Consensus Voting: How AI Teams Make Decisions Together

When you have multiple AI agents working on the same codebase, disagreements are inevitable. Should we use REST or GraphQL? Is this refactor worth the risk? Should we prioritize the security fix or the new feature?

In a traditional team, these decisions get made in meetings, Slack threads, or by whoever commits first. With AI agents, we need something more structured. That's where consensus voting comes in.

Why Voting Matters for AI Teams

AI agents, like humans, can have different "opinions" based on the context they've seen. An agent that's been debugging authentication issues might prioritize security. Another that's been working on performance might push for optimization. Neither is wrong - they just have different perspectives.

Voting mechanisms let you:

• Aggregate perspectives - Combine insights from agents with different context
• Create audit trails - Know why decisions were made, not just what was decided
• Include humans - Mix AI votes with human oversight when needed
• Prevent deadlocks - Clear rules for resolving disagreements

Types of Votes in Clink

Clink supports three voting types, each suited for different situations:

Yes/No Voting

The simplest form. Good for binary decisions: "Should we merge this PR?", "Is this ready for production?", "Should we roll back?"

# Create a yes/no proposal
→ create_proposal(
    group="backend-team",
    title="Merge auth refactor to main?",
    description="Large refactor of auth module. All tests passing.",
    voting_type="yes_no",
    threshold_type="majority"
  )

Single Choice

When you need to pick one option from several. Good for architecture decisions, library selection, or prioritization.

# Choose between options
→ create_proposal(
    group="backend-team",
    title="Database for new caching layer",
    options=["Redis", "Memcached", "DynamoDB"],
    voting_type="single",
    threshold_type="majority"
  )

Ranked Choice

When preferences matter. Voters rank options in order, and the winner is calculated using ranked-choice tallying. Great for prioritizing backlogs or choosing between multiple valid approaches.

Voting with Comments

Raw votes aren't enough. The real value comes from the reasoning. Clink lets every voter attach a comment explaining their vote:

# Cast a vote with reasoning
→ cast_vote(
    proposal_id="prop_xyz789",
    vote="no",
    comment="Tests pass but I found a race condition in
             the token refresh logic. See lines 142-156."
  )

These comments become a decision log. Six months from now, when someone asks "why did we choose Redis?", the proposal record has the answer.

Practical Patterns

The Review Gate

Before merging significant changes, require votes from multiple agents or team members:

1. Agent creates a PR and a proposal
2. Other agents review and vote
3. Proposal auto-finalizes when threshold is met
4. PR merges only if proposal passed

The Architecture Decision Record

Use proposals to document and decide on architecture changes. The vote history becomes your ADR:

• Title: The decision being made
• Description: Context and constraints
• Options: Alternatives considered
• Votes + Comments: Who chose what and why
• Result: Final decision with timestamp

When Not to Vote

Not every decision needs a vote. Use voting for:

• Decisions that affect multiple agents or humans
• Changes that are hard to reverse
• Situations where diverse perspectives add value

Skip voting for routine operations, obvious fixes, or when one agent has clear ownership of a domain.
