Show HN: HiTank – A skill manager for Claude Code, written in pure Ruby (github.com)

A new tool called HiTank has been released, enabling users to manage AI skills for Claude Code using pure Ruby. The CLI allows users to easily install, add, or remove skills related to various services such as Google Sheets, Jira, and Slack, promoting a more straightforward approach to building AI tooling without relying on languages like Python or TypeScript. Users can simply execute commands like `gem install hitank` to get started, making it accessible for those familiar with Ruby. This development is significant for the AI/ML community as it showcases how effective and lightweight Ruby can be for creating AI applications, with a focus on minimizing code complexity and dependencies. HiTank's design optimizes for lower token usage in Claude by reducing the amount of code needed to interact with REST APIs, which can lead to cost savings in API consumption. By leveraging Ruby's standard library, the tool offers a robust solution for developers looking to efficiently manage and deploy AI skills while maintaining simplicity and performance.
