What it does
This is a Japanese-language reference guide that teaches an AI agent common server-side coding patterns. Once installed, when you ask for help building a backend, the agent follows conventions such as RESTful URL design, the repository and service layers, auth middleware that checks bearer tokens, selecting only needed database columns, avoiding N+1 queries, Redis caching with expiry, and centralized error handling. The examples use Supabase, Redis and Next.js, so the agent will lean toward those tools.
Great for
- Developers building Node.js, Express or Next.js API backends who read Japanese
- Teams wanting a consistent starting point for API structure, caching and error handling
- Developers using Supabase or Redis who want ready-made examples
Skip it if
- Projects using other languages or frameworks, where the patterns will not directly apply
- Production security decisions: the auth and error examples are illustrative and the file does not cover token validation details, rate limiting or input sanitisation in depth
- Non-developers, since the content assumes coding knowledge
Try asking
- “Design REST endpoints for a marketplace app with filtering and pagination”
- “Refactor my Next.js API route to use a repository and service layer”
- “Add Redis caching with invalidation to my product lookup”
- “Review my database queries for N+1 problems”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Ask the agent to adapt the examples to your own ORM or database rather than copying Supabase code directly
- Verify auth, error and retry code against your security requirements before deploying
- The file is in Japanese; request English output if your team reads English
