| 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.) | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | A-tier for designer-led sites. S-tier if animations matter. | A-tier for ops automation. B-tier for simple copy (use Claude). |
