+# Understanding CleverAgents CLI Version, Info, and Diagnostics Commands
+
+## Overview
+This guide demonstrates the three essential system information commands in the CleverAgents CLI: `version`, `info`, and `diagnostics`. These commands provide quick access to system metadata, configuration details, and diagnostic information. You'll learn the difference between fast-path and regular command behavior, and how to use these commands for troubleshooting and system verification.
+
+## Prerequisites
+- CleverAgents installed (`pip install cleveragents`)
+- Python 3.12 or higher
+- Access to a terminal or command-line interface
+
+## What You'll Learn
+This example covers:
+- **Version command**: Display the installed CleverAgents version and build information
+- **Info command**: Get comprehensive system and configuration information
+- **Diagnostics command**: Run diagnostic checks and generate detailed system reports
+- **Output formats**: Using JSON, YAML, and plain text output formats
+- **Fast-path behavior**: Understanding when commands use optimized execution paths
+
+## Step-by-Step Walkthrough
+
+### Step 1: Check the CleverAgents Version
+
+The `version` command is the fastest way to verify your CleverAgents installation.
+
+```bash
+$ agents version
+```
+
+**Expected Output:**
+```
+CleverAgents v3.6.0
+Build: 2026-04-19
+Python: 3.13.0
+```
+
+**What's Happening:**
+The `version` command uses a fast-path execution that bypasses full application initialization. It directly reads version metadata from the package and displays it immediately. This is useful for quick verification without waiting for the full CLI to load.
+
+### Step 2: Get Detailed System Information
+
+The `info` command provides comprehensive system and configuration details.
+
+```bash
+$ agents info
+```
+
+**Expected Output:**
+```
+CleverAgents System Information
+================================
+
+Version Information:
+  Version: 3.6.0
+  Build Date: 2026-04-19
+  Python Version: 3.13.0
+  Platform: linux
+
+Installation Details:
+  Installation Path: /usr/local/lib/python3.13/site-packages/cleveragents
+  Configuration Directory: ~/.cleveragents
+  Database Location: ~/.cleveragents/cleveragents.db
+
+System Configuration:
+  Default Actor: anthropic/claude-sonnet-4-20250514
+  Default Project: None
+  Execution Environment: development
+  Log Level: INFO
+
+Feature Flags:
+  A2A Protocol: enabled
+  Container Execution: enabled
+  Cost Budgets: enabled
+  Safety Profiles: enabled
+```
+
+**What's Happening:**
+The `info` command performs a regular initialization of the application to gather comprehensive system information. It reads configuration files, checks the database, and verifies feature availability. This command takes slightly longer than `version` but provides much more detailed information about your system setup.
+
+### Step 3: Get Machine-Readable Version Information (JSON)
+
+For automation and scripting, use the JSON output format with the `version` command.
+
+```bash
+$ agents --format json version
+```
+
+**Expected Output:**
+```json
+{
+  "status": "success",
+  "data": {
+    "version": "3.6.0",
+    "build_date": "2026-04-19",
+    "python_version": "3.13.0",
+    "platform": "linux",
+    "git_commit": "a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6",
+    "git_branch": "main"
+  }
+}
+```
+
+**What's Happening:**
+The `--format json` flag tells CleverAgents to output the response as JSON. This is useful for parsing the output in scripts or integrating with other tools. The JSON envelope includes a status field and a data field containing the actual information.
+
+### Step 4: Get Machine-Readable System Information (JSON)
+
+Get comprehensive system information in JSON format for programmatic access.
+
+```bash
+$ agents --format json info
+```
+
+**Expected Output:**
+```json
+{
+  "status": "success",
+  "data": {
+    "version": {
+      "version": "3.6.0",
+      "build_date": "2026-04-19",
+      "python_version": "3.13.0",
+      "platform": "linux"
+    },
+    "installation": {
+      "installation_path": "/usr/local/lib/python3.13/site-packages/cleveragents",
+      "config_directory": "/home/user/.cleveragents",
+      "database_location": "/home/user/.cleveragents/cleveragents.db"
+    },
+    "configuration": {
+      "default_actor": "anthropic/claude-sonnet-4-20250514",
+      "default_project": null,
+      "execution_environment": "development",
+      "log_level": "INFO"
+    },
+    "features": {
+      "a2a_protocol": true,
+      "container_execution": true,
+      "cost_budgets": true,
+      "safety_profiles": true
+    }
+  }
+}
+```
+
+**What's Happening:**
+The JSON output is structured hierarchically, making it easy to parse and extract specific information. Each section corresponds to a category of system information.
+
+### Step 5: Run System Diagnostics
+
+The `diagnostics` command performs comprehensive system checks and generates a detailed report.
+
+```bash
+$ agents diagnostics
+```
+
+**Expected Output:**
+```

+        }
+      },
+      {
+        "name": "Network Connectivity Check",
+        "status": "passed",
+        "details": {
+          "dns_resolution": "OK",
+          "api_connectivity": "OK",
+          "server_connectivity": "OK"
+        }
+      }
+    ],
+    "summary": {
+      "total_checks": 8,
+      "passed": 8,
+      "failed": 0,
+      "warnings": 0,
+      "status": "HEALTHY"
+    }
+  }
+}
+```
+
+**What's Happening:**
+The JSON format provides structured diagnostic data that can be easily parsed by monitoring systems, dashboards, or automated alerting tools. Each check includes its status and detailed information about what was verified.
+
+### Step 7: Compare Output Formats
+
+You can also use YAML format for human-readable structured output.
+
+```bash
+$ agents --format yaml version
+```
+
+**Expected Output:**
+```yaml
+status: success
+data:
+  version: 3.6.0
+  build_date: '2026-04-19'
+  python_version: 3.13.0
+  platform: linux
+  git_commit: a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6
+  git_branch: main
+```
+
+**What's Happening:**
+YAML format provides a middle ground between plain text and JSON - it's human-readable but also machine-parseable. This is useful when you want structured output but prefer YAML over JSON.
+
+## Understanding Fast-Path vs Regular Command Behavior
+
+### Fast-Path Commands
+The `version` command uses a fast-path execution:
+- **Execution time**: ~50-100ms
+- **Initialization**: Minimal (no database, no configuration loading)
+- **Use case**: Quick version checks, CI/CD pipelines, automated scripts
+- **Reliability**: Very high (no external dependencies)
+
+### Regular Commands
+The `info` and `diagnostics` commands use regular initialization:
+- **Execution time**: ~500-2000ms (depending on system complexity)
+- **Initialization**: Full application startup (database, configuration, registries)
+- **Use case**: Detailed system information, troubleshooting, verification
+- **Reliability**: High (requires working installation)
