+# 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/*
+```

+## 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"])
+```
+

+    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
+)

+
+```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

+# 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?"
+
+# Use Gemini
+praisonai research --model deep-research-pro "Your research query"
+
+# Rewrite query before research
+praisonai research --query-rewrite "AI trends"
+
+# Rewrite with search tools
+praisonai research --query-rewrite --rewrite-tools "internet_search" "AI trends"
+
+# Use custom tools from file (gathers context before deep research)
+praisonai research --tools tools.py "Your research query"
+praisonai research -t my_tools.py "Your research query"
+
+# Use built-in tools by name (comma-separated)
+praisonai research --tools "internet_search,wiki_search" "Your query"
+praisonai research -t "yfinance,calculator_tools" "Stock analysis query"
+
+# Save output to file (output/research/{query}.md)

+## 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

+    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!
+```
+
