Introducing Han: Master Your Craft with Claude Code

The Problem with Developer Tools Today

Most developer tools follow the same playbook: add every feature possible, overwhelm users with options, and hope something sticks. The result? Bloated tools that slow you down instead of speeding you up.

We built Han because we needed something better.

What is Han?

Han is a curated marketplace of plugins for Anthropic's Claude Code CLI. But it's not just another plugin repository. It's an opinionated collection built on a foundation most developers wouldn't expect: samurai philosophy.

Every plugin is organized into one of four categories inspired by Bushido traditions:

Bushido (🎯): Core principles and foundational quality skills. These are the non-negotiables: proof-of-work verification, code review standards, SOLID principles, and TDD practices.

Dō (🛤️): Specialized agents for development disciplines. Pre-configured workflows for NextJS development, CI pipeline optimization, and frontend engineering that understand how all the pieces fit together.

Buki (⚔️): Language and tool skills with validation hooks. TypeScript patterns, React performance optimization, Next.js routing, Biome configuration. The technical skills that separate working code from production-ready code.

Sensei (👴): MCP servers providing external knowledge and integrations. Context7 for up-to-date documentation, ensuring you're always working with current best practices.

Why We Built It

When we talk about shipping 20,000 lines of production code or running development threads in parallel, we're not exaggerating. But that speed only works because we've built systems and practices that prevent the typical AI coding disasters.

We needed a way to codify those practices. To make them repeatable. To share them with the teams we work with.

Han is that system.

The Philosophy: Shu-Ha-Ri

Han structures learning through the traditional Shu-Ha-Ri framework:

Shu (守): Learn the fundamentals. Follow established patterns without deviation.

Ha (破): Understand when and why to break the rules. Adapt patterns to context.

Ri (離): Transcend the rules entirely. Create new patterns based on deep understanding.

This isn't philosophical window dressing. It's a practical framework for growing from competent to excellent.

Quality Over Quantity

We could have built a marketplace with thousands of plugins. We didn't.

Every plugin in Han is:

• Battle-tested in production environments
• Built on proven engineering principles
• Designed to work together, not compete
• Maintained and updated by practitioners

This is the same standard we apply to code: if it doesn't make things meaningfully better, it doesn't belong.

How It Works

Installation is straightforward:

npx @thebushidocollective/han install

Choose your scope (user-wide, project-specific, or local), select the plugins you need, and start working. No configuration hell. No feature bloat. Just tools that make you better at your craft.

Why This Matters Now

AI coding tools are everywhere. But tools are only as good as the practices they enable.

You can use Claude Code to generate thousands of lines of code. The question is: will those lines survive contact with production? With real users? With the next engineer who has to maintain them?

Han doesn't just help you code faster. It helps you code better. It embeds the same disciplines that let us ship quickly without sacrificing quality.

The Seven Bushido Virtues in Code

Han is built on the foundation of the seven Bushido virtues, translated for software engineering:

• Rectitude: Write honest code that does what it claims
• Courage: Delete code that doesn't serve the purpose
• Benevolence: Build systems that serve future maintainers
• Respect: Honor the craft with quality work
• Honesty: Document what the code actually does
• Honor: Take responsibility for what ships
• Loyalty: Commit to excellence, not shortcuts

These aren't abstract ideals. They're practical guidelines that prevent the technical debt, security vulnerabilities, and architectural disasters we're constantly called in to fix.

Who This is For

Han is for engineering teams who understand that speed without quality is just expensive failure. Teams who want to leverage AI without creating maintenance nightmares. Teams who value mastery over mediocrity.

If you're looking for shortcuts, this isn't your tool.

If you're looking to master your craft through disciplined practice, quality craftsmanship, and continuous improvement, Han was built for you.

Open Source, Open Access

Han is MIT licensed and maintained by The Bushido Collective. We built it for ourselves first, then realized others might benefit from the same disciplines that let us work the way we do.

Visit han.guru to explore the marketplace, learn about the philosophy, and install the plugins that fit your practice.

The Bottom Line

Everyone has access to AI coding tools. The winners will be those who use them with discipline.

Vibe coders generate code. Master craftspeople generate systems that scale.

Han helps you become the latter.
