ad82e52d39 fix(gemini): group parallel function_response parts in a single Content object (#4693)
* fix(gemini): group parallel function_response parts in a single Content object

When Gemini makes N parallel tool calls, the API requires all N function_response parts in one Content object. Previously each tool result created a separate Content, causing 400 INVALID_ARGUMENT errors. Merge consecutive function_response parts into the existing Content instead of appending new ones.

* Address change requested

- function_response is a declared field on the types.Part Pydantic model so hasattr can be replaced with p.function_response is not None

b76022c1e7 fix(telemetry): skip signal handler registration in non-main threads
* fix(telemetry): skip signal handler registration in non-main threads

When CrewAI is initialized from a non-main thread (e.g. Streamlit, Flask,
Django, Jupyter), the telemetry module attempted to register signal handlers
which only work in the main thread. This caused multiple noisy ValueError
tracebacks to be printed to stderr, confusing users even though the errors
were caught and non-fatal.

Check `threading.current_thread() is not threading.main_thread()` before
attempting signal registration, and skip silently with a debug-level log
message instead of printing full tracebacks.

Fixes crewAIInc/crewAI#4289

* fix(test): move Telemetry() inside signal.signal mock context

Refs: #4649

* fix(telemetry): move signal.signal mock inside thread to wrap Telemetry() construction

The patch context now activates inside init_in_thread so the mock
is guaranteed to be active before and during Telemetry.__init__,
addressing the Copilot review feedback.

Refs: #4289

* fix(test): mock logger.debug instead of capsys for deterministic assertion

Replace signal.signal-only mock with combined logger + signal mock.
Assert logger.debug was called with the skip message and signal.signal
was never invoked from the non-main thread.

09e3b81ca3 fix: preserve null types in tool parameter schemas for LLM (#4579)
* fix: preserve null types in tool parameter schemas for LLM

Tool parameter schemas were stripping null from optional fields via
generate_model_description, forcing the LLM to provide non-null values
for fields.
Adds strip_null_types parameter to generate_model_description and passes False when generating tool
schemas, so optional fields keep anyOf: [{type: T}, {type: null}]

* Update lib/crewai/src/crewai/utilities/pydantic_schema_utils.py

a6dcb275e1 Lorenze/feat planning pt 2 todo list gen (#4449)
* feat: introduce PlanningConfig for enhanced agent planning capabilities

This update adds a new PlanningConfig class to manage agent planning configurations, allowing for customizable planning behavior before task execution. The existing reasoning parameter is deprecated in favor of this new configuration, ensuring backward compatibility while enhancing the planning process. Additionally, the Agent class has been updated to utilize this new configuration, and relevant utility functions have been adjusted accordingly. Tests have been added to validate the new planning functionality and ensure proper integration with existing agent workflows.

* dropping redundancy

* fix test

* revert handle_reasoning here

* refactor: update reasoning handling in Agent class

This commit modifies the Agent class to conditionally call the handle_reasoning function based on the executor class being used. The legacy CrewAgentExecutor will continue to utilize handle_reasoning, while the new AgentExecutor will manage planning internally. Additionally, the PlanningConfig class has been referenced in the documentation to clarify its role in enabling or disabling planning. Tests have been updated to reflect these changes and ensure proper functionality.

* improve planning prompts

* matching

* refactor: remove default enabled flag from PlanningConfig in Agent class

* more cassettes

* fix test

* feat: enhance agent planning with structured todo management

This commit introduces a new planning system within the AgentExecutor class, allowing for the creation of structured todo items from planning steps. The TodoList and TodoItem models have been added to facilitate tracking of plan execution. The reasoning plan now includes a list of steps, improving the clarity and organization of agent tasks. Additionally, tests have been added to validate the new planning functionality and ensure proper integration with existing workflows.

title: "Private Package Registries"
description: "Install private Python packages from authenticated PyPI registries in CrewAI AMP"
icon: "lock"
mode: "wide"
---
<Note>
This guide covers how to configure your CrewAI project to install Python packages
from private PyPI registries (Azure DevOps Artifacts, GitHub Packages, GitLab, AWS CodeArtifact, etc.)
when deploying to CrewAI AMP.
</Note>
## When You Need This
If your project depends on internal or proprietary Python packages hosted on a private registry
rather than the public PyPI, you'll need to:
1. Tell UV **where** to find the package (an index URL)
2. Tell UV **which** packages come from that index (a source mapping)
3. Provide **credentials** so UV can authenticate during install
CrewAI AMP uses [UV](https://docs.astral.sh/uv/) for dependency resolution and installation.
UV supports authenticated private registries through `pyproject.toml` configuration combined
with environment variables for credentials.
## Step 1: Configure pyproject.toml
Three pieces work together in your `pyproject.toml`:
### 1a. Declare the dependency
Add the private package to your `[project.dependencies]` like any other dependency:
```toml
[project]
dependencies = [
"crewai[tools]>=0.100.1,<1.0.0",
"my-private-package>=1.2.0",
]
```
### 1b. Define the index
Register your private registry as a named index under `[[tool.uv.index]]`:
```toml
[[tool.uv.index]]
name = "my-private-registry"
url = "https://pkgs.dev.azure.com/my-org/_packaging/my-feed/pypi/simple/"
explicit = true
```
<Info>
The `name` field is important — UV uses it to construct the environment variable names
for authentication (see [Step 2](#step-2-set-authentication-credentials) below).
Setting `explicit = true` means UV won't search this index for every package — only the
ones you explicitly map to it in `[tool.uv.sources]`. This avoids unnecessary queries
against your private registry and protects against dependency confusion attacks.
</Info>
### 1c. Map the package to the index
Tell UV which packages should be resolved from your private index using `[tool.uv.sources]`:
```toml
[tool.uv.sources]
my-private-package = { index = "my-private-registry" }
```
### Complete example
```toml
[project]
name = "my-crew-project"
version = "0.1.0"
requires-python = ">=3.10,<=3.13"
dependencies = [
"crewai[tools]>=0.100.1,<1.0.0",
"my-private-package>=1.2.0",
]
[tool.crewai]
type = "crew"
[[tool.uv.index]]
name = "my-private-registry"
url = "https://pkgs.dev.azure.com/my-org/_packaging/my-feed/pypi/simple/"
explicit = true
[tool.uv.sources]
my-private-package = { index = "my-private-registry" }
```
After updating `pyproject.toml`, regenerate your lock file:
```bash
uv lock
```
<Warning>
Always commit the updated `uv.lock` along with your `pyproject.toml` changes.
The lock file is required for deployment — see [Prepare for Deployment](/en/enterprise/guides/prepare-for-deployment).
</Warning>
## Step 2: Set Authentication Credentials
UV authenticates against private indexes using environment variables that follow a naming convention
based on the index name you defined in `pyproject.toml`:
```
UV_INDEX_{UPPER_NAME}_USERNAME
UV_INDEX_{UPPER_NAME}_PASSWORD
```
Where `{UPPER_NAME}` is your index name converted to **uppercase** with **hyphens replaced by underscores**.
For example, an index named `my-private-registry` uses:
| Variable | Value |
|----------|-------|
| `UV_INDEX_MY_PRIVATE_REGISTRY_USERNAME` | Your registry username or token name |
| `UV_INDEX_MY_PRIVATE_REGISTRY_PASSWORD` | Your registry password or token/PAT |
<Warning>
These environment variables **must** be added via the CrewAI AMP **Environment Variables** settings —
either globally or at the deployment level. They cannot be set in `.env` files or hardcoded in your project.
See [Setting Environment Variables in AMP](#setting-environment-variables-in-amp) below.
</Warning>
## Registry Provider Reference
The table below shows the index URL format and credential values for common registry providers.
Replace placeholder values with your actual organization and feed details.
| Provider | Index URL | Username | Password |
|----------|-----------|----------|----------|
| **Azure DevOps Artifacts** | `https://pkgs.dev.azure.com/{org}/_packaging/{feed}/pypi/simple/` | Any non-empty string (e.g. `token`) | Personal Access Token (PAT) with Packaging Read scope |
| **GitHub Packages** | `https://pypi.pkg.github.com/{owner}/simple/` | GitHub username | Personal Access Token (classic) with `read:packages` scope |
| **GitLab Package Registry** | `https://gitlab.com/api/v4/projects/{project_id}/packages/pypi/simple/` | `__token__` | Project or Personal Access Token with `read_api` scope |
| **AWS CodeArtifact** | Use the URL from `aws codeartifact get-repository-endpoint` | `aws` | Token from `aws codeartifact get-authorization-token` |
| **Google Artifact Registry** | `https://{region}-python.pkg.dev/{project}/{repo}/simple/` | `_json_key_base64` | Base64-encoded service account key |
| **JFrog Artifactory** | `https://{instance}.jfrog.io/artifactory/api/pypi/{repo}/simple/` | Username or email | API key or identity token |
| **Self-hosted (devpi, Nexus, etc.)** | Your registry's simple API URL | Registry username | Registry password |
<Tip>
For **AWS CodeArtifact**, the authorization token expires periodically.
You'll need to refresh the `UV_INDEX_*_PASSWORD` value when it expires.
Consider automating this in your CI/CD pipeline.
</Tip>
## Setting Environment Variables in AMP
Private registry credentials must be configured as environment variables in CrewAI AMP.
You have two options:
<Tabs>
<Tab title="Web Interface">
1. Log in to [CrewAI AMP](https://app.crewai.com)
2. Navigate to your automation
3. Open the **Environment Variables** tab
4. Add each variable (`UV_INDEX_*_USERNAME` and `UV_INDEX_*_PASSWORD`) with its value
See the [Deploy to AMP — Set Environment Variables](/en/enterprise/guides/deploy-to-amp#set-environment-variables) step for details.
</Tab>
<Tab title="CLI Deployment">
Add the variables to your local `.env` file before running `crewai deploy create`.
The CLI will securely transfer them to the platform:
```bash
# .env
OPENAI_API_KEY=sk-...
UV_INDEX_MY_PRIVATE_REGISTRY_USERNAME=token
UV_INDEX_MY_PRIVATE_REGISTRY_PASSWORD=your-pat-here
```
```bash
crewai deploy create
```
</Tab>
</Tabs>
<Warning>
**Never** commit credentials to your repository. Use AMP environment variables for all secrets.
The `.env` file should be listed in `.gitignore`.
</Warning>
To update credentials on an existing deployment, see [Update Your Crew — Environment Variables](/en/enterprise/guides/update-crew).
## How It All Fits Together
When CrewAI AMP builds your automation, the resolution flow works like this:
<Steps>
<Step title="Build starts">
AMP pulls your repository and reads `pyproject.toml` and `uv.lock`.
</Step>
<Step title="UV resolves dependencies">
UV reads `[tool.uv.sources]` to determine which index each package should come from.
</Step>
<Step title="UV authenticates">
For each private index, UV looks up `UV_INDEX_{NAME}_USERNAME` and `UV_INDEX_{NAME}_PASSWORD`
from the environment variables you configured in AMP.
</Step>
<Step title="Packages install">
UV downloads and installs all packages — both public (from PyPI) and private (from your registry).
</Step>
<Step title="Automation runs">
Your crew or flow starts with all dependencies available.
</Step>
</Steps>
## Troubleshooting
### Authentication Errors During Build
**Symptom**: Build fails with `401 Unauthorized` or `403 Forbidden` when resolving a private package.
**Check**:
- The `UV_INDEX_*` environment variable names match your index name exactly (uppercased, hyphens → underscores)
- Credentials are set in AMP environment variables, not just in a local `.env`
- Your token/PAT has the required read permissions for the package feed
- The token hasn't expired (especially relevant for AWS CodeArtifact)
### Package Not Found
**Symptom**: `No matching distribution found for my-private-package`.
**Check**:
- The index URL in `pyproject.toml` ends with `/simple/`
- The `[tool.uv.sources]` entry maps the correct package name to the correct index name
- The package is actually published to your private registry
- Run `uv lock` locally with the same credentials to verify resolution works
### Lock File Conflicts
**Symptom**: `uv lock` fails or produces unexpected results after adding a private index.
**Solution**: Set the credentials locally and regenerate:
```bash
export UV_INDEX_MY_PRIVATE_REGISTRY_USERNAME=token
export UV_INDEX_MY_PRIVATE_REGISTRY_PASSWORD=your-pat
uv lock
```
Then commit the updated `uv.lock`.

title: "Moving from LangGraph to CrewAI: A Practical Guide for Engineers"
description: If you already have built with LangGraph, learn how to quickly port your projects to CrewAI
icon: switch
mode: "wide"
---
You've built agents with LangGraph. You've wrestled with `StateGraph`, wired up conditional edges, and debugged state dictionaries at 2 AM. It works — but somewhere along the way, you started wondering if there's a better path to production.
There is. **CrewAI Flows** gives you the same power — event-driven orchestration, conditional routing, shared state — with dramatically less boilerplate and a mental model that maps cleanly to how you actually think about multi-step AI workflows.
This article walks through the core concepts side by side, shows real code comparisons, and demonstrates why CrewAI Flows is the framework you'll want to reach for next.
---
## The Mental Model Shift
LangGraph asks you to think in **graphs**: nodes, edges, and state dictionaries. Every workflow is a directed graph where you explicitly wire transitions between computation steps. It's powerful, but the abstraction carries overhead — especially when your workflow is fundamentally sequential with a few decision points.
CrewAI Flows asks you to think in **events**: methods that start things, methods that listen for results, and methods that route execution. The topology of your workflow emerges from decorator annotations rather than explicit graph construction. This isn't just syntactic sugar — it changes how you design, read, and maintain your pipelines.
Here's the core mapping:
| LangGraph Concept | CrewAI Flows Equivalent |
| --- | --- |
| `StateGraph` class | `Flow` class |
| `add_node()` | Methods decorated with `@start`, `@listen` |
| `add_edge()` / `add_conditional_edges()` | `@listen()` / `@router()` decorators |
| `TypedDict` state | Pydantic `BaseModel` state |
| `START` / `END` constants | `@start()` decorator / natural method return |
| `graph.compile()` | `flow.kickoff()` |
| Checkpointer / persistence | Built-in memory (LanceDB-backed) |
Let's see what this looks like in practice.
---
## Demo 1: A Simple Sequential Pipeline
Imagine you're building a pipeline that takes a topic, researches it, writes a summary, and formats the output. Here's how each framework handles it.
### LangGraph Approach
```python
from typing import TypedDict
from langgraph.graph import StateGraph, START, END
class ResearchState(TypedDict):
topic: str
raw_research: str
summary: str
formatted_output: str
def research_topic(state: ResearchState) -> dict:
# Call an LLM or search API
result = llm.invoke(f"Research the topic: {state['topic']}")
return {"raw_research": result}
def write_summary(state: ResearchState) -> dict:
result = llm.invoke(
f"Summarize this research:\n{state['raw_research']}"
)
return {"summary": result}
def format_output(state: ResearchState) -> dict:
result = llm.invoke(
f"Format this summary as a polished article section:\n{state['summary']}"
)
return {"formatted_output": result}
# Build the graph
graph = StateGraph(ResearchState)
graph.add_node("research", research_topic)
graph.add_node("summarize", write_summary)
graph.add_node("format", format_output)
graph.add_edge(START, "research")
graph.add_edge("research", "summarize")
graph.add_edge("summarize", "format")
graph.add_edge("format", END)
# Compile and run
app = graph.compile()
result = app.invoke({"topic": "quantum computing advances in 2026"})
print(result["formatted_output"])
```
You define functions, register them as nodes, and manually wire every transition. For a simple sequence like this, there's a lot of ceremony.
### CrewAI Flows Approach
```python
from crewai import LLM, Agent, Crew, Process, Task
from crewai.flow.flow import Flow, listen, start
from pydantic import BaseModel
llm = LLM(model="openai/gpt-5.2")
class ResearchState(BaseModel):
topic: str = ""
raw_research: str = ""
summary: str = ""
formatted_output: str = ""
class ResearchFlow(Flow[ResearchState]):
@start()
def research_topic(self):
# Option 1: Direct LLM call
result = llm.call(f"Research the topic: {self.state.topic}")
self.state.raw_research = result
return result
@listen(research_topic)
def write_summary(self, research_output):
# Option 2: A single agent
summarizer = Agent(
role="Research Summarizer",
goal="Produce concise, accurate summaries of research content",
backstory="You are an expert at distilling complex research into clear, "
"digestible summaries.",
llm=llm,
verbose=True,
)
result = summarizer.kickoff(
f"Summarize this research:\n{self.state.raw_research}"
)
self.state.summary = str(result)
return self.state.summary
@listen(write_summary)
def format_output(self, summary_output):
# Option 3: a complete crew (with one or more agents)
formatter = Agent(
role="Content Formatter",
goal="Transform research summaries into polished, publication-ready article sections",
backstory="You are a skilled editor with expertise in structuring and "
"presenting technical content for a general audience.",
llm=llm,
verbose=True,
)
format_task = Task(
description=f"Format this summary as a polished article section:\n{self.state.summary}",
expected_output="A well-structured, polished article section ready for publication.",
agent=formatter,
)
crew = Crew(
agents=[formatter],
tasks=[format_task],
process=Process.sequential,
verbose=True,
)
result = crew.kickoff()
self.state.formatted_output = str(result)
return self.state.formatted_output
# Run the flow
flow = ResearchFlow()
flow.state.topic = "quantum computing advances in 2026"
result = flow.kickoff()
print(flow.state.formatted_output)
```
Notice what's different: no graph construction, no edge wiring, no compile step. The execution order is declared right where the logic lives. `@start()` marks the entry point, and `@listen(method_name)` chains steps together. The state is a proper Pydantic model with type safety, validation, and IDE auto-completion.
---
## Demo 2: Conditional Routing
This is where things get interesting. Say you're building a content pipeline that routes to different processing paths based on the type of content detected.
### LangGraph Approach
```python
from typing import TypedDict, Literal
from langgraph.graph import StateGraph, START, END
class ContentState(TypedDict):
input_text: str
content_type: str
result: str
def classify_content(state: ContentState) -> dict:
content_type = llm.invoke(
f"Classify this content as 'technical', 'creative', or 'business':\n{state['input_text']}"
)
return {"content_type": content_type.strip().lower()}
def process_technical(state: ContentState) -> dict:
result = llm.invoke(f"Process as technical doc:\n{state['input_text']}")
return {"result": result}
def process_creative(state: ContentState) -> dict:
result = llm.invoke(f"Process as creative writing:\n{state['input_text']}")
return {"result": result}
def process_business(state: ContentState) -> dict:
result = llm.invoke(f"Process as business content:\n{state['input_text']}")
return {"result": result}
# Routing function
def route_content(state: ContentState) -> Literal["technical", "creative", "business"]:
return state["content_type"]
# Build the graph
graph = StateGraph(ContentState)
graph.add_node("classify", classify_content)
graph.add_node("technical", process_technical)
graph.add_node("creative", process_creative)
graph.add_node("business", process_business)
graph.add_edge(START, "classify")
graph.add_conditional_edges(
"classify",
route_content,
{
"technical": "technical",
"creative": "creative",
"business": "business",
}
)
graph.add_edge("technical", END)
graph.add_edge("creative", END)
graph.add_edge("business", END)
app = graph.compile()
result = app.invoke({"input_text": "Explain how TCP handshakes work"})
```
You need a separate routing function, explicit conditional edge mapping, and termination edges for every branch. The routing logic is decoupled from the node that produces the routing decision.
### CrewAI Flows Approach
```python
from crewai import LLM, Agent
from crewai.flow.flow import Flow, listen, router, start
from pydantic import BaseModel
llm = LLM(model="openai/gpt-5.2")
class ContentState(BaseModel):
input_text: str = ""
content_type: str = ""
result: str = ""
class ContentFlow(Flow[ContentState]):
@start()
def classify_content(self):
self.state.content_type = (
llm.call(
f"Classify this content as 'technical', 'creative', or 'business':\n"
f"{self.state.input_text}"
)
.strip()
.lower()
)
return self.state.content_type
@router(classify_content)
def route_content(self, classification):
if classification == "technical":
return "process_technical"
elif classification == "creative":
return "process_creative"
else:
return "process_business"
@listen("process_technical")
def handle_technical(self):
agent = Agent(
role="Technical Writer",
goal="Produce clear, accurate technical documentation",
backstory="You are an expert technical writer who specializes in "
"explaining complex technical concepts precisely.",
llm=llm,
verbose=True,
)
self.state.result = str(
agent.kickoff(f"Process as technical doc:\n{self.state.input_text}")
)
@listen("process_creative")
def handle_creative(self):
agent = Agent(
role="Creative Writer",
goal="Craft engaging and imaginative creative content",
backstory="You are a talented creative writer with a flair for "
"compelling storytelling and vivid expression.",
llm=llm,
verbose=True,
)
self.state.result = str(
agent.kickoff(f"Process as creative writing:\n{self.state.input_text}")
)
@listen("process_business")
def handle_business(self):
agent = Agent(
role="Business Writer",
goal="Produce professional, results-oriented business content",
backstory="You are an experienced business writer who communicates "
"strategy and value clearly to professional audiences.",
llm=llm,
verbose=True,
)
self.state.result = str(
agent.kickoff(f"Process as business content:\n{self.state.input_text}")
)
flow = ContentFlow()
flow.state.input_text = "Explain how TCP handshakes work"
flow.kickoff()
print(flow.state.result)
```
The `@router()` decorator turns a method into a decision point. It returns a string that matches a listener — no mapping dictionaries, no separate routing functions. The branching logic reads like a Python `if` statement because it *is* one.
---
## Demo 3: Integrating AI Agent Crews into Flows
Here's where CrewAI's real power shines. Flows aren't just for chaining LLM calls — they orchestrate full **Crews** of autonomous agents. This is something LangGraph simply doesn't have a native equivalent for.
```python
from crewai import Agent, Task, Crew
from crewai.flow.flow import Flow, listen, start
from pydantic import BaseModel
class ArticleState(BaseModel):
topic: str = ""
research: str = ""
draft: str = ""
final_article: str = ""
class ArticleFlow(Flow[ArticleState]):
@start()
def run_research_crew(self):
"""A full Crew of agents handles research."""
researcher = Agent(
role="Senior Research Analyst",
goal=f"Produce comprehensive research on: {self.state.topic}",
backstory="You're a veteran analyst known for thorough, "
"well-sourced research reports.",
llm="gpt-4o"
)
research_task = Task(
description=f"Research '{self.state.topic}' thoroughly. "
"Cover key trends, data points, and expert opinions.",
expected_output="A detailed research brief with sources.",
agent=researcher
)
crew = Crew(agents=[researcher], tasks=[research_task])
result = crew.kickoff()
self.state.research = result.raw
return result.raw
@listen(run_research_crew)
def run_writing_crew(self, research_output):
"""A different Crew handles writing."""
writer = Agent(
role="Technical Writer",
goal="Write a compelling article based on provided research.",
backstory="You turn complex research into engaging, clear prose.",
llm="gpt-4o"
)
editor = Agent(
role="Senior Editor",
goal="Review and polish articles for publication quality.",
backstory="20 years of editorial experience at top tech publications.",
llm="gpt-4o"
)
write_task = Task(
description=f"Write an article based on this research:\n{self.state.research}",
expected_output="A well-structured draft article.",
agent=writer
)
edit_task = Task(
description="Review, fact-check, and polish the draft article.",
expected_output="A publication-ready article.",
agent=editor
)
crew = Crew(agents=[writer, editor], tasks=[write_task, edit_task])
result = crew.kickoff()
self.state.final_article = result.raw
return result.raw
# Run the full pipeline
flow = ArticleFlow()
flow.state.topic = "The Future of Edge AI"
flow.kickoff()
print(flow.state.final_article)
```
This is the key insight: **Flows provide the orchestration layer, and Crews provide the intelligence layer.** Each step in a Flow can spin up a full team of collaborating agents, each with their own roles, goals, and tools. You get structured, predictable control flow *and* autonomous agent collaboration — the best of both worlds.
In LangGraph, achieving something similar means manually implementing agent communication protocols, tool-calling loops, and delegation logic inside your node functions. It's possible, but it's plumbing you're building from scratch every time.
---
## Demo 4: Parallel Execution and Synchronization
Real-world pipelines often need to fan out work and join the results. CrewAI Flows handles this elegantly with `and_` and `or_` operators.
```python
from crewai import LLM
from crewai.flow.flow import Flow, and_, listen, start
from pydantic import BaseModel
llm = LLM(model="openai/gpt-5.2")
class AnalysisState(BaseModel):
topic: str = ""
market_data: str = ""
tech_analysis: str = ""
competitor_intel: str = ""
final_report: str = ""
class ParallelAnalysisFlow(Flow[AnalysisState]):
@start()
def start_method(self):
pass
@listen(start_method)
def gather_market_data(self):
# Your agentic or deterministic code
pass
@listen(start_method)
def run_tech_analysis(self):
# Your agentic or deterministic code
pass
@listen(start_method)
def gather_competitor_intel(self):
# Your agentic or deterministic code
pass
@listen(and_(gather_market_data, run_tech_analysis, gather_competitor_intel))
def synthesize_report(self):
# Your agentic or deterministic code
pass
flow = ParallelAnalysisFlow()
flow.state.topic = "AI-powered developer tools"
flow.kickoff()
```
Multiple `@start()` decorators fire in parallel. The `and_()` combinator on the `@listen` decorator ensures `synthesize_report` only executes after *all three* upstream methods complete. There's also `or_()` for when you want to proceed as soon as *any* upstream task finishes.
In LangGraph, you'd need to build a fan-out/fan-in pattern with parallel branches, a synchronization node, and careful state merging — all wired explicitly through edges.
---
## Why CrewAI Flows for Production
Beyond cleaner syntax, Flows deliver several production-critical advantages:
**Built-in state persistence.** Flow state is backed by LanceDB, meaning your workflows can survive crashes, be resumed, and accumulate knowledge across runs. LangGraph requires you to configure a separate checkpointer.
**Type-safe state management.** Pydantic models give you validation, serialization, and IDE support out of the box. LangGraph's `TypedDict` states don't validate at runtime.
**First-class agent orchestration.** Crews are a native primitive. You define agents with roles, goals, backstories, and tools — and they collaborate autonomously within the structured envelope of a Flow. No need to reinvent multi-agent coordination.
**Simpler mental model.** Decorators declare intent. `@start` means "begin here." `@listen(x)` means "run after x." `@router(x)` means "decide where to go after x." The code reads like the workflow it describes.
**CLI integration.** Run flows with `crewai run`. No separate compilation step, no graph serialization. Your Flow is a Python class, and it runs like one.
---
## Migration Cheat Sheet
If you're sitting on a LangGraph codebase and want to move to CrewAI Flows, here's a practical conversion guide:
1. **Map your state.** Convert your `TypedDict` to a Pydantic `BaseModel`. Add default values for all fields.
2. **Convert nodes to methods.** Each `add_node` function becomes a method on your `Flow` subclass. Replace `state["field"]` reads with `self.state.field`.
3. **Replace edges with decorators.** Your `add_edge(START, "first_node")` becomes `@start()` on the first method. Sequential `add_edge("a", "b")` becomes `@listen(a)` on method `b`.
4. **Replace conditional edges with `@router`.** Your routing function and `add_conditional_edges()` mapping become a single `@router()` method that returns a route string.
5. **Replace compile + invoke with kickoff.** Drop `graph.compile()`. Call `flow.kickoff()` instead.
6. **Consider where Crews fit.** Any node where you have complex multi-step agent logic is a candidate for extraction into a Crew. This is where you'll see the biggest quality improvement.
---
## Getting Started
Install CrewAI and scaffold a new Flow project:
```bash
pip install crewai
crewai create flow my_first_flow
cd my_first_flow
```
This generates a project structure with a ready-to-edit Flow class, configuration files, and a `pyproject.toml` with `type = "flow"` already set. Run it with:
```bash
crewai run
```
From there, add your agents, wire up your listeners, and ship it.
---
## Final Thoughts
LangGraph taught the ecosystem that AI workflows need structure. That was an important lesson. But CrewAI Flows takes that lesson and delivers it in a form that's faster to write, easier to read, and more powerful in production — especially when your workflows involve multiple collaborating agents.
If you're building anything beyond a single-agent chain, give Flows a serious look. The decorator-driven model, native Crew integration, and built-in state management mean you'll spend less time on plumbing and more time on the problems that matter.
Start with `crewai create flow`. You won't look back.

When the human says something like "needs more detail", the LLM collapses that to `"needs_revision"`, which triggers `review_content` again via `or_()` — creating a revision loop. The loop continues until the outcome is `"approved"` or `"rejected"`.

The LLM uses structured outputs (function calling) when available to guarantee the response is one of your specified outcomes. This makes routing reliable and predictable.

<Warning>
A `@start()` method only runs once at the beginning of the flow. If you need a revision loop, separate the start method from the review method and use `@listen(or_("trigger", "revision_outcome"))` on the review method to enable the self-loop.

</CodeGroup>
The key pattern is `@listen(or_("generate_draft", "needs_revision"))` — the review method listens to both the initial trigger and its own revision outcome, creating a self-loop that repeats until the human approves or rejects.
## Combining with Other Decorators
The `@human_feedback` decorator works with other flow decorators. Place it as the innermost decorator (closest to the function):
The `@human_feedback` decorator works with `@start()`, `@listen()`, and `or_()`. Both decorator orderings work — the framework propagates attributes in both directions — but the recommended patterns are:
```python Code
# Correct: @human_feedback is innermost (closest to the function)
# One-shot review at the start of a flow (no self-loop)
@start()
@human_feedback(message="Review this:")
@human_feedback(message="Review this:", emit=["approved", "rejected"], llm="gpt-4o-mini")
def my_start_method(self):
return "content"
# Linear review on a listener (no self-loop)
@listen(other_method)
@human_feedback(message="Review this too:")
@human_feedback(message="Review this too:", emit=["good", "bad"], llm="gpt-4o-mini")
def my_listener(self, data):
return f"processed: {data}"
# Self-loop: review that can loop back for revisions
@human_feedback(message="Approve or revise?", emit=["approved", "revise"], llm="gpt-4o-mini")
@listen(or_("upstream_method", "revise"))
def review_with_loop(self):
return "content for review"
```
<Tip>
Place `@human_feedback` as the innermost decorator (last/closest to the function) so it wraps the method directly and can capture the return value before passing to the flow system.
</Tip>
### Self-loop pattern
To create a revision loop, the review method must listen to **both** an upstream trigger and its own revision outcome using `or_()`:
```python Code
@start()
def generate(self):
return "initial draft"
@human_feedback(
message="Approve or request changes?",
emit=["revise", "approved"],
llm="gpt-4o-mini",
default_outcome="approved",
)
@listen(or_("generate", "revise"))
def review(self):
return "content"
@listen("approved")
def publish(self):
return "published"
```
When the outcome is `"revise"`, the flow routes back to `review` (because it listens to `"revise"` via `or_()`). When the outcome is `"approved"`, the flow continues to `publish`. This works because the flow engine exempts routers from the "fire once" rule, allowing them to re-execute on each loop iteration.
### Chained routers
A listener triggered by one router's outcome can itself be a router:
```python Code
@start()
def generate(self):
return "draft content"
@human_feedback(message="First review:", emit=["approved", "rejected"], llm="gpt-4o-mini")
@listen("generate")
def first_review(self):
return "draft content"
@human_feedback(message="Final review:", emit=["publish", "hold"], llm="gpt-4o-mini")
@listen("approved")
def final_review(self, prev):
return "final content"
@listen("publish")
def on_publish(self, prev):
return "published"
@listen("hold")
def on_hold(self, prev):
return "held for later"
```
### Limitations
- **`@start()` methods run once**: A `@start()` method cannot self-loop. If you need a revision cycle, use a separate `@start()` method as the entry point and put the `@human_feedback` on a `@listen()` method.
- **No `@start()` + `@listen()` on the same method**: This is a Flow framework constraint. A method is either a start point or a listener, not both.

## Connect CrewAI to LLMs
CrewAI uses LiteLLM to connect to a wide variety of Language Models (LLMs). This integration provides extensive versatility, allowing you to use models from numerous providers with a simple, unified interface.
CrewAI connects to LLMs through native SDK integrations for the most popular providers (OpenAI, Anthropic, Google Gemini, Azure, and AWS Bedrock), and uses LiteLLM as a flexible fallback for all other providers.
<Note>
By default, CrewAI uses the `gpt-4o-mini` model. This is determined by the `OPENAI_MODEL_NAME` environment variable, which defaults to "gpt-4o-mini" if not set.

For a complete and up-to-date list of supported providers, please refer to the [LiteLLM Providers documentation](https://docs.litellm.ai/docs/providers).

## Example
The following example demonstrates how to initialize the tool and execute a github action:
1. Initialize Composio toolset
1. Initialize Composio with CrewAI Provider
```python Code
from composio_crewai import ComposioToolSet, App, Action
from composio_crewai import ComposioProvider
from composio import Composio
from crewai import Agent, Task, Crew
toolset = ComposioToolSet()
composio = Composio(provider=ComposioProvider())
```
2. Connect your GitHub account
2. Create a new Composio Session and retrieve the tools
<CodeGroup>
```shell CLI
composio add github
```
```python Code
request = toolset.initiate_connection(app=App.GITHUB)
print(f"Open this URL to authenticate: {request.redirectUrl}")
```python
session = composio.create(
user_id="your-user-id",
toolkits=["gmail", "github"] # optional, default is all toolkits
)
tools = session.tools()
```
Read more about sessions and user management [here](https://docs.composio.dev/docs/configuring-sessions)
</CodeGroup>
3. Get Tools
3. Authenticating users manually
- Retrieving all the tools from an app (not recommended for production):
Composio automatically authenticates the users during the agent chat session. However, you can also authenticate the user manually by calling the `authorize` method.
```python Code
tools = toolset.get_tools(apps=[App.GITHUB])
connection_request = session.authorize("github")
print(f"Open this URL to authenticate: {connection_request.redirect_url}")
```
- Filtering tools based on tags:
```python Code
tag = "users"
filtered_action_enums = toolset.find_actions_by_tags(
App.GITHUB,
tags=[tag],
)
tools = toolset.get_tools(actions=filtered_action_enums)
```
- Filtering tools based on use case:
```python Code
use_case = "Star a repository on GitHub"
filtered_action_enums = toolset.find_actions_by_use_case(
App.GITHUB, use_case=use_case, advanced=False
)
tools = toolset.get_tools(actions=filtered_action_enums)
```
<Tip>Set `advanced` to True to get actions for complex use cases</Tip>
- Using specific tools:
In this demo, we will use the `GITHUB_STAR_A_REPOSITORY_FOR_THE_AUTHENTICATED_USER` action from the GitHub app.
```python Code
tools = toolset.get_tools(

title: "프라이빗 패키지 레지스트리"
description: "CrewAI AMP에서 인증된 PyPI 레지스트리의 프라이빗 Python 패키지 설치하기"
icon: "lock"
mode: "wide"
---
<Note>
이 가이드는 CrewAI AMP에 배포할 때 프라이빗 PyPI 레지스트리(Azure DevOps Artifacts, GitHub Packages,
GitLab, AWS CodeArtifact 등)에서 Python 패키지를 설치하도록 CrewAI 프로젝트를 구성하는 방법을 다룹니다.
</Note>
## 이 가이드가 필요한 경우
프로젝트가 공개 PyPI가 아닌 프라이빗 레지스트리에 호스팅된 내부 또는 독점 Python 패키지에
의존하는 경우, 다음을 수행해야 합니다:
1. UV에 패키지를 **어디서** 찾을지 알려줍니다 (index URL)
2. UV에 **어떤** 패키지가 해당 index에서 오는지 알려줍니다 (source 매핑)
3. UV가 설치 중에 인증할 수 있도록 **자격 증명**을 제공합니다
CrewAI AMP는 의존성 해결 및 설치에 [UV](https://docs.astral.sh/uv/)를 사용합니다.
UV는 `pyproject.toml` 구성과 자격 증명용 환경 변수를 결합하여 인증된 프라이빗 레지스트리를 지원합니다.
## 1단계: pyproject.toml 구성
`pyproject.toml`에서 세 가지 요소가 함께 작동합니다:
### 1a. 의존성 선언
프라이빗 패키지를 다른 의존성과 마찬가지로 `[project.dependencies]`에 추가합니다:
```toml
[project]
dependencies = [
"crewai[tools]>=0.100.1,<1.0.0",
"my-private-package>=1.2.0",
]
```
### 1b. index 정의
프라이빗 레지스트리를 `[[tool.uv.index]]` 아래에 명명된 index로 등록합니다:
```toml
[[tool.uv.index]]
name = "my-private-registry"
url = "https://pkgs.dev.azure.com/my-org/_packaging/my-feed/pypi/simple/"
explicit = true
```
<Info>
`name` 필드는 중요합니다 — UV는 이를 사용하여 인증을 위한 환경 변수 이름을
구성합니다 (아래 [2단계](#2단계-인증-자격-증명-설정)를 참조하세요).
`explicit = true`를 설정하면 UV가 모든 패키지에 대해 이 index를 검색하지 않습니다 —
`[tool.uv.sources]`에서 명시적으로 매핑한 패키지만 검색합니다. 이렇게 하면 프라이빗
레지스트리에 대한 불필요한 쿼리를 방지하고 의존성 혼동 공격을 차단할 수 있습니다.
</Info>
### 1c. 패키지를 index에 매핑
`[tool.uv.sources]`를 사용하여 프라이빗 index에서 해결해야 할 패키지를 UV에 알려줍니다:
```toml
[tool.uv.sources]
my-private-package = { index = "my-private-registry" }
```
### 전체 예시
```toml
[project]
name = "my-crew-project"
version = "0.1.0"
requires-python = ">=3.10,<=3.13"
dependencies = [
"crewai[tools]>=0.100.1,<1.0.0",
"my-private-package>=1.2.0",
]
[tool.crewai]
type = "crew"
[[tool.uv.index]]
name = "my-private-registry"
url = "https://pkgs.dev.azure.com/my-org/_packaging/my-feed/pypi/simple/"
explicit = true
[tool.uv.sources]
my-private-package = { index = "my-private-registry" }
```
`pyproject.toml`을 업데이트한 후 lock 파일을 다시 생성합니다:
```bash
uv lock
```
<Warning>
업데이트된 `uv.lock`을 항상 `pyproject.toml` 변경 사항과 함께 커밋하세요.
lock 파일은 배포에 필수입니다 — [배포 준비하기](/ko/enterprise/guides/prepare-for-deployment)를 참조하세요.
</Warning>
## 2단계: 인증 자격 증명 설정
UV는 `pyproject.toml`에서 정의한 index 이름을 기반으로 한 명명 규칙을 따르는
환경 변수를 사용하여 프라이빗 index에 인증합니다:
```
UV_INDEX_{UPPER_NAME}_USERNAME
UV_INDEX_{UPPER_NAME}_PASSWORD
```
여기서 `{UPPER_NAME}`은 index 이름을 **대문자**로 변환하고 **하이픈을 언더스코어로 대체**한 것입니다.
예를 들어, `my-private-registry`라는 이름의 index는 다음을 사용합니다:
| 변수 | 값 |
|------|-----|
| `UV_INDEX_MY_PRIVATE_REGISTRY_USERNAME` | 레지스트리 사용자 이름 또는 토큰 이름 |
| `UV_INDEX_MY_PRIVATE_REGISTRY_PASSWORD` | 레지스트리 비밀번호 또는 토큰/PAT |
<Warning>
이 환경 변수는 CrewAI AMP **환경 변수** 설정을 통해 **반드시** 추가해야 합니다 —
전역적으로 또는 배포 수준에서. `.env` 파일에 설정하거나 프로젝트에 하드코딩할 수 없습니다.
아래 [AMP에서 환경 변수 설정](#amp에서-환경-변수-설정)을 참조하세요.
</Warning>
## 레지스트리 제공업체 참조
아래 표는 일반적인 레지스트리 제공업체의 index URL 형식과 자격 증명 값을 보여줍니다.
자리 표시자 값을 실제 조직 및 피드 세부 정보로 대체하세요.
| 제공업체 | Index URL | 사용자 이름 | 비밀번호 |
|---------|-----------|-----------|---------|
| **Azure DevOps Artifacts** | `https://pkgs.dev.azure.com/{org}/_packaging/{feed}/pypi/simple/` | 비어 있지 않은 임의의 문자열 (예: `token`) | Packaging Read 범위의 Personal Access Token (PAT) |
| **GitHub Packages** | `https://pypi.pkg.github.com/{owner}/simple/` | GitHub 사용자 이름 | `read:packages` 범위의 Personal Access Token (classic) |
| **GitLab Package Registry** | `https://gitlab.com/api/v4/projects/{project_id}/packages/pypi/simple/` | `__token__` | `read_api` 범위의 Project 또는 Personal Access Token |
| **AWS CodeArtifact** | `aws codeartifact get-repository-endpoint`의 URL 사용 | `aws` | `aws codeartifact get-authorization-token`의 토큰 |
| **Google Artifact Registry** | `https://{region}-python.pkg.dev/{project}/{repo}/simple/` | `_json_key_base64` | Base64로 인코딩된 서비스 계정 키 |
| **JFrog Artifactory** | `https://{instance}.jfrog.io/artifactory/api/pypi/{repo}/simple/` | 사용자 이름 또는 이메일 | API 키 또는 ID 토큰 |
| **자체 호스팅 (devpi, Nexus 등)** | 레지스트리의 simple API URL | 레지스트리 사용자 이름 | 레지스트리 비밀번호 |
<Tip>
**AWS CodeArtifact**의 경우 인증 토큰이 주기적으로 만료됩니다.
만료되면 `UV_INDEX_*_PASSWORD` 값을 갱신해야 합니다.
CI/CD 파이프라인에서 이를 자동화하는 것을 고려하세요.
</Tip>
## AMP에서 환경 변수 설정
프라이빗 레지스트리 자격 증명은 CrewAI AMP에서 환경 변수로 구성해야 합니다.
두 가지 옵션이 있습니다:
<Tabs>
<Tab title="웹 인터페이스">
1. [CrewAI AMP](https://app.crewai.com)에 로그인합니다
2. 자동화로 이동합니다
3. **Environment Variables** 탭을 엽니다
4. 각 변수 (`UV_INDEX_*_USERNAME` 및 `UV_INDEX_*_PASSWORD`)에 값을 추가합니다
자세한 내용은 [AMP에 배포하기 — 환경 변수 설정하기](/ko/enterprise/guides/deploy-to-amp#환경-변수-설정하기) 단계를 참조하세요.
</Tab>
<Tab title="CLI 배포">
`crewai deploy create`를 실행하기 전에 로컬 `.env` 파일에 변수를 추가합니다.
CLI가 이를 안전하게 플랫폼으로 전송합니다:
```bash
# .env
OPENAI_API_KEY=sk-...
UV_INDEX_MY_PRIVATE_REGISTRY_USERNAME=token
UV_INDEX_MY_PRIVATE_REGISTRY_PASSWORD=your-pat-here
```
```bash
crewai deploy create
```
</Tab>
</Tabs>
<Warning>
자격 증명을 저장소에 **절대** 커밋하지 마세요. 모든 비밀 정보에는 AMP 환경 변수를 사용하세요.
`.env` 파일은 `.gitignore`에 포함되어야 합니다.
</Warning>
기존 배포의 자격 증명을 업데이트하려면 [Crew 업데이트하기 — 환경 변수](/ko/enterprise/guides/update-crew)를 참조하세요.
## 전체 동작 흐름
CrewAI AMP가 자동화를 빌드할 때, 해결 흐름은 다음과 같이 작동합니다:
<Steps>
<Step title="빌드 시작">
AMP가 저장소를 가져오고 `pyproject.toml`과 `uv.lock`을 읽습니다.
</Step>
<Step title="UV가 의존성 해결">
UV가 `[tool.uv.sources]`를 읽어 각 패키지가 어떤 index에서 와야 하는지 결정합니다.
</Step>
<Step title="UV가 인증">
각 프라이빗 index에 대해 UV가 AMP에서 구성한 환경 변수에서
`UV_INDEX_{NAME}_USERNAME`과 `UV_INDEX_{NAME}_PASSWORD`를 조회합니다.
</Step>
<Step title="패키지 설치">
UV가 공개(PyPI) 및 프라이빗(레지스트리) 패키지를 모두 다운로드하고 설치합니다.
</Step>
<Step title="자동화 실행">
모든 의존성이 사용 가능한 상태에서 crew 또는 flow가 시작됩니다.
</Step>
</Steps>
## 문제 해결
### 빌드 중 인증 오류
**증상**: 프라이빗 패키지를 해결할 때 `401 Unauthorized` 또는 `403 Forbidden`으로 빌드가 실패합니다.
**확인사항**:
- `UV_INDEX_*` 환경 변수 이름이 index 이름과 정확히 일치하는지 확인합니다 (대문자, 하이픈 -> 언더스코어)
- 자격 증명이 로컬 `.env`뿐만 아니라 AMP 환경 변수에 설정되어 있는지 확인합니다
- 토큰/PAT에 패키지 피드에 필요한 읽기 권한이 있는지 확인합니다
- 토큰이 만료되지 않았는지 확인합니다 (특히 AWS CodeArtifact의 경우)
### 패키지를 찾을 수 없음
**증상**: `No matching distribution found for my-private-package`.
**확인사항**:
- `pyproject.toml`의 index URL이 `/simple/`로 끝나는지 확인합니다
- `[tool.uv.sources]` 항목이 올바른 패키지 이름을 올바른 index 이름에 매핑하는지 확인합니다
- 패키지가 실제로 프라이빗 레지스트리에 게시되어 있는지 확인합니다
- 동일한 자격 증명으로 로컬에서 `uv lock`을 실행하여 해결이 작동하는지 확인합니다
### Lock 파일 충돌
**증상**: 프라이빗 index를 추가한 후 `uv lock`이 실패하거나 예상치 못한 결과를 생성합니다.
**해결책**: 로컬에서 자격 증명을 설정하고 다시 생성합니다:
```bash
export UV_INDEX_MY_PRIVATE_REGISTRY_USERNAME=token
export UV_INDEX_MY_PRIVATE_REGISTRY_PASSWORD=your-pat
uv lock
```
그런 다음 업데이트된 `uv.lock`을 커밋합니다.

title: "LangGraph에서 CrewAI로 옮기기: 엔지니어를 위한 실전 가이드"
description: LangGraph로 이미 구축했다면, 프로젝트를 CrewAI로 빠르게 옮기는 방법을 알아보세요
icon: switch
mode: "wide"
---
LangGraph로 에이전트를 구축해 왔습니다. `StateGraph`와 씨름하고, 조건부 에지를 연결하고, 새벽 2시에 상태 딕셔너리를 디버깅해 본 적도 있죠. 동작은 하지만 — 어느 순간부터 프로덕션으로 가는 더 나은 길이 없을까 고민하게 됩니다.
있습니다. **CrewAI Flows**는 이벤트 기반 오케스트레이션, 조건부 라우팅, 공유 상태라는 동일한 힘을 훨씬 적은 보일러플레이트와 실제로 다단계 AI 워크플로우를 생각하는 방식에 잘 맞는 정신적 모델로 제공합니다.
이 글은 핵심 개념을 나란히 비교하고 실제 코드 비교를 보여주며, 다음으로 손이 갈 프레임워크가 왜 CrewAI Flows인지 설명합니다.
---
## 정신적 모델의 전환
LangGraph는 **그래프**로 생각하라고 요구합니다: 노드, 에지, 그리고 상태 딕셔너리. 모든 워크플로우는 계산 단계 사이의 전이를 명시적으로 연결하는 방향 그래프입니다. 강력하지만, 특히 워크플로우가 몇 개의 결정 지점이 있는 순차적 흐름일 때 이 추상화는 오버헤드를 가져옵니다.
CrewAI Flows는 **이벤트**로 생각하라고 요구합니다: 시작하는 메서드, 결과를 듣는 메서드, 실행을 라우팅하는 메서드. 워크플로우의 토폴로지는 명시적 그래프 구성 대신 데코레이터 어노테이션에서 드러납니다. 이것은 단순한 문법 설탕이 아니라 — 파이프라인을 설계하고 읽고 유지하는 방식을 바꿉니다.
핵심 매핑은 다음과 같습니다:
| LangGraph 개념 | CrewAI Flows 대응 |
| --- | --- |
| `StateGraph` class | `Flow` class |
| `add_node()` | Methods decorated with `@start`, `@listen` |
| `add_edge()` / `add_conditional_edges()` | `@listen()` / `@router()` decorators |
| `TypedDict` state | Pydantic `BaseModel` state |
| `START` / `END` constants | `@start()` decorator / natural method return |
| `graph.compile()` | `flow.kickoff()` |
| Checkpointer / persistence | Built-in memory (LanceDB-backed) |
실제로 어떻게 보이는지 살펴보겠습니다.
---
## 데모 1: 간단한 순차 파이프라인
주제를 받아 조사하고, 요약을 작성한 뒤, 결과를 포맷팅하는 파이프라인을 만든다고 해봅시다. 각 프레임워크는 이렇게 처리합니다.
### LangGraph 방식
```python
from typing import TypedDict
from langgraph.graph import StateGraph, START, END
class ResearchState(TypedDict):
topic: str
raw_research: str
summary: str
formatted_output: str
def research_topic(state: ResearchState) -> dict:
# Call an LLM or search API
result = llm.invoke(f"Research the topic: {state['topic']}")
return {"raw_research": result}
def write_summary(state: ResearchState) -> dict:
result = llm.invoke(
f"Summarize this research:\n{state['raw_research']}"
)
return {"summary": result}
def format_output(state: ResearchState) -> dict:
result = llm.invoke(
f"Format this summary as a polished article section:\n{state['summary']}"
)
return {"formatted_output": result}
# Build the graph
graph = StateGraph(ResearchState)
graph.add_node("research", research_topic)
graph.add_node("summarize", write_summary)
graph.add_node("format", format_output)
graph.add_edge(START, "research")
graph.add_edge("research", "summarize")
graph.add_edge("summarize", "format")
graph.add_edge("format", END)
# Compile and run
app = graph.compile()
result = app.invoke({"topic": "quantum computing advances in 2026"})
print(result["formatted_output"])
```
함수를 정의하고 노드로 등록한 다음, 모든 전이를 수동으로 연결합니다. 이렇게 단순한 순서인데도 의례처럼 해야 할 작업이 많습니다.
### CrewAI Flows 방식
```python
from crewai import LLM, Agent, Crew, Process, Task
from crewai.flow.flow import Flow, listen, start
from pydantic import BaseModel
llm = LLM(model="openai/gpt-5.2")
class ResearchState(BaseModel):
topic: str = ""
raw_research: str = ""
summary: str = ""
formatted_output: str = ""
class ResearchFlow(Flow[ResearchState]):
@start()
def research_topic(self):
# Option 1: Direct LLM call
result = llm.call(f"Research the topic: {self.state.topic}")
self.state.raw_research = result
return result
@listen(research_topic)
def write_summary(self, research_output):
# Option 2: A single agent
summarizer = Agent(
role="Research Summarizer",
goal="Produce concise, accurate summaries of research content",
backstory="You are an expert at distilling complex research into clear, "
"digestible summaries.",
llm=llm,
verbose=True,
)
result = summarizer.kickoff(
f"Summarize this research:\n{self.state.raw_research}"
)
self.state.summary = str(result)
return self.state.summary
@listen(write_summary)
def format_output(self, summary_output):
# Option 3: a complete crew (with one or more agents)
formatter = Agent(
role="Content Formatter",
goal="Transform research summaries into polished, publication-ready article sections",
backstory="You are a skilled editor with expertise in structuring and "
"presenting technical content for a general audience.",
llm=llm,
verbose=True,
)
format_task = Task(
description=f"Format this summary as a polished article section:\n{self.state.summary}",
expected_output="A well-structured, polished article section ready for publication.",
agent=formatter,
)
crew = Crew(
agents=[formatter],
tasks=[format_task],
process=Process.sequential,
verbose=True,
)
result = crew.kickoff()
self.state.formatted_output = str(result)
return self.state.formatted_output
# Run the flow
flow = ResearchFlow()
flow.state.topic = "quantum computing advances in 2026"
result = flow.kickoff()
print(flow.state.formatted_output)
```
눈에 띄는 차이점이 있습니다: 그래프 구성 없음, 에지 연결 없음, 컴파일 단계 없음. 실행 순서는 로직이 있는 곳에서 바로 선언됩니다. `@start()`는 진입점을 표시하고, `@listen(method_name)`은 단계들을 연결합니다. 상태는 타입 안전성, 검증, IDE 자동 완성까지 제공하는 제대로 된 Pydantic 모델입니다.
---
## 데모 2: 조건부 라우팅
여기서 흥미로워집니다. 콘텐츠 유형에 따라 서로 다른 처리 경로로 라우팅하는 파이프라인을 만든다고 해봅시다.
### LangGraph 방식
```python
from typing import TypedDict, Literal
from langgraph.graph import StateGraph, START, END
class ContentState(TypedDict):
input_text: str
content_type: str
result: str
def classify_content(state: ContentState) -> dict:
content_type = llm.invoke(
f"Classify this content as 'technical', 'creative', or 'business':\n{state['input_text']}"
)
return {"content_type": content_type.strip().lower()}
def process_technical(state: ContentState) -> dict:
result = llm.invoke(f"Process as technical doc:\n{state['input_text']}")
return {"result": result}
def process_creative(state: ContentState) -> dict:
result = llm.invoke(f"Process as creative writing:\n{state['input_text']}")
return {"result": result}
def process_business(state: ContentState) -> dict:
result = llm.invoke(f"Process as business content:\n{state['input_text']}")
return {"result": result}
# Routing function
def route_content(state: ContentState) -> Literal["technical", "creative", "business"]:
return state["content_type"]
# Build the graph
graph = StateGraph(ContentState)
graph.add_node("classify", classify_content)
graph.add_node("technical", process_technical)
graph.add_node("creative", process_creative)
graph.add_node("business", process_business)
graph.add_edge(START, "classify")
graph.add_conditional_edges(
"classify",
route_content,
{
"technical": "technical",
"creative": "creative",
"business": "business",
}
)
graph.add_edge("technical", END)
graph.add_edge("creative", END)
graph.add_edge("business", END)
app = graph.compile()
result = app.invoke({"input_text": "Explain how TCP handshakes work"})
```
별도의 라우팅 함수, 명시적 조건부 에지 매핑, 그리고 모든 분기에 대한 종료 에지가 필요합니다. 라우팅 결정 로직이 그 결정을 만들어 내는 노드와 분리됩니다.
### CrewAI Flows 방식
```python
from crewai import LLM, Agent
from crewai.flow.flow import Flow, listen, router, start
from pydantic import BaseModel
llm = LLM(model="openai/gpt-5.2")
class ContentState(BaseModel):
input_text: str = ""
content_type: str = ""
result: str = ""
class ContentFlow(Flow[ContentState]):
@start()
def classify_content(self):
self.state.content_type = (
llm.call(
f"Classify this content as 'technical', 'creative', or 'business':\n"
f"{self.state.input_text}"
)
.strip()
.lower()
)
return self.state.content_type
@router(classify_content)
def route_content(self, classification):
if classification == "technical":
return "process_technical"
elif classification == "creative":
return "process_creative"
else:
return "process_business"
@listen("process_technical")
def handle_technical(self):
agent = Agent(
role="Technical Writer",
goal="Produce clear, accurate technical documentation",
backstory="You are an expert technical writer who specializes in "
"explaining complex technical concepts precisely.",
llm=llm,
verbose=True,
)
self.state.result = str(
agent.kickoff(f"Process as technical doc:\n{self.state.input_text}")
)
@listen("process_creative")
def handle_creative(self):
agent = Agent(
role="Creative Writer",
goal="Craft engaging and imaginative creative content",
backstory="You are a talented creative writer with a flair for "
"compelling storytelling and vivid expression.",
llm=llm,
verbose=True,
)
self.state.result = str(
agent.kickoff(f"Process as creative writing:\n{self.state.input_text}")
)
@listen("process_business")
def handle_business(self):
agent = Agent(
role="Business Writer",
goal="Produce professional, results-oriented business content",
backstory="You are an experienced business writer who communicates "
"strategy and value clearly to professional audiences.",
llm=llm,
verbose=True,
)
self.state.result = str(
agent.kickoff(f"Process as business content:\n{self.state.input_text}")
)
flow = ContentFlow()
flow.state.input_text = "Explain how TCP handshakes work"
flow.kickoff()
print(flow.state.result)
```
`@router()` 데코레이터는 메서드를 결정 지점으로 만듭니다. 리스너와 매칭되는 문자열을 반환하므로, 매핑 딕셔너리도, 별도의 라우팅 함수도 필요 없습니다. 분기 로직이 Python `if` 문처럼 읽히는 이유는, 실제로 `if` 문이기 때문입니다.
---
## 데모 3: AI 에이전트 Crew를 Flow에 통합하기
여기서 CrewAI의 진짜 힘이 드러납니다. Flows는 LLM 호출을 연결하는 것에 그치지 않고 자율적인 에이전트 **Crew** 전체를 오케스트레이션합니다. 이는 LangGraph에 기본으로 대응되는 개념이 없습니다.
```python
from crewai import Agent, Task, Crew
from crewai.flow.flow import Flow, listen, start
from pydantic import BaseModel
class ArticleState(BaseModel):
topic: str = ""
research: str = ""
draft: str = ""
final_article: str = ""
class ArticleFlow(Flow[ArticleState]):
@start()
def run_research_crew(self):
"""A full Crew of agents handles research."""
researcher = Agent(
role="Senior Research Analyst",
goal=f"Produce comprehensive research on: {self.state.topic}",
backstory="You're a veteran analyst known for thorough, "
"well-sourced research reports.",
llm="gpt-4o"
)
research_task = Task(
description=f"Research '{self.state.topic}' thoroughly. "
"Cover key trends, data points, and expert opinions.",
expected_output="A detailed research brief with sources.",
agent=researcher
)
crew = Crew(agents=[researcher], tasks=[research_task])
result = crew.kickoff()
self.state.research = result.raw
return result.raw
@listen(run_research_crew)
def run_writing_crew(self, research_output):
"""A different Crew handles writing."""
writer = Agent(
role="Technical Writer",
goal="Write a compelling article based on provided research.",
backstory="You turn complex research into engaging, clear prose.",
llm="gpt-4o"
)
editor = Agent(
role="Senior Editor",
goal="Review and polish articles for publication quality.",
backstory="20 years of editorial experience at top tech publications.",
llm="gpt-4o"
)
write_task = Task(
description=f"Write an article based on this research:\n{self.state.research}",
expected_output="A well-structured draft article.",
agent=writer
)
edit_task = Task(
description="Review, fact-check, and polish the draft article.",
expected_output="A publication-ready article.",
agent=editor
)
crew = Crew(agents=[writer, editor], tasks=[write_task, edit_task])
result = crew.kickoff()
self.state.final_article = result.raw
return result.raw
# Run the full pipeline
flow = ArticleFlow()
flow.state.topic = "The Future of Edge AI"
flow.kickoff()
print(flow.state.final_article)
```
핵심 인사이트는 다음과 같습니다: **Flows는 오케스트레이션 레이어를, Crews는 지능 레이어를 제공합니다.** Flow의 각 단계는 각자의 역할, 목표, 도구를 가진 협업 에이전트 팀을 띄울 수 있습니다. 구조화되고 예측 가능한 제어 흐름 *그리고* 자율적 에이전트 협업 — 두 세계의 장점을 모두 얻습니다.
LangGraph에서 비슷한 것을 하려면 노드 함수 안에 에이전트 통신 프로토콜, 도구 호출 루프, 위임 로직을 직접 구현해야 합니다. 가능하긴 하지만, 매번 처음부터 배관을 만드는 셈입니다.
---
## 데모 4: 병렬 실행과 동기화
실제 파이프라인은 종종 작업을 병렬로 분기하고 결과를 합쳐야 합니다. CrewAI Flows는 `and_`와 `or_` 연산자로 이를 우아하게 처리합니다.
```python
from crewai import LLM
from crewai.flow.flow import Flow, and_, listen, start
from pydantic import BaseModel
llm = LLM(model="openai/gpt-5.2")
class AnalysisState(BaseModel):
topic: str = ""
market_data: str = ""
tech_analysis: str = ""
competitor_intel: str = ""
final_report: str = ""
class ParallelAnalysisFlow(Flow[AnalysisState]):
@start()
def start_method(self):
pass
@listen(start_method)
def gather_market_data(self):
# Your agentic or deterministic code
pass
@listen(start_method)
def run_tech_analysis(self):
# Your agentic or deterministic code
pass
@listen(start_method)
def gather_competitor_intel(self):
# Your agentic or deterministic code
pass
@listen(and_(gather_market_data, run_tech_analysis, gather_competitor_intel))
def synthesize_report(self):
# Your agentic or deterministic code
pass
flow = ParallelAnalysisFlow()
flow.state.topic = "AI-powered developer tools"
flow.kickoff()

여러 `@start()` 데코레이터는 병렬로 실행됩니다. `@listen` 데코레이터의 `and_()` 결합자는 `synthesize_report`가 *세 가지* 상위 메서드가 모두 완료된 뒤에만 실행되도록 보장합니다. *어떤* 상위 작업이든 끝나는 즉시 진행하고 싶다면 `or_()`도 사용할 수 있습니다.
LangGraph에서는 병렬 분기, 동기화 노드, 신중한 상태 병합이 포함된 fan-out/fan-in 패턴을 만들어야 하며 — 모든 것을 에지로 명시적으로 연결해야 합니다.

## 프로덕션에서 CrewAI Flows를 쓰는 이유
깔끔한 문법을 넘어, Flows는 여러 프로덕션 핵심 이점을 제공합니다:
**내장 상태 지속성.** Flow 상태는 LanceDB에 의해 백업되므로 워크플로우가 크래시에서 살아남고, 재개될 수 있으며, 실행 간에 지식을 축적할 수 있습니다. LangGraph는 별도의 체크포인터를 구성해야 합니다.
**타입 안전한 상태 관리.** Pydantic 모델은 즉시 검증, 직렬화, IDE 지원을 제공합니다. LangGraph의 `TypedDict` 상태는 런타임 검증을 하지 않습니다.
**일급 에이전트 오케스트레이션.** Crews는 기본 프리미티브입니다. 역할, 목표, 배경, 도구를 가진 에이전트를 정의하고, Flow의 구조적 틀 안에서 자율적으로 협업하게 합니다. 다중 에이전트 조율을 다시 만들 필요가 없습니다.
**더 단순한 정신적 모델.** 데코레이터는 의도를 선언합니다. `@start`는 "여기서 시작", `@listen(x)`는 "x 이후 실행", `@router(x)`는 "x 이후 어디로 갈지 결정"을 의미합니다. 코드는 자신이 설명하는 워크플로우처럼 읽힙니다.
**CLI 통합.** `crewai run`으로 Flows를 실행합니다. 별도의 컴파일 단계나 그래프 직렬화가 없습니다. Flow는 Python 클래스이며, 그대로 실행됩니다.
---
## 마이그레이션 치트 시트
LangGraph 코드베이스를 CrewAI Flows로 옮기고 싶다면, 다음의 실전 변환 가이드를 참고하세요:
1. **상태를 매핑하세요.** `TypedDict`를 Pydantic `BaseModel`로 변환하고 모든 필드에 기본값을 추가하세요.
2. **노드를 메서드로 변환하세요.** 각 `add_node` 함수는 `Flow` 서브클래스의 메서드가 됩니다. `state["field"]` 읽기는 `self.state.field`로 바꾸세요.
3. **에지를 데코레이터로 교체하세요.** `add_edge(START, "first_node")`는 첫 메서드의 `@start()`가 됩니다. 순차적인 `add_edge("a", "b")`는 `b` 메서드의 `@listen(a)`가 됩니다.
4. **조건부 에지는 `@router`로 교체하세요.** 라우팅 함수와 `add_conditional_edges()` 매핑은 하나의 `@router()` 메서드로 통합하고, 라우트 문자열을 반환하세요.
5. **compile + invoke를 kickoff으로 교체하세요.** `graph.compile()`를 제거하고 `flow.kickoff()`를 호출하세요.
6. **Crew가 들어갈 지점을 고려하세요.** 복잡한 다단계 에이전트 로직이 있는 노드는 Crew로 분리할 후보입니다. 이 부분에서 가장 큰 품질 향상을 체감할 수 있습니다.
---
## 시작하기
CrewAI를 설치하고 새 Flow 프로젝트를 스캐폴딩하세요:
```bash
pip install crewai
crewai create flow my_first_flow
cd my_first_flow
```
이렇게 하면 바로 편집 가능한 Flow 클래스, 설정 파일, 그리고 `type = "flow"`가 이미 설정된 `pyproject.toml`이 포함된 프로젝트 구조가 생성됩니다. 다음으로 실행하세요:
```bash
crewai run
```
그 다음부터는 에이전트를 추가하고 리스너를 연결한 뒤, 배포하면 됩니다.
---
## 마무리
LangGraph는 AI 워크플로우에 구조가 필요하다는 사실을 생태계에 일깨워 주었습니다. 중요한 교훈이었습니다. 하지만 CrewAI Flows는 그 교훈을 더 빠르게 쓰고, 더 쉽게 읽으며, 프로덕션에서 더 강력한 형태로 제공합니다 — 특히 워크플로우에 여러 에이전트의 협업이 포함될 때 그렇습니다.
단일 에이전트 체인을 넘는 무엇인가를 만들고 있다면, Flows를 진지하게 검토해 보세요. 데코레이터 기반 모델, Crews의 네이티브 통합, 내장 상태 관리를 통해 배관 작업에 쓰는 시간을 줄이고, 중요한 문제에 더 많은 시간을 쓸 수 있습니다.
`crewai create flow`로 시작하세요. 후회하지 않을 겁니다.

사용자가 "더 자세한 내용이 필요합니다"와 같이 말하면, LLM이 이를 `"needs_revision"`으로 매핑하고, `or_()`를 통해 `review_content`가 다시 트리거됩니다 — 수정 루프가 생성됩니다. outcome이 `"approved"` 또는 `"rejected"`가 될 때까지 루프가 계속됩니다.
<Tip>
LLM은 가능한 경우 구조화된 출력(function calling)을 사용하여 응답이 지정된 outcome 중 하나임을 보장합니다. 이로 인해 라우팅이 신뢰할 수 있고 예측 가능해집니다.

## 다른 데코레이터와 결합하기
`@human_feedback` 데코레이터는 다른 Flow 데코레이터와 함께 작동합니다. 가장 안쪽 데코레이터(함수에 가장 가까운)로 배치하세요:
`@human_feedback` 데코레이터는 `@start()`, `@listen()`, `or_()`와 함께 작동합니다. 데코레이터 순서는 두 가지 모두 동작합니다—프레임워크가 양방향으로 속성을 전파합니다—하지만 권장 패턴은 다음과 같습니다:
```python Code
# 올바름: @human_feedback이 가장 안쪽(함수에 가장 가까움)
# Flow 시작 시 일회성 검토 (self-loop 없음)
@start()
@human_feedback(message="이것을 검토해 주세요:")
@human_feedback(message="이것을 검토해 주세요:", emit=["approved", "rejected"], llm="gpt-4o-mini")
def my_start_method(self):
return "content"
# 리스너에서 선형 검토 (self-loop 없음)
@listen(other_method)
@human_feedback(message="이것도 검토해 주세요:")
@human_feedback(message="이것도 검토해 주세요:", emit=["good", "bad"], llm="gpt-4o-mini")
def my_listener(self, data):
return f"processed: {data}"
# Self-loop: 수정을 위해 반복할 수 있는 검토
@human_feedback(message="승인 또는 수정 요청?", emit=["approved", "revise"], llm="gpt-4o-mini")
@listen(or_("upstream_method", "revise"))
def review_with_loop(self):
return "content for review"
```
<Tip>
`@human_feedback`를 가장 안쪽 데코레이터(마지막/함수에 가장 가까움)로 배치하여 메서드를 직접 래핑하고 Flow 시스템에 전달하기 전에 반환 값을 캡처할 수 있도록 하세요.
</Tip>
### Self-loop 패턴
수정 루프를 만들려면 `or_()`를 사용하여 검토 메서드가 **상위 트리거**와 **자체 수정 outcome**을 모두 리스닝해야 합니다:
```python Code
@start()
def generate(self):
return "initial draft"
@human_feedback(
message="승인하시겠습니까, 아니면 변경을 요청하시겠습니까?",
emit=["revise", "approved"],
llm="gpt-4o-mini",
default_outcome="approved",
)
@listen(or_("generate", "revise"))
def review(self):
return "content"
@listen("approved")
def publish(self):
return "published"
```
outcome이 `"revise"`이면 flow가 `review`로 다시 라우팅됩니다 (`or_()`를 통해 `"revise"`를 리스닝하기 때문). outcome이 `"approved"`이면 flow가 `publish`로 계속됩니다. flow 엔진이 라우터를 "한 번만 실행" 규칙에서 제외하여 각 루프 반복마다 재실행할 수 있기 때문에 이 패턴이 동작합니다.
### 체인된 라우터
한 라우터의 outcome으로 트리거된 리스너가 그 자체로 라우터가 될 수 있습니다:
```python Code
@start()
@human_feedback(message="첫 번째 검토:", emit=["approved", "rejected"], llm="gpt-4o-mini")
def draft(self):
return "draft content"
@listen("approved")
@human_feedback(message="최종 검토:", emit=["publish", "revise"], llm="gpt-4o-mini")
def final_review(self, prev):
return "final content"
@listen("publish")
def on_publish(self, prev):
return "published"
```
### 제한 사항
- **`@start()` 메서드는 한 번만 실행**: `@start()` 메서드는 self-loop할 수 없습니다. 수정 주기가 필요하면 별도의 `@start()` 메서드를 진입점으로 사용하고 `@listen()` 메서드에 `@human_feedback`를 배치하세요.
- **동일 메서드에 `@start()` + `@listen()` 불가**: 이는 Flow 프레임워크 제약입니다. 메서드는 시작점이거나 리스너여야 하며, 둘 다일 수 없습니다.

title: "Registros de Pacotes Privados"
description: "Instale pacotes Python privados de registros PyPI autenticados no CrewAI AMP"
icon: "lock"
mode: "wide"
---
<Note>
Este guia aborda como configurar seu projeto CrewAI para instalar pacotes Python
de registros PyPI privados (Azure DevOps Artifacts, GitHub Packages, GitLab, AWS CodeArtifact, etc.)
ao implantar no CrewAI AMP.
</Note>
## Quando Você Precisa Disso
Se seu projeto depende de pacotes Python internos ou proprietários hospedados em um registro privado
em vez do PyPI público, você precisará:
1. Informar ao UV **onde** encontrar o pacote (uma URL de index)
2. Informar ao UV **quais** pacotes vêm desse index (um mapeamento de source)
3. Fornecer **credenciais** para que o UV possa autenticar durante a instalação
O CrewAI AMP usa [UV](https://docs.astral.sh/uv/) para resolução e instalação de dependências.
O UV suporta registros privados autenticados por meio da configuração do `pyproject.toml` combinada
com variáveis de ambiente para credenciais.
## Passo 1: Configurar o pyproject.toml
Três elementos trabalham juntos no seu `pyproject.toml`:
### 1a. Declarar a dependência
Adicione o pacote privado ao seu `[project.dependencies]` como qualquer outra dependência:
```toml
[project]
dependencies = [
"crewai[tools]>=0.100.1,<1.0.0",
"my-private-package>=1.2.0",
]
```
### 1b. Definir o index
Registre seu registro privado como um index nomeado em `[[tool.uv.index]]`:
```toml
[[tool.uv.index]]
name = "my-private-registry"
url = "https://pkgs.dev.azure.com/my-org/_packaging/my-feed/pypi/simple/"
explicit = true
```
<Info>
O campo `name` é importante — o UV o utiliza para construir os nomes das variáveis de ambiente
para autenticação (veja o [Passo 2](#passo-2-configurar-credenciais-de-autenticação) abaixo).
Definir `explicit = true` significa que o UV não consultará esse index para todos os pacotes — apenas
os que você mapear explicitamente em `[tool.uv.sources]`. Isso evita consultas desnecessárias
ao seu registro privado e protege contra ataques de confusão de dependências.
</Info>
### 1c. Mapear o pacote para o index
Informe ao UV quais pacotes devem ser resolvidos a partir do seu index privado usando `[tool.uv.sources]`:
```toml
[tool.uv.sources]
my-private-package = { index = "my-private-registry" }
```
### Exemplo completo
```toml
[project]
name = "my-crew-project"
version = "0.1.0"
requires-python = ">=3.10,<=3.13"
dependencies = [
"crewai[tools]>=0.100.1,<1.0.0",
"my-private-package>=1.2.0",
]
[tool.crewai]
type = "crew"
[[tool.uv.index]]
name = "my-private-registry"
url = "https://pkgs.dev.azure.com/my-org/_packaging/my-feed/pypi/simple/"
explicit = true
[tool.uv.sources]
my-private-package = { index = "my-private-registry" }
```
Após atualizar o `pyproject.toml`, regenere seu arquivo lock:
```bash
uv lock
```
<Warning>
Sempre faça commit do `uv.lock` atualizado junto com as alterações no `pyproject.toml`.
O arquivo lock é obrigatório para implantação — veja [Preparar para Implantação](/pt-BR/enterprise/guides/prepare-for-deployment).
</Warning>
## Passo 2: Configurar Credenciais de Autenticação
O UV autentica em indexes privados usando variáveis de ambiente que seguem uma convenção de nomenclatura
baseada no nome do index que você definiu no `pyproject.toml`:
```
UV_INDEX_{UPPER_NAME}_USERNAME
UV_INDEX_{UPPER_NAME}_PASSWORD
```
Onde `{UPPER_NAME}` é o nome do seu index convertido para **maiúsculas** com **hifens substituídos por underscores**.
Por exemplo, um index chamado `my-private-registry` usa:
| Variável | Valor |
|----------|-------|
| `UV_INDEX_MY_PRIVATE_REGISTRY_USERNAME` | Seu nome de usuário ou nome do token do registro |
| `UV_INDEX_MY_PRIVATE_REGISTRY_PASSWORD` | Sua senha ou token/PAT do registro |
<Warning>
Essas variáveis de ambiente **devem** ser adicionadas pelas configurações de **Variáveis de Ambiente** do CrewAI AMP —
globalmente ou no nível da implantação. Elas não podem ser definidas em arquivos `.env` ou codificadas no seu projeto.
Veja [Configurar Variáveis de Ambiente no AMP](#configurar-variáveis-de-ambiente-no-amp) abaixo.
</Warning>
## Referência de Provedores de Registro
A tabela abaixo mostra o formato da URL de index e os valores de credenciais para provedores de registro comuns.
Substitua os valores de exemplo pelos detalhes reais da sua organização e feed.
| Provedor | URL do Index | Usuário | Senha |
|----------|-------------|---------|-------|
| **Azure DevOps Artifacts** | `https://pkgs.dev.azure.com/{org}/_packaging/{feed}/pypi/simple/` | Qualquer string não vazia (ex: `token`) | Personal Access Token (PAT) com escopo Packaging Read |
| **GitHub Packages** | `https://pypi.pkg.github.com/{owner}/simple/` | Nome de usuário do GitHub | Personal Access Token (classic) com escopo `read:packages` |
| **GitLab Package Registry** | `https://gitlab.com/api/v4/projects/{project_id}/packages/pypi/simple/` | `__token__` | Project ou Personal Access Token com escopo `read_api` |
| **AWS CodeArtifact** | Use a URL de `aws codeartifact get-repository-endpoint` | `aws` | Token de `aws codeartifact get-authorization-token` |
| **Google Artifact Registry** | `https://{region}-python.pkg.dev/{project}/{repo}/simple/` | `_json_key_base64` | Chave de conta de serviço codificada em Base64 |
| **JFrog Artifactory** | `https://{instance}.jfrog.io/artifactory/api/pypi/{repo}/simple/` | Nome de usuário ou email | Chave API ou token de identidade |
| **Auto-hospedado (devpi, Nexus, etc.)** | URL da API simple do seu registro | Nome de usuário do registro | Senha do registro |
<Tip>
Para **AWS CodeArtifact**, o token de autorização expira periodicamente.
Você precisará atualizar o valor de `UV_INDEX_*_PASSWORD` quando ele expirar.
Considere automatizar isso no seu pipeline de CI/CD.
</Tip>
## Configurar Variáveis de Ambiente no AMP
As credenciais do registro privado devem ser configuradas como variáveis de ambiente no CrewAI AMP.
Você tem duas opções:
<Tabs>
<Tab title="Interface Web">
1. Faça login no [CrewAI AMP](https://app.crewai.com)
2. Navegue até sua automação
3. Abra a aba **Environment Variables**
4. Adicione cada variável (`UV_INDEX_*_USERNAME` e `UV_INDEX_*_PASSWORD`) com seu valor
Veja o passo [Deploy para AMP — Definir Variáveis de Ambiente](/pt-BR/enterprise/guides/deploy-to-amp#definir-as-variáveis-de-ambiente) para detalhes.
</Tab>
<Tab title="Implantação via CLI">
Adicione as variáveis ao seu arquivo `.env` local antes de executar `crewai deploy create`.
A CLI as transferirá com segurança para a plataforma:
```bash
# .env
OPENAI_API_KEY=sk-...
UV_INDEX_MY_PRIVATE_REGISTRY_USERNAME=token
UV_INDEX_MY_PRIVATE_REGISTRY_PASSWORD=your-pat-here
```
```bash
crewai deploy create
```
</Tab>
</Tabs>
<Warning>
**Nunca** faça commit de credenciais no seu repositório. Use variáveis de ambiente do AMP para todos os segredos.
O arquivo `.env` deve estar listado no `.gitignore`.
</Warning>
Para atualizar credenciais em uma implantação existente, veja [Atualizar Seu Crew — Variáveis de Ambiente](/pt-BR/enterprise/guides/update-crew).
## Como Tudo se Conecta
Quando o CrewAI AMP faz o build da sua automação, o fluxo de resolução funciona assim:
<Steps>
<Step title="Build inicia">
O AMP busca seu repositório e lê o `pyproject.toml` e o `uv.lock`.
</Step>
<Step title="UV resolve dependências">
O UV lê `[tool.uv.sources]` para determinar de qual index cada pacote deve vir.
</Step>
<Step title="UV autentica">
Para cada index privado, o UV busca `UV_INDEX_{NAME}_USERNAME` e `UV_INDEX_{NAME}_PASSWORD`
nas variáveis de ambiente que você configurou no AMP.
</Step>
<Step title="Pacotes são instalados">
O UV baixa e instala todos os pacotes — tanto públicos (do PyPI) quanto privados (do seu registro).
</Step>
<Step title="Automação executa">
Seu crew ou flow inicia com todas as dependências disponíveis.
</Step>
</Steps>
## Solução de Problemas
### Erros de Autenticação Durante o Build
**Sintoma**: Build falha com `401 Unauthorized` ou `403 Forbidden` ao resolver um pacote privado.
**Verifique**:
- Os nomes das variáveis de ambiente `UV_INDEX_*` correspondem exatamente ao nome do seu index (maiúsculas, hifens -> underscores)
- As credenciais estão definidas nas variáveis de ambiente do AMP, não apenas em um `.env` local
- Seu token/PAT tem as permissões de leitura necessárias para o feed de pacotes
- O token não expirou (especialmente relevante para AWS CodeArtifact)
### Pacote Não Encontrado
**Sintoma**: `No matching distribution found for my-private-package`.
**Verifique**:
- A URL do index no `pyproject.toml` termina com `/simple/`
- A entrada `[tool.uv.sources]` mapeia o nome correto do pacote para o nome correto do index
- O pacote está realmente publicado no seu registro privado
- Execute `uv lock` localmente com as mesmas credenciais para verificar se a resolução funciona
### Conflitos no Arquivo Lock
**Sintoma**: `uv lock` falha ou produz resultados inesperados após adicionar um index privado.
**Solução**: Defina as credenciais localmente e regenere:
```bash
export UV_INDEX_MY_PRIVATE_REGISTRY_USERNAME=token
export UV_INDEX_MY_PRIVATE_REGISTRY_PASSWORD=your-pat
uv lock
```
Em seguida, faça commit do `uv.lock` atualizado.

title: "Migrando do LangGraph para o CrewAI: um guia prático para engenheiros"
description: Se você já construiu com LangGraph, saiba como portar rapidamente seus projetos para o CrewAI
icon: switch
mode: "wide"
---
Você construiu agentes com LangGraph. Já lutou com o `StateGraph`, ligou arestas condicionais e depurou dicionários de estado às 2 da manhã. Funciona — mas, em algum momento, você começou a se perguntar se existe um caminho melhor para produção.
Existe. **CrewAI Flows** entrega o mesmo poder — orquestração orientada a eventos, roteamento condicional, estado compartilhado — com muito menos boilerplate e um modelo mental que se alinha a como você realmente pensa sobre fluxos de trabalho de IA em múltiplas etapas.
Este artigo apresenta os conceitos principais lado a lado, mostra comparações reais de código e demonstra por que o CrewAI Flows é o framework que você vai querer usar a seguir.
---
## A Mudança de Modelo Mental
LangGraph pede que você pense em **grafos**: nós, arestas e dicionários de estado. Todo workflow é um grafo direcionado em que você conecta explicitamente as transições entre as etapas de computação. É poderoso, mas a abstração traz overhead — especialmente quando o seu fluxo é fundamentalmente sequencial com alguns pontos de decisão.
CrewAI Flows pede que você pense em **eventos**: métodos que iniciam, métodos que escutam resultados e métodos que roteiam a execução. A topologia do workflow emerge de anotações com decorators, em vez de construção explícita do grafo. Isso não é apenas açúcar sintático — muda como você projeta, lê e mantém seus pipelines.
Veja o mapeamento principal:
| Conceito no LangGraph | Equivalente no CrewAI Flows |
| --- | --- |
| `StateGraph` class | `Flow` class |
| `add_node()` | Methods decorated with `@start`, `@listen` |
| `add_edge()` / `add_conditional_edges()` | `@listen()` / `@router()` decorators |
| `TypedDict` state | Pydantic `BaseModel` state |
| `START` / `END` constants | `@start()` decorator / natural method return |
| `graph.compile()` | `flow.kickoff()` |
| Checkpointer / persistence | Built-in memory (LanceDB-backed) |
Vamos ver como isso fica na prática.
---
## Demo 1: Um Pipeline Sequencial Simples
Imagine que você está construindo um pipeline que recebe um tema, pesquisa, escreve um resumo e formata a saída. Veja como cada framework lida com isso.
### Abordagem com LangGraph
```python
from typing import TypedDict
from langgraph.graph import StateGraph, START, END
class ResearchState(TypedDict):
topic: str
raw_research: str
summary: str
formatted_output: str
def research_topic(state: ResearchState) -> dict:
# Call an LLM or search API
result = llm.invoke(f"Research the topic: {state['topic']}")
return {"raw_research": result}
def write_summary(state: ResearchState) -> dict:
result = llm.invoke(
f"Summarize this research:\n{state['raw_research']}"
)
return {"summary": result}
def format_output(state: ResearchState) -> dict:
result = llm.invoke(
f"Format this summary as a polished article section:\n{state['summary']}"
)
return {"formatted_output": result}
# Build the graph
graph = StateGraph(ResearchState)
graph.add_node("research", research_topic)
graph.add_node("summarize", write_summary)
graph.add_node("format", format_output)
graph.add_edge(START, "research")
graph.add_edge("research", "summarize")
graph.add_edge("summarize", "format")
graph.add_edge("format", END)
# Compile and run
app = graph.compile()
result = app.invoke({"topic": "quantum computing advances in 2026"})
print(result["formatted_output"])
```
Você define funções, registra-as como nós e conecta manualmente cada transição. Para uma sequência simples como essa, há muita cerimônia.
### Abordagem com CrewAI Flows
```python
from crewai import LLM, Agent, Crew, Process, Task
from crewai.flow.flow import Flow, listen, start
from pydantic import BaseModel
llm = LLM(model="openai/gpt-5.2")
class ResearchState(BaseModel):
topic: str = ""
raw_research: str = ""
summary: str = ""
formatted_output: str = ""
class ResearchFlow(Flow[ResearchState]):
@start()
def research_topic(self):
# Option 1: Direct LLM call
result = llm.call(f"Research the topic: {self.state.topic}")
self.state.raw_research = result
return result
@listen(research_topic)
def write_summary(self, research_output):
# Option 2: A single agent
summarizer = Agent(
role="Research Summarizer",
goal="Produce concise, accurate summaries of research content",
backstory="You are an expert at distilling complex research into clear, "
"digestible summaries.",
llm=llm,
verbose=True,
)
result = summarizer.kickoff(
f"Summarize this research:\n{self.state.raw_research}"
)
self.state.summary = str(result)
return self.state.summary
@listen(write_summary)
def format_output(self, summary_output):
# Option 3: a complete crew (with one or more agents)
formatter = Agent(
role="Content Formatter",
goal="Transform research summaries into polished, publication-ready article sections",
backstory="You are a skilled editor with expertise in structuring and "
"presenting technical content for a general audience.",
llm=llm,
verbose=True,
)
format_task = Task(
description=f"Format this summary as a polished article section:\n{self.state.summary}",
expected_output="A well-structured, polished article section ready for publication.",
agent=formatter,
)
crew = Crew(
agents=[formatter],
tasks=[format_task],
process=Process.sequential,
verbose=True,
)
result = crew.kickoff()
self.state.formatted_output = str(result)
return self.state.formatted_output
# Run the flow
flow = ResearchFlow()
flow.state.topic = "quantum computing advances in 2026"
result = flow.kickoff()
print(flow.state.formatted_output)
```
Repare a diferença: nada de construção de grafo, de ligação de arestas, nem de etapa de compilação. A ordem de execução é declarada exatamente onde a lógica vive. `@start()` marca o ponto de entrada, e `@listen(method_name)` encadeia as etapas. O estado é um modelo Pydantic de verdade, com segurança de tipos, validação e auto-complete na IDE.
---
## Demo 2: Roteamento Condicional
Aqui é que fica interessante. Digamos que você está construindo um pipeline de conteúdo que roteia para diferentes caminhos de processamento com base no tipo de conteúdo detectado.
### Abordagem com LangGraph
```python
from typing import TypedDict, Literal
from langgraph.graph import StateGraph, START, END

### Abordagem com CrewAI Flows
```python
from crewai import LLM, Agent
from crewai.flow.flow import Flow, listen, router, start
from pydantic import BaseModel
llm = LLM(model="openai/gpt-5.2")
class ContentState(BaseModel):
input_text: str = ""
content_type: str = ""
result: str = ""
class ContentFlow(Flow[ContentState]):
@start()
def classify_content(self):
self.state.content_type = (
llm.call(
f"Classify this content as 'technical', 'creative', or 'business':\n"
f"{self.state.input_text}"
)
.strip()
.lower()
)
return self.state.content_type
@router(classify_content)
def route_content(self, classification):
if classification == "technical":
return "process_technical"
elif classification == "creative":
return "process_creative"
else:
return "process_business"
@listen("process_technical")
def handle_technical(self):
agent = Agent(
role="Technical Writer",
goal="Produce clear, accurate technical documentation",
backstory="You are an expert technical writer who specializes in "
"explaining complex technical concepts precisely.",
llm=llm,
verbose=True,
)
self.state.result = str(
agent.kickoff(f"Process as technical doc:\n{self.state.input_text}")
)
@listen("process_creative")
def handle_creative(self):
agent = Agent(
role="Creative Writer",
goal="Craft engaging and imaginative creative content",
backstory="You are a talented creative writer with a flair for "
"compelling storytelling and vivid expression.",
llm=llm,
verbose=True,
)
self.state.result = str(
agent.kickoff(f"Process as creative writing:\n{self.state.input_text}")
)
@listen("process_business")
def handle_business(self):
agent = Agent(
role="Business Writer",
goal="Produce professional, results-oriented business content",
backstory="You are an experienced business writer who communicates "
"strategy and value clearly to professional audiences.",
llm=llm,
verbose=True,
)
self.state.result = str(
agent.kickoff(f"Process as business content:\n{self.state.input_text}")
)
flow = ContentFlow()
flow.state.input_text = "Explain how TCP handshakes work"
flow.kickoff()
print(flow.state.result)
```
O decorator `@router()` transforma um método em um ponto de decisão. Ele retorna uma string que corresponde a um listener — sem dicionários de mapeamento, sem funções de roteamento separadas. A lógica de ramificação parece um `if` em Python porque *é* um.

## Demo 3: Integrando Crews de Agentes de IA em Flows
É aqui que o verdadeiro poder do CrewAI aparece. Flows não servem apenas para encadear chamadas de LLM — elas orquestram **Crews** completas de agentes autônomos. Isso é algo para o qual o LangGraph simplesmente não tem um equivalente nativo.
```python
from crewai import Agent, Task, Crew
from crewai.flow.flow import Flow, listen, start
from pydantic import BaseModel
class ArticleState(BaseModel):
topic: str = ""
research: str = ""
draft: str = ""
final_article: str = ""
class ArticleFlow(Flow[ArticleState]):
@start()
def run_research_crew(self):
"""A full Crew of agents handles research."""
researcher = Agent(
role="Senior Research Analyst",
goal=f"Produce comprehensive research on: {self.state.topic}",
backstory="You're a veteran analyst known for thorough, "
"well-sourced research reports.",
llm="gpt-4o"
)
research_task = Task(
description=f"Research '{self.state.topic}' thoroughly. "
"Cover key trends, data points, and expert opinions.",
expected_output="A detailed research brief with sources.",
agent=researcher
)
crew = Crew(agents=[researcher], tasks=[research_task])
result = crew.kickoff()
self.state.research = result.raw
return result.raw
@listen(run_research_crew)
def run_writing_crew(self, research_output):
"""A different Crew handles writing."""
writer = Agent(
role="Technical Writer",
goal="Write a compelling article based on provided research.",
backstory="You turn complex research into engaging, clear prose.",
llm="gpt-4o"
)
editor = Agent(
role="Senior Editor",
goal="Review and polish articles for publication quality.",
backstory="20 years of editorial experience at top tech publications.",
llm="gpt-4o"
)
write_task = Task(
description=f"Write an article based on this research:\n{self.state.research}",
expected_output="A well-structured draft article.",
agent=writer
)
edit_task = Task(
description="Review, fact-check, and polish the draft article.",
expected_output="A publication-ready article.",
agent=editor
)
crew = Crew(agents=[writer, editor], tasks=[write_task, edit_task])
result = crew.kickoff()
self.state.final_article = result.raw
return result.raw
# Run the full pipeline
flow = ArticleFlow()
flow.state.topic = "The Future of Edge AI"
flow.kickoff()
print(flow.state.final_article)
```
Este é o insight-chave: **Flows fornecem a camada de orquestração, e Crews fornecem a camada de inteligência.** Cada etapa em um Flow pode subir uma equipe completa de agentes colaborativos, cada um com seus próprios papéis, objetivos e ferramentas. Você obtém fluxo de controle estruturado e previsível *e* colaboração autônoma de agentes — o melhor dos dois mundos.
No LangGraph, alcançar algo similar significa implementar manualmente protocolos de comunicação entre agentes, loops de chamada de ferramentas e lógica de delegação dentro das funções dos nós. É possível, mas é encanamento que você constrói do zero todas as vezes.
---
## Demo 4: Execução Paralela e Sincronização
Pipelines do mundo real frequentemente precisam dividir o trabalho e juntar os resultados. O CrewAI Flows lida com isso de forma elegante com os operadores `and_` e `or_`.
```python
from crewai import LLM
from crewai.flow.flow import Flow, and_, listen, start
from pydantic import BaseModel
llm = LLM(model="openai/gpt-5.2")
class AnalysisState(BaseModel):
topic: str = ""
market_data: str = ""
tech_analysis: str = ""
competitor_intel: str = ""
final_report: str = ""
class ParallelAnalysisFlow(Flow[AnalysisState]):
@start()
def start_method(self):
pass
@listen(start_method)
def gather_market_data(self):
# Your agentic or deterministic code
pass
@listen(start_method)
def run_tech_analysis(self):
# Your agentic or deterministic code
pass
@listen(start_method)
def gather_competitor_intel(self):
# Your agentic or deterministic code
pass
@listen(and_(gather_market_data, run_tech_analysis, gather_competitor_intel))
def synthesize_report(self):
# Your agentic or deterministic code
pass
flow = ParallelAnalysisFlow()
flow.state.topic = "AI-powered developer tools"
flow.kickoff()
```
Vários decorators `@start()` disparam em paralelo. O combinador `and_()` no decorator `@listen` garante que `synthesize_report` só execute depois que *todos os três* métodos upstream forem concluídos. Também existe `or_()` para quando você quer prosseguir assim que *qualquer* tarefa upstream terminar.
No LangGraph, você precisaria construir um padrão fan-out/fan-in com ramificações paralelas, um nó de sincronização e uma mesclagem de estado cuidadosa — tudo conectado explicitamente por arestas.
---
## Por que CrewAI Flows em Produção
Além de uma sintaxe mais limpa, Flows entrega várias vantagens críticas para produção:
**Persistência de estado integrada.** O estado do Flow é respaldado pelo LanceDB, o que significa que seus workflows podem sobreviver a falhas, ser retomados e acumular conhecimento entre execuções. No LangGraph, você precisa configurar um checkpointer separado.
**Gerenciamento de estado com segurança de tipos.** Modelos Pydantic oferecem validação, serialização e suporte de IDE prontos para uso. Estados `TypedDict` do LangGraph não validam em runtime.
**Orquestração de agentes de primeira classe.** Crews são um primitivo nativo. Você define agentes com papéis, objetivos, histórias e ferramentas — e eles colaboram de forma autônoma dentro do envelope estruturado de um Flow. Não é preciso reinventar a coordenação multiagente.
**Modelo mental mais simples.** Decorators declaram intenção. `@start` significa "comece aqui". `@listen(x)` significa "execute depois de x". `@router(x)` significa "decida para onde ir depois de x". O código lê como o workflow que ele descreve.
**Integração com CLI.** Execute flows com `crewai run`. Sem etapa de compilação separada, sem serialização de grafo. Seu Flow é uma classe Python, e ele roda como tal.
---
## Cheat Sheet de Migração
Se você está com uma base de código LangGraph e quer migrar para o CrewAI Flows, aqui vai um guia prático de conversão:
1. **Mapeie seu estado.** Converta seu `TypedDict` para um `BaseModel` do Pydantic. Adicione valores padrão para todos os campos.
2. **Converta nós em métodos.** Cada função de `add_node` vira um método na sua subclasse de `Flow`. Substitua leituras `state["field"]` por `self.state.field`.
3. **Substitua arestas por decorators.** `add_edge(START, "first_node")` vira `@start()` no primeiro método. A sequência `add_edge("a", "b")` vira `@listen(a)` no método `b`.
4. **Substitua arestas condicionais por `@router`.** A função de roteamento e o mapeamento do `add_conditional_edges()` viram um único método `@router()` que retorna a string de rota.
5. **Troque compile + invoke por kickoff.** Remova `graph.compile()`. Chame `flow.kickoff()`.
6. **Considere onde as Crews se encaixam.** Qualquer nó com lógica complexa de agentes em múltiplas etapas é um candidato a extração para uma Crew. É aqui que você verá a maior melhoria de qualidade.
---
## Primeiros Passos
Instale o CrewAI e crie o scaffold de um novo projeto Flow:
```bash
pip install crewai
crewai create flow my_first_flow
cd my_first_flow
```
Isso gera uma estrutura de projeto com uma classe Flow pronta para edição, arquivos de configuração e um `pyproject.toml` com `type = "flow"` já definido. Execute com:
```bash
crewai run
```
A partir daí, adicione seus agentes, conecte seus listeners e publique.
---
## Considerações Finais
O LangGraph ensinou ao ecossistema que workflows de IA precisam de estrutura. Essa foi uma lição importante. Mas o CrewAI Flows pega essa lição e a entrega de um jeito mais rápido de escrever, mais fácil de ler e mais poderoso em produção — especialmente quando seus workflows envolvem múltiplos agentes colaborando.
Se você está construindo algo além de uma cadeia de agente único, dê uma olhada séria no Flows. O modelo baseado em decorators, a integração nativa com Crews e o gerenciamento de estado embutido significam menos tempo com encanamento e mais tempo nos problemas que importam.
Comece com `crewai create flow`. Você não vai olhar para trás.

Quando você especifica `emit`, o decorador se torna um roteador. O feedback livre do humano é interpretado por um LLM e mapeado para um dos outcomes especificados:

@listen("rejected")
def discard(self, result):
print(f"Descartando. Motivo: {result.feedback}")
```
Quando o humano diz algo como "precisa de mais detalhes", o LLM mapeia para `"needs_revision"`, que dispara `review_content` novamente via `or_()` — criando um loop de revisão. O loop continua até que o outcome seja `"approved"` ou `"rejected"`.
<Tip>
O LLM usa saídas estruturadas (function calling) quando disponível para garantir que a resposta seja um dos seus outcomes especificados. Isso torna o roteamento confiável e previsível.
</Tip>
<Warning>
Um método `@start()` só executa uma vez no início do flow. Se você precisa de um loop de revisão, separe o método start do método de revisão e use `@listen(or_("trigger", "revision_outcome"))` no método de revisão para habilitar o self-loop.

## Combinando com Outros Decoradores
O decorador `@human_feedback` funciona com outros decoradores de flow. Coloque-o como o decorador mais interno (mais próximo da função):
O decorador `@human_feedback` funciona com `@start()`, `@listen()` e `or_()`. Ambas as ordens de decoradores funcionam — o framework propaga atributos em ambas as direções — mas os padrões recomendados são:
```python Code
# Correto: @human_feedback é o mais interno (mais próximo da função)
# Revisão única no início do flow (sem self-loop)
@start()
@human_feedback(message="Revise isto:")
@human_feedback(message="Revise isto:", emit=["approved", "rejected"], llm="gpt-4o-mini")
def my_start_method(self):
return "content"
# Revisão linear em um listener (sem self-loop)
@listen(other_method)
@human_feedback(message="Revise isto também:")
@human_feedback(message="Revise isto também:", emit=["good", "bad"], llm="gpt-4o-mini")
def my_listener(self, data):
return f"processed: {data}"
# Self-loop: revisão que pode voltar para revisões
@human_feedback(message="Aprovar ou revisar?", emit=["approved", "revise"], llm="gpt-4o-mini")
@listen(or_("upstream_method", "revise"))
def review_with_loop(self):
return "content for review"
```
<Tip>
Coloque `@human_feedback` como o decorador mais interno (último/mais próximo da função) para que ele envolva o método diretamente e possa capturar o valor de retorno antes de passar para o sistema de flow.
</Tip>
### Padrão de self-loop
Para criar um loop de revisão, o método de revisão deve escutar **ambos** um gatilho upstream e seu próprio outcome de revisão usando `or_()`:
```python Code
@start()
def generate(self):
return "initial draft"
@human_feedback(
message="Aprovar ou solicitar alterações?",
emit=["revise", "approved"],
llm="gpt-4o-mini",
default_outcome="approved",
)
@listen(or_("generate", "revise"))
def review(self):
return "content"
@listen("approved")
def publish(self):
return "published"
```
Quando o outcome é `"revise"`, o flow roteia de volta para `review` (porque ele escuta `"revise"` via `or_()`). Quando o outcome é `"approved"`, o flow continua para `publish`. Isso funciona porque o engine de flow isenta roteadores da regra "fire once", permitindo que eles re-executem em cada iteração do loop.
### Roteadores encadeados
Um listener disparado pelo outcome de um roteador pode ser ele mesmo um roteador:
```python Code
@start()
@human_feedback(message="Primeira revisão:", emit=["approved", "rejected"], llm="gpt-4o-mini")
def draft(self):
return "draft content"
@listen("approved")
@human_feedback(message="Revisão final:", emit=["publish", "revise"], llm="gpt-4o-mini")
def final_review(self, prev):
return "final content"
@listen("publish")
def on_publish(self, prev):
return "published"
```
### Limitações
- **Métodos `@start()` executam uma vez**: Um método `@start()` não pode fazer self-loop. Se você precisa de um ciclo de revisão, use um método `@start()` separado como ponto de entrada e coloque o `@human_feedback` em um método `@listen()`.
- **Sem `@start()` + `@listen()` no mesmo método**: Esta é uma restrição do framework de Flow. Um método é ou um ponto de início ou um listener, não ambos.

tools = toolset.get_tools(apps=[App.GITHUB])
connection_request = session.authorize("github")
print(f"Open this URL to authenticate: {connection_request.redirect_url}")
```
- Filtrando ferramentas com base em tags:
```python Code
tag = "users"
filtered_action_enums = toolset.find_actions_by_tags(
App.GITHUB,
tags=[tag],
)
tools = toolset.get_tools(actions=filtered_action_enums)
```
- Filtrando ferramentas com base no caso de uso:
```python Code
use_case = "Star a repository on GitHub"
filtered_action_enums = toolset.find_actions_by_use_case(
App.GITHUB, use_case=use_case, advanced=False
)
tools = toolset.get_tools(actions=filtered_action_enums)
```
<Tip>Defina `advanced` como True para obter ações para casos de uso complexos</Tip>
- Usando ferramentas específicas:
Neste exemplo, usaremos a ação `GITHUB_STAR_A_REPOSITORY_FOR_THE_AUTHENTICATED_USER` do app GitHub.
```python Code
tools = toolset.get_tools(
actions=[Action.GITHUB_STAR_A_REPOSITORY_FOR_THE_AUTHENTICATED_USER]
)
```
