+# Package Manager Example
+
+This example demonstrates how to use the PraisonAI package manager for installing and managing Python packages with security defaults.
+
+## Features Demonstrated
+
+- Installing packages with version constraints
+- Listing installed packages
+- Searching for packages on PyPI
+- Managing package index configuration
+- Security features (dependency confusion prevention)
+
+## Quick Start
+
+```bash
+# Run the example
+python package_manager_example.py
+```
+
+## CLI Commands
+
+### Install Packages
+
+```bash
+# Install a package
+praisonai install requests
+
+# Install with version constraint
+praisonai install "requests>=2.28"
+
+# Install multiple packages
+praisonai install requests httpx aiohttp
+
+# Upgrade existing package
+praisonai install requests --upgrade
+
+# JSON output
+praisonai install requests --json
+```
+
+### Uninstall Packages
+
+```bash
+# Uninstall a package
+praisonai uninstall requests
+
+# Uninstall without confirmation
+praisonai uninstall requests --yes
+```
+
+### List Packages
+
+```bash
+# List all installed packages
+praisonai package list
+
+# JSON output
+praisonai package list --json
+```
+
+### Search Packages
+
+```bash
+# Search PyPI
+praisonai package search langchain
+
+# JSON output
+praisonai package search langchain --json
+```
+
+### Index Configuration
+
+```bash
+# Show current index settings
+praisonai package index show --json
+
+# Set custom index
+praisonai package index set https://pypi.mycompany.com/simple
+
+# Reset to PyPI default
+praisonai package index set https://pypi.org/simple
+```
+
+## Security Features
+
+By default, only the primary index (PyPI) is used. Extra indexes are blocked to prevent dependency confusion attacks.
+
+```bash
+# This will FAIL (extra index not allowed by default)
+praisonai install mypackage --extra-index-url https://other.index.com/simple
+
+# Explicitly allow extra index (shows security warning)
+praisonai install mypackage \
+  --extra-index-url https://other.index.com/simple \
+  --allow-extra-index
+```
+
+## Environment Variables
+
+- `PRAISONAI_PACKAGE_INDEX_URL` - Override primary index URL
+- `PIP_INDEX_URL` - Fallback to pip's index URL

 # Recipe Registry Example
 
-This example demonstrates how to use the PraisonAI recipe registry for publishing and pulling recipes.
+This example demonstrates how to use the PraisonAI recipe registry for publishing and pulling recipes via both local filesystem and HTTP server.
 
 ## Features Demonstrated
 
 - Creating a local registry
-- Packing recipes into bundles
-- Publishing recipes to the registry
+- Starting an HTTP registry server
+- Publishing recipes with token authentication
 - Listing and searching recipes
-- Pulling recipes from the registry
+- Pulling recipes from HTTP registry
 
 ## Quick Start
 
 ```bash
-# Run the example
-python registry_example.py
+# Run the HTTP registry example
+python http_registry_example.py
 ```
 
-## CLI Commands

+# Recipe Background Tasks Example
+
+This example demonstrates how to run recipes and agents as background tasks.
+
+## Prerequisites
+
+```bash
+pip install praisonai praisonaiagents
+export OPENAI_API_KEY="your-api-key"
+```
+
+## Python Example
+
+```bash
+python example_background.py
+```
+
+## CLI Examples
+
+### Submit a recipe as background task
+
+```bash
+# Submit recipe to background
+praisonai background submit --recipe my-recipe --input '{"query": "test"}'
+
+# Check status
+praisonai background status <task_id>
+
+# List all tasks
+praisonai background list
+
+# Cancel a task
+praisonai background cancel <task_id>
+
+# Clear completed tasks
+praisonai background clear
+```
+
+### Run recipe with --background flag
+
+```bash
+# Run recipe in background
+praisonai recipe run my-recipe --background
+
+# With input
+praisonai recipe run my-recipe --background --input '{"topic": "AI"}'
+
+# With session ID
+praisonai recipe run my-recipe --background --session-id session_123
+```
+
+## Key Features
+

+# Recipe Scheduler Example
+
+This example demonstrates how to schedule recipes and agents to run periodically.
+
+## Prerequisites
+
+```bash
+pip install praisonai praisonaiagents
+export OPENAI_API_KEY="your-api-key"
+```
+
+## Python Example
+
+```bash
+python example_scheduler.py
+```
+
+Press Ctrl+C to stop the scheduler and see statistics.
+
+## CLI Examples
+
+### Start a scheduler with task
+
+```bash
+# Basic scheduler
+praisonai schedule start news-checker "Check AI news" --interval hourly
+
+# With timeout and budget
+praisonai schedule start reporter "Generate report" \
+    --interval daily \
+    --timeout 300 \
+    --max-cost 1.00
+
+# With max retries
+praisonai schedule start checker "Check updates" \
+    --interval hourly \
+    --max-retries 5
+```
+
+### Start a scheduler with recipe
+
+```bash
+# Schedule a recipe
+praisonai schedule start news-monitor --recipe news-analyzer --interval hourly
+
+# With all options
+praisonai schedule start my-scheduler \
+    --recipe my-recipe \
+    --interval "*/6h" \
+    --timeout 600 \
+    --max-cost 2.00 \
+    --max-retries 3
+```
+
+### Foreground mode (for testing)
+
+```bash
+# Run in foreground (Ctrl+C to stop)
+praisonai schedule "Check news" --interval "*/30s"
+```
+
+### Manage schedulers
+
+```bash
+# List all schedulers
+praisonai schedule list
+
+# View logs
+praisonai schedule logs news-checker --follow
+
+# Show statistics
+praisonai schedule stats news-checker
+
+# Stop a scheduler
+praisonai schedule stop news-checker
+
+# Stop all schedulers
+praisonai schedule stop-all
+
+# Delete a scheduler
+praisonai schedule delete news-checker
+```
+
+### Export scheduler config
+
+```bash
+praisonai schedule save news-checker --output news-checker.yaml
+```
+
+## Interval Formats
+
+| Format | Description |
+|--------|-------------|
+| `hourly` | Every hour |
+| `daily` | Every day |
+| `*/30m` | Every 30 minutes |
+| `*/6h` | Every 6 hours |
+| `*/30s` | Every 30 seconds (for testing) |
+| `3600` | Every 3600 seconds |
+
+## Key Features
+
+- **Periodic Execution**: Run tasks at regular intervals
+- **Retry Logic**: Automatic retries on failure
+- **Cost Budgeting**: Set spending limits
+- **Daemon Mode**: Run in background
+- **Statistics**: Track success rates
+
+## Safe Defaults
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `interval` | hourly | Execution interval |
+| `max_retries` | 3 | Retry attempts |
+| `timeout` | 300 | Timeout per execution |
+| `max_cost` | 1.00 | Budget limit (USD) |

+Package CLI Feature Handler
+
+Provides pip-like CLI commands for package management:
+- install: Install Python packages
+- uninstall: Uninstall Python packages
+- list: List installed packages
+- search: Search packages
+- index: Manage package indexes
+
+All commands use the canonical `praisonai` or `praisonai package` prefix.
+
+Security:
+- Default to single authoritative index (PyPI)
+- Warn loudly about dependency confusion when using extra indexes
+- Require explicit opt-in for extra index fallback

+  install     Install Python packages (shortcut: praisonai install)
+  uninstall   Uninstall Python packages (shortcut: praisonai uninstall)
+  list        List installed packages
+  search      Search for packages
+  index       Manage package indexes
+
+Examples:

+  praisonai install "requests>=2.28" httpx
+  praisonai uninstall requests
+  praisonai package list
+  praisonai package search langchain
+  praisonai package index show
+  praisonai package index set https://my-index.example.com/simple
+
+Options for 'install':
+  --index-url URL       Use custom index URL
+  --extra-index-url URL Add extra index (requires --allow-extra-index)
+  --allow-extra-index   Allow extra index URLs (security risk!)
+  --python PATH         Python interpreter to use
+  --upgrade, -U         Upgrade packages
+  --no-deps             Don't install dependencies
+  --json                Output in JSON format
