSP integration
+   - UI integration
+
+### Consequences
+**Positive:**
+- More robust state management
+- Better error handling
+- Enhanced user experience
+- More flexible configuration
+- Better integration capabilities
+
+**Negative:**
+- Increased complexity
+- More maintenance overhead
+- Larger codebase
+- More potential failure points
+
+### Status
+- Decision approved
+- Implementation planning in progress
+- Initial architecture documented
+- Ready for code mode implementation
