-## Plan
+## Plan by Phases
-- Build Python backend to execute kubectl commands and serve API
+
-- Create lightweight JavaScript frontend
+### Phase 1: Prototype
-- Implement context/namespace selection
+- Basic Python backend with kubectl wrapper
-- Add search and list views for pods, nodes, PVCs, etc.
+- Lightweight frontend with context/namespace selectors
-- Add action interfaces (describe, delete, logs, etc.)
+- List pods and nodes
+- Basic describe and delete actions
+
+### Phase 2: Search & Actions
+- Search/filter pods, nodes, PVCs, and other resources
+- Add logs viewer
+- Expand actions: describe, delete, logs, and more
+- Improve error handling and feedback
+
+### Phase 3: Polish & Safety
+- Confirmation dialogs for destructive actions
+- Better UI/UX and responsive layout
+- Optional authentication or access controls
+- Documentation and setup instructions
+
+## Roadmap / Checklist
+
+- [x] Add readme describing kubectl gui plan
+- [ ] Phase 1: Prototype backend and basic frontend
+- [ ] Phase 1: Context and namespace selection
+- [ ] Phase 1: List pods and nodes
+- [ ] Phase 2: Search pods, nodes, PVCs, and others
+- [ ] Phase 2: Describe, delete, and logs actions
+- [ ] Phase 3: Safety confirmations and error handling
+- [ ] Phase 3: UI polish and documentation
+
+## Suggestions
+- Use a lightweight Python framework (e.g., Flask or FastAPI) for the backend
+- Keep frontend vanilla JS or minimal framework to stay lightweight
+- Consider running kubectl via subprocess with proper input validation
+- Add a simple status indicator for kubectl connectivity
