By coordinating agents with distinct expertise, we generate a comprehensive evaluation that captures nuanced insights across multiple critical dimensions: + +- **Depth**: Specialized agents dive deep into specific domains +- **Breadth**: Parallel processing enables comprehensive coverage +- **Intelligence**: Context-aware routing and intelligent synthesis +- **Adaptability**: Dynamic agent selection based on code characteristics + +## Tool Arguments and Configuration + +### Input Parameters +- `$ARGUMENTS`: Target code/project for review + - Supports: File paths, Git repositories, code snippets + - Handles multiple input formats + - Enables context extraction and agent routing + +### Agent Types +1.

Best Practices Experts + +## Multi-Agent Coordination Strategy + +### 1. Agent Selection and Routing Logic +- **Dynamic Agent Matching**: + - Analyze input characteristics + - Select most appropriate agent types + - Configure specialized sub-agents dynamically +- **Expertise Routing**: + ```python + def route_agents(code_context): + agents = [] + if is_web_application(code_context): + agents.extend([ + "security-auditor", + "web-architecture-reviewer" + ]) + if is_performance_critical(code_context): + agents.append("performance-analyst") + return agents + ``` + +### 2.
