name: fusion-algorithm description: Compare multiple algorithm options and pick the best; use when choosing or optimizing an algorithm.

Fusion Algorithm

Overview

Use an F-thread: three workers in separate git worktrees plus a judge queen. Each worker implements the algorithm differently. The queen compares and selects a winner.

Inputs

• Algorithm description

Workflow

1. Verify git and mprocs.
2. Create session variables:
   • SESSION_ID, BASE_BRANCH, PROJECT_ROOT, WORKTREE_ROOT
3. Create .hive/sessions/<session-id> and WORKTREE_ROOT.
4. Create worktrees:

git worktree add "{WORKTREE_ROOT}/impl-a" -b fusion/{SESSION_ID}/impl-a
git worktree add "{WORKTREE_ROOT}/impl-b" -b fusion/{SESSION_ID}/impl-b
git worktree add "{WORKTREE_ROOT}/impl-c" -b fusion/{SESSION_ID}/impl-c

1. Write tasks.json and worker prompts.
2. Write .hive/mprocs.yaml and launch mprocs.

  }
}

Worker Prompt Outline

• Worker A: clean, readable implementation
• Worker B: alternative approach or data structure
• Worker C: performance-focused implementation

Queen Prompt Outline

• Compare correctness, complexity, readability, and test results
• Pick a winner or merge best elements

mprocs Launch

mprocs --config .hive/mprocs.yaml

Output

• Three implementations in worktrees and a final evaluation
