During March 2026, contributed two core features across the gsd-build/get-shit-done and sst/opencode repositories, focusing on model flexibility and prompt reliability. Developed a dynamic inheritance model profile option for GSD agents, enabling runtime selection of models for safer and more flexible integration. In sst/opencode, implemented deterministic prompt ordering for agents and skills, ensuring stable and predictable outputs while simplifying debugging. Enhanced reliability by adding targeted tests to confirm prompt stability across multiple calls. Leveraged Node.js and TypeScript in a full stack context, collaborating across teams to deliver features that improved runtime adaptability and increased confidence in prompt regeneration scenarios.
