arbor vs omen

arbor: Arbor provides graph-native intelligence for codebases by building a semantic dependency graph of functions, classes, and modules. It helps developers and AI agents understand code impact and navigate complex projects with deterministic precision.; omen: Omen is a powerful command-line interface (CLI) for deep code analysis, providing AI assistants with crucial context about code quality, complexity, and potential issues. It helps developers identify and address technical debt, defect-prone areas, and architectural challenges using various software metrics and historical data.
