Before Adding Gemma 4 to MonkeyCode, Run a Model Capability Contract
Short summary
A source-code review of MonkeyCode's model integration flow that identifies a gap: its health check only verifies API reachability, not protocol behavior or capability correctness. The article proposes a four-gate readiness model (transport, protocol, capability, task quality) and provides a Node.js probe script that tests system-role compliance, streaming, and tool-call support. It is framed around preparing for Gemma 4 integration but applies to any model addition.
- •MonkeyCode's health check only verifies transport (API reachability), not protocol or capability correctness
- •Proposes four-gate model readiness: transport, protocol, capability, task quality
