arbor vs nex-as-a-skill

arbor: Arbor builds a semantic dependency graph for codebases, enabling deterministic impact analysis, symbol resolution, and git-aware risk gating. It provides a CLI, GUI, and MCP integration to help developers understand and control the consequences of changes before they happen.; nex-as-a-skill: Nex is an intelligence layer for AI agents that provides a unified knowledge graph across different tools. It allows you to store information from one agent and recall it from any other, eliminating the need to re-explain context. It supports multiple AI platforms and integrates with various data sources.
