September 2025 highlights for google-gemini/gemini-cli: delivered end-to-end Todo and Task Management capabilities with CLI task tracking, structured lists and subtasks, and integration with system prompts and configuration to support task planning workflows. Prominent enhancements include Prompts and System Prompt Enhancements for Todo Tools with configuration-driven prompts and improved guidance for software engineering tasks, plus documentation and tooling refinements. Addressed robustness and scope changes with important fixes and cleanup: Todo default handling now defaults to an empty array when none are provided, and references to the Write Todos/TODO tool were removed from prompts to reflect the updated core prompt scope. Overall impact includes improved task planning within the CLI, reduced runtime errors, and clearer, more maintainable prompts and docs. Technologies and skills demonstrated include WriteTodos tool refactor, system prompt configuration, prompt-driven workflows, and documentation improvements.
