Teaching web development and AI: project-based lessons at KakkoiSchool, from HTML and CSS to React, Next.js and AI, and AI GUILD IZUMO, a community to learn, build and share with AI.
Building tools for learning Japanese: Echo, which turns an English sentence into Japanese to learn by shadowing; Minihongo, 231 words to express any idea; and Anki decks with natural audio. JP Core is the library they share.
Making AI coding agents easier to run and to trust: Jikko keeps the plan, the progress and the proof of work in plain Markdown, Intent Driven Development specifies work so agents implement it faithfully, and the tmux agent tools run many agents side by side.
