Jan 1, 2026January 2026 monthly summary for planetscale/cli: Key features delivered, major bugs fixed, overall impact, and technologies demonstrated. Key features delivered: - Service tokens governance: TTL support and enhanced permission checks across all role commands; TTL flag added to service token create (commits: 9e828a7, 7a3bee2). - MySQL cluster configuration: updated replica count to 2 with corresponding test adjustments (commit: 8721fc0e). - ListCmd robustness: improved error handling and readability during API calls for listing cluster SKUs (commits: 0d1bae0, ec826e0) and linting improvements. Major bugs fixed: - ListCmd resilience: stronger error handling to endure API call failures when listing MySQL/PostgreSQL SKUs; improved CLI readability (commits: 0d1bae0e, ec826e0). - MySQL replica count fix: align cluster config to 2 replicas and update tests accordingly (commit: 8721fc0e). Overall impact and accomplishments: - Higher CLI reliability during SKU listings, reduced runtime errors, and clearer user feedback. - Cost and ops optimization from downsizing MySQL replicas while maintaining validation coverage. - Strengthened security and usability with TTL-enabled tokens and formal permission checks. Technologies/skills demonstrated: - Go CLI development, robust error handling, linting, test-driven updates, RBAC and TTL-based token workflows.

Sep 1, 20252025-09 Monthly Summary for planetscale/cli: Delivered reliability and efficiency improvements for database readiness. Extended timeouts for database branch readiness and creation readiness to accommodate slower provisioning and implemented dynamic polling to reduce API load during branch creation waiting. Increased the db create --wait timeout to prevent premature timeouts. These changes improve provisioning reliability in slower environments, reduce API churn, and enhance the user experience when creating branches and databases.
