Claude Skills by DongDuong2001

- [ ] **API Design:** Define RESTful endpoints, path parameters, and query parameters. - [ ] **Data Validation:** Plan Pydantic models for request (In) and response (Out) schemas. - [ ] **Database & ORM:** Select the async DB driver and ORM (e.g., SQLAlchemy 2.0 with async engine, SQLModel). - [ ] **Authentication:** Plan dependency injection for Auth (OAuth2, JWT tokens).

- [ ] **Framework Selection:** Choose web framework (Axum, Actix-web) based on performance vs. ecosystem needs. - [ ] **Crate Ecosystem:** Plan dependencies (e.g., `tokio` for async runtime, `serde` for serialization, `sqlx` or `sea-query` for DB). - [ ] **Error Handling:** Define a centralized application error type using crates like `thiserror` or `anyhow`. - [ ] **State Management:** Plan how application state (DB pools, config) will be shared across thread workers.

- [ ] **Rendering Strategy:** Define which routes will be Server Components (RSC) and which require Client Components (`use client`). - [ ] **Data Fetching:** Plan caching strategies using Next.js 15's native `fetch` overrides and `React.cache`. - [ ] **Routing Tree:** Map out nested layouts, `loading.tsx`, `error.tsx`, and `not-found.tsx` boundaries. - [ ] **Mutations:** Plan Server Actions for data mutations instead of traditional API routes where possible.

- [ ] **Failure Modes & Store Review:** Identify App Store / Play Store review edge cases, account deletion rules, and blocker policies BEFORE polishing the UI. - [ ] **Native Build Config:** Establish EAS Build profiles or Bare RN configs early as they are silent killers. Identify constraints with third-party SDKs. - [ ] **Framework Base:** Decide between Expo Managed Workflow vs. Bare React Native based on native module requirements. - [ ] **Navigation:** Plan navigation structure using React

- [ ] **Protocol Design:** Define contract architecture (e.g., Monolithic vs. Proxy/Upgradable vs. Diamond pattern). - [ ] **Tokenomics:** Map out value flow, minting, burning, and pausing capabilities (ERC20/ERC721/ERC1155). - [ ] **Access Control:** Plan roles (Owner, Admin, Minter) and multisig requirements. - [ ] **Gas Economics:** Architect data structures to minimize storage operations (packing variables).
