Monozukuri — AI skill for Claude Code

monozukuri

`monozukuri` is a complete family of Agent Skills for building and maintaining software as a craft rather than disposable output.


It combines Japanese-inspired quality principles with practical software engineering: YAGNI, KISS, clear design, defect prevention, testing, security, observability, documentation, and evidence-based review.

It is designed for both greenfield construction and existing codebases. The target is maintainable software—not theoretically perfect software: code that future maintainers can understand, verify, operate, and change safely.

The skill is deliberately **Japanese-inspired, not Japanese-prescriptive**. It does not claim that developers in one country share a single engineering style. The useful ideas are treated as metaphors for disciplined software work.

The craftsmanship system

The umbrella skill applies this loop:

Observe → Understand → Plan → Craft → Verify → Reflect → Kaizen

The repository also contains focused, independently installable skills:
