# Agent Instructions for CrewAI OSS
# Docs contributor guide
CrewAI is a Python based framework for building AI agents and agentic systems.
Follow these guidelines when contributing:
The `docs/` directory is published at [docs.crewai.com](https://docs.crewai.com)
by [Mintlify](https://www.mintlify.com/). Mintlify watches `docs/docs.json`
and the MDX files referenced from it.
## Key Guidelines
## TL;DR for editing docs
1. Follow Python best practices and idiomatic patterns.
2. Maintain existing code structure and organization.
3. Write unit tests for new functionality focusing on behaivor and not
implementation.
4. Document public APIs and complex logic.
5. Suggest changes to the `docs/` folder when appropriate
6. Follow software principles such as DRY and YAGNI.
7. Keep diffs as minimal as possible.
- Edit MDX under `docs/edge/<lang>/...` (e.g. `docs/edge/en/concepts/agents.mdx`).
- Your change ships under the **Edge** version selector the moment it merges
to `main`. Edge follows `main` and is the channel for unreleased work.
- On release cut, the current Edge state is frozen into `docs/v<X.Y.Z>/` and
that snapshot becomes the new default version in the selector (tag:
`Latest`). Canonical URLs (`/<lang>/...`) auto-redirect to the new default.
- Never modify files under `docs/v*/`. Those are frozen release snapshots
and the `docs-snapshots` CI guard rejects writes. The only exception is a
release-cut PR (auto-generated by `devtools release` or the manual
`scripts/docs/freeze_current_edge.py` wrapper), which uses a
`[docs-freeze]` title prefix to opt out.
- Never delete or rename files under `docs/images/`. Images are append-only.
See [Images](#images) below.
## Changing Docs
## The version model
1. Edit MDX under `docs/edge/en/*` and reference it from `docs/docs.json` if
needed.
2. Do not modify files under `docs/v*/`. Those are frozen release snapshots
managed by devtools.
3. Do not delete or rename files under `docs/images/` as frozen snapshots
may reference them.
4. If you want to preview your changes locally, use `cd docs && mintlify dev`.
To check for broken links, run `cd docs && mintlify broken-links`.
The site has one rolling channel (Edge) plus one frozen snapshot per
release.
```
docs/
edge/ <-- Edge sources (you edit here)
en/...
pt-BR/ ko/ ar/
enterprise-api.*.yaml
v1.14.7/ <-- frozen snapshot of v1.14.7
en/...
pt-BR/ ko/ ar/
enterprise-api.*.yaml
v1.14.6/...
...
images/ <-- shared, append-only
docs.json <-- Mintlify config: navigation + redirects
```
`docs/docs.json` lists one navigation block per version per language. Edge
points at `docs/edge/<lang>/...`; every other version points at its own
`docs/v<X.Y.Z>/<lang>/...` subtree. Mintlify scopes both the sidebar and the
in-site search to whichever version the reader selects, so picking
`v1.10.0` genuinely shows the v1.10.0 docs (and only those).
### URLs and canonical redirects
Each Mintlify version corresponds to its own URL prefix:
- Edge: `/edge/<lang>/<page>` (e.g. `/edge/en/concepts/agents`)
- Frozen: `/v<X.Y.Z>/<lang>/<page>` (e.g. `/v1.14.7/en/concepts/agents`)
External links to the old, unversioned `/<lang>/<page>` URLs would 404 under
this layout. To keep them working, `docs.json` ships wildcard redirects:
```jsonc
{ "source": "/en/:slug*", "destination": "/v1.14.7/en/:slug*", "permanent": false }
```
The release-cut step rewrites the destination on every release so canonical
`/<lang>/...` URLs always resolve to the latest stable docs.
## Lifecycle
1. **During development.** You add or edit pages under
`docs/edge/<lang>/...` in normal PRs. They land in Edge as soon as the PR
merges. Both `/edge/<lang>/<page>` and the version selector's `Edge` entry
reflect the change immediately.
2. **Release cut.** The release engineer runs `devtools release X.Y.Z`. As
part of that flow the CLI opens a `[docs-freeze]` PR that copies Edge into
`docs/v<X.Y.Z>/`, rewrites internal OpenAPI references, updates
`docs/docs.json` to make `v<X.Y.Z>` the new default + `Latest`, and rewires
the canonical-URL redirects to the new default. The PR must merge before
the tag and PyPI publish run.
3. **After release.** Edge keeps rolling. Patch fixes to the just-released
docs go into Edge and ship with the next release. We do not back-edit
frozen snapshots.
See [`RELEASING.md`](RELEASING.md) for the full release runbook.
## Images
Snapshots share a single `docs/images/` directory. If an image is deleted
or renamed, every frozen snapshot that referenced it breaks. So the rule
is:
- Adding new images is always fine.
- Deleting or renaming an existing image fails CI unless the PR is a
`[docs-freeze]` release-cut PR.
- If an asset is wrong, add a new file with a new name and reference the
new name in the Edge MDX (`docs/edge/<lang>/...`). Leave the old file
alone.
## Local preview
Install the Mintlify CLI and run from `docs/`:
```bash
npm i -g mintlify
mintlify dev
```
Use the version selector at the top of the rendered page to switch between
Edge and frozen versions.
To check links across every version:
```bash
mintlify broken-links
```
CI runs the broken-links check on every PR that touches `docs/**` via
[`.github/workflows/docs-broken-links.yml`](.github/workflows/docs-broken-links.yml).
## Scripts
- `scripts/docs/freeze_historical_versions.py` — one-time migration that
reconstructed `docs/v1.10.0/` through `docs/v1.14.7/` from git tags. You
should not need to run this again.
- `scripts/docs/prefix_version_paths.py` — one-time migration that switched
`docs/docs.json` to directory-based versioning, inserted Edge, and added
the canonical-URL redirects. You should not need to run this again.
- `scripts/docs/freeze_current_edge.py` — thin CLI wrapper around
`crewai_devtools.docs_versioning.freeze`. `devtools release` calls the
same module during its docs PR step; this script is the manual escape
hatch (e.g. retroactively freezing a forgotten release).
## CI guards
- [`.github/workflows/docs-snapshots.yml`](.github/workflows/docs-snapshots.yml)
enforces the two rules above (frozen snapshots immutable, images
append-only). Both checks accept the `[docs-freeze]` PR-title escape
hatch.
- [`.github/workflows/docs-broken-links.yml`](.github/workflows/docs-broken-links.yml)
runs `mintlify broken-links` against the whole site, so adding a new
page or moving a snapshot file that breaks a link will fail CI.

title: عقد بث وقت التشغيل
description: بث إطارات وقت تشغيل مرتبة من التدفقات واستدعاءات LLM المباشرة ودورات المحادثة.
icon: tower-broadcast
mode: "wide"
---
## نظرة عامة
يوفر CrewAI عقد بث قائمًا على الإطارات للأنظمة التي تحتاج إلى أكثر من أجزاء نصية بسيطة. يصدر العقد كائنات `StreamFrame` مرتبة لأحداث دورة حياة Flow، وتوكنات LLM المباشرة، ونشاط الأدوات، ورسائل المحادثة، والأحداث المخصصة.
استخدم هذه الواجهة عندما تبني واجهة مستخدم، أو جسر خدمة، أو تطبيق طرفية، أو وقت تشغيل نشر يحتاج إلى تدفق ثابت من الأحداث المهيكلة أثناء تشغيل Flow أو دورة محادثة أو استدعاء LLM مباشر.
## StreamFrame
لكل إطار نفس الغلاف:
```python
from crewai.types.streaming import StreamFrame
frame.id # معرف إطار فريد
frame.seq # ترتيب محلي للتنفيذ، عند توفره
frame.type # نوع الحدث المصدر، مثل "flow_started"
frame.channel # "llm", "flow", "tools", "messages", "lifecycle", or "custom"
frame.namespace # نطاق المصدر/وقت التشغيل
frame.timestamp # طابع وقت الحدث
frame.parent_id # معرف الحدث الأب، عند توفره
frame.previous_id # معرف الحدث السابق، عند توفره
frame.data # حمولة الحدث
frame.event # اسم بديل لـ frame.data
frame.content # نص قابل للطباعة لإطارات التوكن، وإلا ""
```
حقل `channel` هو أسرع طريقة لتوجيه الإطارات في المستهلكين:
| القناة | تحتوي على |
|--------|-----------|
| `llm` | توكنات وأجزاء التفكير من أحداث بث LLM |
| `flow` | دورة حياة Flow، وتنفيذ الدوال، والتوجيه، وأحداث الإيقاف/الاستئناف |
| `tools` | أحداث استخدام الأدوات |
| `messages` | أحداث سجل المحادثة |
| `lifecycle` | أحداث دورة حياة وقت التشغيل التي لا تخص قناة أخرى |
| `custom` | أحداث لا تُطابق قناة مدمجة |
يحافظ `frame.type` على نوع الحدث المصدر، حتى يتمكن المستهلكون من التعامل مع أحداث محددة داخل القناة.
## بث Flow
عيّن `stream=True` على Flow لجعل `kickoff()` يعيد جلسة stream:
```python
from crewai.flow import Flow, start
class ReportFlow(Flow):
@start()
def generate(self):
return "done"
flow = ReportFlow(stream=True)
stream = flow.kickoff()
with stream:
for chunk in stream:
print(chunk.content, end="", flush=True)
if chunk.type == "tool_usage_started":
print(chunk.event["tool_name"])
result = stream.result
```
يجب استهلاك stream قبل قراءة `stream.result`. يؤدي الوصول إلى النتيجة مبكرًا إلى رفع `RuntimeError` حتى لا يتعامل المستهلكون بالخطأ مع تشغيل جزئي على أنه مكتمل.
يمكنك أيضًا استدعاء `flow.stream_events(...)` مباشرة عندما تريد البث لاستدعاء واحد بدون تعيين `stream=True` على مثيل Flow.
## التصفية حسب القناة
يوفر `StreamSession` إسقاطات حسب القناة تحافظ على ترتيب الإطارات العالمي داخل القناة المحددة:
```python
stream = flow.stream_events()
with stream:
for frame in stream.llm:
print(frame.content, end="", flush=True)
result = stream.result
```
الإسقاطات المتاحة هي:
| الإسقاط | الإطارات |
|---------|----------|
| `stream.events` | كل الإطارات |
| `stream.llm` | إطارات LLM |
| `stream.messages` | إطارات رسائل المحادثة |
| `stream.flow` | إطارات Flow |
| `stream.tools` | إطارات الأدوات |
| `stream.interleave([...])` | مجموعة مختارة من القنوات |
استخدم `stream.interleave(["flow", "llm", "messages"])` عندما يريد المستهلك بعض القنوات فقط لكنه ما زال يحتاج إلى ترتيبها النسبي.
## البث غير المتزامن
استخدم `astream()` للمستهلكين غير المتزامنين:
```python
flow = ReportFlow()
stream = flow.astream()
async with stream:
async for chunk in stream.events:
print(chunk.channel, chunk.type, chunk.content)
result = stream.result
```
تملك الجلسة غير المتزامنة نفس إسقاطات الجلسة المتزامنة.
## بث استدعاء LLM مباشر
ما زال `llm.call(...)` يعيد النتيجة النهائية المجمعة. استخدم `llm.stream_events(...)` عندما تريد التكرار على الأجزاء فور وصولها مع الحفاظ على حمولة الحدث المهيكلة:
```python
from crewai import LLM
llm = LLM(model="gpt-4o-mini")
stream = llm.stream_events(
messages=[
{
"role": "user",
"content": "Explain CrewAI streaming in two short sentences.",
}
]
)
with stream:
for chunk in stream:
print(chunk.content, end="", flush=True)
result = stream.result
```
يفعل `llm.stream_events(...)` البث مؤقتًا للاستدعاء المغلف ثم يستعيد إعداد `stream` السابق في LLM بعد ذلك. تستمر تكاملات المزودين في إصدار أحداث بث LLM الأساسية؛ يوفر هذا المساعد واجهة مكرر مشتركة فوق تلك الأحداث لكل مزودي LLM.
## دورات المحادثة
يمكن للتدفقات المحادثية بث دورة مستخدم واحدة باستخدام `stream_turn()`:
```python
from crewai import Flow
from crewai.experimental.conversational import ConversationConfig, ConversationState
@ConversationConfig(llm="gpt-4o-mini", defer_trace_finalization=True)
class ChatFlow(Flow[ConversationState]):
conversational = True
flow = ChatFlow()
stream = flow.stream_turn("What can you help me with?", session_id="session-1")
with stream:
for frame in stream.events:
if frame.channel == "llm" and frame.type == "llm_stream_chunk":
print(frame.content, end="", flush=True)
reply = stream.result
```
أثناء `stream_turn()`، يفعّل مسار الإجابة المحادثية المدمج بث توكنات LLM لذلك الدور ثم يستعيد إعداد `stream` السابق في LLM بعد ذلك. يجب على معالجات المسارات المخصصة التي تنشئ Agents أو مثيلات LLM خاصة بها تهيئة تلك النماذج للبث إذا احتاجت إلى إخراج على مستوى التوكن.
## التنظيف
استخدم الجلسة كمدير سياق عندما يكون ذلك ممكنًا. إذا انقطع اتصال العميل قبل استهلاك stream بالكامل، فأغلق الجلسة صراحة:

title: Streaming
description: Understand CrewAI's streaming model for Flows, direct LLM calls, tools, and conversational turns.
icon: radio
mode: "wide"
---
## Overview
Streaming lets your application receive execution updates while work is still running. Instead of waiting for the final result, you can render LLM tokens, tool activity, Flow lifecycle events, and conversation messages as they happen.
CrewAI has two streaming surfaces:
| Surface | Used by | Output |
|---------|---------|--------|
| Frame streaming | Flows, direct LLM calls, conversational turns | Ordered `StreamFrame` objects |
| Crew chunk streaming | Crews with `stream=True` | `CrewStreamingOutput` chunks |
For new runtime integrations, UIs, terminal apps, service bridges, and conversational surfaces, use frame streaming. It provides one stable event envelope across the runtime.
## StreamFrame
A `StreamFrame` is the common object emitted by streamable runtimes:
```python
frame.id # unique frame id
frame.seq # execution-local order, when available
frame.type # source event type, such as "llm_stream_chunk"
frame.channel # "llm", "flow", "tools", "messages", "lifecycle", or "custom"
frame.namespace # source/runtime namespace
frame.timestamp # event timestamp
frame.parent_id # parent event id, when available
frame.previous_id # previous event id, when available
frame.data # structured event payload
frame.event # alias for frame.data
frame.content # printable text for token-like frames, otherwise ""
```
The important fields for most consumers are:
| Field | Use it for |
|-------|------------|
| `channel` | Routing frames to the right UI region |
| `type` | Handling a specific event inside a channel |
| `content` | Printing token-like text |
| `event` | Reading structured metadata, such as tool names or message roles |
| `seq` | Preserving execution order |
## Channels
Frames are grouped into high-level channels:
| Channel | Contains |
|---------|----------|
| `llm` | LLM call lifecycle, text chunks, and thinking chunks |
| `flow` | Flow lifecycle, method execution, routing, pause, and resume events |
| `tools` | Tool usage start, finish, and error events |
| `messages` | Conversation transcript events |
| `lifecycle` | Runtime lifecycle events that do not belong to another channel |
| `custom` | Events that do not map to a built-in channel |
The stream itself remains one ordered timeline. Channel projections let consumers focus on only part of that timeline.
```mermaid

A["flow<br/>flow_started"] --> B["llm<br/>llm_call_started"]

D --> E["tools<br/>tool_usage_finished"]
E --> F["llm<br/>llm_stream_chunk"]
F --> G["flow<br/>flow_finished"]
```
## Stream Sessions
Frame streaming returns a stream session:
```python
stream = flow.stream_events(inputs={"topic": "AI agents"})
```
The session is both an iterator and the holder for the final result:
```python
with stream:
for frame in stream:
print(frame.content, end="", flush=True)
result = stream.result
```
Consume the stream before reading `stream.result`. Reading the result too early raises an error because the runtime may still be producing frames.
## Channel Projections
Use channel projections when you only need one kind of frame:
```python
with flow.stream_events(inputs={"topic": "AI agents"}) as stream:
for frame in stream.llm:
print(frame.content, end="", flush=True)
result = stream.result
```
Available projections:
| Projection | Frames |
|------------|--------|
| `stream.events` | All frames |
| `stream.llm` | LLM frames |
| `stream.flow` | Flow frames |
| `stream.tools` | Tool frames |
| `stream.messages` | Conversation message frames |
| `stream.interleave([...])` | Selected channels in relative order |
## Entrypoints
Use the entrypoint that matches the runtime you are streaming:
| Runtime | Streaming entrypoint |
|---------|----------------------|
| Flow | `flow.stream_events(...)` |
| Flow with `stream=True` | `flow.kickoff(...)` returns a stream session |
| Async Flow | `flow.astream(...)` or `await flow.kickoff_async(...)` when `stream=True` |
| Direct LLM call | `llm.stream_events(...)` |
| Conversational Flow turn | `flow.stream_turn(...)` |
| Crew | `Crew(..., stream=True).kickoff(...)` returns `CrewStreamingOutput` |
Direct `llm.call(...)` still returns the final assembled LLM result. Use `llm.stream_events(...)` when you want to iterate over LLM chunks as they arrive.

## Streaming a turn
Use `stream_turn()` when a UI or runtime needs structured events for one chat turn. It returns a stream session with ordered frames for Flow routing, LLM chunks, tool activity, and conversation messages.
```python
stream = flow.stream_turn("Where is my order?", session_id=session_id)

title: Consuming Streams
description: Print LLM chunks, observe tool events, and read final results from CrewAI streams.
icon: square-terminal
mode: "wide"
---
## Overview
Use this guide when you want to subscribe to a CrewAI stream and print or route frames as they arrive.
The basic pattern is:
```python
stream = flow.stream_events(inputs={"topic": "AI agents"})
with stream:
for frame in stream:
...
result = stream.result
```
Always consume the stream before reading `stream.result`.
## Print LLM Output
If you only care about text generated by LLM calls, subscribe to the `llm` projection and print `frame.content`:
```python
stream = flow.stream_events(inputs={"topic": "AI agents"})
with stream:
for frame in stream.llm:
print(frame.content, end="", flush=True)
print()
result = stream.result
```
`frame.content` is an empty string for frames that do not carry printable text, so this is also safe:
```python
with flow.stream_events(inputs={"topic": "AI agents"}) as stream:
for frame in stream.events:
if frame.channel == "llm" and frame.content:
print(frame.content, end="", flush=True)
result = stream.result
```
## Print Tool Activity
Tool events arrive on the `tools` channel. Use `frame.type` to distinguish starts, finishes, and errors.
```python
with flow.stream_events(inputs={"topic": "AI agents"}) as stream:
for frame in stream.events:
if frame.channel == "llm" and frame.content:
print(frame.content, end="", flush=True)
if frame.channel == "tools" and frame.type == "tool_usage_started":
print(f"\nTool started: {frame.event.get('tool_name')}")
if frame.channel == "tools" and frame.type == "tool_usage_finished":
print(f"\nTool finished: {frame.event.get('tool_name')}")
result = stream.result
```
`frame.event` is the structured payload for the source event. Use it for metadata such as tool names, arguments, message roles, and runtime identifiers.
## Watch Flow Progress
Flow lifecycle and method execution frames arrive on the `flow` channel:
```python
with flow.stream_events(inputs={"topic": "AI agents"}) as stream:
for frame in stream.flow:
print(frame.type, frame.namespace)
result = stream.result
```
Use this when you want a progress log instead of token-level output.
## Interleave Selected Channels
Use `interleave()` when you want a subset of channels while preserving their relative order:
```python
with flow.stream_events(inputs={"topic": "AI agents"}) as stream:
for frame in stream.interleave(["llm", "tools"]):
if frame.channel == "llm":
print(frame.content, end="", flush=True)
elif frame.type == "tool_usage_started":
print(f"\nTool: {frame.event.get('tool_name')}")
result = stream.result
```
## Stream a Direct LLM Call
Direct `llm.call(...)` returns the final assembled result. To stream a direct LLM call, use `llm.stream_events(...)`:
```python
from crewai import LLM
llm = LLM(model="gpt-4o-mini")
stream = llm.stream_events("Explain streaming in one sentence.")
with stream:
for frame in stream.llm:
print(frame.content, end="", flush=True)
print()
result = stream.result
```
## Stream a Conversational Turn
Conversational Flows expose `stream_turn()` for one user message:
```python
stream = flow.stream_turn(
"What can you help me with?",
session_id="session-1",
)
with stream:
for frame in stream.interleave(["llm", "messages"]):
if frame.channel == "llm":
print(frame.content, end="", flush=True)
elif frame.channel == "messages":
print(f"\n{frame.event.get('role')}: {frame.event.get('content')}")
reply = stream.result
```
## Async Consumers
Async streams use the same channel projections:
```python
stream = flow.astream(inputs={"topic": "AI agents"})
async with stream:
async for frame in stream.llm:
print(frame.content, end="", flush=True)
result = stream.result
```
## Cleanup
Use the stream as a context manager when possible. If a client disconnects or you stop consuming early, close the stream:
```python
stream = flow.stream_events(inputs={"topic": "AI agents"})
try:
for frame in stream.events:
print(frame.content, end="", flush=True)
finally:
if not stream.is_exhausted:
stream.close()
```
For async streams, call `await stream.aclose()`.

title: Streaming Runtime Contract
description: Stream ordered runtime frames from Flows, direct LLM calls, and conversational turns.
icon: tower-broadcast
mode: "wide"
---
## Overview
CrewAI exposes a frame-based streaming contract for runtimes that need more than plain text chunks. The contract emits ordered `StreamFrame` objects for Flow lifecycle events, direct LLM tokens, tool activity, conversation messages, and custom events.
Use this API when you are building a UI, service bridge, terminal app, or deployment runtime that needs a stable stream of structured events while a Flow, chat turn, or direct LLM call is running.
## StreamFrame
Every frame has the same envelope:
```python
from crewai.types.streaming import StreamFrame
frame.id # unique frame id
frame.seq # execution-local order, when available
frame.type # source event type, such as "flow_started"
frame.channel # "llm", "flow", "tools", "messages", "lifecycle", or "custom"
frame.namespace # source/runtime namespace
frame.timestamp # event timestamp
frame.parent_id # parent event id, when available
frame.previous_id # previous event id, when available
frame.data # event payload
frame.event # alias for frame.data
frame.content # printable text for token-like frames, otherwise ""
```
The `channel` field is the fastest way to route frames in consumers:
| Channel | Contains |
|---------|----------|
| `llm` | Token and thinking chunks from LLM streaming events |
| `flow` | Flow lifecycle, method execution, routing, and pause/resume events |
| `tools` | Tool usage events |
| `messages` | Conversation transcript events |
| `lifecycle` | Runtime lifecycle events that are not specific to another channel |
| `custom` | Events that do not map to a built-in channel |
`frame.type` preserves the source event type, so consumers can handle specific events inside a channel.
## Stream a Flow
Set `stream=True` on a Flow to make `kickoff()` return a stream session:
```python
from crewai.flow import Flow, start
class ReportFlow(Flow):
@start()
def generate(self):
return "done"
flow = ReportFlow(stream=True)
stream = flow.kickoff()
with stream:
for chunk in stream:
print(chunk.content, end="", flush=True)
if chunk.type == "tool_usage_started":
print(chunk.event["tool_name"])
result = stream.result
```
You must consume the stream before reading `stream.result`. Accessing the result early raises a `RuntimeError` so consumers do not accidentally treat a partial run as complete.
You can also call `flow.stream_events(...)` directly when you want streaming for a single invocation without setting `stream=True` on the Flow instance.
## Filter by Channel
`StreamSession` exposes channel projections that preserve global frame order within the selected channel:
```python
stream = flow.stream_events()
with stream:
for frame in stream.llm:
print(frame.content, end="", flush=True)
result = stream.result
```
Available projections are:
| Projection | Frames |
|------------|--------|
| `stream.events` | All frames |
| `stream.llm` | LLM frames |
| `stream.messages` | Conversation message frames |
| `stream.flow` | Flow frames |
| `stream.tools` | Tool frames |
| `stream.interleave([...])` | A selected set of channels |
Use `stream.interleave(["flow", "llm", "messages"])` when a consumer wants only some channels but still needs their relative order.
## Async Streaming
Use `astream()` for async consumers:
```python
flow = ReportFlow()
stream = flow.astream()
async with stream:
async for chunk in stream.events:
print(chunk.channel, chunk.type, chunk.content)
result = stream.result
```
The async session has the same projections as the sync session.
## Stream a Direct LLM Call
`llm.call(...)` still returns the final assembled result. Use `llm.stream_events(...)` when you want to iterate over chunks as they arrive while keeping the structured event payload:
```python
from crewai import LLM
llm = LLM(model="gpt-4o-mini")
stream = llm.stream_events(
messages=[
{
"role": "user",
"content": "Explain CrewAI streaming in two short sentences.",
}
]
)
with stream:
for chunk in stream:
print(chunk.content, end="", flush=True)
result = stream.result
```
`llm.stream_events(...)` temporarily enables streaming for the wrapped call and restores the LLM's previous `stream` setting afterward. Provider integrations continue to emit the underlying LLM stream events; this helper provides a common iterator API over those events for every LLM provider.
## Conversational Turns
Conversational Flows can stream one user turn with `stream_turn()`:
```python
from crewai import Flow
from crewai.experimental.conversational import ConversationConfig, ConversationState
@ConversationConfig(llm="gpt-4o-mini", defer_trace_finalization=True)
class ChatFlow(Flow[ConversationState]):
conversational = True
flow = ChatFlow()
stream = flow.stream_turn("What can you help me with?", session_id="session-1")
with stream:
for frame in stream.events:
if frame.channel == "llm" and frame.type == "llm_stream_chunk":
print(frame.content, end="", flush=True)
reply = stream.result
```
During `stream_turn()`, the built-in conversational answer path enables LLM token streaming for that turn and restores the LLM's previous `stream` setting afterward. Custom route handlers that create their own agents or LLM instances should configure those LLMs for streaming if they need token-level output.
## Cleanup
Use the session as a context manager when possible. If a client disconnects before the stream is exhausted, close the session explicitly:
```python
stream = flow.stream_events()
try:
for frame in stream.events:
print(frame.type)
finally:
if not stream.is_exhausted:
stream.close()
```
For async streams, use `await stream.aclose()`.
## Legacy Chunk Streaming
Crew streaming with `stream=True` still returns the chunk-oriented `CrewStreamingOutput` API described in [Streaming Crew Execution](/en/learn/streaming-crew-execution). Direct `llm.call(...)` still returns the final LLM result. The frame contract is intended for runtimes that need a stable event envelope across Flows, direct LLM calls, conversational turns, tools, and messages.

title: 스트리밍 런타임 계약
description: Flow, 직접 LLM 호출, 대화 턴에서 정렬된 런타임 프레임을 스트리밍합니다.
icon: tower-broadcast
mode: "wide"
---
## 개요
CrewAI는 단순한 텍스트 청크보다 더 많은 정보가 필요한 런타임을 위해 프레임 기반 스트리밍 계약을 제공합니다. 이 계약은 Flow 생명주기 이벤트, 직접 LLM 토큰, 도구 활동, 대화 메시지, 사용자 지정 이벤트에 대해 정렬된 `StreamFrame` 객체를 방출합니다.
UI, 서비스 브리지, 터미널 앱, 배포 런타임을 만들 때 Flow, 채팅 턴, 직접 LLM 호출이 실행되는 동안 안정적인 구조화 이벤트 스트림이 필요하다면 이 API를 사용하세요.
## StreamFrame
모든 프레임은 같은 envelope를 가집니다:
```python
from crewai.types.streaming import StreamFrame
frame.id # 고유 프레임 id
frame.seq # 사용 가능한 경우 실행 로컬 순서
frame.type # "flow_started" 같은 원본 이벤트 타입
frame.channel # "llm", "flow", "tools", "messages", "lifecycle", "custom"
frame.namespace # 소스/런타임 namespace
frame.timestamp # 이벤트 timestamp
frame.parent_id # 사용 가능한 경우 부모 이벤트 id
frame.previous_id # 사용 가능한 경우 이전 이벤트 id
frame.data # 이벤트 payload
frame.event # frame.data의 alias
frame.content # 토큰류 프레임의 출력 가능한 텍스트, 그 외에는 ""
```
`channel` 필드는 소비자에서 프레임을 라우팅하는 가장 빠른 방법입니다:
| 채널 | 포함 내용 |
|------|-----------|
| `llm` | LLM 스트리밍 이벤트의 토큰 및 thinking 청크 |
| `flow` | Flow 생명주기, 메서드 실행, 라우팅, pause/resume 이벤트 |
| `tools` | 도구 사용 이벤트 |
| `messages` | 대화 transcript 이벤트 |
| `lifecycle` | 다른 채널에 속하지 않는 런타임 생명주기 이벤트 |
| `custom` | 내장 채널에 매핑되지 않는 이벤트 |
`frame.type`은 원본 이벤트 타입을 보존하므로, 소비자는 채널 안에서 특정 이벤트를 처리할 수 있습니다.
## Flow 스트리밍
Flow에 `stream=True`를 설정하면 `kickoff()`가 stream session을 반환합니다:
```python
from crewai.flow import Flow, start
class ReportFlow(Flow):
@start()
def generate(self):
return "done"
flow = ReportFlow(stream=True)
stream = flow.kickoff()
with stream:
for chunk in stream:
print(chunk.content, end="", flush=True)
if chunk.type == "tool_usage_started":
print(chunk.event["tool_name"])
result = stream.result
```
`stream.result`를 읽기 전에 stream을 소비해야 합니다. 결과를 너무 일찍 접근하면 `RuntimeError`가 발생하여, 소비자가 부분 실행을 완료된 실행으로 잘못 처리하지 않도록 합니다.
Flow 인스턴스에 `stream=True`를 설정하지 않고 단일 호출만 스트리밍하려면 `flow.stream_events(...)`를 직접 호출할 수도 있습니다.
## 채널별 필터링
`StreamSession`은 선택한 채널 안에서 전역 프레임 순서를 보존하는 채널 projection을 제공합니다:
```python
stream = flow.stream_events()
with stream:
for frame in stream.llm:
print(frame.content, end="", flush=True)
result = stream.result
```
사용 가능한 projection은 다음과 같습니다:
| Projection | 프레임 |
|------------|--------|
| `stream.events` | 모든 프레임 |
| `stream.llm` | LLM 프레임 |
| `stream.messages` | 대화 메시지 프레임 |
| `stream.flow` | Flow 프레임 |
| `stream.tools` | 도구 프레임 |
| `stream.interleave([...])` | 선택한 채널 집합 |
소비자가 일부 채널만 원하지만 상대 순서도 필요하다면 `stream.interleave(["flow", "llm", "messages"])`를 사용하세요.
## 비동기 스트리밍
비동기 소비자는 `astream()`을 사용하세요:
```python
flow = ReportFlow()
stream = flow.astream()
async with stream:
async for chunk in stream.events:
print(chunk.channel, chunk.type, chunk.content)
result = stream.result
```
비동기 세션은 동기 세션과 같은 projection을 제공합니다.
## 직접 LLM 호출 스트리밍
`llm.call(...)`은 계속 최종 조립 결과를 반환합니다. 구조화된 이벤트 payload를 유지하면서 청크가 도착하는 대로 반복 처리하려면 `llm.stream_events(...)`를 사용하세요:
```python
from crewai import LLM
llm = LLM(model="gpt-4o-mini")
stream = llm.stream_events(
messages=[
{
"role": "user",
"content": "Explain CrewAI streaming in two short sentences.",
}
]
)
with stream:
for chunk in stream:
print(chunk.content, end="", flush=True)
result = stream.result
```
`llm.stream_events(...)`는 감싼 호출 동안 일시적으로 streaming을 활성화하고, 이후 LLM의 이전 `stream` 설정을 복원합니다. provider 통합은 계속 기본 LLM stream 이벤트를 방출하며, 이 helper는 모든 LLM provider에서 그 이벤트 위에 공통 iterator API를 제공합니다.
## 대화 턴
대화형 Flow는 `stream_turn()`으로 사용자 턴 하나를 스트리밍할 수 있습니다:
```python
from crewai import Flow
from crewai.experimental.conversational import ConversationConfig, ConversationState
@ConversationConfig(llm="gpt-4o-mini", defer_trace_finalization=True)
class ChatFlow(Flow[ConversationState]):
conversational = True
flow = ChatFlow()
stream = flow.stream_turn("What can you help me with?", session_id="session-1")
with stream:
for frame in stream.events:
if frame.channel == "llm" and frame.type == "llm_stream_chunk":
print(frame.content, end="", flush=True)
reply = stream.result
```
`stream_turn()` 중에는 내장 대화 응답 경로가 해당 턴에 대해 LLM 토큰 스트리밍을 활성화하고 이후 LLM의 이전 `stream` 설정을 복원합니다. 자체 agent 또는 LLM 인스턴스를 만드는 사용자 지정 route handler는 토큰 단위 출력이 필요하다면 해당 LLM을 streaming으로 구성해야 합니다.
## 정리
가능하면 세션을 context manager로 사용하세요. stream이 끝나기 전에 클라이언트 연결이 끊기면 세션을 명시적으로 닫으세요:
```python
stream = flow.stream_events()
try:
for frame in stream.events:
print(frame.type)
finally:
if not stream.is_exhausted:
stream.close()
```
비동기 stream에서는 `await stream.aclose()`를 사용하세요.
## 레거시 청크 스트리밍
`stream=True`를 사용하는 Crew 스트리밍은 계속 [스트리밍 Crew 실행](/ko/learn/streaming-crew-execution)에 설명된 청크 중심 `CrewStreamingOutput` API를 반환합니다. 직접 `llm.call(...)` 호출도 계속 최종 LLM 결과를 반환합니다. 프레임 계약은 Flow, 직접 LLM 호출, 대화 턴, 도구, 메시지 전반에서 안정적인 이벤트 envelope가 필요한 런타임을 위한 것입니다.

title: Contrato de Streaming do Runtime
description: Transmita frames ordenados do runtime a partir de Flows, chamadas diretas de LLM e turnos conversacionais.
icon: tower-broadcast
mode: "wide"
---
## Visão geral
O CrewAI expõe um contrato de streaming baseado em frames para runtimes que precisam de mais do que chunks de texto simples. O contrato emite objetos `StreamFrame` ordenados para eventos de ciclo de vida de Flow, tokens de LLM diretos, atividade de ferramentas, mensagens de conversa e eventos personalizados.
Use esta API ao criar uma UI, ponte de serviço, aplicativo de terminal ou runtime de implantação que precise de um fluxo estável de eventos estruturados enquanto um Flow, turno de chat ou chamada direta de LLM está em execução.
## StreamFrame
Todo frame tem o mesmo envelope:
```python
from crewai.types.streaming import StreamFrame
frame.id # id único do frame
frame.seq # ordem local da execução, quando disponível
frame.type # tipo do evento de origem, como "flow_started"
frame.channel # "llm", "flow", "tools", "messages", "lifecycle" ou "custom"
frame.namespace # namespace de origem/runtime
frame.timestamp # timestamp do evento
frame.parent_id # id do evento pai, quando disponível
frame.previous_id # id do evento anterior, quando disponível
frame.data # payload do evento
frame.event # alias para frame.data
frame.content # texto imprimível para frames de token, caso contrário ""
```
O campo `channel` é a forma mais rápida de rotear frames em consumidores:
| Canal | Contém |
|-------|--------|
| `llm` | Tokens e chunks de raciocínio de eventos de streaming de LLM |
| `flow` | Ciclo de vida do Flow, execução de métodos, roteamento e eventos de pausa/retomada |
| `tools` | Eventos de uso de ferramentas |
| `messages` | Eventos do transcript da conversa |
| `lifecycle` | Eventos de ciclo de vida do runtime que não pertencem a outro canal |
| `custom` | Eventos que não mapeiam para um canal integrado |
`frame.type` preserva o tipo do evento de origem, para que consumidores possam tratar eventos específicos dentro de um canal.
## Transmitir um Flow
Defina `stream=True` em um Flow para fazer `kickoff()` retornar uma sessão de stream:
```python
from crewai.flow import Flow, start
class ReportFlow(Flow):
@start()
def generate(self):
return "done"
flow = ReportFlow(stream=True)
stream = flow.kickoff()
with stream:
for chunk in stream:
print(chunk.content, end="", flush=True)
if chunk.type == "tool_usage_started":
print(chunk.event["tool_name"])
result = stream.result
```
Você deve consumir o stream antes de ler `stream.result`. Acessar o resultado cedo demais gera um `RuntimeError`, para que consumidores não tratem uma execução parcial como concluída.
Você também pode chamar `flow.stream_events(...)` diretamente quando quiser streaming para uma única invocação sem definir `stream=True` na instância do Flow.
## Filtrar por canal
`StreamSession` expõe projeções por canal que preservam a ordem global dos frames dentro do canal selecionado:
```python
stream = flow.stream_events()
with stream:
for frame in stream.llm:
print(frame.content, end="", flush=True)
result = stream.result
```
As projeções disponíveis são:
| Projeção | Frames |
|----------|--------|
| `stream.events` | Todos os frames |
| `stream.llm` | Frames de LLM |
| `stream.messages` | Frames de mensagens de conversa |
| `stream.flow` | Frames de Flow |
| `stream.tools` | Frames de ferramentas |
| `stream.interleave([...])` | Um conjunto selecionado de canais |
Use `stream.interleave(["flow", "llm", "messages"])` quando um consumidor quiser apenas alguns canais, mas ainda precisar da ordem relativa entre eles.
## Streaming assíncrono
Use `astream()` para consumidores assíncronos:
```python
flow = ReportFlow()
stream = flow.astream()
async with stream:
async for chunk in stream.events:
print(chunk.channel, chunk.type, chunk.content)
result = stream.result
```
A sessão assíncrona tem as mesmas projeções da sessão síncrona.
## Transmitir uma chamada direta de LLM
`llm.call(...)` ainda retorna o resultado final montado. Use `llm.stream_events(...)` quando quiser iterar pelos chunks conforme eles chegam, mantendo o payload estruturado do evento:
```python
from crewai import LLM
llm = LLM(model="gpt-4o-mini")
stream = llm.stream_events(
messages=[
{
"role": "user",
"content": "Explain CrewAI streaming in two short sentences.",
}
]
)
with stream:
for chunk in stream:
print(chunk.content, end="", flush=True)
result = stream.result
```
`llm.stream_events(...)` ativa temporariamente o streaming para a chamada encapsulada e restaura a configuração anterior de `stream` do LLM depois. As integrações de provedores continuam emitindo os eventos de stream de LLM subjacentes; esse helper fornece uma API de iterador comum sobre esses eventos para todos os provedores de LLM.
## Turnos conversacionais
Flows conversacionais podem transmitir um turno de usuário com `stream_turn()`:
```python
from crewai import Flow
from crewai.experimental.conversational import ConversationConfig, ConversationState
@ConversationConfig(llm="gpt-4o-mini", defer_trace_finalization=True)
class ChatFlow(Flow[ConversationState]):
conversational = True
flow = ChatFlow()
stream = flow.stream_turn("What can you help me with?", session_id="session-1")
with stream:
for frame in stream.events:
if frame.channel == "llm" and frame.type == "llm_stream_chunk":
print(frame.content, end="", flush=True)
reply = stream.result
```
Durante `stream_turn()`, o caminho de resposta conversacional integrado ativa o streaming de tokens de LLM para esse turno e restaura a configuração anterior de `stream` do LLM depois. Handlers de rota personalizados que criam seus próprios agentes ou instâncias de LLM devem configurar esses LLMs para streaming se precisarem de saída em nível de token.
## Limpeza
Use a sessão como gerenciador de contexto quando possível. Se um cliente se desconectar antes de o stream ser esgotado, feche a sessão explicitamente:
```python
stream = flow.stream_events()
try:
for frame in stream.events:
print(frame.type)
finally:
if not stream.is_exhausted:
stream.close()
```
Para streams assíncronos, use `await stream.aclose()`.
## Streaming de chunks legado
O streaming de Crew com `stream=True` ainda retorna a API orientada a chunks `CrewStreamingOutput` descrita em [Streaming da Execução de Crew](/pt-BR/learn/streaming-crew-execution). Chamadas diretas `llm.call(...)` ainda retornam o resultado final do LLM. O contrato de frames é destinado a runtimes que precisam de um envelope de evento estável em Flows, chamadas diretas de LLM, turnos conversacionais, ferramentas e mensagens.

# Flow Definition
You are writing a CrewAI Flow declaration for the user.
Use these instructions when the user asks you to create or edit a Flow.
Return one valid `crewai.flow/v1` YAML or JSON document.
Treat this document as instructions for you, not as text to show the user.
Follow the examples for shape and formatting, then use the API reference to check exact fields.
## Output Format
Return one valid `crewai.flow/v1` Flow declaration.
Do not include explanatory prose unless the user asks for it.
## Build It In This Order
1. Define `state` first. Use `type: json_schema` and put the JSON Schema inline.
2. Put required input fields in `state.json_schema.required`. Do not rely on `state.default` to make fields required.
3. Add exactly one method with `start: true`.
4. Add later methods with `listen`.
5. Give each method exactly one `do` action object. Never make `do` a list.
6. Pass data with `${...}` mappings from `state` and completed `outputs`.
7. Before final output, check every `listen`, `emit`, and `outputs.some_method` reference.
Set optional fields only when you are confident they are needed. Otherwise, trust CrewAI defaults and omit them.
Method names must match `^[A-Za-z_][A-Za-z0-9_]*$`.
## Choose One Action Per Method
Pick the simplest action that does the job.
- Use `call: expression` for simple reads, filters, computed values, and deterministic routing.
- Use `call: agent` for one AI worker that classifies, decides, summarizes, writes, or drafts. Put `role`, `goal`, `backstory`, and `input` under `with`. Do not add an action-level `inputs` map to an agent.
- Use `call: crew` for coordinated AI work with multiple agents or tasks. Define the crew under `with`. Pass runtime values with the action-level `inputs` map.
## Wire Methods Explicitly
- `state` is the initial shared data shape. Action results do not automatically merge into `state`.
- Read method results with `outputs.method_name` after that method can run.
- `listen` targets a method name or a router-emitted event name.
- Methods must not listen to their own method name.
- Method names and emitted event names share one namespace. Avoid reusing the same string for both unless the user explicitly wants that.
- Use `router: true` plus `emit` when one method chooses between named branches.
- A router action must return exactly one emitted event string. It must not return JSON, a list, or an explanation.
- Use `start: true` for the single entrypoint.
If an agent is a router, make its goal say exactly what to return, for example:
`Return exactly one bare value: approved, rejected, or needs_review. Do not include explanation.`
Prefer `call: expression` when routing can be computed without an agent.
## CEL And Dynamic Values
CEL is the expression language for reading Flow data and making small decisions.
Use agents and crews for larger work or side effects.
Use these expression forms correctly:
- Raw CEL: use in `expr`. Do not wrap raw CEL in `${...}`.
- Use `${...}` inside action mapping strings to read Flow data with CEL. Example value: `Ticket: ${state.ticket_id}`.
- Use `state` for input data. Use `outputs.step_name` for a completed method result.
- If a value is only one `${...}` expression, the result keeps its type. Use this for numbers, booleans, objects, and lists.
- If the string has other text, the final value is text. Non-text values become JSON. `null` becomes empty text.
- Use `text(root, "path", "default")` for values that may be missing or null. The default is optional and is `""`.
Expression examples:
Mix text and Flow data:
```yaml
query: "News about ${state.topic}"
```
Keep a list or number type:
```yaml
domains: "${state.domains}"
limit: "${state.limit}"
```
Use a default for missing text:
```yaml
input: "Ticket ${text(state, \"ticket.id\", \"unknown\")}"
```
- Crew text: use `{name}` placeholders from crew inputs. Example: `Research {topic}`.
- Crew inputs become prompt text only when agent or task text references matching `{name}` placeholders.
- Passing an input that is not referenced by any `{name}` placeholder does not ground the crew. If the crew needs a field, put that placeholder in an agent `goal`, task `description`, or task `expected_output`.
Available CEL variables:
- `state`: initial input data, for example `state.ticket.subject`.
- `outputs`: completed method outputs, for example `outputs.classify_ticket`.
Dynamic value rules:
- When an agent needs multiple fields, write one text value with labels and separators. Example value: `Ticket ID: ${state.ticket_id}; Message: ${state.message}`.
- Crew action-level `inputs` are the actual Crew kickoff inputs. Use `${...}` values there for runtime data from `state` or `outputs`.
- Crew action-level `inputs` alone are not grounding. Include placeholders for the facts the model must use.
- Crew outputs are objects. Use `${outputs.research_brief.raw}` for text.
- For structured crew output, use fields like `${outputs.research_brief.json_dict.field}` or `${outputs.research_brief.pydantic.field}`.
- Do not pass a whole crew output to an agent input, like `${outputs.research_brief}`.
- Agent outputs may also be objects. Use fields like `${outputs.classify_ticket.raw}` or `${outputs.classify_ticket.pydantic.category}`.
- Use `with.inputs` only for static Crew input defaults.
- Agent action `with.input` is the agent's single input value.
## Do Not
- Do not invent top-level keys outside the Flow declaration shape.
- Do not use fields outside the declaration schema.
- Do not put more than one action under a method's `do`.
- Do not make `do` a list.
- Do not reference `outputs.some_method` before `some_method` can run.
- Do not set a method's `listen` to its own method name.
- Do not use the same string for an emitted event and a method name unless the user asks for it.
- Do not use `emit` without `router: true`.
- Do not rely on crew action-level `inputs` alone to ground agent behavior. Inputs that do not match placeholders are effectively unused by the prompt.
- Do not ask agents to infer missing facts when accuracy matters. Tell them to mark missing dates, amounts, offers, logs, or constraints as unknown.
- Do not set `config.stream: true` unless the caller is expected to consume a streaming result. For normal generated flows and CLI smoke tests, omit it.

## API Reference
Use this appendix to check exact field names, required fields, linked object types, and allowed action/state shapes. Linked type names point to another section in this reference.
### Flow Definition
Fields:
- `schema` (optional): must be `crewai.flow/v1`; default `crewai.flow/v1`. Declarative Flow schema identifier and version. Include it explicitly in authored declarations.
- `name` (required): string. Unique flow name used in logs, events, and traces.
- `description` (optional): string | null; default `null`. Human-readable summary of the flow.
- `state` (required): [State](#json-schema-state-statetypejson_schema). State contract for the initial state and updates during execution.
- `config` (optional): [Config (`config`)](#config-config); default generated default. Serializable flow-level execution configuration.
- `methods` (required): map of string to [Method](#method-methods). Mapping of method names to method definitions.
### JSON Schema State (`state[type=json_schema]`)
Shape:
- `type: json_schema`
Fields:
- `type` (optional): must be `json_schema`; default `json_schema`. Inline JSON Schema used as the Flow state contract.
- `json_schema` (required): map of string to any. JSON Schema used to validate and document flow state. Declare required fields with JSON Schema's `required` array.
- `default` (optional): map of string to any | null; default `null`. Default values used to initialize Flow state. Defaults are not the same as schema-required fields.
### Method (`methods.<name>`)
Fields:
- `description` (optional): string | null; default `null`. Human-readable summary of what this method does.
- `do` (required): [Action](#action). Single action object executed when this method runs.
- `start` (optional): boolean | string | map of string to any | null; default `null`. Marks the single normal entrypoint. Use `true`.
- `listen` (optional): string | map of string to any | null; default `null`. Runs this method after one upstream method or router-emitted event.
- `router` (optional): boolean; default `false`. Whether the method output should be treated as the next event name. Router actions must return one event name string, with no surrounding explanation.
- `emit` (optional): list[string] | null; default `null`. Declared router events this method may emit. Each emitted event name should be unique and should not collide with method names.
### Action
Discriminated union by `call`.
Allowed shapes:
- [`call: crew`](#crew-action-methodsdocallcrew)
- [`call: agent`](#agent-action-methodsdocallagent)
- [`call: expression`](#expression-action-methodsdocallexpression)
### Crew Action (`methods.<name>.do[call=crew]`)
Shape:
- `call: crew`
Fields:
- `call` (required): must be `crew`. Action discriminator. Use crew to run an inline Crew definition. Example: `crew`
- `with` (required): inline crew definition. Inline Crew definition to load and execute for this action. Example: `{"agents": {"researcher": {"backstory": "Knows the domain.", "goal": "Research {topic}", "role": "Researcher"}}, "name": "inline_research", "tasks": [{"agent": "researcher", "description": "Research {topic}", "expected_output": "Findings about {topic}", "name": "research_task"}]}`
- `inputs` (optional): map of string to expression data | null; default `null`. Actual kickoff inputs passed to the Crew. Use `${...}` inside action mapping strings to read Flow data with CEL. Example value: `Ticket: ${state.ticket_id}`. Use `state` for input data. Use `outputs.step_name` for a completed method result. If a value is only one `${...}` expression, the result keeps its type. Use this for numbers, booleans, objects, and lists. If the string has other text, the final value is text. Non-text values become JSON. `null` becomes empty text. Use `text(root, "path", "default")` for values that may be missing or null. The default is optional and is `""`. The evaluated values are available to crew agent and task interpolation as `{name}` placeholders; reference each input the crew needs in agent or task text. Example: `{"topic": "${state.topic}"}`
#### Crew Definition (`methods.<name>.do[call=crew].with`)
Fields:
- `agents` (required): map of string to any | list[map of string to any]. Inline crew agents keyed by agent name. Example: `{"researcher": {"backstory": "Expert at concise technical research.", "goal": "Research {topic}", "role": "Research analyst"}}`

- `inputs` (optional): map of string to any. Static default crew inputs. Values are available to crew agent and task interpolation as `{name}` placeholders, for example `{topic}`. Prefer action-level crew `inputs` for runtime values from `state` or `outputs`, and include placeholders for any inputs the crew must reason over. Example: `{"topic": "AI agents"}`
#### Crew Agent Definition (`methods.<name>.do[call=crew].with.agents.<name>`)

- `tools` (optional): list[string | map of string to any] | null; default `null`. Tool refs or serialized tool definitions available to this agent. String refs can use CrewAI tool names, `custom:<name>`, or fully qualified `module:Class` references. Example: `["crewai_tools:SerperDevTool", "custom:file_read"]`
- `apps` (optional): list[string] | null; default `null`. Platform apps available to this agent. Can contain app names such as `gmail` or app/action refs such as `gmail/send_email`. Example: `["gmail", "slack/send_message"]`
- `mcps` (optional): list[string | map of string to any] | null; default `null`. MCP server refs or serialized MCP server configs available to this agent.

String refs can use CrewAI tool names, `custom:<name>`, or fully qualified `module:Class` references. Example: `["crewai_tools:SerperDevTool", "custom:file_read"]`
- `apps` (optional): list[string] | null; default `null`. Platform apps available to this agent. Can contain app names such as `gmail` or app/action refs such as `gmail/send_email`. Example: `["gmail", "slack/send_message"]`

Example: `["https://api.weather.com/mcp#get_current_weather", "snowflake", "stripe#list_invoices", {"cache_tools_list": true, "headers": {"Authorization": "Bearer your_token"}, "streamable": true, "url": "https://api.example.com/mcp"}]`
- `input` (required): string. Input passed to the individual agent kickoff outside of a crew. Use one string. Use `${...}` inside action mapping strings to read Flow data with CEL. Example value: `Ticket: ${state.ticket_id}`. Use `state` for input data. Use `outputs.step_name` for a completed method result. If a value is only one `${...}` expression, the result keeps its type. Use this for numbers, booleans, objects, and lists. If the string has other text, the final value is text. Non-text values become JSON. `null` becomes empty text. Use `text(root, "path", "default")` for values that may be missing or null. The default is optional and is `""`. When an agent needs multiple fields, write one string with labels and separators, for example `Ticket ID: ${state.ticket_id}; Message: ${state.message}`. Example: `${state.ticket.body}`
#### LLM Definition
Fields:
- `model` (required): string. Model identifier used to instantiate the LLM. Example: `openai/gpt-4o-mini`
- `max_tokens` (optional): integer | null; default `null`. Maximum number of tokens the LLM can generate. If null, CrewAI does not set an explicit output token cap and the provider's default applies. Example: `4096`
### Expression Action (`methods.<name>.do[call=expression]`)
Shape:
- `call: expression`
Fields:
- `call` (required): must be `expression`. Action discriminator. Use expression to evaluate a CEL expression.
- `expr` (required): string. CEL expression evaluated against state, outputs, and local context.
### Config (`config`)
Fields:
- `tracing` (optional): boolean | null; default `null`. Override for flow tracing; when omitted, execution defaults apply.
- `stream` (optional): boolean; default `false`. Whether the flow should emit streaming events when supported.
- `memory` (optional): map of string to any | null; default `null`. Serializable memory configuration passed to flow execution.
- `input_provider` (optional): string | null; default `null`. Provider key used to supply initial state.
- `suppress_flow_events` (optional): boolean; default `false`. Disable flow event emission for this definition.
- `max_method_calls` (optional): integer; default `100`. Maximum number of method executions allowed during one kickoff.
- `defer_trace_finalization` (optional): boolean; default `false`. Defer trace finalization so callers can complete tracing later.
- `checkpoint` (optional): boolean | map of string to any | null; default `null`. Checkpointing configuration, or true to use default checkpointing.
### Cross-Field Rules
- A method has exactly one `do` action object with one `call` discriminator.
- `listen` targets method names and router-emitted event names in one shared namespace.
- Methods cannot listen to their own method name.
- A router method result must match one declared `emit` value.
- Crew action-level `inputs` are the Crew kickoff inputs; use CEL-wrapped strings there for runtime values.
- Crew agent/task interpolation uses `{name}` placeholders from evaluated crew inputs.
- Agent `with.input` must be text. Use `${outputs.method_name.raw}` or a text field like `${outputs.method_name.json_dict.summary}`.

name: flow-definition
description: Create or edit CrewAI Flow declarations. Use when the user needs a YAML or JSON flow with methods, state, agents, crews, tools, outputs, or conditional branches.
---
# Flow Definition
You are writing a CrewAI Flow declaration for the user.
Use these instructions when the user asks you to create or edit a Flow.
Return one valid `crewai.flow/v1` YAML or JSON document.
Treat this document as instructions for you, not as text to show the user.
Follow the examples for shape and formatting, then use the API reference to check exact fields.
## Output Format
Return one valid `crewai.flow/v1` Flow declaration.
Do not include explanatory prose unless the user asks for it.
## Build It In This Order
1. Define `state` first. Use `type: json_schema` and put the JSON Schema inline.
2. Put required input fields in `state.json_schema.required`. Do not rely on `state.default` to make fields required.
{% if include_non_linear_flows %}
3. Add at least one method with `start: true`.
{% else %}
3. Add exactly one method with `start: true`.
{% endif %}
4. Add later methods with `listen`.
5. Give each method exactly one `do` action object. Never make `do` a list.
6. Pass data with `${...}` mappings from `state` and completed `outputs`.
7. Before final output, check every `listen`, `emit`, and `outputs.some_method` reference.
Set optional fields only when you are confident they are needed. Otherwise, trust CrewAI defaults and omit them.
Method names must match `^[A-Za-z_][A-Za-z0-9_]*$`.
## Choose One Action Per Method
Pick the simplest action that does the job.
{% if include_expression_action %}
- Use `call: expression` for simple reads, filters, computed values, and deterministic routing.
{% endif %}
{% if include_tool_action %}
- Use `call: tool` for packaged deterministic work: API calls, searches, lookups, scoring, file work, or custom CrewAI tools.
{% endif %}
- Use `call: agent` for one AI worker that classifies, decides, summarizes, writes, or drafts. Put `role`, `goal`, `backstory`, and `input` under `with`. Do not add an action-level `inputs` map to an agent.
- Use `call: crew` for coordinated AI work with multiple agents or tasks. Define the crew under `with`. Pass runtime values with the action-level `inputs` map.
{% if include_each_action %}
- Use `call: each` when the same ordered mini-pipeline must run once per item. Give every step a `name`.
{% endif %}
{% if include_hitl %}
- Use `human_feedback` when a method needs a human checkpoint.
{% endif %}
{% if include_script_action %}
- Use `call: script` only for trusted inline Python. Scripts are not sandboxed.
{% endif %}
## Wire Methods Explicitly
- `state` is the initial shared data shape. Action results do not automatically merge into `state`.
- Read method results with `outputs.method_name` after that method can run.
- `listen` targets a method name or a router-emitted event name.
- Methods must not listen to their own method name.
- Method names and emitted event names share one namespace. Avoid reusing the same string for both unless the user explicitly wants that.
- Use `router: true` plus `emit` when one method chooses between named branches.
- A router action must return exactly one emitted event string. It must not return JSON, a list, or an explanation.
{% if include_non_linear_flows %}
- Conditional `listen` values use `and` / `or`, for example `listen: {and: [validated, enriched]}`. They are not CEL.
- Use `start: true` for normal entrypoints. Use conditional `start` only for advanced event-driven starts.
{% else %}
- Use `start: true` for the single entrypoint.
{% endif %}
If an agent is a router, make its goal say exactly what to return, for example:
`Return exactly one bare value: approved, rejected, or needs_review. Do not include explanation.`
{% if include_expression_action %}
Prefer `call: expression` when routing can be computed without an agent.
{% endif %}
## CEL And Dynamic Values
CEL is the expression language for reading Flow data and making small decisions.
Use {% if include_tool_action %}tools, {% endif %}agents and crews{% if include_script_action %}, or trusted scripts{% endif %} for larger work or side effects.
Use these expression forms correctly:
{% if include_expression_action or include_each_action %}
- Raw CEL: use in {% if include_expression_action and include_each_action %}`expr`, `in`, and `if`{% elif include_expression_action %}`expr`{% else %}`in` and `if`{% endif %}. Do not wrap raw CEL in `${...}`.
{% endif %}
{% for rule in expression_contract_rules %}
- {{ rule }}
{% endfor %}
Expression examples:
{% for example in expression_contract_examples %}
{{ example.title }}:
```{{ example_language }}
{{ example.code }}
```
{% endfor %}
- Crew text: use `{name}` placeholders from crew inputs. Example: `Research {topic}`.
- Crew inputs become prompt text only when agent or task text references matching `{name}` placeholders.
- Passing an input that is not referenced by any `{name}` placeholder does not ground the crew. If the crew needs a field, put that placeholder in an agent `goal`, task `description`, or task `expected_output`.
Available CEL variables:
- `state`: initial input data, for example `state.ticket.subject`.
- `outputs`: completed method outputs, for example `outputs.classify_ticket`.
{% if include_each_action %}
- `item`: the current item inside `each`, for example `item.company_domain`.
- `outputs`: inside `each`, prior step outputs for the current item, for example `outputs.enrich`.
{% endif %}
Dynamic value rules:
- When an agent needs multiple fields, write one text value with labels and separators. Example value: `Ticket ID: ${state.ticket_id}; Message: ${state.message}`.
- Crew action-level `inputs` are the actual Crew kickoff inputs. Use `${...}` values there for runtime data from `state` or `outputs`.
- Crew action-level `inputs` alone are not grounding. Include placeholders for the facts the model must use.
- Crew outputs are objects. Use `${outputs.research_brief.raw}` for text.
- For structured crew output, use fields like `${outputs.research_brief.json_dict.field}` or `${outputs.research_brief.pydantic.field}`.
- Do not pass a whole crew output to an agent input, like `${outputs.research_brief}`.
- Agent outputs may also be objects. Use fields like `${outputs.classify_ticket.raw}` or `${outputs.classify_ticket.pydantic.category}`.
- Use `with.inputs` only for static Crew input defaults.
- Agent action `with.input` is the agent's single input value.
{% if include_script_action %}
- Trusted `script` actions can mutate state explicitly. Use them only when the user asks for that behavior.
{% endif %}
## Do Not
- Do not invent top-level keys outside the Flow declaration shape.
- Do not use fields outside the declaration schema{% if include_tool_action %} or tool refs shown here{% endif %}.
- Do not put more than one action under a method's `do`.
- Do not make `do` a list.
- Do not reference `outputs.some_method` before `some_method` can run.
- Do not set a method's `listen` to its own method name.
- Do not use the same string for an emitted event and a method name unless the user asks for it.
- Do not use `emit` without `router: true`{% if include_hitl %} or `human_feedback.emit`{% endif %}.
- Do not rely on crew action-level `inputs` alone to ground agent behavior. Inputs that do not match placeholders are effectively unused by the prompt.
- Do not ask agents to infer missing facts when accuracy matters. Tell them to mark missing dates, amounts, offers, logs, or constraints as unknown.
- Do not set `config.stream: true` unless the caller is expected to consume a streaming result. For normal generated flows and CLI smoke tests, omit it.
{% if include_conversational %}
- Do not put conversational settings under `state`, `config`, or a method. Use top-level `conversational` only when the user asks for a chat or conversation flow.
{% endif %}
{% if include_each_action %}
- Do not use `each` without at least one named step.
{% endif %}
{% if include_script_action %}
- Do not use `script` for untrusted input or user-authored code.
{% endif %}

{% endfor %}
{% for inline_model in model.inline_models %}
#### {{ inline_model.label }}
{{ render_model(inline_model) }}
{% endfor %}
{%- endmacro %}
{% for section in sections %}
### {{ section.label }}
{% if section.kind == "union" %}
Discriminated union by `{% if section.label == "State" %}type{% else %}call{% endif %}`.
Allowed shapes:
{% for model in section.models %}
- [`{{ model.discriminator.name }}: {{ model.discriminator.value }}`]({{ model.anchor }})
{% endfor %}
{% for model in section.models %}
### {{ model.label }}
{{ render_model(model) }}
{% endfor %}
{% else %}
{{ render_model(section.models[0]) }}
{% endif %}
{% endfor %}
### Cross-Field Rules
- A method has exactly one `do` action object with one `call` discriminator.
- `listen` targets method names and router-emitted event names in one shared namespace.
- Methods cannot listen to their own method name.
- A router method result must match one declared `emit` value.
- Crew action-level `inputs` are the Crew kickoff inputs; use CEL-wrapped strings there for runtime values.
- Crew agent/task interpolation uses `{name}` placeholders from evaluated crew inputs.
- Agent `with.input` must be text. Use `${outputs.method_name.raw}` or a text field like `${outputs.method_name.json_dict.summary}`.
{% if include_each_action %}
- `each.do` must contain at least one named step.
{% endif %}
