he tool should allow farmers to track and manage their agricultural inventory, including seeds, fertilizers, pesticides, tools, and harvest storage.
Core Features to implement in V0:
- 📦 Inventory Dashboard: Display current stock levels with category filters (Seeds, Fertilizers, Tools, etc.)
- ➕ Add/Remove Items: Simple form to input item name, quantity, category, and optional expiry date
- 🔔 Low Stock Alerts: Highlight items below threshold with visual cues
- 📅 Usage Log: Allow users to record daily usage of items
- 📊 Summary View: Show total inventory value and usage trends
UI Requirements:
- Clean, card-based layout consistent with existing dashboard design
- Use icons and color-coded tags for quick visual recognition
- Include a “Start” button on the dashboard card to access the module
Future-ready Notes:
- Structure code to allow easy integration of AI forecasting and voice input in later versions
- Keep data model extensible for batch tracking and community swap features
