 ### Compatibility
 
-Scarf reads Hermes's SQLite database (schema v6) and parses CLI output from `hermes status`, `hermes doctor`, `hermes tools`, `hermes sessions`, `hermes gateway`, and `hermes pairing`. Tested and verified against:
+Scarf reads Hermes's SQLite database and parses CLI output from `hermes status`, `hermes doctor`, `hermes tools`, `hermes sessions`, `hermes gateway`, and `hermes pairing`. Automatic schema detection provides backward compatibility with older databases while supporting new features in newer Hermes versions.

+## Project Dashboards
+
+Project Dashboards turn Scarf into a customizable monitoring hub for all your projects. You define a simple JSON file in your project folder describing what to display — stat boxes, charts, tables, progress bars, checklists, rich text, and embedded web views — and Scarf renders it as a live-updating dashboard. Your Hermes agent can generate and maintain these dashboards automatically.
+
+### What You Can Build
+
+- **Development dashboards** — test coverage, build status, open issues, sprint progress
+- **Data project trackers** — pipeline metrics, data quality scores, processing throughput
+- **Deployment monitors** — deploy history tables, uptime stats, error rate charts
+- **Research dashboards** — experiment results, key findings, paper status checklists
+- **Agent activity views** — cron job results, content generation stats, task completion rates
+- **Embedded web apps** — local dev servers, HTML reports, Grafana dashboards, any web-based tool your agent generates
+- **Any project status** — if your agent can measure it, Scarf can display it
+
+### Quick Start
+
+**1. Create the dashboard file**
+
+Create `.scarf/dashboard.json` in any project folder:
+
+```json
+{
+  "version": 1,
+  "title": "My Project",
+  "description": "Project status at a glance",
+  "sections": [
+    {
+      "title": "Overview",
+      "columns": 3,
+      "widgets": [
+        {
+          "type": "stat",
+          "title": "Test Coverage",
+          "value": "87%",
+          "icon": "checkmark.shield",
+          "color": "green",
+          "subtitle": "+2.1% this week"
+        },
+        {
+          "type": "progress",
+          "title": "Sprint Progress",
+          "value": 0.73,
+          "label": "73% complete",
+          "color": "blue"
+        },
+        {
+          "type": "list",
+          "title": "Tasks",
+          "items": [
+            { "text": "Write unit tests", "status": "done" },
+            { "text": "Update API docs", "status": "active" },
+            { "text": "Deploy to prod", "status": "pending" }
+          ]
+        }
+      ]
+    }
+  ]
+}
+```
+
+**2. Register your project**
+
+In Scarf, go to **Projects** in the sidebar and click the **+** button to add your project folder. Or have your agent add it directly to the registry at `~/.hermes/scarf/projects.json`:
+
+```json
+{
+  "projects": [
+    { "name": "my-project", "path": "/Users/you/Developer/my-project" }
+  ]
+}
+```
+
+**3. View in Scarf**
+
+Select your project in the Projects sidebar — the dashboard renders immediately. Scarf watches the file for changes and refreshes automatically whenever the JSON is updated.
+
+### Widget Types
+
+| Type | Description | Key Fields |
+|------|-------------|------------|
+| `stat` | Key metric with large value display | `value`, `icon`, `color`, `subtitle` |
+| `progress` | Progress bar with label | `value` (0.0–1.0), `label`, `color` |
+| `text` | Rich text block | `content`, `format` ("markdown" or "plain") |
+| `table` | Data table with headers | `columns`, `rows` |
+| `chart` | Line, bar, or pie chart | `chartType`, `series` (each with `name`, `color`, `data`) |
+| `list` | Checklist with status indicators | `items` (each with `text`, `status`: done/active/pending) |
+| `webview` | Embedded web browser | `url`, `height` (default 400) |
+
+The `webview` widget embeds a live web browser directly in your dashboard — perfect for displaying local dev servers, HTML reports, or any web-based tool your agent generates.
+
+When a dashboard includes a webview widget, Scarf adds a tabbed interface: **Dashboard** shows your normal widgets, **Site** shows the web content full-canvas with clean margins — using the entire available space in the app. This gives you the best of both worlds: compact metrics at a glance, and a full embedded browser when you need it.
+
+```json
+{
+  "type": "webview",
+  "title": "Project Report",
+  "url": "http://localhost:8000/dashboard",
+  "height": 500
+}
+```
+
+- `url`: Any URL — typically a local server (`http://localhost:...`) or file path
+- `height`: Height in points when displayed as an inline widget card (default: 400). The Site tab always uses full available space regardless of this setting.
+
+**Colors**: red, orange, yellow, green, blue, purple, pink, teal, indigo, mint, brown, gray
+
+**Icons**: Any [SF Symbol](https://developer.apple.com/sf-symbols/) name (e.g., `checkmark.shield`, `cpu`, `doc.text`, `chart.bar`)
+
+### Agent-Generated Dashboards
+
+The real power is letting your Hermes agent build and update dashboards automatically. Add instructions like this to your agent's context:
+
+> Analyze this project and create a `.scarf/dashboard.json` dashboard with relevant metrics and status. Use stat widgets for key numbers, charts for trends, tables for structured data, lists for task tracking, and a webview widget if the project has a local web server or HTML reports. Register the project in `~/.hermes/scarf/projects.json` if not already registered.
+
+Your agent can update the dashboard as part of cron jobs, after builds, or whenever project state changes. Since Scarf watches the file, updates appear in real-time.
+
+### Dashboard Schema Reference
+
+```json
+{
+  "version": 1,
+  "title": "Required — dashboard title",
+  "description": "Optional — subtitle text",
+  "updatedAt": "Optional — ISO 8601 timestamp",
+  "sections": [
+    {
+      "title": "Section Name",
+      "columns": 3,
+      "widgets": [{ "type": "...", "title": "..." }]
+    }
+  ]
+}
+```
+
+Each section defines a grid with 1–4 columns. Widgets flow left-to-right, wrapping to new rows. See [DASHBOARD_SCHEMA.md](scarf/docs/DASHBOARD_SCHEMA.md) for the full schema reference with examples of every widget type.

+# Scarf Project Dashboard Schema
+
+Scarf can render project dashboards from a JSON file. Place a `dashboard.json` file at `.scarf/dashboard.json` in your project root, and register the project in Scarf.
+
+## Registration
+
+Projects are registered in `~/.hermes/scarf/projects.json`:
+
+```json
+{
+  "projects": [
+    { "name": "my-project", "path": "/path/to/my-project" }
+  ]
+}
+```
+
+You can also add projects from the Scarf UI via the Projects section.
+
+## Dashboard File
+
+Create `.scarf/dashboard.json` in your project root:
+
+```json
+{
+  "version": 1,
+  "title": "My Project",

+  "sections": [
+    {
+      "title": "Section Name",
+      "columns": 3,
+      "widgets": []
+    }
+  ]
+}

+  "format": "markdown"
+}
+```
+

+  "rows": [
+    ["Mar 30", "prod", "success"],
+    ["Mar 29", "staging", "success"]
+  ]
+}
+```
+
+### chart — Line, bar, or pie chart
+
+```json
+{
+  "type": "chart",
+  "title": "Tests Over Time",
+  "chartType": "line",
+  "series": [
+    {
+      "name": "Passing",
+      "color": "green",
+      "data": [
+        { "x": "Mon", "y": 142 },
+        { "x": "Tue", "y": 145 }
+      ]
+    }
+  ]
+}
+```
+
+- `chartType`: "line", "bar", or "pie"
+- `series[].color`: Named color (optional)
+- For pie charts, each series becomes a slice
+
+### list — Checklist
+
+```json
+{
+  "type": "list",
+  "title": "TODO Items",
+  "icon": "checklist",
+  "items": [
+    { "text": "Write tests", "status": "done" },
+    { "text": "Update docs", "status": "active" },
+    { "text": "Deploy", "status": "pending" }
+  ]
+}
+```
+

+
+### webview — Embedded web browser
+
+```json
+{
+  "type": "webview",
+  "title": "Project Dashboard",
+  "url": "http://localhost:8000",
+  "height": 500
+}
+```
+
+- `url`: Any URL — local servers, file paths, or remote pages
+- `height`: Height in points (optional, default: 400)
+
+When a dashboard includes a webview widget, Scarf adds a tabbed interface: **Dashboard** shows all normal widgets, **Site** displays the web content full-canvas. The webview widget is automatically filtered out of the Dashboard tab's grid layout.
+
+## Agent Instructions
+
+To have your Hermes agent generate a dashboard, include these instructions:
+
+> Analyze the project and create a `.scarf/dashboard.json` file with relevant metrics,
+> status indicators, and visualizations. Use the Scarf dashboard schema with sections
+> containing stat, progress, text, table, chart, list, and webview widgets. Register the project
+> in `~/.hermes/scarf/projects.json` if not already registered.
+
+The agent can update the dashboard file at any time — Scarf watches for changes and re-renders automatically.
