Review recent conversations with the CircleCI docs bot (Kapa) to find content gaps, wrong answers, and questions the bot could not answer. Fixes what can be fixed in docs by opening pull requests, and reports everything else with a category. Use when the user asks to review Kapa conversations, find docs gaps from the bot, run the weekly Kapa review, or check what the bot could not answer. Takes an optional period, such as "last 7 days" (default) or "last 6 weeks".
