Worked on the inbox-zero repository to enhance reliability and data integrity by updating the SaveMemory tool schema for provider compatibility. Focused on enforcing userEvidence requirements for user messages, these changes aimed to reduce schema drift and streamline integration with external providers. Collaborated cross-functionally to ensure the schema aligned with provider expectations, improving interoperability and maintainability. Utilized TypeScript and Zod validation to implement and test the schema updates, prioritizing backend robustness over new user-facing features. This foundational work addressed a key bug and established a more stable base for future enhancements, supporting easier onboarding and smoother provider integration moving forward.
