Waza

Engineering habits you already know, turned into skills Claude can run.

Why

Waza (技, わざ) is a Japanese martial arts term for technique: a move practiced until it becomes instinct.

A good engineer does not just write code. They think through requirements, review their own work, debug systematically, design interfaces that feel intentional, and read primary sources. They write clearly, and learn new domains by producing output, not consuming content.

AI makes you faster. It doesn't make you think more clearly, ship more carefully, or understand more deeply. Waza packages these habits into skills Claude can run.

Skills

Each engineering habit gets a [Claude Code skill](https://docs.anthropic.com/en/docs/claude-code/skills). Type the slash command, Claude follows the playbook.

Skill	When	What it does
`/think`	Before building anything new	Challenges the problem, pressure-tests the design, validates architecture before any code is written.
`/design`	Building frontend interfaces	Produces distinctive UI with a committed aesthetic direction, not generic defaults.
`/check`	After a task, before merging	Reviews the diff, auto-fixes safe issues, blocks destructive commands, verifies with evidence.
`/hunt`	Any bug or unexpected behavior	Systematic debugging. Root cause confirmed before any fix is applied.
`/write`	Writing or editing prose	Rewrites prose to sound natural in Chinese and English. Cuts stiff, formulaic phrasing.
