Why Aider scores 3.7
Aider excels as a terminal-based pair programming tool with exceptional integration capabilities, particularly with Git (automatic commits with sensible messages), 100+ programming languages, and IDE integration. Its codebase mapping feature helps it understand larger projects, and the high singularity metric (88% of its own code written by itself) demonstrates strong code quality capabilities. The tool's strength lies in collaborative development within existing codebases rather than fully autonomous execution.

Why Roo Code scores 3.8
Roo Code demonstrates strong autonomy capabilities as an 'AI dev team' that provides multi-step agentic coding with project-wide context understanding. The tool appears designed for independent task execution across multiple files and components, positioning itself as more than a simple code completion tool. However, without detailed documentation or demos visible from the website content, the full extent of its autonomous capabilities remains somewhat unclear, leading to a solid but not perfect autonomy score.
