During November 2025, Jaune Malukaite initiated groundwork for the Gemini-3 Preview feature in the CMBAgents/cmbagent repository. Jaune established a dedicated feature branch and opened a draft pull request to enable early integration and collaborative review of Gemini-3 preview functionality. The approach focused on isolating development from the mainline, supporting incremental delivery and risk assessment without disrupting ongoing work. Using Git for version control and feature-branch workflows, Jaune demonstrated proficiency in collaborative software development practices. While no bugs were fixed during this period, the work laid a technical foundation for future Gemini-3 feature parity and streamlined product roadmap alignment.
