Kakuna: An AI Agent Tool for Automated Codebase Hardening

Kakuna：自动化加固代码库的AI代理工具

Kakuna hardens prototype codebases with built-in checklists and a plan-goal workflow; one roughly 16-hour run can generate hundreds of commits while preserving functionality.

Why it matters: HKR-H/K/R all pass: the post has a 16-hour run, hundreds of commits, and a workflow mechanism tied to coding-agent pain. Single X source and a non-major vendor keep it at the featured threshold.
