Architect scalable backend systems, design evolvable RESTful and GraphQL APIs with versioning and breaking change analysis, model data structures, and build data pipelines plus analytics infrastructure using specialized AI agents.
npx claudepluginhub thebushidocollective/hanUse this agent when you need to design API contracts, analyze breaking changes, design RESTful or GraphQL APIs, implement versioning strategies, or review API architecture . Examples: <example>Context: User needs to add a new API endpoint for user profiles . user: 'We need an endpoint to update user profile information' assistant: 'I'll use the api-designer agent to design the API contract with proper HTTP semantics and versioning strategy.' <commentary>API contract design requires the api-designer agent's expertise in REST principles and API design.</commentary></example> <example>Context: User wants to evaluate proposed API changes . user: 'Can you review these proposed changes to our user API for breaking changes?' assistant: 'Let me use the api-designer agent to analyze the changes and identify any breaking changes that could impact clients.' <commentary>Breaking change analysis and API evolution requires the api-designer agent.</commentary></example>
Use this agent when you need to design data models, architect backend systems, build data pipelines, implement analytics infrastructure, or design scalable data processing systems . Examples: <example>Context: User needs to design data architecture for analytics dashboard . user: 'We need to track completion rates and performance metrics across our platform' assistant: 'I'll use the backend-architect agent to design the data pipeline and analytics infrastructure for tracking these metrics.' <commentary>Analytics architecture and data pipeline design requires the backend-architect agent's expertise in system design and data modeling.</commentary></example> <example>Context: User wants to implement event-driven architecture . user: 'We need to process user events in real-time for our recommendation system' assistant: 'Let me use the backend-architect agent to design the event-driven architecture and data flow patterns.' <commentary>Event-driven systems and data architecture require the backend-architect agent.</commentary></example>
Ship-ready code from your AI coding agent. 139+ plugins for quality gates, tooling, memory, and specialized agents — so your AI writes code that's ready to merge.
Two commands. That's it.
# 1. Install the CLI
curl -fsSL https://han.guru/install.sh | bash
# 2. Auto-detect and install plugins for your project
han plugin install --auto
Next time you use Claude Code, validation hooks run automatically when you finish a conversation.
# Homebrew (macOS/Linux)
brew install thebushidocollective/tap/han
139 plugins across four categories:
| Category | Description | Examples |
|---|---|---|
| Core | Essential infrastructure. Auto-installs han binary, provides metrics and MCP servers | Always required |
| Jutsu (Tools) | Validation plugins for your stack | TypeScript, Biome, Pytest, RSpec, ShellCheck |
| Dō (Agents) | Specialized AI agents | Code review, debugging, architecture, security |

Use this agent when designing APIs, building server-side logic, implementing databases, or architecting scalable backend systems. This agent specializes in creating robust, secure, and performant backend services. Examples:\n\n<example>\nContext: Designing a new API\nuser: "We need an API for our social sharing feature"\nassistant: "I'll design a RESTful API with proper authentication and rate limiting. Let me use the backend-architect agent to create a scalable backend architecture."\n<commentary>\nAPI design requires careful consideration of security, scalability, and maintainability.\n</commentary>\n</example>\n\n<example>\nContext: Database design and optimization\nuser: "Our queries are getting slow as we scale"\nassistant: "Database performance is critical at scale. I'll use the backend-architect agent to optimize queries and implement proper indexing strategies."\n<commentary>\nDatabase optimization requires deep understanding of query patterns and indexing strategies.\n</commentary>\n</example>\n\n<example>\nContext: Implementing authentication system\nuser: "Add OAuth2 login with Google and GitHub"\nassistant: "I'll implement secure OAuth2 authentication. Let me use the backend-architect agent to ensure proper token handling and security measures."\n<commentary>\nAuthentication systems require careful security considerations and proper implementation.\n</commentary>\n</example>
Comprehensive skill pack with 66 specialized skills for full-stack developers: 12 language experts (Python, TypeScript, Go, Rust, C++, Swift, Kotlin, C#, PHP, Java, SQL, JavaScript), 10 backend frameworks, 6 frontend/mobile, plus infrastructure, DevOps, security, and testing. Features progressive disclosure architecture for 50% faster loading.
Use this agent when you need expert assistance with React Native development tasks including code analysis, component creation, debugging, performance optimization, or architectural decisions. Examples: <example>Context: User is working on a React Native app and needs help with a navigation issue. user: 'My stack navigator isn't working properly when I try to navigate between screens' assistant: 'Let me use the react-native-dev agent to analyze your navigation setup and provide a solution' <commentary>Since this is a React Native specific issue, use the react-native-dev agent to provide expert guidance on navigation problems.</commentary></example> <example>Context: User wants to create a new component that follows the existing app structure. user: 'I need to create a custom button component that matches our app's design system' assistant: 'I'll use the react-native-dev agent to create a button component that aligns with your existing codebase structure and design patterns' <commentary>The user needs React Native component development that should follow existing patterns, so use the react-native-dev agent.</commentary></example>
