A complete agent

apiVersion: v1
runtime: python3.12
entrypoint: agent.py:crew
dependencies: requirements.txt

crewai>=1.0

from crewai import LLM, Agent, Crew, Task

# Reads OPENAI_API_KEY, which you add as a secret on the agent's Config tab.
llm = LLM(model="openai/gpt-5", stream=True)

researcher = Agent(
    role="Researcher",
    goal="Find the key facts about {topic}",
    backstory="You research topics thoroughly.",
    llm=llm,
)

research = Task(
    description="Research {topic} and list the five most important facts.",
    expected_output="Five facts about {topic}, one per line.",
    agent=researcher,
)

crew = Crew(agents=[researcher], tasks=[research])

​

The prompt and the reply

• One placeholder, such as {topic}: the prompt fills it.
• Several: the prompt fills the first of {topic}, {question}, {input} or {query} that appears.
• Several, none with those names: the call fails with a message listing them. Rename one, or wrap the crew in a function that builds the inputs.
• None: the crew runs with no inputs.

​

Events it reports

​

The caller’s fields

def agent(prompt: str, request: dict) -> str:
    params = request["params"]
    return crew.kickoff(inputs={"topic": prompt, "audience": params.get("audience", "general")}).raw

​

Known limits

• CrewAI reports no tool results, so tool calls appear without their outputs.
• A crew whose model does not stream sends its answer once, at the end, with no tool calls.
• A crew with several placeholders and none named topic, question, input or query needs a function wrapper.
