Developed a robust enhancement for the moltbot/moltbot repository’s Daily Token Usage and Cost Chart, focusing on complete calendar-day representation and improved data reliability. Leveraging TypeScript and full stack development skills, the work introduced DST-safe, calendar-day iteration anchored at local noon to prevent gaps during daylight saving transitions. The solution capped zero-filled days at 366 to avoid payload bloat, maintaining sparse output for extended ranges. Comprehensive regression testing ensured all changes were stable, with 42 tests passing and no lint issues. Collaboration with other contributors facilitated thorough code review and approval, resulting in a more reliable analytics experience for users.
