name: fusion-refactor description: Compare refactoring approaches and pick the safest path; use when multiple refactor strategies are possible.

Fusion Refactor

Overview

Use an F-thread: three workers propose different refactor strategies in separate worktrees. The queen selects the safest path.

Inputs

• Refactor goal and constraints

Workflow

1. Verify git and mprocs.
2. Create session variables and worktrees.
3. Write tasks.json, worker prompts, and queen prompt.
4. Launch mprocs.

Worktree Commands

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

Worker Prompt Outline

• Worker A: incremental refactor
• Worker B: module-by-module
• Worker C: larger rewrite with safeguards

Queen Prompt Outline

• Compare risk, test impact, and migration cost

mprocs Launch

mprocs --config .hive/mprocs.yaml

Output

• Selected refactor strategy and staged plan
