B3ehive

Runs three AI agents in parallel to implement, cross-evaluate, score, and select the best code solution for a given coding task objectively.

b3ehive Skill Specification

PCTF-Compliant Multi-Agent Competition System

---

1. Purpose (PCTF: Purpose)

Enable competitive code generation where three isolated AI agents implement the same functionality, evaluate each other objectively, and deliver the optimal solution through data-driven selection.

---

2. Task Definition (PCTF: Task)

Input

• task_description: String describing the coding task
• constraints: Optional constraints (time/space complexity, language, etc.)

Output

• final_solution: Directory containing the winning implementation
• comparison_report: Markdown analysis of all three approaches
• decision_rationale: Explanation of why the winner was selected

Success Criteria

assertions:
  - final_solution/implementation exists and is runnable
  - comparison_report.md exists with objective metrics
  - decision_rationale.md explains selection logic
  - all three agent implementations are documented
  - evaluation scores are numeric and justified

    comparison: "{{objective_comparison}}"

final_conclusion:
  best_implementation: "[A/B/C/Mixed]"
  reasoning: "{{data_driven_justification}}"
  recommendation: "{{delivery_strategy}}"

assertions:
  - all scores are numeric
  - justifications are specific
  - no inflation or bias
  - conclusion is evidence-based

Phase 4: Final Delivery

Decision Logic:

def select_winner(scores):
    """
    Select final solution based on competitive scores
    """
    margins = calculate_score_margins(scores)
    
    if margins.winner - margins.second > 15:
        # Clear winner
        return SingleWinner(scores.winner)
    elif margins.winner - margins.second > 5:
        # Close competition, consider hybrid
        return HybridSolution(scores.top_two)
    else:
        # Very close, pick simplest
        return SimplestImplementation(scores.all)

assertions:
  - final_solution is runnable
  - comparison_report explains all approaches
  - decision_rationale is transparent
  - attribution is given to winning agent
