Delegate full API engineering to AI agents that design REST/GraphQL architectures with best practices for versioning and error handling, generate and validate OpenAPI specs and schemas including contract testing with Pact, and configure gateways like AWS API Gateway or Kong for rate limiting, OAuth/JWT auth, routing, and caching.
npx claudepluginhub thebushidocollective/hanSpecialized API contract engineer with expertise in OpenAPI, GraphQL schema design, and contract testing. Use when defining API contracts, implementing schema validation, or setting up contract testing.
Specialized API designer with expertise in API architecture, contract design, and API evolution strategies. Use when designing APIs, creating API contracts, or planning API versioning.
Specialized API gateway engineer with expertise in rate limiting, authentication, request/response transformation, and routing. Use when implementing API gateway patterns or managing API traffic control.
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:

Commands for designing and documenting REST and GraphQL APIs
API design, documentation, and testing with OpenAPI spec generation
Use this agent when you need to design and implement internal API architecture, developer experience, and API infrastructure for B2B applications. This agent specializes in REST API design, GraphQL implementation, API documentation, SDK development, and developer portal creation. Handles API performance optimization, versioning strategies, and internal service communication. Examples:
