Usage Dashboard

The Usage Dashboard (src/renderer/components/UsageDashboard/) provides analytics and visualizations for AI agent usage.

Architecture

src/renderer/components/UsageDashboard/
├── UsageDashboardModal.tsx      # Main modal with view tabs (Overview, Agents, Activity, AutoRun)
├── SummaryCards.tsx             # Metric cards (queries, duration, cost, Auto Runs)
├── AgentComparisonChart.tsx     # Bar chart comparing agent usage
├── SourceDistributionChart.tsx  # Pie chart for user vs auto queries
├── ActivityHeatmap.tsx          # Weekly activity heatmap (GitHub-style)
├── DurationTrendsChart.tsx      # Line chart for duration over time
├── AutoRunStats.tsx             # Auto Run-specific statistics
├── ChartSkeletons.tsx           # Loading skeleton components
├── ChartErrorBoundary.tsx       # Error boundary with retry
└── EmptyState.tsx               # Empty state when no data

Backend Components

src/main/
├── stats-db.ts                  # SQLite database (better-sqlite3) with WAL mode
│   ├── query_events table       # AI queries with duration, tokens, cost
│   ├── auto_run_sessions table  # Auto Run session tracking
│   ├── auto_run_tasks table     # Individual task tracking
│   └── _migrations table        # Schema migration tracking
├── ipc/handlers/stats.ts        # IPC handlers for stats operations
└── utils/statsCache.ts          # Query result caching

Key Patterns

Real-time Updates:

// Backend broadcasts after each database write
mainWindow?.webContents.send('stats:updated');

// Frontend subscribes with debouncing
useEffect(() => {
	const unsubscribe = window.maestro.stats.onStatsUpdated(() => {
		debouncedRefresh();
	});
	return () => unsubscribe?.();
}, []);

Colorblind-Friendly Palettes:

import { COLORBLIND_AGENT_PALETTE, getColorBlindAgentColor } from '../constants/colorblindPalettes';
// Wong-based palette with high contrast for accessibility

Chart Error Boundaries:

<ChartErrorBoundary chartName="Agent Comparison" onRetry={handleRetry}>
  <AgentComparisonChart data={data} colorBlindMode={colorBlindMode} />
</ChartErrorBoundary>

Related Settings

// In useSettings.ts
statsCollectionEnabled: boolean; // Enable/disable stats collection (default: true)
defaultStatsTimeRange: 'day' | 'week' | 'month' | 'year' | 'all'; // Default time filter
colorBlindMode: boolean; // Use accessible color palettes
preventSleepEnabled: boolean; // Prevent system sleep while agents are busy (default: false)

Document Graph

The Document Graph (src/renderer/components/DocumentGraph/) visualizes markdown file relationships and wiki-link connections using React Flow.

Architecture

src/renderer/components/DocumentGraph/
├── DocumentGraphView.tsx        # Main modal with React Flow canvas
├── DocumentNode.tsx             # Document file node component
├── ExternalLinkNode.tsx         # External URL domain node
├── NodeContextMenu.tsx          # Right-click context menu
├── NodeBreadcrumb.tsx           # Path breadcrumb for selected node
├── GraphLegend.tsx              # Collapsible legend explaining node/edge types
├── graphDataBuilder.ts          # Scans directory, extracts links, builds graph data
└── layoutAlgorithms.ts          # Force-directed and hierarchical layout algorithms

src/renderer/utils/
├── markdownLinkParser.ts        # Parses [[wiki-links]] and [markdown](links)
└── documentStats.ts             # Computes document statistics (word count, etc.)

src/main/ipc/handlers/
└── documentGraph.ts             # Chokidar file watcher for real-time updates

Key Patterns

Building Graph Data:

import { buildGraphData } from './graphDataBuilder';
const { nodes, edges, stats } = await buildGraphData(
	rootPath,
	showExternalLinks,
	maxNodes,
	offset,
	progressCallback
);

Layout Algorithms:

import {
	applyForceLayout,
	applyHierarchicalLayout,
	animateLayoutTransition,
} from './layoutAlgorithms';
const positionedNodes =
	layoutMode === 'force' ? applyForceLayout(nodes, edges) : applyHierarchicalLayout(nodes, edges);
animateLayoutTransition(currentNodes, positionedNodes, setNodes, savePositions);

Node Animation (additions/removals):

import { diffNodes, animateNodesEntering, animateNodesExiting } from './layoutAlgorithms';
const { added, removed, stable } = diffNodes(previousNodes, newNodes);
animateNodesExiting(removed, () => animateNodesEntering(added));

Real-time File Watching:

// Backend watches for .md file changes
window.maestro.documentGraph.watchFolder(rootPath);
window.maestro.documentGraph.onFilesChanged((changes) => {
	debouncedRebuildGraph();
});
// Cleanup on modal close
window.maestro.documentGraph.unwatchFolder(rootPath);

Keyboard Navigation:

// Arrow keys navigate to connected nodes (spatial detection)
// Enter opens selected node
// Tab cycles through connected nodes
// Escape closes modal

Large File Handling

Files over 1MB are truncated to first 100KB for link extraction to prevent UI blocking:

const LARGE_FILE_THRESHOLD = 1 * 1024 * 1024; // 1MB
const LARGE_FILE_PARSE_LIMIT = 100 * 1024; // 100KB

Pagination

Default limit of 50 nodes with "Load more" for large directories:

const DEFAULT_MAX_NODES = 50;
const LOAD_MORE_INCREMENT = 25;

Related Settings

// In useSettings.ts
documentGraphShowExternalLinks: boolean; // Show external link nodes (default: false)
documentGraphMaxNodes: number; // Initial pagination limit (50-1000, default: 50)
