-\n## Task Tracking\n\
-You have built-in task tracking tools. Use them to track your progress:\n\
-- `todo__init`: Initialize a todo list with a goal. Call this at the start of every multi-step task.\n\
-- `todo__add`: Add individual tasks. Add all planned steps before starting work.\n\
-- `todo__done`: Mark a task done by id. Call this immediately after completing each step.\n\
-- `todo__list`: Show the current todo list.\n\
-\n\
-RULES:\n\
-- Always create a todo list before starting work.\n\
-- Mark each task done as soon as you finish it; do not batch.\n\
-- If you stop with incomplete tasks, the system will automatically prompt you to continue.";
