 ### Different Ways to Kick Off a Crew
 
-Once your crew is assembled, initiate the workflow with the appropriate kickoff method. CrewAI provides several methods for better control over the kickoff process: `kickoff()`, `kickoff_for_each()`, `kickoff_async()`, and `kickoff_for_each_async()`.
+Once your crew is assembled, initiate the workflow with the appropriate kickoff method. CrewAI provides several methods for better control over the kickoff process.
+
+#### Synchronous Methods
 
 - `kickoff()`: Starts the execution process according to the defined process flow.
 - `kickoff_for_each()`: Executes tasks sequentially for each provided input event or item in the collection.
-- `kickoff_async()`: Initiates the workflow asynchronously.
-- `kickoff_for_each_async()`: Executes tasks concurrently for each provided input event or item, leveraging asynchronous processing.
+
+#### Asynchronous Methods
+
+CrewAI offers two approaches for async execution:
+
+| Method | Type | Description |
+|--------|------|-------------|
+| `akickoff()` | Native async | True async/await throughout the entire execution chain |
+| `akickoff_for_each()` | Native async | Native async execution for each input in a list |
+| `kickoff_async()` | Thread-based | Wraps synchronous execution in `asyncio.to_thread` |
+| `kickoff_for_each_async()` | Thread-based | Thread-based async for each input in a list |
+
+<Note>
+For high-concurrency workloads, `akickoff()` and `akickoff_for_each()` are recommended as they use native async for task execution, memory operations, and knowledge retrieval.

-## Potential Use Cases
-
-- **Parallel Content Generation**: Kickoff multiple independent crews asynchronously, each responsible for generating content on different topics. For example, one crew might research and draft an article on AI trends, while another crew generates social media posts about a new product launch. Each crew operates independently, allowing content production to scale efficiently.
-
-- **Concurrent Market Research Tasks**: Launch multiple crews asynchronously to conduct market research in parallel. One crew might analyze industry trends, while another examines competitor strategies, and yet another evaluates consumer sentiment. Each crew independently completes its task, enabling faster and more comprehensive insights.

+title: Merge Agent Handler Tool
+description: Enables CrewAI agents to securely access third-party integrations like Linear, GitHub, Slack, and more through Merge's Agent Handler platform
+icon: diagram-project
+mode: "wide"
+---
+
+# `MergeAgentHandlerTool`
+
+The `MergeAgentHandlerTool` enables CrewAI agents to securely access third-party integrations through [Merge's Agent Handler](https://www.merge.dev/products/merge-agent-handler) platform. Agent Handler provides pre-built, secure connectors to popular tools like Linear, GitHub, Slack, Notion, and hundreds more—all with built-in authentication, permissions, and monitoring.
+
+## Installation
+
+```bash
+uv pip install 'crewai[tools]'
+```
+
+## Requirements
+
+- Merge Agent Handler account with a configured Tool Pack
+- Agent Handler API key
+- At least one registered user linked to your Tool Pack
+- Third-party integrations configured in your Tool Pack
+
+## Getting Started with Agent Handler
+
+1. **Sign up** for a Merge Agent Handler account at [ah.merge.dev/signup](https://ah.merge.dev/signup)
+2. **Create a Tool Pack** and configure the integrations you need
+3. **Register users** who will authenticate with the third-party services
+4. **Get your API key** from the Agent Handler dashboard
+5. **Set environment variable**: `export AGENT_HANDLER_API_KEY='your-key-here'`
+6. **Start building** with the MergeAgentHandlerTool in CrewAI
+
+## Notes
+
+- Tool Pack IDs and Registered User IDs can be found in your Agent Handler dashboard or created via API
+- The tool uses the Model Context Protocol (MCP) for communication with Agent Handler
+- Session IDs are automatically generated but can be customized for context persistence
+- All tool calls are logged and auditable through the Agent Handler platform
+- Tool parameters are dynamically discovered from the Agent Handler API and validated automatically
+
+## Usage
+
+### Single Tool Usage
+
+Here's how to use a specific tool from your Tool Pack:
+
+```python {2, 4-9}
+from crewai import Agent, Task, Crew
+from crewai_tools import MergeAgentHandlerTool
+
+# Create a tool for Linear issue creation
+linear_create_tool = MergeAgentHandlerTool.from_tool_name(
+    tool_name="linear__create_issue",
+    tool_pack_id="134e0111-0f67-44f6-98f0-597000290bb3",
+    registered_user_id="91b2b905-e866-40c8-8be2-efe53827a0aa"
+)
+
+# Create a CrewAI agent that uses the tool
+project_manager = Agent(
+    role='Project Manager',
+    goal='Manage project tasks and issues efficiently',
+    backstory='I am an expert at tracking project work and creating actionable tasks.',
+    tools=[linear_create_tool],
+    verbose=True
+)
+
+# Create a task for the agent
+create_issue_task = Task(
+    description="Create a new high-priority issue in Linear titled 'Implement user authentication' with a detailed description of the requirements.",
+    agent=project_manager,
+    expected_output="Confirmation that the issue was created with its ID"
+)
+
+# Create a crew with the agent
+crew = Crew(
+    agents=[project_manager],
+    tasks=[create_issue_task],
+    verbose=True
+)
+
+# Run the crew
+result = crew.kickoff()
+print(result)
+```
+
+### Loading Multiple Tools from a Tool Pack
+
+You can load all available tools from your Tool Pack at once:
+
+```python {2, 4-8}
+from crewai import Agent, Task, Crew
+from crewai_tools import MergeAgentHandlerTool
+
+# Load all tools from the Tool Pack
+tools = MergeAgentHandlerTool.from_tool_pack(

+title: 스트리밍 Crew 실행
+description: CrewAI crew 실행에서 실시간 출력을 스트리밍하기
+icon: wave-pulse
+mode: "wide"
+---
+
+## 소개
+
+CrewAI는 crew 실행 중 실시간 출력을 스트리밍하는 기능을 제공하여, 전체 프로세스가 완료될 때까지 기다리지 않고 결과가 생성되는 대로 표시할 수 있습니다. 이 기능은 대화형 애플리케이션을 구축하거나, 사용자 피드백을 제공하거나, 장시간 실행되는 프로세스를 모니터링할 때 특히 유용합니다.
+
+## 스트리밍 작동 방식
+
+스트리밍이 활성화되면 CrewAI는 LLM 응답과 도구 호출을 실시간으로 캡처하여, 어떤 task와 agent가 실행 중인지에 대한 컨텍스트를 포함한 구조화된 청크로 패키징합니다. 이러한 청크를 실시간으로 반복 처리하고 실행이 완료되면 최종 결과에 접근할 수 있습니다.
+
+## 스트리밍 활성화
+
+스트리밍을 활성화하려면 crew를 생성할 때 `stream` 파라미터를 `True`로 설정하세요:
+
+```python Code
+from crewai import Agent, Crew, Task
+
+# 에이전트와 태스크 생성
+researcher = Agent(
+    role="Research Analyst",
+    goal="Gather comprehensive information on topics",
+    backstory="You are an experienced researcher with excellent analytical skills.",
+)
+
+task = Task(
+    description="Research the latest developments in AI",
+    expected_output="A detailed report on recent AI advancements",
+    agent=researcher,
+)
+
+# 스트리밍 활성화
+crew = Crew(
+    agents=[researcher],
+    tasks=[task],
+    stream=True  # 스트리밍 출력 활성화
+)
+```
+
+## 동기 스트리밍
+
+스트리밍이 활성화된 crew에서 `kickoff()`를 호출하면, 청크가 도착할 때마다 반복 처리할 수 있는 `CrewStreamingOutput` 객체가 반환됩니다:
+
+```python Code
+# 스트리밍 실행 시작
+streaming = crew.kickoff(inputs={"topic": "artificial intelligence"})
+
+# 청크가 도착할 때마다 반복
+for chunk in streaming:
+    print(chunk.content, end="", flush=True)
+
+# 스트리밍 완료 후 최종 결과 접근
+result = streaming.result
+print(f"\n\n최종 출력: {result.raw}")
+```
+
+### 스트림 청크 정보
+
+각 청크는 실행에 대한 풍부한 컨텍스트를 제공합니다:
+
+```python Code
+streaming = crew.kickoff(inputs={"topic": "AI"})
+
+for chunk in streaming:
+    print(f"Task: {chunk.task_name} (인덱스 {chunk.task_index})")
+    print(f"Agent: {chunk.agent_role}")
+    print(f"Content: {chunk.content}")
+    print(f"Type: {chunk.chunk_type}")  # TEXT 또는 TOOL_CALL
+    if chunk.tool_call:
+        print(f"Tool: {chunk.tool_call.tool_name}")
+        print(f"Arguments: {chunk.tool_call.arguments}")
+```
+
+### 스트리밍 결과 접근
+
+`CrewStreamingOutput` 객체는 여러 유용한 속성을 제공합니다:
+
+```python Code
+streaming = crew.kickoff(inputs={"topic": "AI"})
+
+# 청크 반복 및 수집
+for chunk in streaming:
+    print(chunk.content, end="", flush=True)
+
+# 반복 완료 후
+print(f"\n완료됨: {streaming.is_completed}")
+print(f"전체 텍스트: {streaming.get_full_text()}")
+print(f"전체 청크 수: {len(streaming.chunks)}")
+print(f"최종 결과: {streaming.result.raw}")
+```
+
+## 비동기 스트리밍
+
+비동기 애플리케이션의 경우, 비동기 반복과 함께 `akickoff()`(네이티브 async) 또는 `kickoff_async()`(스레드 기반)를 사용할 수 있습니다:
+
+### `akickoff()`를 사용한 네이티브 Async
+
+`akickoff()` 메서드는 전체 체인에서 진정한 네이티브 async 실행을 제공합니다:
+
+```python Code
+import asyncio
+
+async def stream_crew():
+    crew = Crew(
+        agents=[researcher],
+        tasks=[task],
+        stream=True
+    )
+
+    # 네이티브 async 스트리밍 시작
+    streaming = await crew.akickoff(inputs={"topic": "AI"})
+
+    # 청크에 대한 비동기 반복
+    async for chunk in streaming:
+        print(chunk.content, end="", flush=True)
+
+    # 최종 결과 접근
+    result = streaming.result
+    print(f"\n\n최종 출력: {result.raw}")
+
+asyncio.run(stream_crew())
+```
+
+### `kickoff_async()`를 사용한 스레드 기반 Async
+
+더 간단한 async 통합이나 하위 호환성을 위해:
+
+```python Code
+import asyncio
+
+async def stream_crew():
+    crew = Crew(
+        agents=[researcher],
+        tasks=[task],
+        stream=True
+    )
+
+    # 스레드 기반 async 스트리밍 시작
+    streaming = await crew.kickoff_async(inputs={"topic": "AI"})
+
+    # 청크에 대한 비동기 반복
+    async for chunk in streaming:
+        print(chunk.content, end="", flush=True)
+
+    # 최종 결과 접근
+    result = streaming.result
+    print(f"\n\n최종 출력: {result.raw}")
+
+asyncio.run(stream_crew())
+```
+
+<Note>
+고동시성 워크로드의 경우, 태스크 실행, 메모리 작업, 지식 검색에 네이티브 async를 사용하는 `akickoff()`가 권장됩니다. 자세한 내용은 [Crew 비동기 시작](/ko/learn/kickoff-async) 가이드를 참조하세요.
+</Note>
+
+## kickoff_for_each를 사용한 스트리밍
+
+`kickoff_for_each()`로 여러 입력에 대해 crew를 실행할 때, 동기 또는 비동기 여부에 따라 스트리밍이 다르게 작동합니다:
+
+### 동기 kickoff_for_each
+
+동기 `kickoff_for_each()`를 사용하면, 각 입력에 대해 하나씩 `CrewStreamingOutput` 객체의 리스트가 반환됩니다:
+
+```python Code
+crew = Crew(
+    agents=[researcher],
+    tasks=[task],
+    stream=True
+)
+
+inputs_list = [
+    {"topic": "AI in healthcare"},
+    {"topic": "AI in finance"}
+]
+
+# 스트리밍 출력 리스트 반환
+streaming_outputs = crew.kickoff_for_each(inputs=inputs_list)
+
+# 각 스트리밍 출력에 대해 반복
+for i, streaming in enumerate(streaming_outputs):
+    print(f"\n=== 입력 {i + 1} ===")
+    for chunk in streaming:
+        print(chunk.content, end="", flush=True)
+
+    result = streaming.result
+    print(f"\n\n결과 {i + 1}: {result.raw}")
+```
+
+### 비동기 kickoff_for_each_async
+
+비동기 `kickoff_for_each_async()`를 사용하면, 모든 crew의 청크가 동시에 도착하는 대로 반환하는 단일 `CrewStreamingOutput`이 반환됩니다:
+
+```python Code
+import asyncio
+
+async def stream_multiple_crews():
+    crew = Crew(
+        agents=[researcher],
+        tasks=[task],
+        stream=True
+    )
+
+    inputs_list = [
+        {"topic": "AI in healthcare"},
+        {"topic": "AI in finance"}
+    ]
+
+    # 모든 crew에 대한 단일 스트리밍 출력 반환
+    streaming = await crew.kickoff_for_each_async(inputs=inputs_list)
+
+    # 모든 crew의 청크가 생성되는 대로 도착
+    async for chunk in streaming:
+        print(f"[{chunk.task_name}] {chunk.content}", end="", flush=True)
+
+    # 모든 결과 접근
+    results = streaming.results  # CrewOutput 객체 리스트
+    for i, result in enumerate(results):
+        print(f"\n\n결과 {i + 1}: {result.raw}")
+
+asyncio.run(stream_multiple_crews())
+```
+
+## 스트림 청크 타입
+
+청크는 `chunk_type` 필드로 표시되는 다양한 타입을 가질 수 있습니다:
+
+### TEXT 청크
+
+LLM 응답의 표준 텍스트 콘텐츠:
+
+```python Code
+for chunk in streaming:
+    if chunk.chunk_type == StreamChunkType.TEXT:
+        print(chunk.content, end="", flush=True)
+```
+
+### TOOL_CALL 청크
+
+수행 중인 도구 호출에 대한 정보:
+
+```python Code
+for chunk in streaming:
+    if chunk.chunk_type == StreamChunkType.TOOL_CALL:
+        print(f"\n도구 호출: {chunk.tool_call.tool_name}")
+        print(f"인자: {chunk.tool_call.arguments}")
+```
+
+## 실용적인 예시: 스트리밍을 사용한 UI 구축
+
+다음은 스트리밍을 사용한 대화형 애플리케이션을 구축하는 방법을 보여주는 완전한 예시입니다:
+
+```python Code

+        role="Research Analyst",
+        goal="Provide detailed analysis on any topic",
+        backstory="You are an expert researcher with broad knowledge.",
+    )
+
+    task = Task(
+        description="Research and analyze: {topic}",
+        expected_output="A comprehensive analysis with key insights",
+        agent=researcher,
+    )
+
+    crew = Crew(
+        agents=[researcher],

+    print(f"연구 중: {topic}")
+    print(f"{'='*60}\n")
+
+    # 스트리밍 실행 시작
+    streaming = await crew.kickoff_async(inputs={"topic": topic})
+
+    current_task = ""
+    async for chunk in streaming:
+        # 태스크 전환 표시
+        if chunk.task_name != current_task:
+            current_task = chunk.task_name
+            print(f"\n[{chunk.agent_role}] 작업 중: {chunk.task_name}")
+            print("-" * 60)
+
+        # 텍스트 청크 표시
+        if chunk.chunk_type == StreamChunkType.TEXT:
+            print(chunk.content, end="", flush=True)
+
+        # 도구 호출 표시
+        elif chunk.chunk_type == StreamChunkType.TOOL_CALL and chunk.tool_call:
+            print(f"\n🔧 도구 사용: {chunk.tool_call.tool_name}")
+
+    # 최종 결과 표시
+    result = streaming.result
+    print(f"\n\n{'='*60}")
+    print("분석 완료!")
+    print(f"{'='*60}")
+    print(f"\n토큰 사용량: {result.token_usage}")
+
+asyncio.run(interactive_research())
+```
+
+## 사용 사례
+
+스트리밍은 다음과 같은 경우에 특히 유용합니다:
+
+- **대화형 애플리케이션**: 에이전트가 작업하는 동안 사용자에게 실시간 피드백 제공
+- **장시간 실행 태스크**: 연구, 분석 또는 콘텐츠 생성의 진행 상황 표시
+- **디버깅 및 모니터링**: 에이전트 동작과 의사 결정을 실시간으로 관찰
+- **사용자 경험**: 점진적인 결과를 표시하여 체감 지연 시간 감소
+- **라이브 대시보드**: crew 실행 상태를 표시하는 모니터링 인터페이스 구축
+
+## 중요 사항
+
+- 스트리밍은 crew의 모든 에이전트에 대해 자동으로 LLM 스트리밍을 활성화합니다
+- `.result` 속성에 접근하기 전에 모든 청크를 반복해야 합니다
+- 스트리밍을 사용하는 `kickoff_for_each_async()`의 경우, 모든 출력을 가져오려면 `.results`(복수형)를 사용하세요
+- 스트리밍은 최소한의 오버헤드를 추가하며 실제로 체감 성능을 향상시킬 수 있습니다
+- 각 청크는 풍부한 UI를 위한 전체 컨텍스트(태스크, 에이전트, 청크 타입)를 포함합니다
+
+## 오류 처리
+
+스트리밍 실행 중 오류 처리:
+
+```python Code
+streaming = crew.kickoff(inputs={"topic": "AI"})
+
+try:
+    for chunk in streaming:

+title: Streaming na Execução da Crew
+description: Transmita saída em tempo real da execução da sua crew no CrewAI
+icon: wave-pulse
+mode: "wide"
+---
+
+## Introdução
+
+O CrewAI fornece a capacidade de transmitir saída em tempo real durante a execução da crew, permitindo que você exiba resultados conforme são gerados, em vez de esperar que todo o processo seja concluído. Este recurso é particularmente útil para construir aplicações interativas, fornecer feedback ao usuário e monitorar processos de longa duração.
+
+## Como o Streaming Funciona
+
+Quando o streaming está ativado, o CrewAI captura respostas do LLM e chamadas de ferramentas conforme acontecem, empacotando-as em chunks estruturados que incluem contexto sobre qual task e agent está executando. Você pode iterar sobre esses chunks em tempo real e acessar o resultado final quando a execução for concluída.
+
+## Ativando o Streaming
+
+Para ativar o streaming, defina o parâmetro `stream` como `True` ao criar sua crew:
+
+```python Code
+from crewai import Agent, Crew, Task
+
+# Crie seus agentes e tasks
+researcher = Agent(
+    role="Research Analyst",
+    goal="Gather comprehensive information on topics",
+    backstory="You are an experienced researcher with excellent analytical skills.",
+)
+
+task = Task(
+    description="Research the latest developments in AI",
+    expected_output="A detailed report on recent AI advancements",
+    agent=researcher,
+)
+
+# Ativar streaming
+crew = Crew(
+    agents=[researcher],
+    tasks=[task],
+    stream=True  # Ativar saída em streaming
+)
+```
+
+## Streaming Síncrono
+
+Quando você chama `kickoff()` em uma crew com streaming ativado, ele retorna um objeto `CrewStreamingOutput` que você pode iterar para receber chunks conforme chegam:
+
+```python Code
+# Iniciar execução com streaming
+streaming = crew.kickoff(inputs={"topic": "artificial intelligence"})
+
+# Iterar sobre chunks conforme chegam
+for chunk in streaming:
+    print(chunk.content, end="", flush=True)
+
+# Acessar o resultado final após o streaming completar
+result = streaming.result
+print(f"\n\nSaída final: {result.raw}")
+```
+
+### Informações do Chunk de Stream
+
+Cada chunk fornece contexto rico sobre a execução:
+
+```python Code
+streaming = crew.kickoff(inputs={"topic": "AI"})
+
+for chunk in streaming:
+    print(f"Task: {chunk.task_name} (índice {chunk.task_index})")
+    print(f"Agent: {chunk.agent_role}")
+    print(f"Content: {chunk.content}")
+    print(f"Type: {chunk.chunk_type}")  # TEXT ou TOOL_CALL
+    if chunk.tool_call:
+        print(f"Tool: {chunk.tool_call.tool_name}")
+        print(f"Arguments: {chunk.tool_call.arguments}")
+```
+
+### Acessando Resultados do Streaming
+
+O objeto `CrewStreamingOutput` fornece várias propriedades úteis:
+
+```python Code
+streaming = crew.kickoff(inputs={"topic": "AI"})
+
+# Iterar e coletar chunks
+for chunk in streaming:
+    print(chunk.content, end="", flush=True)
+
+# Após a iteração completar
+print(f"\nCompletado: {streaming.is_completed}")
+print(f"Texto completo: {streaming.get_full_text()}")
+print(f"Todos os chunks: {len(streaming.chunks)}")
+print(f"Resultado final: {streaming.result.raw}")
+```
+
+## Streaming Assíncrono
+
+Para aplicações assíncronas, você pode usar `akickoff()` (async nativo) ou `kickoff_async()` (baseado em threads) com iteração assíncrona:
+
+### Async Nativo com `akickoff()`
+
+O método `akickoff()` fornece execução async nativa verdadeira em toda a cadeia:
+
+```python Code
+import asyncio
+
+async def stream_crew():
+    crew = Crew(
+        agents=[researcher],
+        tasks=[task],
+        stream=True
+    )
+
+    # Iniciar streaming async nativo
+    streaming = await crew.akickoff(inputs={"topic": "AI"})

+
+    # Acessar resultado final
+    result = streaming.result
+    print(f"\n\nSaída final: {result.raw}")
+
+asyncio.run(stream_crew())
+```
+
+### Async Baseado em Threads com `kickoff_async()`
+
+Para integração async mais simples ou compatibilidade retroativa:
+
+```python Code
+import asyncio
+
+async def stream_crew():
+    crew = Crew(
+        agents=[researcher],
+        tasks=[task],
+        stream=True
+    )
+
+    # Iniciar streaming async baseado em threads
+    streaming = await crew.kickoff_async(inputs={"topic": "AI"})
+
+    # Iteração assíncrona sobre chunks
+    async for chunk in streaming:
+        print(chunk.content, end="", flush=True)
+
+    # Acessar resultado final
+    result = streaming.result
+    print(f"\n\nSaída final: {result.raw}")
+
+asyncio.run(stream_crew())
+```
+
+<Note>
+Para cargas de trabalho de alta concorrência, `akickoff()` é recomendado pois usa async nativo para execução de tasks, operações de memória e recuperação de conhecimento. Consulte o guia [Iniciar Crew de Forma Assíncrona](/pt-BR/learn/kickoff-async) para mais detalhes.

+
+## Streaming com kickoff_for_each
+
+Ao executar uma crew para múltiplas entradas com `kickoff_for_each()`, o streaming funciona de forma diferente dependendo se você usa síncrono ou assíncrono:
+
+### kickoff_for_each Síncrono
+
+Com `kickoff_for_each()` síncrono, você obtém uma lista de objetos `CrewStreamingOutput`, um para cada entrada:
+
+```python Code
+crew = Crew(
+    agents=[researcher],
+    tasks=[task],
+    stream=True
+)
+
+inputs_list = [
+    {"topic": "AI in healthcare"},
+    {"topic": "AI in finance"}
+]
+
+# Retorna lista de saídas de streaming
+streaming_outputs = crew.kickoff_for_each(inputs=inputs_list)
+
+# Iterar sobre cada saída de streaming
+for i, streaming in enumerate(streaming_outputs):
+    print(f"\n=== Entrada {i + 1} ===")
+    for chunk in streaming:
+        print(chunk.content, end="", flush=True)
+
+    result = streaming.result
+    print(f"\n\nResultado {i + 1}: {result.raw}")
+```
+
+### kickoff_for_each_async Assíncrono
+
+Com `kickoff_for_each_async()` assíncrono, você obtém um único `CrewStreamingOutput` que produz chunks de todas as crews conforme chegam concorrentemente:
+
+```python Code
+import asyncio
+
+async def stream_multiple_crews():
+    crew = Crew(
+        agents=[researcher],
+        tasks=[task],
+        stream=True
+    )
+
+    inputs_list = [
+        {"topic": "AI in healthcare"},
+        {"topic": "AI in finance"}
+    ]
+
+    # Retorna saída de streaming única para todas as crews
+    streaming = await crew.kickoff_for_each_async(inputs=inputs_list)
+
+    # Chunks de todas as crews chegam conforme são gerados
+    async for chunk in streaming:
+        print(f"[{chunk.task_name}] {chunk.content}", end="", flush=True)
+
+    # Acessar todos os resultados
+    results = streaming.results  # Lista de objetos CrewOutput
+    for i, result in enumerate(results):
+        print(f"\n\nResultado {i + 1}: {result.raw}")
+
+asyncio.run(stream_multiple_crews())
+```
+
+## Tipos de Chunk de Stream
+
+Chunks podem ser de diferentes tipos, indicados pelo campo `chunk_type`:
+
+### Chunks TEXT
+
+Conteúdo de texto padrão de respostas do LLM:
+
+```python Code
+for chunk in streaming:
+    if chunk.chunk_type == StreamChunkType.TEXT:
+        print(chunk.content, end="", flush=True)
+```
+
+### Chunks TOOL_CALL
+
+Informações sobre chamadas de ferramentas sendo feitas:
+
+```python Code
+for chunk in streaming:
+    if chunk.chunk_type == StreamChunkType.TOOL_CALL:
+        print(f"\nChamando ferramenta: {chunk.tool_call.tool_name}")
+        print(f"Argumentos: {chunk.tool_call.arguments}")
+```
+
+## Exemplo Prático: Construindo uma UI com Streaming
+
+Aqui está um exemplo completo mostrando como construir uma aplicação interativa com streaming:
+
+```python Code
+import asyncio
+from crewai import Agent, Crew, Task
+from crewai.types.streaming import StreamChunkType
+
+async def interactive_research():
+    # Criar crew com streaming ativado
+    researcher = Agent(
+        role="Research Analyst",
+        goal="Provide detailed analysis on any topic",
+        backstory="You are an expert researcher with broad knowledge.",
+    )
+
+    task = Task(
+        description="Research and analyze: {topic}",
+        expected_output="A comprehensive analysis with key insights",
+        agent=researcher,
+    )
+
+    crew = Crew(
+        agents=[researcher],
+        tasks=[task],
+        stream=True,
+        verbose=False
+    )
+
+    # Obter entrada do usuário
+    topic = input("Digite um tópico para pesquisar: ")
+
+    print(f"\n{'='*60}")
+    print(f"Pesquisando: {topic}")
+    print(f"{'='*60}\n")
+
+    # Iniciar execução com streaming
+    streaming = await crew.kickoff_async(inputs={"topic": topic})
+
+    current_task = ""
+    async for chunk in streaming:
+        # Mostrar transições de task
+        if chunk.task_name != current_task:
+            current_task = chunk.task_name
+            print(f"\n[{chunk.agent_role}] Trabalhando em: {chunk.task_name}")
+            print("-" * 60)
+
+        # Exibir chunks de texto
+        if chunk.chunk_type == StreamChunkType.TEXT:
+            print(chunk.content, end="", flush=True)
+
+        # Exibir chamadas de ferramentas
+        elif chunk.chunk_type == StreamChunkType.TOOL_CALL and chunk.tool_call:
+            print(f"\n🔧 Usando ferramenta: {chunk.tool_call.tool_name}")
+
+    # Mostrar resultado final
+    result = streaming.result
+    print(f"\n\n{'='*60}")
+    print("Análise Completa!")
+    print(f"{'='*60}")
+    print(f"\nUso de Tokens: {result.token_usage}")
+
+asyncio.run(interactive_research())
+```
+
+## Casos de Uso
+
+O streaming é particularmente valioso para:
+
+- **Aplicações Interativas**: Fornecer feedback em tempo real aos usuários enquanto os agentes trabalham
+- **Tasks de Longa Duração**: Mostrar progresso para pesquisa, análise ou geração de conteúdo
+- **Depuração e Monitoramento**: Observar comportamento e tomada de decisão dos agentes em tempo real
+- **Experiência do Usuário**: Reduzir latência percebida mostrando resultados incrementais
+- **Dashboards ao Vivo**: Construir interfaces de monitoramento que exibem status de execução da crew
+
+## Notas Importantes
+
+- O streaming ativa automaticamente o streaming do LLM para todos os agentes na crew
+- Você deve iterar através de todos os chunks antes de acessar a propriedade `.result`
+- Para `kickoff_for_each_async()` com streaming, use `.results` (plural) para obter todas as saídas
+- O streaming adiciona overhead mínimo e pode realmente melhorar a performance percebida
+- Cada chunk inclui contexto completo (task, agente, tipo de chunk) para UIs ricas
+
+## Tratamento de Erros
+
+Trate erros durante a execução com streaming:
+
+```python Code
+streaming = crew.kickoff(inputs={"topic": "AI"})
+
+try:
+    for chunk in streaming:
+        print(chunk.content, end="", flush=True)
+
+    result = streaming.result
+    print(f"\nSucesso: {result.raw}")
+
+except Exception as e:
+    print(f"\nErro durante o streaming: {e}")
+    if streaming.is_completed:
+        print("O streaming foi completado mas ocorreu um erro")
+```
+
+Ao aproveitar o streaming, você pode construir aplicações mais responsivas e interativas com o CrewAI, fornecendo aos usuários visibilidade em tempo real da execução dos agentes e resultados.
