-### Verify Backend is Running
+### Start Optimization
-```bash
+Launches `run_optimization.py` with configurable options:
-curl http://localhost:8000/health
+- Max iterations
-# Should return: {"status":"healthy"}
+- FEA batch size
+- Tuning trials
+- Ensemble size
+- Patience
+- Fresh start option
 
-curl http://localhost:8000/api/optimization/studies
+### Kill Process
-# Should return: {"studies":[...]}
+Force-kills the optimization process and all child processes:
-```
+- Gets child processes before killing parent
+- Kills children bottom-up
+- Uses SIGKILL for immediate termination
 
-### Test WebSocket Connection
+### Validate Top N
-```bash
+Runs FEA validation on the best N neural network predictions to verify accuracy.

+## Your Role
+You help engineers with structural optimization using NX Nastran simulations. You can:
+1. **Analyze Results** - Interpret optimization progress, identify trends, explain convergence
+2. **Query Data** - Fetch trial data, compare configurations, find best designs
+3. **Modify Settings** - Update design variable bounds, objectives, constraints
+4. **Explain Concepts** - FEA, Zernike polynomials, wavefront error, stress analysis
+5. **Troubleshoot** - Debug failed trials, identify issues, suggest fixes
+
+## Atomizer Context
+- Atomizer uses Optuna for Bayesian optimization
+- Studies can use FEA-only or hybrid FEA/Neural surrogate approaches
+- Results are stored in SQLite databases (study.db)
+- Design variables are NX expressions in CAD models
+- Objectives include stress, displacement, frequency, Zernike WFE
+
+## Guidelines
+- Be concise but thorough
+- Use technical language appropriate for engineers
+- When showing data, format it clearly (tables, lists)
+- If uncertain, say so and suggest how to verify
+- Proactively suggest next steps or insights

-## Executive Summary
-The optimization study successfully converged after 45 trials. The best design achieved a mass reduction of 15% while maintaining all constraints.
-
-## Key Findings
-- **Best Objective Value**: 115.185 Hz
-- **Critical Parameter**: Plate Thickness (sensitivity: 0.85)
-- **Constraint Margins**: All safety factors > 1.2
-
-## Recommendations
-Based on the results, we recommend proceeding with the design from Trial #45. Further refinement could be achieved by narrowing the bounds for 'thickness'.

+# Atomizer Dashboard Improvement Plan
+
+## Executive Summary
+
+This document outlines a comprehensive plan to enhance the Atomizer dashboard into a self-contained, professional optimization platform with integrated AI assistance through Claude Code.
+
+---
+
+## Current State
+
+### Existing Pages
+- **Home** (`/`): Study selection with README preview
+- **Dashboard** (`/dashboard`): Real-time monitoring, charts, control panel
+- **Results** (`/results`): AI-generated report viewer
+
+### Existing Features
+- Study selection with persistence
+- README display on study hover
+- Convergence plot (Plotly)
+- Pareto plot for multi-objective
+- Parallel coordinates
+- Parameter importance chart
+- Console output viewer
+- Control panel (start/stop/validate)
+- Optuna dashboard launch
+- AI report generation
+
+---
+
+## Proposed Improvements
+
+### Phase 1: Core UX Enhancements
+
+#### 1.1 Unified Navigation & Branding
+- **Logo & Brand Identity**: Professional Atomizer logo in sidebar
+- **Breadcrumb Navigation**: Show current path (e.g., `Atomizer > m1_mirror > Dashboard`)
+- **Quick Study Switcher**: Dropdown in header to switch studies without returning to Home
+- **Keyboard Shortcuts**: `Ctrl+K` for command palette, `Ctrl+1/2/3` for page navigation
+
+#### 1.2 Study Overview Card (Home Page Enhancement)
+When a study is selected, show a summary card with:
+- Trial progress ring/chart
+- Best objective value with trend indicator
+- Last activity timestamp
+- Quick action buttons (Start, Validate, Open)
+- Thumbnail preview of convergence
+
+#### 1.3 Real-Time Status Indicators
+- **Global Status Bar**: Shows running processes, current trial, ETA
+- **Live Toast Notifications**: Trial completed, error occurred, validation done
+- **Sound Notifications** (optional): Audio cue on trial completion
+
+#### 1.4 Dark/Light Theme Toggle
+- Persist theme preference in localStorage
+- System theme detection
+
+---
+
+### Phase 2: Advanced Visualization
+
+#### 2.1 Interactive Trial Table
+- Sortable/filterable data grid with all trial data
+- Column visibility toggles
+- Export to CSV/Excel
+- Click row to highlight in plots
+- Filter by FEA vs Neural trials
+
+#### 2.2 Enhanced Charts
+- **Zoomable Convergence**: Brushing to select time ranges

+#### 3.4 Claude Code Capabilities
+
+When integrated, Claude Code will be able to:
+
+| Capability | Description | Example Command |
+|------------|-------------|-----------------|
+| **Analyze Results** | Interpret optimization progress | "Why is my convergence plateauing?" |
+| **Explain Physics** | Describe FEA/Zernike concepts | "Explain astigmatism in my mirror" |
+| **Modify Config** | Update design variables | "Increase the max bounds for whiffle_min to 60" |
+| **Create Studies** | Generate new study from description | "Create a study for my new bracket" |
+| **Query Data** | SQL-like data exploration | "Show me the top 5 trials by stress" |
+| **Generate Code** | Write custom analysis scripts | "Write a Python script to compare trials" |
+| **Debug Issues** | Diagnose optimization problems | "Why did trial 42 fail?" |

+
+3. **Objectives**
+   - Template selection (stress, displacement, frequency, Zernike)
+   - Direction (minimize/maximize)
+   - Target values and weights
+
+4. **Constraints**
+   - Add geometric/physical constraints
+   - Feasibility preview
+
+5. **Algorithm Settings**

+
+### Phase 5: Self-Contained Packaging
+
+#### 5.1 Electron Desktop App
+
+Package the dashboard as a standalone desktop application:
+
+```
+Atomizer.exe
+├── Frontend (React bundled)
+├── Backend (Python bundled with PyInstaller)
+├── NX Integration (optional)
+└── Claude API (requires key)
+```
+
+Benefits:
+- No Node.js/Python installation needed
+- Single installer for users
+- Offline capability (except AI features)
+- Native file dialogs
+- System tray integration
+
+#### 5.2 Docker Deployment
+
+```yaml
+# docker-compose.yml
+version: '3.8'
+services:
+  frontend:
+    build: ./atomizer-dashboard/frontend
+    ports:
+      - "3000:3000"
+
+  backend:
+    build: ./atomizer-dashboard/backend
+    ports:
+      - "8000:8000"
+    volumes:
+      - ./studies:/app/studies
+    environment:
+      - ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY}
+```
+

+## Implementation Priority
+
+| Phase | Feature | Effort | Impact | Priority |
+|-------|---------|--------|--------|----------|
+| 1.1 | Unified Navigation | Medium | High | P1 |
+| 1.2 | Study Overview Card | Low | High | P1 |
+| 1.3 | Real-Time Status | Medium | High | P1 |
+| 2.1 | Interactive Trial Table | Medium | High | P1 |
+| 3.1 | Claude Chat Backend | High | Critical | P1 |
+| 3.3 | Claude Chat Frontend | Medium | Critical | P1 |
+| 2.2 | Enhanced Charts | Medium | Medium | P2 |
+| 2.4 | Design Space Explorer | High | High | P2 |
+| 4.1 | Study Creation Wizard | High | High | P2 |
+| 5.1 | Electron Packaging | High | Medium | P3 |
+

+
+## Technical Requirements
+
+### Dependencies to Add
+
+**Backend:**
+```
+anthropic>=0.18.0  # Claude API
+websockets>=12.0   # Real-time chat
+```
+
+**Frontend:**
+```
+@radix-ui/react-dialog  # Modals
+@radix-ui/react-tabs    # Tab navigation
+cmdk                    # Command palette
+framer-motion           # Animations
+```
+
+### API Keys Required
+
+- `ANTHROPIC_API_KEY`: For Claude Code integration (user provides)
+
+---
+
+## Security Considerations
+
+1. **API Key Storage**: Never store API keys in frontend; use backend proxy
+2. **File Access**: Sandbox Claude's file operations to study directories only
+3. **Command Execution**: Whitelist allowed commands (no arbitrary shell)
+4. **Rate Limiting**: Prevent API abuse through the chat interface
+
+---
+
+## Next Steps
+
+1. Review and approve this plan
+2. Prioritize features based on user needs
+3. Create GitHub issues for each feature
+4. Begin Phase 1 implementation
+5. Set up Claude API integration testing
