The Take
The agent security failure at GitHub and the cost-driven migration toward Chinese open-weight models are converging: teams cutting API spend by routing to cheaper or self-hosted models will simultaneously expand their attack surface if they carry forward the same permissive tool-access patterns. Scope restriction and prompt injection hardening are now prerequisite, not optional, for any agentic deployment.
