+## Component Validation
+
+The key differentiator of viz-platform is the component registry system:
+
+```python
+# Before writing component code
+get_component_props("Button")
+# Returns: all valid props with types, enums, defaults
+
+# After writing code
+validate_component("Button", {"variant": "filled", "color": "blue"})
+# Returns: {valid: true} or {valid: false, errors: [...]}
+```
+
+This prevents common DMC mistakes:
+- Prop typos (`colour` vs `color`)
+- Invalid enum values (`size="large"` vs `size="lg"`)
+- Wrong case (`fullwidth` vs `fullWidth`)
+
+## Example Workflow
+
+```
+/component Button
+# → Shows all Button props with types and defaults
+
+/theme-new corporate
+# → Creates theme with brand colors
+
+/chart bar
+# → Creates bar chart with theme colors
+
+/dashboard sidebar
+# → Creates sidebar layout with filters
+
+/theme-css corporate
+# → Exports theme as CSS for external use
+```
+
+## Cross-Plugin Integration
+
+viz-platform works seamlessly with data-platform:
+
+1. **Load data** with data-platform: `/ingest sales.csv`
+2. **Create chart** with viz-platform: `/chart line` using the data_ref
+3. **Build layout** with viz-platform: `/dashboard` with filters
+4. **Export** complete dashboard structure
+
+## Chart Types

+| Type | Best For |
+|------|----------|
+| `line` | Time series, trends |
+| `bar` | Comparisons, categories |
+| `scatter` | Correlations, distributions |

+| `histogram` | Frequency distributions |
+| `box` | Statistical distributions |
+| `heatmap` | Matrix correlations |
+| `sunburst` | Hierarchical data |
+| `treemap` | Hierarchical proportions |
+
+## Layout Templates

+| Template | Best For |
+|----------|----------|
+| `basic` | Simple dashboards, reports |
+| `sidebar` | Navigation-heavy apps |
+| `tabs` | Multi-page dashboards |
+| `split` | Comparisons, master-detail |

+# Component Check Agent
+
+You are a strict component validation specialist. Your role is to verify Dash Mantine Components are used correctly, preventing runtime errors from invalid props.
+
+## Trigger Conditions
+
+Activate this agent when:
+- Before rendering any DMC component
+- User asks about component props or usage
+- Code review for DMC components
+- Debugging component errors
+
+## Capabilities
+
+- List available DMC components by category
+- Retrieve component prop specifications
+- Validate component configurations
+- Provide actionable error messages
+- Suggest corrections for common mistakes
+
+## Available Tools
+
+### Component Validation
+- `list_components` - List components, optionally by category
+- `get_component_props` - Get detailed prop specifications
+- `validate_component` - Validate a component configuration
+
+## Workflow Guidelines
+
+1. **Before any DMC component usage**:
+   - Call `get_component_props` to understand available props
+   - Verify prop types match expected values
+   - Check enum constraints
+
+2. **After writing component code**:
+   - Extract component name and props
+   - Call `validate_component` with the configuration
+   - Fix any errors before proceeding
+
+3. **When errors occur**:
+   - Identify the invalid prop or value
+   - Provide specific correction
+   - Offer to re-validate after fix
+
+## Validation Strictness
+
+This agent is intentionally strict because:
+- Invalid props cause runtime errors
+- Typos in prop names fail silently
+- Wrong enum values break styling
+- Type mismatches cause crashes
+
+**Always validate before rendering.**
+
+## Error Message Format
+
+Provide clear, actionable errors:
+
+```
+❌ Invalid prop 'colour' for Button. Did you mean 'color'?
+❌ Prop 'size' expects one of ['xs', 'sm', 'md', 'lg', 'xl'], got 'huge'
+⚠️ Prop 'fullwidth' should be 'fullWidth' (camelCase)
+⚠️ Unknown prop 'onClick' - use 'n_clicks' for Dash callbacks
+```
+
+## Component Categories
+
+| Category | Description | Examples |
+|----------|-------------|----------|
+| `inputs` | User input components | Button, TextInput, Select, Checkbox |
+| `navigation` | Navigation elements | NavLink, Tabs, Breadcrumbs |
+| `feedback` | User feedback | Alert, Notification, Progress |
+| `overlays` | Modal/popup elements | Modal, Drawer, Tooltip |
+| `typography` | Text display | Text, Title, Code |
+| `layout` | Structure components | Container, Grid, Stack |
+| `data` | Data display | Table, Badge, Card |
+
+## Common Mistakes
+
+### Prop Name Typos
+```python
+# Wrong
+dmc.Button(colour="blue")  # 'colour' vs 'color'
+
+# Correct
+dmc.Button(color="blue")
+```
+
+### Invalid Enum Values
+```python
+# Wrong
+dmc.Button(size="large")  # 'large' not valid
+
+# Correct
+dmc.Button(size="lg")  # Use 'lg'
+```
+
+### Wrong Case
+```python
+# Wrong
+dmc.Button(fullwidth=True)  # lowercase
+
+# Correct
+dmc.Button(fullWidth=True)  # camelCase
+```
+
+### React vs Dash Props
+```python
+# Wrong (React pattern)
+dmc.Button(onClick=handler)
+
+# Correct (Dash pattern)
+dmc.Button(id="my-button", n_clicks=0)
+# Then use callback with Input("my-button", "n_clicks")
+```
+
+## Example Interactions
+
+**User**: I want to use a Button component
+**Agent**:
+- Uses `get_component_props("Button")`
+- Shows available props with types
+- Explains common usage patterns
+
+**User**: Check this code: `dmc.Button(variant="primary", colour="red")`
+**Agent**:
+- Uses `validate_component`
+- Reports errors:
+  - 'colour' should be 'color'
+  - 'variant' expects ['filled', 'outline', ...], not 'primary'
+- Suggests: `dmc.Button(variant="filled", color="red")`
+
+**User**: What input components are available?
+**Agent**:
+- Uses `list_components(category="inputs")`
+- Lists all input components with brief descriptions
+
+## Integration with Other Agents
+
+When layout-builder or theme-setup create components:
+1. They should call component-check first
+2. Validate all props before finalizing
+3. Ensure theme tokens are valid color references
+
+This creates a validation layer that prevents invalid components from reaching the user's code.

+# Layout Builder Agent
+
+You are a practical dashboard layout specialist. Your role is to help users create well-structured dashboard layouts with proper filtering, grid systems, and responsive design.
+
+## Trigger Conditions
+
+Activate this agent when:
+- User wants to create a dashboard structure
+- User mentions layout, grid, or responsive design
+- User needs filter components for their dashboard
+- User wants to organize dashboard sections
+
+## Capabilities
+
+- Create base layouts (basic, sidebar, tabs, split)
+- Add filter components (dropdowns, date pickers, sliders)
+- Configure responsive grid settings
+- Add content sections
+- Retrieve and inspect layouts
+
+## Available Tools
+
+### Layout Management
+- `layout_create` - Create a new layout structure
+- `layout_add_filter` - Add filter components
+- `layout_set_grid` - Configure grid settings
+- `layout_add_section` - Add content sections
+- `layout_get` - Retrieve layout details
+
+## Workflow Guidelines
+
+1. **Understand the purpose**:
+   - What data will the dashboard display?
+   - Who is the target audience?
+   - What actions do users need to take?
+
+2. **Choose the template**:
+   - Basic: Simple content display
+   - Sidebar: Navigation-heavy dashboards
+   - Tabs: Multi-page or multi-view
+   - Split: Comparison or detail views
+
+3. **Add filters**:
+   - What dimensions can users filter by?
+   - Date ranges? Categories? Search?
+   - Position filters appropriately
+
+4. **Configure the grid**:
+   - How many columns?
+   - Mobile responsiveness?
+   - Spacing between components?
+
+5. **Add sections**:
+   - Group related content
+   - Name sections clearly
+   - Consider visual hierarchy
+
+## Conversation Style
+
+Be practical and suggest common patterns:
+- "For a sales dashboard, I'd recommend a sidebar layout with date range and product category filters at the top."
+- "Since you're comparing metrics, a split-pane layout would work well - left for current period, right for comparison."
+- "A tabbed layout lets you separate overview, details, and settings without overwhelming users."
+
+## Template Reference
+
+### Basic Layout

+If using with data-platform, add this section:
+
+```markdown
+## Data + Visualization Workflow
+
+### Data Loading (data-platform)
+- `/ingest {file}` - Load CSV, Parquet, or JSON
+- `/schema {table}` - View database schema
+- `/profile {data_ref}` - Statistical summary
+
+### Visualization (viz-platform)
+- `/chart {type}` - Create charts from loaded data
+- `/dashboard {template}` - Build dashboard layouts
+
+### Workflow Pattern
+1. Load data: `read_csv("data.csv")` → returns `data_ref`
+2. Create chart: `chart_create(data_ref="data_ref", ...)`
+3. Add to layout: `layout_add_section(chart_ref="...")`
+4. Apply theme: `theme_activate("my-theme")`
+```
+
+## Agent Configuration
+
+### Using theme-setup agent
+
+When user mentions theming or brand colors:
+```markdown
+Use the theme-setup agent for:
+- Creating new themes with brand colors
+- Configuring typography and spacing
+- Exporting themes as CSS
+```
+
+### Using layout-builder agent
+
+When user wants dashboard structure:
+```markdown
+Use the layout-builder agent for:
+- Creating dashboard layouts
+- Adding filter components
+- Configuring responsive grids
+```
+
+### Using component-check agent
+
+For code review and debugging:
+```markdown
+Use the component-check agent for:
+- Validating DMC component usage
+- Fixing prop errors
+- Understanding component APIs
+```
+
+## Example Project CLAUDE.md
+
+```markdown
+# Project: Sales Dashboard
+
+## Tech Stack
+- Backend: FastAPI
+- Frontend: Dash with Mantine Components
+- Data: PostgreSQL + pandas
+
+## Data (data-platform)
+- Database: PostgreSQL with sales data
+- Key tables: orders, customers, products
+
+## Visualization (viz-platform)
+- Theme: corporate (indigo primary, light mode)
+- Layout: sidebar with date and category filters
+- Charts: line (trends), bar (comparisons), pie (breakdown)
+
+### Component Validation
+ALWAYS use component-check before rendering:
+- get_component_props first
+- validate_component after
+
+### Dashboard Structure
+```
+Sidebar: Navigation links
+Header: Title + date range filter
+Main:
+  - Row 1: KPI cards
+  - Row 2: Line chart (sales over time)
+  - Row 3: Bar chart (by category) + Pie chart (by region)
+```
+```
+
+## Troubleshooting
+
+### MCP tools not available
+1. Check venv exists: `ls mcp-servers/viz-platform/.venv/`
+2. Rebuild if needed: `cd mcp-servers/viz-platform && python -m venv .venv && pip install -r requirements.txt`
+3. Restart Claude Code session
+
+### Component validation fails
+1. Check DMC version matches registry
+2. Use `list_components()` to see available components
+3. Verify prop names are camelCase
+
+### Charts not rendering
+1. Verify data_ref exists with `list_data()`
+2. Check column names match data
+3. Validate theme is active

+# Create Chart
+
+Create a Plotly chart with automatic theme token application.
+
+## Usage
+
+```
+/chart {type}
+```
+
+## Arguments
+
+- `type` (required): Chart type - one of: line, bar, scatter, pie, area, histogram, box, heatmap, sunburst, treemap
+
+## Examples
+
+```
+/chart line
+/chart bar
+/chart scatter
+/chart pie
+```
+
+## Tool Mapping
+
+This command uses the `chart_create` MCP tool:
+
+```python
+chart_create(
+    chart_type="line",
+    data_ref="df_sales",          # Reference to loaded DataFrame
+    x="date",                      # X-axis column
+    y="revenue",                   # Y-axis column
+    color=None,                    # Optional: column for color grouping
+    title="Sales Over Time",       # Optional: chart title
+    theme=None                     # Optional: theme name to apply
+)
+```
+
+## Workflow
+
+1. **User invokes**: `/chart line`
+2. **Agent asks**: Which DataFrame to use? (list available with `list_data` from data-platform)
+3. **Agent asks**: Which columns for X and Y axes?
+4. **Agent asks**: Any grouping/color column?
+5. **Agent creates**: Chart with `chart_create` tool
+6. **Agent returns**: Plotly figure JSON ready for rendering
+
+## Chart Types
+
+| Type | Best For |
+|------|----------|
+| `line` | Time series, trends |
+| `bar` | Comparisons, categories |
+| `scatter` | Correlations, distributions |
+| `pie` | Part-to-whole relationships |
+| `area` | Cumulative trends |
+| `histogram` | Frequency distributions |
+| `box` | Statistical distributions |
+| `heatmap` | Matrix correlations |
+| `sunburst` | Hierarchical data |
+| `treemap` | Hierarchical proportions |
+
+## Theme Integration
+
+Charts automatically inherit colors from the active theme:
+- Primary color for main data
+- Color palette for multi-series
+- Font family and sizes
+- Background colors
+
+Override with explicit theme:
+```python
+chart_create(chart_type="bar", ..., theme="my-dark-theme")
+```
+
+## Output
+
+Returns Plotly figure JSON that can be:
+- Rendered in a Dash app
+- Saved as HTML/PNG
+- Embedded in a layout component

+
+## Listing All Components
+
+To see all available components:
+
+```python
+list_components(category=None)  # All components
+list_components(category="inputs")  # Just input components
+```
+
+### Component Categories
+
+| Category | Components |
+|----------|------------|
+| `inputs` | Button, TextInput, Select, Checkbox, Radio, Switch, Slider, etc. |
+| `navigation` | NavLink, Tabs, Breadcrumbs, Pagination, Stepper |
+| `feedback` | Alert, Notification, Progress, Loader, Skeleton |
+| `overlays` | Modal, Drawer, Tooltip, Popover, Menu |
+| `typography` | Text, Title, Code, Blockquote, List |
+| `layout` | Container, Grid, Stack, Group, Space, Divider |
+| `data` | Table, Badge, Card, Paper, Timeline |
+
+## Validating Component Usage
+
+After inspecting props, validate your usage:
+
+```python
+validate_component(
+    component="Button",
+    props={
+        "variant": "filled",
+        "color": "blue",
+        "size": "lg",
+        "children": "Click me"
+    }
+)
+```
+
+Returns:
+```json
+{
+  "valid": true,
+  "errors": [],
+  "warnings": []
+}
+```
+
+Or with errors:
+```json
+{
+  "valid": false,
+  "errors": [
+    "Invalid prop 'colour' for Button. Did you mean 'color'?",
+    "Prop 'size' expects one of ['xs', 'sm', 'md', 'lg', 'xl'], got 'huge'"
+  ],
+  "warnings": [
+    "Prop 'fullwidth' should be 'fullWidth' (camelCase)"
+  ]
+}
+```
+

+description: Interactive setup wizard for viz-platform plugin - configures MCP server and theme preferences
+---
+
+# Viz-Platform Setup Wizard
+
+This command sets up the viz-platform plugin with Dash Mantine Components validation and theming.
+
+## Important Context
+
+- **This command uses Bash, Read, Write, and AskUserQuestion tools** - NOT MCP tools
+- **MCP tools won't work until after setup + session restart**
+- **DMC version detection is automatic** based on installed package
+
+---
+
+## Phase 1: Environment Validation
+
+### Step 1.1: Check Python Version
+
+```bash
+python3 --version
+```
+
+Requires Python 3.10+. If below, stop setup and inform user.
+
+### Step 1.2: Check DMC Installation
+
+```bash
+python3 -c "import dash_mantine_components as dmc; print(f'DMC {dmc.__version__}')" 2>/dev/null || echo "DMC_NOT_INSTALLED"
+```
+
+If DMC is not installed, inform user:
+```
+Dash Mantine Components is not installed. Install it with:
+  pip install dash-mantine-components>=0.14.0
+```
+
+---
+
+## Phase 2: MCP Server Setup
+
+### Step 2.1: Locate Viz-Platform MCP Server
+
+```bash
+# If running from installed marketplace
+ls -la ~/.claude/plugins/marketplaces/leo-claude-mktplace/mcp-servers/viz-platform/ 2>/dev/null || echo "NOT_FOUND_INSTALLED"
+
+# If running from source
+ls -la ~/claude-plugins-work/mcp-servers/viz-platform/ 2>/dev/null || echo "NOT_FOUND_SOURCE"
+```
+
+### Step 2.2: Check Virtual Environment
+
+```bash
+ls -la /path/to/mcp-servers/viz-platform/.venv/bin/python 2>/dev/null && echo "VENV_EXISTS" || echo "VENV_MISSING"
+```
+
+### Step 2.3: Create Virtual Environment (if missing)
+
+```bash
+cd /path/to/mcp-servers/viz-platform && python3 -m venv .venv && source .venv/bin/activate && pip install --upgrade pip && pip install -r requirements.txt && deactivate
+```
+
+---
+
+## Phase 3: Theme Preferences (Optional)
+
+### Step 3.1: Ask About Theme Setup
+
+Use AskUserQuestion:
+- Question: "Do you want to configure a default theme for your projects?"
+- Header: "Theme"
+- Options:
+  - "Yes, set up a custom theme"
+  - "No, use Mantine defaults"
+
+**If user chooses "No":** Skip to Phase 4.
+
+### Step 3.2: Choose Base Theme
+
+Use AskUserQuestion:
+- Question: "Which base color scheme do you prefer?"
+- Header: "Colors"
+- Options:
+  - "Light mode (default)"
+  - "Dark mode"
+  - "System preference (auto)"
+
+### Step 3.3: Choose Primary Color
+
+Use AskUserQuestion:
+- Question: "What primary color should be used for buttons and accents?"
+- Header: "Primary"
+- Options:
+  - "Blue (default)"
+  - "Indigo"
+  - "Violet"
+  - "Other (I'll specify)"
+
+### Step 3.4: Create System Theme Config
+
+```bash
+mkdir -p ~/.config/claude
+cat > ~/.config/claude/viz-platform.env << 'EOF'
+# Viz-Platform Configuration
+# Generated by viz-platform /initial-setup
+
+VIZ_PLATFORM_COLOR_SCHEME=<SELECTED_SCHEME>
+VIZ_PLATFORM_PRIMARY_COLOR=<SELECTED_COLOR>
+EOF
+chmod 600 ~/.config/claude/viz-platform.env
+```
+
+---
+
+## Phase 4: Validation
+
+### Step 4.1: Verify MCP Server
+
+```bash
+cd /path/to/mcp-servers/viz-platform && .venv/bin/python -c "from mcp_server.server import VizPlatformMCPServer; print('MCP Server OK')"
+```
+
+### Step 4.2: Summary
