Code kata involves daily timed practice of specific code routines and patterns to increase speed and memory without advancing prematurely. Practitioners perform alone, in pairs, or groups, always starting from scratch for a minimum of 15 and maximum of 30 minutes to improve skills through repetition while tracking progress over time. Ground rules require participants to not skip ahead, leave no one behind by waiting for discussion, and restart from the beginning at each session rather than continuing unfinished work.
