+description: Understanding and leveraging tools within the crewAI framework.

+
+## What is a Tool?
+!!! note "Definition"
+    A tool in CrewAI, is a skill, something Agents can use perform tasks, right now those can be tools from the [crewAI Toolkit](https://github.com/joaomdmoura/crewai-tools) and [LangChain Tools](https://python.langchain.com/docs/integrations/tools), those are basically functions that an agent can utilize for various actions, from simple searches to complex interactions with external systems.
+
+## Key Characteristics of Tools
+
+- **Utility**: Designed for specific tasks such as web searching, data analysis, or content generation.
+- **Integration**: Enhance agent capabilities by integrating tools directly into their workflow.
+- **Customizability**: Offers the flexibility to develop custom tools or use existing ones from LangChain's ecosystem.
+
+## Creating your own Tools
+!!! example "Custom Tool Creation"
+    Developers can craft custom tools tailored for their agent’s needs or utilize pre-built options. Here’s how to create one:
+
+```python
+import json
+import requests
+from crewai import Agent
+from langchain.tools import tool
+from unstructured.partition.html import partition_html
+
+class BrowserTools():
+
+	# Anotate the fuction with the tool decorator from LangChain
+	@tool("Scrape website content")
+	def scrape_website(website):
+		# Write logic for the tool.
+		# In this case a function to scrape website content
+		url = f"https://chrome.browserless.io/content?token={config('BROWSERLESS_API_KEY')}"
+		payload = json.dumps({"url": website})
+		headers = {'cache-control': 'no-cache', 'content-type': 'application/json'}
+		response = requests.request("POST", url, headers=headers, data=payload)
+		elements = partition_html(text=response.text)
+		content = "\n\n".join([str(el) for el in elements])
+		return content[:5000]
+
+# Assign the scraping tool to an agent
+agent = Agent(
+	role='Research Analyst',
+	goal='Provide up-to-date market analysis',
+	backstory='An expert analyst with a keen eye for market trends.',
+	tools=[BrowserTools().scrape_website]
+)
+```
+
+## Using LangChain Tools
+!!! info "LangChain Integration"
+    CrewAI seamlessly integrates with LangChain’s comprehensive toolkit. Assigning an existing tool to an agent is straightforward:
+
+```python
+from crewai import Agent
+from langchain.agents import Tool
+from langchain.utilities import GoogleSerperAPIWrapper
+import os
+
+# Setup API keys
+os.environ["OPENAI_API_KEY"] = "Your Key"
+os.environ["SERPER_API_KEY"] = "Your Key"
+
+search = GoogleSerperAPIWrapper()
+
+# Create and assign the search tool to an agent
+serper_tool = Tool(
+  name="Intermediate Answer",
+  func=search.run,
+  description="Useful for search-based queries",
+)
+
+agent = Agent(
+  role='Research Analyst',
+  goal='Provide up-to-date market analysis',
+  backstory='An expert analyst with a keen eye for market trends.',
+  tools=[serper_tool]
+)
+```
+
+## Conclusion
+Tools are crucial for extending the capabilities of CrewAI agents, allowing them to undertake a diverse array of tasks and collaborate efficiently. When building your AI solutions with CrewAI, consider both custom and existing tools to empower your agents and foster a dynamic AI ecosystem.
