バックエンドコード規約とパターン集。APIルート、Repository、バリデーション等の実装パターン。 使用タイミング: (1) 新しいAPIルート作成時 (2) Repository実装時 (3) バリデーション設計時 (4) エラーハンドリング実装時 (5) バックエンドのベストプラクティス確認時。 トリガー例: 「APIルートを作って」「Repositoryパターンで」「バックエンドのパターン」 「Zodでバリデーション」「エラーハンドリングのパターン」
System architecture design for Rust/WebAssembly projects. Creates ADRs, designs APIs, plans module structures, and documents architectural decisions. Never writes implementation code - focuses purely on design and documentation.
Critical guardrail for Supabase database operations ensuring multi-tenant isolation with publication_id filtering, proper use of supabaseAdmin, avoiding SELECT *, error handling patterns, and secure server-side database access. Use when writing database queries, working with supabase, accessing newsletter_campaigns, articles, rss_posts, or any tenant-scoped data.
Defensive programming patterns in Go including interface verification, slice/map copying at boundaries, time handling, avoiding globals, and defer for cleanup. Use when writing robust, production-quality Go code.
Apply when defining service.json routes, choosing public vs segment vs private URL prefixes for VTEX IO services, or setting HTTP cache headers that interact with the VTEX edge and CDN. Covers path patterns, cookie visibility, edge caching behavior, and aligning Cache-Control with data sensitivity. Use for Node or .NET IO backends where request path and response headers determine CDN safety.
Apply when deciding where and how a VTEX IO app should store and read data. Covers when to use app settings, configuration apps, Master Data, VBase, VTEX core APIs, or external stores, and how to avoid duplicating sources of truth or abusing configuration stores for operational data. Use for new data flows, caching decisions, refactors, or reviewing suspicious storage and access patterns in VTEX IO apps.
Apply when designing or implementing HTTP endpoints exposed by a VTEX IO backend service. Covers route boundaries, handler structure, middleware composition, request validation, and response modeling for service.json routes. Use for webhook endpoints, partner integrations, callback APIs, or reviewing VTEX IO handlers that should expose explicit HTTP contracts.
Apply when deciding whether and how VTEX IO apps should use Master Data v2 for custom data. Covers entity boundaries, schema lifecycle, indexing strategy, and when Master Data is the right storage mechanism versus another data approach. Use for reviews, wishlists, forms, or other custom data modeling decisions in VTEX IO apps.
Apply when improving VTEX IO Node or .NET services for latency, throughput, and resilience: in-process LRU, VBase, stale-while-revalidate, AppSettings loading, request context, parallel client calls, and avoiding duplicate work. Covers application-level performance patterns that complement edge/CDN caching. Use when optimizing backends beyond route-level Cache-Control.
C++ library for reducing tail latency in RAM reads by hedging across multiple DRAM channels with uncorrelated refresh schedules
ADO.NET patterns, Entity Framework, database best practices
