const SIMPLIFY_PROMPT = `# Simplify: Code Review

Review all changed files for reuse,
quality, and efficiency. Fix issues.

## Phase 1: Identify Changes
Run \`git diff\` to see what changed.

## Phase 2: Launch Three Review Agents
Use AgentTool to launch all three
agents concurrently:

### Agent 1: Code Reuse Review
- Search for existing utilities
- Flag duplicate functionality

### Agent 2: Code Quality Review
- Redundant state, parameter sprawl

### Agent 3: Efficiency Review
- Algorithmic efficiency issues
