CrewAI integration

Use QWEDVerifiedAgent and QWEDVerificationTool with CrewAI for verified multi-agent systems. Ensure agent outputs are mathematically correct before execution.

​

Installation

pip install qwed crewai

​

Quick start

from crewai import Task, Crew
from qwed_sdk.crewai import QWEDVerifiedAgent

# Create a verified agent
analyst = QWEDVerifiedAgent(
    role="Financial Analyst",
    goal="Perform accurate financial calculations",
    backstory="Expert in financial modeling",
)

# Use in CrewAI workflow
task = Task(
    description="Calculate compound interest for $10,000 at 5% for 10 years",
    agent=analyst.agent
)

crew = Crew(agents=[analyst.agent], tasks=[task])
result = crew.kickoff()

​

QWEDVerificationTool

Give agents verification capabilities:

from crewai import Agent
from qwed_sdk.crewai import QWEDVerificationTool

agent = Agent(
    role="Data Analyst",
    goal="Verify calculations",
    tools=[QWEDVerificationTool()]
)

​

Specialized tools

from qwed_sdk.crewai import QWEDMathTool, QWEDCodeTool, QWEDSQLTool

agent = Agent(
    role="Developer",
    goal="Write secure code",
    tools=[
        QWEDMathTool(),   # Math verification
        QWEDCodeTool(),   # Code security
        QWEDSQLTool(),    # SQL validation
    ]
)

​

QWEDVerifiedAgent

Agent wrapper with automatic verification:

from qwed_sdk.crewai import QWEDVerifiedAgent, VerificationConfig

analyst = QWEDVerifiedAgent(
    role="Analyst",
    goal="Accurate analysis",
    backstory="...",
    verification_config=VerificationConfig(
        enabled=True,
        verify_math=True,
        verify_code=True,
        auto_correct=False,
        log_results=True,
    )
)

# Check verification summary
print(analyst.verification_summary())
# {"total_outputs": 5, "verified": 4, "failed": 1}

verify_output() starts every output as unverified. It sets verified: True only when the client’s is_verified is True, which follows the server’s admission:

Case	verified	status
The server admits the output	True	Server status, for example VERIFIED
The server does not admit the output	False	Server status, for example UNVERIFIABLE
VerificationConfig(enabled=False)	False	SKIPPED
The check raises an error	False	ERROR

verification_summary() counts only outputs with verified: True.

Before v8.0.0 (GHSA-83v6-6h23-pvp4), verify_output() started from verified: True and kept it when the check raised or verification was disabled. Don’t rely on verified=True or verification rates from earlier versions.

​

QWEDVerifiedCrew

Verify entire crew outputs:

from qwed_sdk.crewai import QWEDVerifiedCrew

crew = QWEDVerifiedCrew(
    agents=[analyst, writer],
    tasks=[task1, task2],
    verify_final_output=True,
)

result = crew.kickoff()
print(result.verified)  # True/False
print(result.overall_verification_rate)  # 0.95

​

Task decorator

from qwed_sdk.crewai import verified_task

@verified_task(verify_output=True)
def process_result(output):
    # Output is verified before this runs
    return output.upper()
