backend-development
Delegate backend architecture and API design to specialized AI agents: craft REST/GraphQL contracts with versioning and evolvability reviews, design data models, scalable systems, pipelines, ETL/ELT flows, and event-driven patterns.
What's Inside
Agents2
api-designer
/api-designer
Use 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>
backend-architect
/backend-architect
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>
README
Han
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.
Getting Started
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.
Alternative Installation
# Homebrew (macOS/Linux)
brew install thebushidocollective/tap/han
How It Works
- Install - One command installs the CLI and auto-detects plugins for your stack
- Code - Claude writes code as usual. No workflow changes needed
- Validate - Stop hooks run automatically. Linters, formatters, type checkers, and tests are all verified
- Learn - Local metrics track success rates and calibrate confidence. Nothing leaves your machine
Plugin Categories
139 plugins across six categories:
| Category | Description | Examples |
|---|---|---|
| Core | Essential infrastructure. Auto-installs han binary, provides metrics and MCP servers | Always required |
| Languages | Validation plugins for your language/runtime | TypeScript, Rust, Python, Go, Ruby |
| Validation | Linters, formatters, and quality tools | Biome, ESLint, ShellCheck, Pytest |
| Disciplines | Specialized AI agents for engineering domains | Security, accessibility, API design, architecture |
| Services | MCP servers for external platforms | GitHub, GitLab, Linear |
| Tools | MCP servers for development utilities | Playwright, Blueprints, Context7 |

Why It Works
- Smart Caching - Only runs validation when relevant files change. Native Rust hashing keeps it fast
- Local Metrics - Tracks task success and confidence calibration. All data stays on your machine
- Zero Config - Binary auto-installs on first session.
--autoflag detects your stack automatically - Any Stack - TypeScript, Python, Rust, Go, Ruby, Elixir. If there's a linter, there's a plugin
CLI Commands
