Developed a targeted enhancement for the sst/opencode repository, focusing on improved Trinity model support within the CLI tool. The work introduced a dedicated Trinity-specific system prompt, implemented as a new prompt file, and updated the CLI’s prompt logic to ensure consistent and deterministic behavior for Trinity users. Leveraging TypeScript and full stack development skills, the solution anchored prompt handling for the Trinity model, making interactions more reliable and maintainable. The approach emphasized traceable contributions through focused commits and collaborative development. This feature addressed the need for clearer guidance and predictable outcomes when using the Trinity model in CLI environments.
