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.
