+### 3. Deep Research Agent
+
+Automated research with real-time streaming, web search, and citations using OpenAI or Gemini Deep Research APIs.
+
+```python
+from praisonaiagents import DeepResearchAgent
+
+# OpenAI Deep Research
+agent = DeepResearchAgent(
+    model="o4-mini-deep-research",  # or "o3-deep-research"
+    verbose=True
+)
+
+result = agent.research("What are the latest AI trends in 2025?")
+print(result.report)
+print(f"Citations: {len(result.citations)}")
+```
+
+```python
+# Gemini Deep Research
+from praisonaiagents import DeepResearchAgent
+
+agent = DeepResearchAgent(
+    model="deep-research-pro",  # Auto-detected as Gemini
+    verbose=True
+)
+
+result = agent.research("Research quantum computing advances")
+print(result.report)
+```
+
+**Features:**
+- 🔍 Multi-provider support (OpenAI, Gemini, LiteLLM)
+- 📡 Real-time streaming with reasoning summaries
+- 📚 Structured citations with URLs
+- 🛠️ Built-in tools: web search, code interpreter, MCP, file search
+- 🔄 Automatic provider detection from model name
+
+### 4. Query Rewriter Agent
+
+Transform user queries to improve RAG retrieval quality using multiple strategies.
+
+```python
+from praisonaiagents import QueryRewriterAgent, RewriteStrategy
+
+agent = QueryRewriterAgent(model="gpt-4o-mini")
+
+# Basic - expands abbreviations, adds context
+result = agent.rewrite("AI trends")
+print(result.primary_query)  # "What are the current trends in Artificial Intelligence?"
+
+# HyDE - generates hypothetical document for semantic matching
+result = agent.rewrite("What is quantum computing?", strategy=RewriteStrategy.HYDE)
+
+# Step-back - generates broader context question
+result = agent.rewrite("GPT-4 vs Claude 3?", strategy=RewriteStrategy.STEP_BACK)
+
+# Sub-queries - decomposes complex questions
+result = agent.rewrite("RAG setup and best embedding models?", strategy=RewriteStrategy.SUB_QUERIES)
+
+# Contextual - resolves references using chat history
+result = agent.rewrite("What about cost?", chat_history=[...])
+```
+
+**Strategies:**
+- **BASIC**: Expand abbreviations, fix typos, add context
+- **HYDE**: Generate hypothetical document for semantic matching
+- **STEP_BACK**: Generate higher-level concept questions
+- **SUB_QUERIES**: Decompose multi-part questions
+- **MULTI_QUERY**: Generate multiple paraphrased versions
+- **CONTEXTUAL**: Resolve references using conversation history
+- **AUTO**: Automatically detect best strategy
+
+### 5. Agent Memory (Zero Dependencies)
+
+Enable persistent memory for agents - works out of the box without any extra packages.
+
+```python
+from praisonaiagents import Agent
+
+# Enable memory with a single parameter
+agent = Agent(
+    name="Personal Assistant",
+    instructions="You are a helpful assistant that remembers user preferences.",
+    memory=True,  # Enables file-based memory (no extra deps!)
+    user_id="user123"  # Isolate memory per user
+)
+
+# Store memories programmatically
+agent.store_memory("User prefers dark mode", memory_type="short_term")
+agent.store_memory("User's name is John", memory_type="long_term", importance=0.9)
+
+# Memory is automatically injected into conversations
+result = agent.start("What do you know about me?")
+# Agent will recall: "Your name is John and you prefer dark mode"
+
+# Memory persists across sessions - create new agent with same user_id
+agent2 = Agent(name="Assistant", memory=True, user_id="user123")
+# agent2 automatically loads all previous memories!
+```
+
+**Memory Types:**
+- **Short-term**: Rolling buffer of recent context (auto-expires)
+- **Long-term**: Persistent important facts (sorted by importance)
+- **Entity**: People, places, organizations with attributes
+- **Episodic**: Date-based interaction history
+
+**Storage Options:**
+| Option | Dependencies | Description |
+|--------|-------------|-------------|
+| `memory=True` | None | File-based JSON storage (default) |
+| `memory="file"` | None | Explicit file-based storage |
+| `memory="sqlite"` | Built-in | SQLite with indexing |
+| `memory="chromadb"` | chromadb | Vector/semantic search |

+## Custom Tools
+
+### Using `@tool` Decorator
+
+```python
+from praisonaiagents import Agent, tool
+
+@tool
+def search(query: str) -> str:
+    """Search the web for information."""
+    return f"Results for: {query}"
+
+@tool
+def calculate(expression: str) -> float:
+    """Evaluate a math expression."""

+
+agent = Agent(
+    instructions="You are a helpful assistant",
+    tools=[search, calculate]
+)
+agent.start("Search for AI news and calculate 15*4")
+```
+
+### Using `BaseTool` Class
+
+```python
+from praisonaiagents import Agent, BaseTool
+
+class WeatherTool(BaseTool):
+    name = "weather"
+    description = "Get current weather for a location"
+    
+    def run(self, location: str) -> str:
+        return f"Weather in {location}: 72°F, Sunny"
+
+agent = Agent(
+    instructions="You are a weather assistant",
+    tools=[WeatherTool()]
+)
+agent.start("What's the weather in Paris?")
+```
+
+### Creating a Tool Package (pip installable)
+
+```toml
+# pyproject.toml
+[project]
+name = "my-praisonai-tools"
+version = "1.0.0"
+dependencies = ["praisonaiagents"]
+
+[project.entry-points."praisonaiagents.tools"]
+my_tool = "my_package:MyTool"
+```
+
+```python
+# my_package/__init__.py
+from praisonaiagents import BaseTool
+
+class MyTool(BaseTool):
+    name = "my_tool"
+    description = "My custom tool"
+    
+    def run(self, param: str) -> str:
+        return f"Result: {param}"
+```
+
+After `pip install`, tools are auto-discovered:
+```python
+agent = Agent(tools=["my_tool"])  # Works automatically!
+```
+
+
+## Prompt Expansion
+
+Expand short prompts into detailed, actionable prompts:
+
+### CLI Usage
+
+```bash
+# Expand a short prompt into detailed prompt
+praisonai "write a movie script in 3 lines" --expand-prompt
+
+# With verbose output
+praisonai "blog about AI" --expand-prompt -v
+
+# With tools for context gathering
+praisonai "latest AI trends" --expand-prompt --expand-tools tools.py
+
+# Combine with query rewrite
+praisonai "AI news" --query-rewrite --expand-prompt
+```
+
+### Programmatic Usage
+
+```python
+from praisonaiagents import PromptExpanderAgent, ExpandStrategy
+
+# Basic usage
+agent = PromptExpanderAgent()
+result = agent.expand("write a movie script in 3 lines")
+print(result.expanded_prompt)
+
+# With specific strategy
+result = agent.expand("blog about AI", strategy=ExpandStrategy.DETAILED)
+
+# Available strategies: BASIC, DETAILED, STRUCTURED, CREATIVE, AUTO
+```
+
+**Key Difference:**
+- `--query-rewrite`: Optimizes queries for **search/retrieval** (RAG)
+- `--expand-prompt`: Expands prompts for **detailed task execution**
+
+
+## Web Search, Web Fetch & Prompt Caching
+
+### CLI Usage
+
+```bash
+# Web Search - Get real-time information
+praisonai "What are the latest AI news today?" --web-search --llm openai/gpt-4o-search-preview
+
+# Web Fetch - Retrieve and analyze URL content (Anthropic only)
+praisonai "Summarize https://docs.praison.ai" --web-fetch --llm anthropic/claude-sonnet-4-20250514
+
+# Prompt Caching - Reduce costs for repeated prompts
+praisonai "Analyze this document..." --prompt-caching --llm anthropic/claude-sonnet-4-20250514
+```
+
+### Programmatic Usage
+
+```python
+from praisonaiagents import Agent
+
+# Web Search
+agent = Agent(
+    instructions="You are a research assistant",
+    llm="openai/gpt-4o-search-preview",
+    web_search=True
+)
+
+# Web Fetch (Anthropic only)
+agent = Agent(
+    instructions="You are a content analyzer",
+    llm="anthropic/claude-sonnet-4-20250514",
+    web_fetch=True
+)
+
+# Prompt Caching
+agent = Agent(
+    instructions="You are an AI assistant..." * 50,  # Long system prompt
+    llm="anthropic/claude-sonnet-4-20250514",
+    prompt_caching=True
+)
+```

-# MCP SSE Server and Client Implementation
+# PraisonAI Agents
 
-This project demonstrates a working pattern for SSE-based MCP (Model Context Protocol) servers and clients. It consists of three main components:
+A powerful Python framework for building AI agents with self-reflection, tool use, and multi-agent orchestration capabilities.
 
-1. **server.py**: An SSE-based MCP server that provides simple tools
-2. **client.py**: A standalone client that connects to the server and uses its tools with Claude
-3. **mcp-sse.py**: A client using praisonaiagents that connects to the server and uses its tools with OpenAI

+from praisonaiagents import Agent
+
+agent = Agent(
+    name="Assistant",
+    instructions="You are a helpful assistant.",
+    model="gpt-4o-mini"
+)
+
+response = agent.chat("What is the capital of France?")
+print(response)
+```
+
+### Agent with Tools
+
+```python
+from praisonaiagents import Agent
+
+def get_weather(city: str) -> str:
+    """Get weather for a city."""
+    return f"Weather in {city}: Sunny, 22°C"
+
+agent = Agent(
+    name="Weather Agent",
+    instructions="You help users check the weather.",
+    tools=[get_weather]
+)
+
+response = agent.chat("What's the weather in Paris?")
+```
+
+### Multi-Agent Workflow
+
+```python
+from praisonaiagents import Agent, Task, PraisonAIAgents
+
+# Define agents
+researcher = Agent(name="Researcher", instructions="Research topics thoroughly")
+writer = Agent(name="Writer", instructions="Write clear, engaging content")
+
+# Define tasks
+research_task = Task(
+    description="Research AI trends in 2025",
+    agent=researcher,
+    expected_output="Research findings"
+)
+
+write_task = Task(
+    description="Write an article based on research",
+    agent=writer,
+    expected_output="Article draft"
+)
+
+# Run workflow
+agents = PraisonAIAgents(agents=[researcher, writer], tasks=[research_task, write_task])
+result = agents.start()
+```
+
+---

+    verbose=True
+)
+
+result = agent.research("What are the latest AI trends?")
+print(result.report)
+print(f"Citations: {len(result.citations)}")
+
+# Gemini Deep Research
+agent = DeepResearchAgent(
+    model="deep-research-pro",  # Auto-detected as Gemini
+    verbose=True
+)
+
+result = agent.research("Research quantum computing advances")
+```
+
+**Features:**

+### 3. QueryRewriterAgent 🆕
+Transform user queries to improve RAG retrieval quality using multiple strategies.
+
+```python
+from praisonaiagents import QueryRewriterAgent, RewriteStrategy
+
+agent = QueryRewriterAgent(model="gpt-4o-mini", verbose=True)
+
+# Basic rewriting - expands abbreviations, adds context
+result = agent.rewrite("AI trends")
+print(result.primary_query)
+# Output: "What are the current trends in Artificial Intelligence (AI)?"
+
+# HyDE - generates hypothetical document for semantic matching
+result = agent.rewrite("What is quantum computing?", strategy=RewriteStrategy.HYDE)
+print(result.hypothetical_document)
+
+# Step-back - generates broader context question
+result = agent.rewrite("Difference between GPT-4 and Claude 3?", strategy=RewriteStrategy.STEP_BACK)
+print(result.step_back_question)
+
+# Sub-queries - decomposes complex questions
+result = agent.rewrite("How to set up RAG and what embedding models to use?", strategy=RewriteStrategy.SUB_QUERIES)
+print(result.sub_queries)
+
+# Contextual - uses chat history to resolve references
+result = agent.rewrite("What about its cost?", strategy=RewriteStrategy.CONTEXTUAL, chat_history=[...])
+```
+

+    instructions="You are an AI assistant analyzing legal documents." * 50,  # Long prompt
+    llm="anthropic/claude-3-5-sonnet-latest",
+    prompt_caching=True
+)
+
+# First call creates cache, subsequent calls use cached tokens
+result = agent.start("Summarize the key terms")
+```
+
+**Supported Providers:**
+- **OpenAI** (`openai/`) - Automatic caching for prompts ≥1024 tokens
+- **Anthropic** (`anthropic/`) - Manual caching with `cache_control`
+- **Bedrock** (`bedrock/`) - All models supporting prompt caching
+- **Deepseek** (`deepseek/`) - Works like OpenAI
+

+
+## Claude Memory Tool (Beta)
+
+Enable Claude to store and retrieve information across conversations.
+
+```python
+from praisonaiagents import Agent
+
+# Enable Claude memory (Anthropic models only)
+agent = Agent(
+    name="Research Assistant",
+    llm="anthropic/claude-sonnet-4-20250514",
+    claude_memory=True
+)
+
+# Claude will automatically:
+# 1. Check /memories directory before tasks
+# 2. Store progress/learnings in files
+# 3. Reference memories in future conversations
+result = agent.start("Research AI trends and remember key findings")
+```
+
+**Features:**
+- File-based persistent memory in `.praison/claude_memory/`
+- Claude autonomously decides what to store/retrieve
+- Supports: view, create, str_replace, insert, delete, rename commands
+- Cross-conversation learning
+
+**Supported Models:** Claude Sonnet 4, Claude Opus 4, Claude Haiku 4.5
+
+---
+
+## Memory (Zero Dependencies)
+
+Enable persistent memory for agents without any extra packages.
+
+```python
+from praisonaiagents import Agent
+
+# Simple: Enable file-based memory (no extra dependencies!)
+agent = Agent(
+    name="Assistant",
+    memory=True  # Uses FileMemory by default
+)
+
+# Store memories
+agent.store_memory("User prefers dark mode", memory_type="short_term")
+agent.store_memory("User's name is John", memory_type="long_term", importance=0.9)
+
+# Get memory context for prompts
+context = agent.get_memory_context(query="What does the user prefer?")
+```
+
+**Memory Types:**
+- **Short-term**: Rolling buffer of recent context (auto-expires)
+- **Long-term**: Persistent important facts
+- **Entity**: People, places, organizations
+- **Episodic**: Date-based interaction history
+
+**Storage Providers:**
+| Provider | Dependencies | Use Case |
+|----------|-------------|----------|
+| `memory=True` or `"file"` | None | Default, zero-config |
+| `"sqlite"` | Built-in | Search, indexing |
+| `"chromadb"` | chromadb | Semantic/vector search |
+| `"mem0"` | mem0ai | Graph memory, cloud |
+
+---
+
+## Guardrails
+
+Add safety checks and validation to agent responses.
+
+```python
+from praisonaiagents import Agent, LLMGuardrail
+
+# LLM-based guardrail
+guardrail = LLMGuardrail(
+    instructions="Ensure responses are professional and accurate"
+)
+
+agent = Agent(
+    name="Safe Agent",
+    guardrail=guardrail
+)
+```
+
+---
+
+## Handoffs
+
+Transfer conversations between agents.
+
+```python
+from praisonaiagents import Agent, handoff
+
+support_agent = Agent(name="Support", instructions="Handle support queries")
+sales_agent = Agent(name="Sales", instructions="Handle sales queries")
+
+# Enable handoffs
+support_agent.handoffs = [handoff(sales_agent, "Transfer to sales")]
+```
+
+---
+
+## Streaming
+
+Real-time streaming responses.
+
+```python
+from praisonaiagents import Agent
+
+agent = Agent(name="Streamer", verbose=True)
+
+# Streaming is automatic with verbose=True
+response = agent.chat("Tell me a story")
+
+# Or use the stream method
+for chunk in agent.stream("Tell me a story"):
+    print(chunk, end="", flush=True)
+```
+
+---
+
+## Async Support
+
+Full async/await support for all operations.
+
+```python
+import asyncio
+from praisonaiagents import Agent
+
+agent = Agent(name="Async Agent")
+
+async def main():
+    response = await agent.achat("Hello!")
+    print(response)
+
+asyncio.run(main())
+```
+
+---
+
+## Telemetry
+
+Built-in telemetry for monitoring and analytics.
+
+```python
+from praisonaiagents import enable_telemetry, disable_telemetry
+
+# Enable full telemetry
+enable_telemetry()
+
+# Disable telemetry
+disable_telemetry()
+```
+
+**Environment Variables:**
+- `PRAISONAI_DISABLE_TELEMETRY=true` - Disable all telemetry
+- `PRAISONAI_PERFORMANCE_MODE=true` - Minimal overhead mode
+- `DO_NOT_TRACK=true` - Respect DNT preference
+
+---
+
+## Supported LLM Providers
+
+PraisonAI Agents works with any LLM provider via LiteLLM:
+
+| Provider | Model Example |
+|----------|---------------|
+| OpenAI | `gpt-4o`, `gpt-4o-mini`, `o1`, `o3` |
+| Anthropic | `claude-3-5-sonnet`, `claude-3-opus` |
+| Google | `gemini-2.0-flash`, `gemini-pro` |
+| Ollama | `ollama/llama3`, `ollama/mistral` |
+| Azure | `azure/gpt-4` |
+| AWS Bedrock | `bedrock/claude-3` |
+| Groq | `groq/llama3-70b` |
+| Together | `together/mixtral-8x7b` |
+
+```python
+# Use any provider
+agent = Agent(model="anthropic/claude-3-5-sonnet")
+agent = Agent(model="ollama/llama3")
+agent = Agent(model="gemini/gemini-2.0-flash")
+```
+
+---
+
+## Configuration
+
+### Environment Variables
 
 ```bash
-python server.py
+# API Keys
+OPENAI_API_KEY=sk-...
+ANTHROPIC_API_KEY=sk-ant-...
+GEMINI_API_KEY=...
+GOOGLE_API_KEY=...
+
+# Logging
+LOGLEVEL=DEBUG  # DEBUG, INFO, WARNING, ERROR
+
+# Telemetry
+PRAISONAI_DISABLE_TELEMETRY=true
 ```
 
-By default, the server runs on 0.0.0.0:8080, but you can customize the host and port:
+---
 
-```bash
-python server.py --host 127.0.0.1 --port 8081
+## Examples
+
+### Research Agent with Citations
+
+```python
+from praisonaiagents import DeepResearchAgent
+
+agent = DeepResearchAgent(
+    model="o4-mini-deep-research",
+    instructions="Provide data-rich insights with citations",
+    verbose=True
+)
+
+result = agent.research("Economic impact of AI on healthcare")
+
+print(result.report)
+for citation in result.citations:
+    print(f"- {citation.title}: {citation.url}")
 ```
 
-### Running the Standalone Client
+### Multi-Agent Research Team
 
-The standalone client uses Claude to interact with the MCP server tools:
+```python
+from praisonaiagents import Agent, Task, PraisonAIAgents
 
-```bash
-# Set your Anthropic API key
-export ANTHROPIC_API_KEY=your_api_key_here
+researcher = Agent(
+    name="Researcher",
+    instructions="Research topics thoroughly",
+    tools=[duckduckgo_search]
+)
 
-# Run the client
-python client.py http://0.0.0.0:8080/sse
+analyst = Agent(
+    name="Analyst", 
+    instructions="Analyze data and provide insights"
+)
+
+writer = Agent(
+    name="Writer",
+    instructions="Write clear reports"
+)
+
+tasks = [
+    Task(description="Research AI trends", agent=researcher),
+    Task(description="Analyze findings", agent=analyst),
+    Task(description="Write report", agent=writer)
+]
+
+team = PraisonAIAgents(agents=[researcher, analyst, writer], tasks=tasks)
+result = team.start()
 ```
 
-You'll see a prompt where you can type queries for Claude to process using the MCP tools.
+### Agent with Memory and Knowledge
 
-### Running the praisonaiagents Client
+```python
+from praisonaiagents import Agent, Memory, Knowledge
 
-The praisonaiagents client uses OpenAI to interact with the MCP server tools:
-
-```bash
-# Set your OpenAI API key
-export OPENAI_API_KEY=your_api_key_here
-
-# Run the client
-python mcp-sse.py
+agent = Agent(
+    name="Smart Assistant",
+    memory=Memory(use_long_term=True),
+    knowledge=Knowledge(sources=["docs/"]),
+    instructions="Help users with their questions using available knowledge"
+)
 ```
 
-This will automatically send a query about the weather in Paris to the agent.
+---
 
-## How It Works
+## API Reference
 
-1. The server exposes MCP tools via an SSE endpoint
-2. Clients connect to this endpoint and discover available tools
-3. When a user makes a query, the client:
-   - For client.py: Uses Claude to determine which tool to call
-   - For mcp-sse.py: Uses OpenAI to determine which tool to call
-4. The client executes the tool call against the server
-5. The result is returned to the user
+### Agent
 
-This pattern allows for decoupled processes where the MCP server can run independently of clients, making it suitable for cloud-native applications.

+# 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

+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
+

+## Plugin System (NEW!)
+
+PraisonAI now supports a plugin system for creating and distributing tools. External developers can create pip-installable tool packages!
+
+### Quick Start
+
+```python
+from praisonaiagents import BaseTool, tool, Agent
+
+# Method 1: Class-based tool
+class WeatherTool(BaseTool):
+    name = "get_weather"
+    description = "Get weather for a location"
+    
+    def run(self, location: str) -> dict:
+        return {"temp": 72, "condition": "sunny"}
+
+# Method 2: Decorator-based tool
+@tool
+def search(query: str) -> list:
+    """Search the web."""
+    return [{"title": "Result", "url": "https://..."}]
+
+# Use with Agent
+agent = Agent(
+    name="Assistant",
+    tools=[WeatherTool(), search]
+)
+```
+
+### Creating a Plugin Package
+
+External developers can create pip-installable plugins:
+
+**1. Create your tool package:**
+```
+praisonai-weather/
+├── pyproject.toml
+├── src/
+│   └── praisonai_weather/
+│       ├── __init__.py
+│       └── tools.py
+```
+
+**2. Define your tool in `tools.py`:**
+```python
+from praisonaiagents import BaseTool
+
+class WeatherTool(BaseTool):
+    name = "weather"
+    description = "Get current weather"
+    
+    def run(self, location: str) -> dict:
+        # Your implementation
+        return {"temp": 72}
+```
+
+**3. Register via entry_points in `pyproject.toml`:**
+```toml
+[project]
+name = "praisonai-weather"
+version = "1.0.0"
+
+[project.entry-points."praisonaiagents.tools"]
+weather = "praisonai_weather.tools:WeatherTool"
+```
+
+**4. Users install and use:**
+```bash
+pip install praisonai-weather
+```
+
+```python
+from praisonaiagents import Agent
+
+# Tool is auto-discovered!
+agent = Agent(tools=["weather"])
+```
+

+MEMORY_SYSTEM_PROMPT = """
+IMPORTANT: ALWAYS VIEW YOUR MEMORY DIRECTORY BEFORE DOING ANYTHING ELSE.
+
+MEMORY PROTOCOL:
+1. Use the `view` command of your `memory` tool to check for earlier progress.
+2. ... (work on the task) ...
+   - As you make progress, record status / progress / thoughts etc in your memory.
+
+ASSUME INTERRUPTION: Your context window might be reset at any moment, so you risk losing any progress that is not recorded in your memory directory.
+
+When editing your memory folder, always try to keep its content up-to-date, coherent and organized. You can rename or delete files that are no longer relevant. Do not create new files unless necessary.

+class ClaudeMemoryTool:
+    """
+    File-based memory tool for Claude models.
+    
+    Implements Anthropic's Memory Tool API (beta). Claude autonomously decides
+    what to store and retrieve from the memory directory.
+    
+    Storage: {base_path}/memories/
+    
+    Commands:
+    - view: Show directory contents or file contents with optional line ranges
+    - create: Create or overwrite a file
+    - str_replace: Replace text in a file
+    - insert: Insert text at a specific line
+    - delete: Delete a file or directory
+    - rename: Rename or move a file/directory
+    
+    Example:
+        ```python
+        from praisonaiagents import Agent
+        from praisonaiagents.tools import ClaudeMemoryTool
+        
+        # Use default storage

+## Using Python Code
+
+Light weight package dedicated for coding:
+```bash
+pip install praisonaiagents
+```
+
+```bash
+export OPENAI_API_KEY=xxxxxxxxxxxxxxxxxxxxxx
+```
+
+### 1. Single Agent
+
+Create app.py file and add the code below:
+```python
+from praisonaiagents import Agent
+agent = Agent(instructions="Your are a helpful AI assistant")
+agent.start("Write a movie script about a robot in Mars")
+```
+
+Run:
+```bash
+python app.py
+```
+
+### 2. Multi Agents
+
+Create app.py file and add the code below:
+```python
+from praisonaiagents import Agent, PraisonAIAgents
+
+research_agent = Agent(instructions="Research about AI")
+summarise_agent = Agent(instructions="Summarise research agent's findings")
+agents = PraisonAIAgents(agents=[research_agent, summarise_agent])
+agents.start()
+```
+
+Run:
+```bash
+python app.py
+```
+
+### 3. Deep Research Agent
+
+Automated research with real-time streaming, web search, and citations using OpenAI or Gemini Deep Research APIs.
+
+```python
+from praisonaiagents import DeepResearchAgent
+
+# OpenAI Deep Research
+agent = DeepResearchAgent(
+    model="o4-mini-deep-research",  # or "o3-deep-research"
+    verbose=True
+)
+
+result = agent.research("What are the latest AI trends in 2025?")
+print(result.report)
+print(f"Citations: {len(result.citations)}")
+```
+
+```python
+# Gemini Deep Research
+from praisonaiagents import DeepResearchAgent
+
+agent = DeepResearchAgent(
+    model="deep-research-pro",  # Auto-detected as Gemini
+    verbose=True
+)
+
+result = agent.research("Research quantum computing advances")
+print(result.report)
+```
+
+**Features:**
+- 🔍 Multi-provider support (OpenAI, Gemini, LiteLLM)
+- 📡 Real-time streaming with reasoning summaries
+- 📚 Structured citations with URLs
+- 🛠️ Built-in tools: web search, code interpreter, MCP, file search
+- 🔄 Automatic provider detection from model name
+
+### 4. Query Rewriter Agent
+
+Transform user queries to improve RAG retrieval quality using multiple strategies.
+
+```python
+from praisonaiagents import QueryRewriterAgent, RewriteStrategy
+
+agent = QueryRewriterAgent(model="gpt-4o-mini")
+
+# Basic - expands abbreviations, adds context
+result = agent.rewrite("AI trends")
+print(result.primary_query)  # "What are the current trends in Artificial Intelligence?"
+
+# HyDE - generates hypothetical document for semantic matching
+result = agent.rewrite("What is quantum computing?", strategy=RewriteStrategy.HYDE)
+
+# Step-back - generates broader context question
+result = agent.rewrite("GPT-4 vs Claude 3?", strategy=RewriteStrategy.STEP_BACK)
+
+# Sub-queries - decomposes complex questions
+result = agent.rewrite("RAG setup and best embedding models?", strategy=RewriteStrategy.SUB_QUERIES)
+
+# Contextual - resolves references using chat history
+result = agent.rewrite("What about cost?", chat_history=[...])
+```
+
+**Strategies:**
+- **BASIC**: Expand abbreviations, fix typos, add context
+- **HYDE**: Generate hypothetical document for semantic matching
+- **STEP_BACK**: Generate higher-level concept questions
+- **SUB_QUERIES**: Decompose multi-part questions
+- **MULTI_QUERY**: Generate multiple paraphrased versions
+- **CONTEXTUAL**: Resolve references using conversation history
+- **AUTO**: Automatically detect best strategy
+
+### 5. Agent Memory (Zero Dependencies)
+
+Enable persistent memory for agents - works out of the box without any extra packages.
+
+```python
+from praisonaiagents import Agent
+
+# Enable memory with a single parameter
+agent = Agent(
+    name="Personal Assistant",
+    instructions="You are a helpful assistant that remembers user preferences.",
+    memory=True,  # Enables file-based memory (no extra deps!)
+    user_id="user123"  # Isolate memory per user
+)
+
+# Store memories programmatically
+agent.store_memory("User prefers dark mode", memory_type="short_term")
+agent.store_memory("User's name is John", memory_type="long_term", importance=0.9)
+
+# Memory is automatically injected into conversations
+result = agent.start("What do you know about me?")
+# Agent will recall: "Your name is John and you prefer dark mode"
+
+# Memory persists across sessions - create new agent with same user_id
+agent2 = Agent(name="Assistant", memory=True, user_id="user123")
+# agent2 automatically loads all previous memories!
+```
+
+**Memory Types:**
+- **Short-term**: Rolling buffer of recent context (auto-expires)
+- **Long-term**: Persistent important facts (sorted by importance)
+- **Entity**: People, places, organizations with attributes
+- **Episodic**: Date-based interaction history
+
+**Storage Options:**
+| Option | Dependencies | Description |
+|--------|-------------|-------------|
+| `memory=True` | None | File-based JSON storage (default) |
+| `memory="file"` | None | Explicit file-based storage |
+| `memory="sqlite"` | Built-in | SQLite with indexing |
+| `memory="chromadb"` | chromadb | Vector/semantic search |
+
+## Using No Code
+
+### Auto Mode:
+```bash
+pip install praisonai
+export OPENAI_API_KEY=xxxxxxxxxxxxxxxxxxxxxx
+praisonai --auto create a movie script about Robots in Mars
+```
+
+### Query Rewriting (works with any command):
+```bash
+# Rewrite query for better results (uses QueryRewriterAgent)
+praisonai "AI trends" --query-rewrite
+
+# Rewrite with search tools (agent decides when to search)
+praisonai "latest developments" --query-rewrite --rewrite-tools "internet_search"
+
+# Works with any prompt
+praisonai "explain quantum computing" --query-rewrite -v
+```
+
+### Deep Research CLI:
+```bash
+# Default: OpenAI (o4-mini-deep-research)
+praisonai research "What are the latest AI trends in 2025?"

+
+
+## Custom Tools
+
+### Using `@tool` Decorator
+
+```python
+from praisonaiagents import Agent, tool
+
+@tool
+def search(query: str) -> str:
+    """Search the web for information."""
+    return f"Results for: {query}"
+
+@tool
+def calculate(expression: str) -> float:
+    """Evaluate a math expression."""
+    return eval(expression)
+
+agent = Agent(
+    instructions="You are a helpful assistant",
+    tools=[search, calculate]
+)
+agent.start("Search for AI news and calculate 15*4")
+```
+
+### Using `BaseTool` Class
+
+```python
+from praisonaiagents import Agent, BaseTool
+
+class WeatherTool(BaseTool):
+    name = "weather"
+    description = "Get current weather for a location"
+    
+    def run(self, location: str) -> str:
+        return f"Weather in {location}: 72°F, Sunny"
+
+agent = Agent(
+    instructions="You are a weather assistant",
+    tools=[WeatherTool()]
+)
+agent.start("What's the weather in Paris?")
+```
+
+### Creating a Tool Package (pip installable)
+
+```toml
+# pyproject.toml
+[project]
+name = "my-praisonai-tools"
+version = "1.0.0"
+dependencies = ["praisonaiagents"]
+
+[project.entry-points."praisonaiagents.tools"]
+my_tool = "my_package:MyTool"
+```
+
+```python
+# my_package/__init__.py
+from praisonaiagents import BaseTool
+
+class MyTool(BaseTool):
+    name = "my_tool"
+    description = "My custom tool"
+    
+    def run(self, param: str) -> str:
+        return f"Result: {param}"
+```
+
+After `pip install`, tools are auto-discovered:
+```python
+agent = Agent(tools=["my_tool"])  # Works automatically!
+```
+
+
+## Prompt Expansion
+
+Expand short prompts into detailed, actionable prompts:
+
+### CLI Usage
+
+```bash
+# Expand a short prompt into detailed prompt
+praisonai "write a movie script in 3 lines" --expand-prompt
+
+# With verbose output
+praisonai "blog about AI" --expand-prompt -v
+
+# With tools for context gathering
+praisonai "latest AI trends" --expand-prompt --expand-tools tools.py
+
+# Combine with query rewrite
+praisonai "AI news" --query-rewrite --expand-prompt
+```
+
+### Programmatic Usage
+
+```python
+from praisonaiagents import PromptExpanderAgent, ExpandStrategy
+
+# Basic usage
+agent = PromptExpanderAgent()
+result = agent.expand("write a movie script in 3 lines")
+print(result.expanded_prompt)
+
+# With specific strategy
+result = agent.expand("blog about AI", strategy=ExpandStrategy.DETAILED)
+
+# Available strategies: BASIC, DETAILED, STRUCTURED, CREATIVE, AUTO
+```
+
+**Key Difference:**
+- `--query-rewrite`: Optimizes queries for **search/retrieval** (RAG)
+- `--expand-prompt`: Expands prompts for **detailed task execution**
+
+
+## Web Search, Web Fetch & Prompt Caching
+
+### CLI Usage
+
+```bash
+# Web Search - Get real-time information
+praisonai "What are the latest AI news today?" --web-search --llm openai/gpt-4o-search-preview
+
+# Web Fetch - Retrieve and analyze URL content (Anthropic only)
+praisonai "Summarize https://docs.praison.ai" --web-fetch --llm anthropic/claude-sonnet-4-20250514
+
+# Prompt Caching - Reduce costs for repeated prompts
+praisonai "Analyze this document..." --prompt-caching --llm anthropic/claude-sonnet-4-20250514
+```
+
+### Programmatic Usage
+
+```python
+from praisonaiagents import Agent
+
+# Web Search
+agent = Agent(
+    instructions="You are a research assistant",
+    llm="openai/gpt-4o-search-preview",

+    instructions="You are a content analyzer",
+    llm="anthropic/claude-sonnet-4-20250514",
+    web_fetch=True
+)
+
+# Prompt Caching
+agent = Agent(
+    instructions="You are an AI assistant..." * 50,  # Long system prompt
+    llm="anthropic/claude-sonnet-4-20250514",
+    prompt_caching=True
