+      "\n",
+      "PraisonAI is a platform designed to leverage artificial intelligence to enhance personal and business productivity. It typically involves developing AI models that can assist in various tasks, automate processes, and provide insights based on data analysis.\n",
+      "\n",
+      "## Key Features of PraisonAI\n",
+      "\n",
+      "- **Task Automation**: Automates repetitive tasks, allowing users to focus on more strategic activities.\n",
+      "- **Data Insights**: Analyzes large sets of data to provide actionable insights.\n",
+      "- **Natural Language Processing**: Enables users to interact with the AI through natural language, making it user-friendly.\n",
+      "- **Customizable Solutions**: Tailors AI applications to meet specific user needs across various industries.\n",
+      "\n",
+      "# How Do Agents Work in PraisonAI?\n",
+      "\n",
+      "Agents in PraisonAI refer to autonomous or semi-autonomous AI systems that perform designated tasks or functions. Here’s how they typically operate:\n",
+      "\n",
+      "## 1. **Types of Agents**\n",
+      "\n",
+      "- **Reactive Agents**: Respond to the current environment without internal memory. They act solely based on current inputs.\n",
+      "- **Deliberative Agents**: Have a model of their environment, plan their actions, and retain memories of past interactions.\n",
+      "- **Learning Agents**: Improve their performance over time through experience, adapting to new information.\n",
+      "\n",
+      "## 2. **Functionality of Agents**\n",
+      "\n",
+      "- **Task Execution**: Agents can carry out specific tasks as programmed, such as scheduling, data entry, or customer support.\n",
+      "- **Interaction**: They often interact with users through chat interfaces or APIs, providing a seamless user experience.\n",
+      "- **Integration**: Can be integrated with other systems or software to enhance functionality, such as CRM systems, databases, or other AI tools.\n",
+      "- **Continuous Learning**: Agents may utilize machine learning algorithms to adapt and evolve based on user interactions and data received.\n",
+      "\n",
+      "## 3. **Benefits of Using Agents**\n",
+      "\n",
+      "- **Increased Efficiency**: Automate routine tasks to reduce workload.\n",
+      "- **24/7 Availability**: Provide consistent support and functionality without downtime.\n",
+      "- **Scalability**: Easily scale operations by deploying more agents as needed.\n",
+      "- **Data-Driven Decisions**: Use data insights to inform strategy and operations.\n",
+      "\n",

+   cd rag_examples/agentic_rag_gpt5
+   ```
+
+2. **Install dependencies**
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+3. **Set up your OpenAI API key**
+   ```bash
+   export OPENAI_API_KEY="your-api-key-here"
+   ```
+   Or create a `.env` file:
+   ```
+   OPENAI_API_KEY=your-api-key-here
+   ```
+
+4. **Run the application**

+# PraisonAI Example Plugin
+
+This is a template for creating tool plugins for PraisonAI Agents.
+
+## Installation
+
+```bash
+# Install in development mode
+pip install -e .
+
+# Or install from PyPI (after publishing)
+pip install praisonai-example-plugin
+```
+
+## Usage
+
+After installation, tools are automatically discovered:
+
+```python
+from praisonaiagents import Agent
+
+# Use tools by name - they're auto-discovered!
+agent = Agent(
+    name="Assistant",
+    tools=["example_greet", "example_math", "example_reverse"]
+)
+
+# Or import and use directly
+from praisonai_example_plugin import GreetTool, MathTool, reverse_text
+
+agent = Agent(
+    name="Assistant", 
+    tools=[GreetTool(), MathTool(), reverse_text]
+)
+```
+
+## Creating Your Own Plugin
+
+1. **Copy this template**
+2. **Rename the package** in `pyproject.toml` and `src/` directory
+3. **Add your tools** following the patterns in `__init__.py`
+4. **Update entry_points** in `pyproject.toml` to register your tools
+
+### Tool Patterns
+
+**Class-based tool:**
+```python
+from praisonaiagents import BaseTool
+
+class MyTool(BaseTool):
+    name = "my_tool"
+    description = "What this tool does"
+    
+    def run(self, param: str) -> str:
+        return f"Result: {param}"
+```
+
+**Decorator-based tool:**
+```python
+from praisonaiagents import tool
+
+@tool
+def my_function(param: str) -> str:
+    """What this function does."""
+    return f"Result: {param}"
+```
+
+### Registering Tools
+
+In `pyproject.toml`:
+```toml
+[project.entry-points."praisonaiagents.tools"]
+my_tool = "my_package:MyTool"
+my_function = "my_package:my_function"
+```
+
+## Testing
+
+```bash
+pip install -e ".[dev]"
+pytest
+```
+
+## Publishing
+
+```bash
+pip install build twine
+python -m build
+twine upload dist/*
+```

+Prompt Expander Agent Module
+
+This module provides the PromptExpanderAgent class for expanding short prompts
+into detailed, comprehensive prompts for better task execution.
+
+Unlike QueryRewriterAgent (which optimizes queries for search/retrieval),
+PromptExpanderAgent focuses on enriching prompts for task execution.
+
+Supported Expansion Strategies:
+- **BASIC**: Simple expansion with clarity improvements
+- **DETAILED**: Rich expansion with context, constraints, and examples
+- **STRUCTURED**: Expansion with clear structure (task, format, requirements)
+- **CREATIVE**: Expansion with creative flair and vivid language
+- **AUTO**: Automatically selects the best strategy based on prompt analysis
+
+Example:
+    from praisonaiagents import PromptExpanderAgent, ExpandStrategy
+    
+    agent = PromptExpanderAgent(verbose=True)
+    
+    # Basic expansion
+    result = agent.expand("write a movie script in 3 lines")
+    print(result.expanded_prompt)
+    
+    # Detailed expansion
+    result = agent.expand("blog about AI", strategy=ExpandStrategy.DETAILED)
+    print(result.expanded_prompt)
+    
+    # With tools for context gathering
+    from praisonaiagents.tools import internet_search

+Query Rewriter Agent Module
+
+This module provides the QueryRewriterAgent class for transforming user queries
+to improve retrieval quality in RAG applications.
+
+Supported Rewriting Strategies:
+- **BASIC**: Simple rephrasing for clarity and keyword optimization
+- **HYDE**: Hypothetical Document Embeddings - generates a hypothetical answer
+- **STEP_BACK**: Generates higher-level concept questions for complex queries
+- **SUB_QUERIES**: Decomposes multi-part questions into focused sub-queries
+- **MULTI_QUERY**: Generates multiple paraphrased versions for ensemble retrieval
+- **CONTEXTUAL**: Uses conversation history to resolve references and context
+
