aiohttp 3.14.0 (pulled in to fix GHSA-jg22-mg44-37j8 and GHSA-hg6j-4rv6-33pg):
* removed ``aiohttp.streams.AsyncStreamReaderMixin`` (folded into ``StreamReader``),
which vcrpy's ``MockStream`` still subclasses -- vcr's patch machinery then raises
``AttributeError`` at collection time; and
* added a required ``stream_writer`` keyword-only arg to ``ClientResponse.__init__``,
which vcrpy's ``MockClientResponse`` does not pass -- raising ``TypeError`` at
cassette playback.
Restore the mixin, then rebuild ``MockClientResponse``'s ``super().__init__`` call from
the live ``ClientResponse`` signature (defaulting every required keyword-only arg to
``None``, mirroring vcrpy's original call) so it also survives future aiohttp additions.

من خلال ضمان إعادة مخرجات الدالة الأخيرة وتوفير الوصول إلى الحالة، تجعل تدفقات CrewAI من السهل دمج نتائج سير عمل الذكاء الاصطناعي في التطبيقات أو الأنظمة الأكبر،
مع الحفاظ على الوصول إلى الحالة طوال تنفيذ التدفق.
## مقاييس استخدام التدفق
بعد اكتمال تنفيذ التدفق، يمكنك الوصول إلى الخاصية `usage_metrics` لعرض إجمالي استخدام التوكنات عبر **كل استدعاء لنموذج اللغة** يتم خلال التشغيل — بما في ذلك الاستدعاءات من كل فريق (Crew) ينظمه التدفق، والاستدعاءات داخل أدوات الـ Agents، والاستدعاءات المباشرة لـ `LLM.call(...)` من دوال التدفق. هذا هو المكافئ على جانب الـ SDK للإجماليات المعروضة في واجهة CrewAI Enterprise.
```python Code
from crewai import LLM
from crewai.flow.flow import Flow, listen, start
class UsageMetricsFlow(Flow):
@start()
def run_first_crew(self):
self.state.first_result = FirstCrew().crew().kickoff()
@listen(run_first_crew)
def call_llm_directly(self):
# استدعاء مباشر لنموذج اللغة — يُحسب أيضًا ضمن flow.usage_metrics
llm = LLM(model="openai/gpt-4o-mini")
self.state.summary = llm.call("لخّص النقاط الرئيسية.")
@listen(call_llm_directly)
def run_second_crew(self):
self.state.second_result = SecondCrew().crew().kickoff()
flow = UsageMetricsFlow()
flow.kickoff()
print(flow.usage_metrics)
# UsageMetrics(total_tokens=8579, prompt_tokens=6210, completion_tokens=2369,
# cached_prompt_tokens=0, reasoning_tokens=0,
# cache_creation_tokens=0, successful_requests=5)
```
<Note>
`flow.usage_metrics` **ليست** نفس `flow.kickoff().token_usage`. هذه الأخيرة
ترجع فقط `CrewOutput.token_usage` لـ **آخر** دالة `@listen` أعادت
`CrewOutput`، مما يعني أنها تعكس فقط الفريق الأخير وتتجاهل الفرق السابقة
وكذلك أي استدعاءات مباشرة لـ `LLM.call(...)`. استخدم `flow.usage_metrics`
كلما احتجت إلى الإجمالي **الكامل** للتوكنات لتنفيذ التدفق.
</Note>
كل حقل في [`UsageMetrics`](https://github.com/crewAIInc/crewAI/blob/main/lib/crewai/src/crewai/types/usage_metrics.py) المُعاد هو مجموع جميع استدعاءات نموذج اللغة التي حدثت خلال استدعاء واحد لـ `flow.kickoff()`. تتم إعادة تعيين العدادات عند الاستدعاء التالي لـ `kickoff()` (وفي كل تكرار من `kickoff_for_each`)، لذلك لن تتكرر العدّات عبر التشغيلات المتتالية. يمكن قراءة هذه الخاصية بأمان في أي وقت بعد اكتمال `kickoff()`؛ قراءتها أثناء التنفيذ تُرجع المجموع الجزئي المتراكم حتى تلك اللحظة.
## إدارة حالة التدفق
إدارة الحالة بفعالية أمر بالغ الأهمية لبناء سير عمل ذكاء اصطناعي موثوق وقابل للصيانة. توفر تدفقات CrewAI آليات قوية لإدارة الحالة غير المهيكلة والمهيكلة،

تعامل التطبيقات المحادثية مع كل سطر من المستخدم كـ **تشغيل flow جديد** بنفس **معرّف الجلسة**. توفر CrewAI مساعدات لسجل الرسائل وتصنيف النية الاختياري وتأجيل التتبع وجسور الواجهة — دون API منفصل `chat()` على `Flow`.
| المفهوم | التنفيذ |
|---------|---------|
| معرّف الجلسة | `handle_turn(..., session_id=...)` → `kickoff(inputs={"id": ...})` → `state.id` |
| سطر المستخدم | `handle_turn(message)` يضيف الرسالة إلى `state.messages` قبل تشغيل الرسم |

## واجهات الجولات
## نقطة دخول واحدة: `kickoff`
استخدم **`flow.handle_turn(message, session_id=...)`** لكل رسالة مستخدم من REST أو WebSocket أو الاختبارات أو الواجهات المخصصة. استخدم **`flow.chat()`** عندما تريد حلقة دردشة محلية في الطرفية لـ `Flow` محادثي.
لا يقبل `Flow.kickoff()` الوسيطين `user_message=` أو `session_id=`. في التدفقات المحادثية، يخزن `handle_turn()` الرسالة المعلقة ويستدعي داخلياً `kickoff(inputs={"id": session_id})`.
استخدم **`flow.kickoff(user_message=..., session_id=...)`** لكل رسالة مستخدم (REST أو WebSocket أو CLI). لا تنشئ غلاف `chat()` مخصصاً على `Flow`.
| API | الاستخدام |
|-----|-----------|
| `handle_turn(message, session_id=...)` | غلاف مريح لجولة واحدة في `Flow` محادثي |
| `chat()` | REPL محلي في الطرفية لـ `Flow` محادثي |
| `kickoff(inputs={...})` | تشغيل متقدم للـ flow بدون معالجة جولة محادثية |
| `kickoff(user_message=..., session_id=...)` | كل رسالة مستخدم |
| `kickoff_async(...)` | نفس المعاملات؛ دخول async أصلي |
| `ask()` | مطالبة حاجزة **داخل** خطوة واحدة |
| `@human_feedback` | الموافقة/الرفض على **مخرجات خطوة** — وليس السطر التالي |
| `ChatSession.handle_turn(...)` | طبقة نقل فوق `handle_turn` |

@@ -226,49 +226,6 @@ After the Flow has run, you can access the final state to see the updates made b
By ensuring that the final method's output is returned and providing access to the state, CrewAI Flows make it easy to integrate the results of your AI workflows into larger applications or systems,
while also maintaining and accessing the state throughout the Flow's execution.
## Flow Usage Metrics
After a Flow execution completes, you can access the `usage_metrics` property to view aggregated token usage across **every LLM call** made during the run — including calls from every Crew the Flow orchestrated, calls inside Agent tools, and bare `LLM.call(...)` invocations from Flow methods. This is the SDK-side equivalent of the totals shown in the CrewAI Enterprise UI.
```python Code
from crewai import LLM
from crewai.flow.flow import Flow, listen, start
class UsageMetricsFlow(Flow):
@start()
def run_first_crew(self):
self.state.first_result = FirstCrew().crew().kickoff()
@listen(run_first_crew)
def call_llm_directly(self):
# Bare LLM call — still counted by flow.usage_metrics
llm = LLM(model="openai/gpt-4o-mini")
self.state.summary = llm.call("Summarize the key takeaways.")
@listen(call_llm_directly)
def run_second_crew(self):
self.state.second_result = SecondCrew().crew().kickoff()
flow = UsageMetricsFlow()
flow.kickoff()
print(flow.usage_metrics)
# UsageMetrics(total_tokens=8579, prompt_tokens=6210, completion_tokens=2369,
# cached_prompt_tokens=0, reasoning_tokens=0,
# cache_creation_tokens=0, successful_requests=5)
```
<Note>
`flow.usage_metrics` is **not** the same as `flow.kickoff().token_usage`. The
latter returns the `CrewOutput.token_usage` of the **last** `@listen` method
that returned a `CrewOutput`, which means it only reflects the final Crew and
ignores prior Crews and bare `LLM.call(...)` invocations entirely. Use
`flow.usage_metrics` whenever you need the **full** token rollup for the Flow
execution.
</Note>
Each entry in the returned [`UsageMetrics`](https://github.com/crewAIInc/crewAI/blob/main/lib/crewai/src/crewai/types/usage_metrics.py) is the sum across all LLM calls made within a single `flow.kickoff()` invocation. Counters reset on the next `kickoff()` call (or on each iteration of `kickoff_for_each`), so successive runs don't double-count. The property is safe to read at any point after `kickoff()` completes; reading it during execution returns the partial total accumulated so far.
## Flow State Management
Managing state effectively is crucial for building reliable and maintainable AI workflows. CrewAI Flows provides robust mechanisms for both unstructured and structured state management,

## Overview
Conversational apps treat each user line as a **new flow run** with the **same session id**. CrewAI adds helpers for message history, optional intent routing, deferred tracing, UI bridges, and a local `flow.chat()` REPL for conversational flows.
Conversational apps treat each user line as a **new flow run** with the **same session id**. CrewAI adds helpers for message history, optional intent classification, deferred tracing, and UI bridges — without a separate `chat()` API on `Flow`.
| Concept | Implementation |
|---------|----------------|
| Session id | `handle_turn(..., session_id=...)` → `kickoff(inputs={"id": ...})` → `state.id` |
| User line | `handle_turn(message)` appends to `state.messages` before the graph runs |
| Turn complete | `FlowFinished` for **this run** only; chat continues on the next `handle_turn` |
| Full-session trace | `ConversationConfig(defer_trace_finalization=True)` + `finalize_session_traces()` |
| Session id | `kickoff(session_id=...)` → `inputs["id"]` → `state.id` |
| User line | `kickoff(user_message=...)` appends to `state.messages` before the graph runs |
| Turn complete | `FlowFinished` for **this run** only; chat continues on the next `kickoff` |
| Full-session trace | `ConversationalConfig(defer_trace_finalization=True)` + `finalize_session_traces()` |
## Turn APIs
## One entry point: `kickoff`
Use **`flow.handle_turn(message, session_id=...)`** for every user message from REST, WebSocket, tests, and custom UIs. Use **`flow.chat()`** when you want a local terminal chat loop for a conversational `Flow`.
`Flow.kickoff()` does **not** accept `user_message=` or `session_id=` keyword arguments. For conversational flows, `handle_turn()` stores the pending message and calls `kickoff(inputs={"id": session_id})` internally after resetting per-turn execution state.
Use **`flow.kickoff(user_message=..., session_id=...)`** for every user message (REST, WebSocket, CLI). Do not add a custom `chat()` wrapper on `Flow`.
| API | Use for |
|-----|---------|
| `handle_turn(message, session_id=...)` | Ergonomic one-turn wrapper for conversational `Flow` |
| `chat()` | Local terminal REPL for conversational `Flow` |
| `kickoff(inputs={...})` | Advanced flow execution without conversational turn handling |
| `kickoff(user_message=..., session_id=...)` | Each user message |
| `kickoff_async(...)` | Same parameters; native async entry |
| `ask()` | Blocking prompt **inside** one step (wizard, clarification) |
| `@human_feedback` | Approve/reject **a step output** — not the next chat line |
| `ChatSession.handle_turn(...)` | Transport layer over `handle_turn` (SSE / WebSocket) |
| `ChatSession.handle_turn(...)` | Transport layer over `kickoff` (SSE / WebSocket) |

```
## Turn lifecycle
Each `handle_turn` runs this pipeline:
Each `kickoff` with `user_message` runs this pipeline:
1. **Turn setup** — stores the pending user message, resolves the session id, resets per-turn execution tracking, and calls `kickoff(inputs={"id": session_id})`.
1. **`_configure_conversational_kickoff`** — merges `session_id` / `user_message` into `inputs`, applies `ConversationalConfig`, enables deferred tracing when configured.
2. **State restore** — if `inputs["id"]` exists and `@persist` is configured, loads the latest snapshot.
3. **`FlowStarted`** — emitted on the first deferred session turn only.
4. **Pending turn hydration** — appends the user message to `state.messages`, sets `current_user_message` / `last_user_message`, and optionally classifies when `intents` / `default_intents` + `intent_llm` are set.
5. **Graph execution** — `conversation_start` → `route_conversation` → the selected `@listen` handler.
4. **`prepare_conversational_turn`** — appends the user message to `state.messages`, sets `last_user_message`, clears `last_intent`, optionally classifies when `intents` / `default_intents` + `intent_llm` are set.
5. **Graph execution** — `@start` → `@router` → `@listen` handlers.
6. **End of run** — per-turn `flow_finished` and trace finalization are **skipped** when deferral is enabled; nested `Agent.kickoff()` / crews do not close the parent batch either.
Handlers should call **`append_assistant_message(reply)`** so the next turns `conversation_messages` includes assistant text. The user line is already stored by `handle_turn` — do not append it again in handlers.

4. The router stores its decision in `state.last_intent` (visible to the next turn's router context).
5. If your handler returned a string and didn't already call `append_assistant_message`, `handle_turn` appends it for you.
Call `handle_turn()` for chat messages. Calling `kickoff(inputs={"id": ...})` directly runs the flow graph without applying the conversational turn wrapper.
### `chat()` for local REPLs
`flow.chat()` is the batteries-included terminal wrapper around `handle_turn()`:
```python
flow = SupportFlow()
flow.chat()
```
It handles the common local loop:
1. Prompts for a user message.
2. Stops on `exit` / `quit`, `EOFError`, or `KeyboardInterrupt`.
3. Calls `handle_turn(message, session_id=...)`.
4. Prints the assistant result.
5. Finalizes deferred session traces in a `finally` block.
Customize the terminal behavior with injectable I/O:
```python
flow.chat(
session_id="demo-session",
prompt="You: ",
assistant_prefix="Assistant: ",
exit_commands=("exit", "quit", "bye"),
)
```
For web apps, background workers, tests, and custom transports, keep using `handle_turn()` directly.
You can also call `flow.kickoff(user_message=..., session_id=...)` directly the same reset/run logic fires. `handle_turn` is the ergonomic wrapper.
### Custom router behavior
To run side effects (event bus setup, telemetry) on every routing decision, override `route_turn`:

최종 메소드의 출력이 반환되고 상태에 접근할 수 있도록 함으로써, CrewAI Flow는 AI 워크플로우의 결과를 더 큰 애플리케이션이나 시스템에 쉽게 통합할 수 있게 하며,
Flow 실행 과정 전반에 걸쳐 상태를 유지하고 접근하면서도 이를 용이하게 만듭니다.
## 플로우 사용 메트릭
Flow 실행이 완료된 후, `usage_metrics` 속성에 접근하여 실행 동안 발생한 **모든 LLM 호출**의 토큰 사용량 집계를 확인할 수 있습니다. 여기에는 Flow가 오케스트레이션한 모든 Crew의 호출, Agent의 도구 내부에서 발생한 호출, 그리고 Flow 메서드에서 직접 호출한 `LLM.call(...)`이 모두 포함됩니다. 이는 CrewAI Enterprise UI에 표시되는 총량과 동등한 SDK 측 값입니다.
```python Code
from crewai import LLM
from crewai.flow.flow import Flow, listen, start
class UsageMetricsFlow(Flow):
@start()
def run_first_crew(self):
self.state.first_result = FirstCrew().crew().kickoff()
@listen(run_first_crew)
def call_llm_directly(self):
# 직접 LLM 호출 — flow.usage_metrics에서도 집계됩니다
llm = LLM(model="openai/gpt-4o-mini")
self.state.summary = llm.call("핵심 내용을 요약해 주세요.")
@listen(call_llm_directly)
def run_second_crew(self):
self.state.second_result = SecondCrew().crew().kickoff()
flow = UsageMetricsFlow()
flow.kickoff()
print(flow.usage_metrics)
# UsageMetrics(total_tokens=8579, prompt_tokens=6210, completion_tokens=2369,
# cached_prompt_tokens=0, reasoning_tokens=0,
# cache_creation_tokens=0, successful_requests=5)
```
<Note>
`flow.usage_metrics`는 `flow.kickoff().token_usage`와 **동일하지 않습니다**.
후자는 `CrewOutput`을 반환한 **마지막** `@listen` 메서드의
`CrewOutput.token_usage`만 반환하므로, 이전에 실행된 Crew들과 Flow 메서드에서
직접 호출한 `LLM.call(...)`은 전혀 포함되지 않습니다. Flow 실행에 대한
**전체** 토큰 집계가 필요할 때는 항상 `flow.usage_metrics`를 사용하십시오.
</Note>
반환되는 [`UsageMetrics`](https://github.com/crewAIInc/crewAI/blob/main/lib/crewai/src/crewai/types/usage_metrics.py)의 각 항목은 단일 `flow.kickoff()` 실행 동안 발생한 모든 LLM 호출의 합계입니다. 다음 `kickoff()` 호출(및 `kickoff_for_each`의 각 반복)에서 카운터가 초기화되므로 연속 실행이 이중으로 집계되지 않습니다. 이 속성은 `kickoff()` 완료 후 언제든지 안전하게 읽을 수 있으며, 실행 중에 읽으면 그 시점까지 누적된 부분 합계를 반환합니다.
## 플로우 상태 관리
상태를 효과적으로 관리하는 것은 신뢰할 수 있고 유지 보수가 용이한 AI 워크플로를 구축하는 데 매우 중요합니다. CrewAI 플로우는 비정형 및 정형 상태 관리를 위한 강력한 메커니즘을 제공하여, 개발자가 자신의 애플리케이션에 가장 적합한 접근 방식을 선택할 수 있도록 합니다.

대화형 앱은 각 사용자 입력을 **동일한 세션 id**로 **새 flow 실행**으로 처리합니다. CrewAI는 메시지 기록, 선택적 의도 분류, 지연 트레이싱, UI 브리지를 제공하며, `Flow`에 별도 `chat()` API는 없습니다.
| 개념 | 구현 |
|------|------|
| 세션 id | `handle_turn(..., session_id=...)` → `kickoff(inputs={"id": ...})` → `state.id` |
| 사용자 입력 | `handle_turn(message)`가 그래프 실행 전 `state.messages`에 추가 |
| 턴 완료 | `FlowFinished`는 **이번 실행**만 의미; 다음 `handle_turn`로 대화 계속 |
| 세션 전체 트레이스 | `ConversationConfig(defer_trace_finalization=True)` + `finalize_session_traces()` |
| 세션 id | `kickoff(session_id=...)` → `inputs["id"]` → `state.id` |
| 사용자 입력 | `kickoff(user_message=...)`가 그래프 실행 전 `state.messages`에 추가 |
| 턴 완료 | `FlowFinished`는 **이번 실행**만 의미; 다음 `kickoff`로 대화 계속 |
| 세션 전체 트레이스 | `ConversationalConfig(defer_trace_finalization=True)` + `finalize_session_traces()` |
## 턴 API
## 단일 진입점: `kickoff`
REST, WebSocket, 테스트, 커스텀 UI에서 오는 모든 사용자 메시지에 **`flow.handle_turn(message, session_id=...)`**를 사용하세요. 대화형 `Flow`를 로컬 터미널 채팅 루프로 실행하고 싶을 때는 **`flow.chat()`**을 사용하세요.
`Flow.kickoff()`는 `user_message=` 또는 `session_id=` 키워드 인자를 받지 않습니다. 대화형 flow에서는 `handle_turn()`이 보류 중인 메시지를 저장하고 내부적으로 `kickoff(inputs={"id": session_id})`를 호출합니다.
모든 사용자 메시지에 **`flow.kickoff(user_message=..., session_id=...)`**를 사용하세요 (REST, WebSocket, CLI). `Flow`에 커스텀 `chat()` 래퍼를 만들지 마세요.
| API | 용도 |
|-----|------|
| `handle_turn(message, session_id=...)` | 대화형 `Flow`용 한 턴 편의 래퍼 |
| `chat()` | 대화형 `Flow`용 로컬 터미널 REPL |
| `kickoff(inputs={...})` | 대화형 턴 처리 없이 flow를 직접 실행 |
| `kickoff(user_message=..., session_id=...)` | 각 사용자 메시지 |
| `kickoff_async(...)` | 동일 파라미터; 네이티브 async 진입 |
| `ask()` | 한 스텝 **내부** 블로킹 프롬프트 (마법사, 확인) |
| `@human_feedback` | **스텝 출력** 승인/거부 — 다음 채팅 줄이 아님 |
| `ChatSession.handle_turn(...)` | `handle_turn` 위의 전송 계층 (SSE / WebSocket) |
| `ChatSession.handle_turn(...)` | `kickoff` 위의 전송 계층 (SSE / WebSocket) |

Ao garantir que a saída do método final seja retornada e oferecer acesso ao estado, o CrewAI Flows facilita a integração dos resultados dos seus workflows de IA em aplicações maiores,
além de permitir o gerenciamento e o acesso ao estado durante toda a execução do Flow.
## Métricas de Uso do Flow
Após a execução de um Flow, você pode acessar a propriedade `usage_metrics` para visualizar o consumo agregado de tokens em **todas as chamadas de LLM** realizadas durante a execução — incluindo chamadas das Crews orquestradas pelo Flow, chamadas dentro de tools de Agents, e invocações diretas de `LLM.call(...)` feitas a partir de métodos do Flow. Esse é o equivalente, do lado do SDK, ao total exibido na interface do CrewAI Enterprise.
```python Code
from crewai import LLM
from crewai.flow.flow import Flow, listen, start
class UsageMetricsFlow(Flow):
@start()
def run_first_crew(self):
self.state.first_result = FirstCrew().crew().kickoff()
@listen(run_first_crew)
def call_llm_directly(self):
# Chamada direta de LLM — também contabilizada por flow.usage_metrics
llm = LLM(model="openai/gpt-4o-mini")
self.state.summary = llm.call("Resuma os principais pontos.")
@listen(call_llm_directly)
def run_second_crew(self):
self.state.second_result = SecondCrew().crew().kickoff()
flow = UsageMetricsFlow()
flow.kickoff()
print(flow.usage_metrics)
# UsageMetrics(total_tokens=8579, prompt_tokens=6210, completion_tokens=2369,
# cached_prompt_tokens=0, reasoning_tokens=0,
# cache_creation_tokens=0, successful_requests=5)
```
<Note>
`flow.usage_metrics` **não** é o mesmo que `flow.kickoff().token_usage`. Este
último retorna apenas o `CrewOutput.token_usage` do **último** método
`@listen` que retornou um `CrewOutput`, ou seja, reflete somente a Crew
final e ignora completamente as Crews anteriores e quaisquer chamadas
diretas de `LLM.call(...)`. Use `flow.usage_metrics` sempre que precisar do
rollup **completo** de tokens da execução do Flow.
</Note>
Cada campo do [`UsageMetrics`](https://github.com/crewAIInc/crewAI/blob/main/lib/crewai/src/crewai/types/usage_metrics.py) retornado representa a soma de todas as chamadas de LLM feitas em uma única invocação de `flow.kickoff()`. Os contadores são resetados a cada novo `kickoff()` (e em cada iteração de `kickoff_for_each`), de modo que execuções sucessivas não duplicam o total. A propriedade é segura para ser lida em qualquer momento após o `kickoff()`; lê-la durante a execução retorna o total parcial acumulado até aquele instante.
## Gerenciamento de Estado em Flows
Gerenciar o estado de forma eficaz é fundamental para construir fluxos de trabalho de IA confiáveis e de fácil manutenção. O CrewAI Flows oferece mecanismos robustos para o gerenciamento de estado tanto não estruturado quanto estruturado,

## Visão geral
Apps conversacionais tratam cada linha do usuário como uma **nova execução do flow** com o **mesmo id de sessão**. A CrewAI oferece helpers para histórico de mensagens, classificação opcional de intenção, tracing adiado, pontes para UI e um REPL local `flow.chat()` para flows conversacionais.
Apps conversacionais tratam cada linha do usuário como uma **nova execução do flow** com o **mesmo id de sessão**. A CrewAI oferece helpers para histórico de mensagens, classificação opcional de intenção, tracing adiado e pontes para UI — sem uma API `chat()` separada em `Flow`.
| Conceito | Implementação |
|---------|----------------|
| Id de sessão | `handle_turn(..., session_id=...)` → `kickoff(inputs={"id": ...})` → `state.id` |
| Linha do usuário | `handle_turn(message)` acrescenta em `state.messages` antes do grafo rodar |
| Fim do turno | `FlowFinished` só para **esta execução**; o chat segue no próximo `handle_turn` |
| Trace da sessão | `ConversationConfig(defer_trace_finalization=True)` + `finalize_session_traces()` |
| Id de sessão | `kickoff(session_id=...)` → `inputs["id"]` → `state.id` |
| Linha do usuário | `kickoff(user_message=...)` acrescenta em `state.messages` antes do grafo rodar |
| Fim do turno | `FlowFinished` só para **esta execução**; o chat segue no próximo `kickoff` |
| Trace da sessão | `ConversationalConfig(defer_trace_finalization=True)` + `finalize_session_traces()` |
## APIs de turno
## Um ponto de entrada: `kickoff`
Use **`flow.handle_turn(message, session_id=...)`** para cada mensagem de usuário em REST, WebSocket, testes e UIs customizadas. Use **`flow.chat()`** quando quiser um loop de chat local no terminal para um `Flow` conversacional.
`Flow.kickoff()` não aceita os argumentos nomeados `user_message=` ou `session_id=`. Para flows conversacionais, `handle_turn()` guarda a mensagem pendente e chama `kickoff(inputs={"id": session_id})` internamente.
Use **`flow.kickoff(user_message=..., session_id=...)`** para cada mensagem (REST, WebSocket, CLI). Não crie um wrapper `chat()` customizado em `Flow`.
| API | Uso |
|-----|-----|
| `handle_turn(message, session_id=...)` | Wrapper ergonômico de um turno para `Flow` conversacional |
| `chat()` | REPL local no terminal para `Flow` conversacional |
| `kickoff(inputs={...})` | Execução avançada do flow sem tratamento de turno conversacional |
| `kickoff(user_message=..., session_id=...)` | Cada mensagem do usuário |
| `kickoff_async(...)` | Mesmos parâmetros; entrada async nativa |
| `ask()` | Prompt bloqueante **dentro** de um passo (wizard, esclarecimento) |
| `@human_feedback` | Aprovar/rejeitar **saída de um passo** — não a próxima linha do chat |
| `ChatSession.handle_turn(...)` | Camada de transporte sobre `handle_turn` (SSE / WebSocket) |
| `ChatSession.handle_turn(...)` | Camada de transporte sobre `kickoff` (SSE / WebSocket) |

Para um chat local no terminal, use `chat()`:

4. O router grava sua decisão em `state.last_intent` (visível para o contexto de routing do próximo turno).
5. Se seu handler retornou uma string e ainda não chamou `append_assistant_message`, `handle_turn` anexa para você.
Chame `handle_turn()` para mensagens de chat. Chamar `kickoff(inputs={"id": ...})` diretamente executa o grafo sem aplicar o wrapper de turno conversacional.
### `chat()` para REPLs locais
`flow.chat()` é o wrapper de terminal pronto para uso em cima de `handle_turn()`:
```python
flow = SupportFlow()
flow.chat()
```
Ele cobre o loop local comum:
1. Solicita uma mensagem do usuário.
2. Para com `exit` / `quit`, `EOFError` ou `KeyboardInterrupt`.
3. Chama `handle_turn(message, session_id=...)`.
4. Imprime o resultado do assistente.
5. Finaliza traces de sessão adiados em um bloco `finally`.
Customize o comportamento do terminal com I/O injetável:
```python
flow.chat(
session_id="demo-session",
prompt="You: ",
assistant_prefix="Assistant: ",
exit_commands=("exit", "quit", "bye"),
)
```
Para apps web, workers em background, testes e transportes customizados, continue usando `handle_turn()` diretamente.
Você também pode chamar `flow.kickoff(user_message=..., session_id=...)` diretamente — a mesma lógica de reset/run é acionada. `handle_turn` é o wrapper ergonômico.

"""Decorator for Flow methods that require human feedback.
This decorator wraps a Flow method to:
1. Execute the method and capture its output
2. Display the output to the human with a feedback request
3. Collect the human's free-form feedback
4. Optionally collapse the feedback to a predefined outcome using an LLM
5. Store the result for access by downstream methods
When `emit` is specified, the decorator acts as a router, and the
collapsed outcome triggers the appropriate @listen decorated method.
Supports both synchronous (blocking) and asynchronous (non-blocking)
feedback collection through the `provider` parameter. If no provider
is specified, defaults to synchronous console input.
Args:
message: The message shown to the human when requesting feedback.
This should clearly explain what kind of feedback is expected.
emit: Optional sequence of outcome strings. When provided, the
human's feedback will be collapsed to one of these outcomes
using the specified LLM. The outcome then triggers @listen
methods that match.
llm: The LLM model to use for collapsing feedback to outcomes.
Required when emit is specified. Can be a model string
like "gpt-4o-mini" or a BaseLLM instance.
default_outcome: The outcome to use when the human provides no
feedback (empty input). Must be one of the emit values
if emit is specified.
metadata: Optional metadata for enterprise integrations. This is
passed through to the HumanFeedbackResult and can be used
by enterprise forks for features like Slack/Teams integration.
provider: Optional HumanFeedbackProvider for custom feedback
collection. Use this for async workflows that integrate with
external systems like Slack, Teams, or webhooks. When the
provider raises HumanFeedbackPending, the flow pauses and
can be resumed later with Flow.resume().
learn: Enable HITL learning. Recall past lessons to pre-review
output before the human sees it, and distill new lessons
from feedback after.
learn_source: Memory source tag for stored/recalled lessons.
learn_strict: When True, re-raise exceptions from the pre-review
and distillation steps instead of falling back to raw output.
Default False preserves graceful degradation; failures are
always logged via ``logger.warning`` regardless of this flag.
Returns:
A decorator function that wraps the method with human feedback
collection logic.
Raises:
ValueError: If emit is specified but llm is not provided.
ValueError: If default_outcome is specified but emit is not.
ValueError: If default_outcome is not in the emit list.
HumanFeedbackPending: When an async provider pauses execution.
Example:
Basic feedback without routing:
```python
@start()
@human_feedback(message="Please review this output:")
def generate_content(self):
return "Generated content..."
```
With routing based on feedback:
```python
@start()
@human_feedback(
message="Review and approve or reject:",
emit=["approved", "rejected", "needs_revision"],
llm="gpt-4o-mini",
default_outcome="needs_revision",
)
def review_document(self):
return document_content
@listen("approved")
def publish(self):
print(f"Publishing: {self.last_human_feedback.output}")
```
Async feedback with custom provider:
```python
@start()
@human_feedback(
message="Review this content:",
emit=["approved", "rejected"],
llm="gpt-4o-mini",
provider=SlackProvider(channel="#reviews"),
)
