+StackOne tools integrate seamlessly with popular AI frameworks. Convert your tools to the appropriate format:
+
+### OpenAI Agents SDK
+
+The [OpenAI Agents SDK](https://openai.github.io/openai-agents-python/) enables building agentic AI apps with lightweight abstractions.
+
+```python
+# Convert to OpenAI Agents format
+openai_agents_tools = tools.to_openai_agents()
+
+# Use with OpenAI Agents
+from agents import Agent, Runner
+agent = Agent(name="Assistant", tools=openai_agents_tools)
+result = Runner.run_sync(agent, "Your query")
+```
+
+### LangChain
+
+```python
+# Convert to LangChain format
+langchain_tools = tools.to_langchain()
+
+# Use with LangChain
+from langchain_openai import ChatOpenAI
+model = ChatOpenAI().bind_tools(langchain_tools)
+```
+
+### OpenAI Functions
+
+```python
+# Convert to OpenAI function format
+openai_tools = tools.to_openai()
+
+# Use with OpenAI client
+import openai
+client = openai.OpenAI()
+client.chat.completions.create(tools=openai_tools, ...)
+```
