| Kai's verdict | GitNexus solves a real and underappreciated problem: AI coding agents are syntactically fluent but architecturally blind, and plugging a pre-computed knowledge graph into the MCP layer is the right fix. 28k GitHub stars in days suggests the pain is widely felt — just go in knowing it's a community project, not a polished product. (Verdict pending Phi's full review.) | A-tier for sales teams. B-tier for solo users. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it. |
