asyncio.run(main())

📋 Use Cases

1. Code Review Voting 👨‍💻

Perfect for collaborative code reviews with multiple reviewers:

# Qualified majority voting for code reviews
voting_team = VotingGroupChat(
    participants=[senior_dev, security_expert, performance_engineer],
    voting_method=VotingMethod.QUALIFIED_MAJORITY,
    qualified_majority_threshold=0.67,  # Require 2/3 approval
    require_reasoning=True
)

task = """
Proposal: Approve merge of PR #1234 - "Add Redis caching layer"

Code changes implement memory caching to reduce database load.
Please review for: security, performance, maintainability.

Vote APPROVE or REJECT with detailed reasoning.
"""

2. Architecture Decisions 🏗️

Use ranked choice voting for complex architectural decisions:

# Ranked choice for architecture decisions
voting_team = VotingGroupChat(
    participants=[tech_lead, architect, devops_engineer],
    voting_method=VotingMethod.RANKED_CHOICE,
    max_discussion_rounds=3
)

task = """
Proposal: Choose microservices communication pattern

Options:
1. REST APIs with Service Mesh
2. Event-Driven with Message Queues  
3. GraphQL Federation
4. gRPC with Load Balancing

Provide ranked preferences with reasoning.
"""

3. Content Moderation 🛡️

Majority voting for content approval/rejection:

# Simple majority for content moderation
voting_team = VotingGroupChat(
