Parallel Bug-Fix with Test Validation

Usage

Invoke with: /parallel-bugfix [bug description]

Workflow

1. Analyze the bug — identify the suspected root cause file(s) and symptoms
2. Spawn 3 parallel sub-agents using the Task tool, each in a worktree (isolation: "worktree"):

Agent 1: Minimal Targeted Fix

• Fix only the suspected root cause with the smallest possible change
• Run build/lint after edit
• Report pass/fail + diff size

Agent 2: Refactor to Eliminate Bug Class

• Refactor the surrounding code to make the bug class impossible
• Run build/lint after edit
• Report pass/fail + diff size

Agent 3: Component Rewrite (if <200 lines)

• Rewrite the affected component from scratch
• If component is >200 lines, skip this agent and report "too large to rewrite"
• Run build/lint after edit
• Report pass/fail + diff size

3. Compare results from all 3 agents:
   • Pick the approach that passes all checks with the smallest diff
   • If none pass, synthesize the best elements into a final fix
4. Apply the winning fix to the main working tree
5. Run final validation — build + lint + any existing tests

Rules

• Each agent gets MAX 200 lines of code changes
• Always run build verification before declaring success
• If all 3 fail, report findings and ask user for direction
