Content about #Claude Code

The Ralph Loop technique — a trick for making AI Coding Agents automatically repeat execution — was popular last year, but I didn’t trust whether it was safe enough or sufficiently stable.

A few months ago, Claude Code’s update introduced the /loop skill, which essentially uses Claude Code’s built-in Cron tool to repeat specific prompts at fixed intervals, achieving a similar effect. At least it’s safer and more controllable.

However, things are rarely that simple.

Have you seen Claude Code’s Sub-Agent feature and immediately wanted to design a bunch of them? Backend Agent, Frontend Agent, and so on—it feels like getting more powerful tools. But do you really need them?

During WebConf 2025, chatting with friends about this topic revealed that many people are still unfamiliar with when to use Sub-Agents. Two talks at the conference provided good entry points: ihower’s AI Agents Development and 91APP’s Chief Architect Andrew’s From Service to Agent.

Recently, the Hono framework launched the Hono CLI tool, and I quickly created a Hono Plugin for Claude Code, adding Agent Skill support for querying documentation using Hono CLI.

At the same time, I realized that the ri (Ruby Information) command, which I rarely use, provides similar capabilities to the Hono CLI. Therefore, I created the Ruby Plugin ahead of schedule to provide the ri skill.

I was originally planning to release a tool that applied techniques from my COSCUP talk in August. However, I discovered that there are many considerations in development, and practical usage has its barriers.

I decided to start from a simpler, more immediately accessible angle. Recently, I finally completed the basic functionality of ccharness, which can improve Claude Code’s output quality from a different perspective.
