ネットワーク通信・データ永続化ガイド。API通信、HTTP/WebSocket、データキャッシュ、Core Data、Realm、UserDefaults、Keychain等、iOS開発におけるデータ取得・保存の実践的なパターン。

Guides editing and creation of OpenAPI 3.0 contracts in binora-contract submodule with modular YAML structure, Redocly validation, and Django/DRF consistency checks. Auto-activates when editing contracts, implementing endpoints, or modifying serializers.

API 開發流程引導技能，協助開發者選擇合適的開發流程（API First 或 Code First），並提供 OpenAPI 規格管理、程式碼產生等自動化支援。

Generate morphism implementations from build artifacts. Creates domain operationsusing App monad, API handlers (via F_api), and compositions. All effectfuloperations return App[A]. Use when: implementing operations, creating endpoints.

Expert knowledge on Next.js API route patterns, authentication with getAuthOrTest, error handling, response formats, rate limiting, and webhook verification. Use this skill when user asks about "create api endpoint", "api route", "error handling", "authentication", "next.js api", or "route handler".

Comprehensive documentation specialist covering API documentation, technical writing, design documentation, migration guides, and changelog generation. Use when creating OpenAPI/Swagger specs, generating SDKs, writing user guides, creating README files, documenting architecture, writing design specs, creating ADRs, writing migration guides, or generating changelogs from git commits. Handles versioning, examples, developer experience, and user-facing documentation.

Validates Django REST Framework endpoints against OpenAPI specification. This skill should be used when implementing or modifying API endpoints to ensure request/response schemas, status codes, authentication, and parameters match the contract specification.

Provides REST API design and implementation standards. Ensures proper URL structure, pagination, sorting, filtering, and error handling patterns. Specializes in RESTful principles, HTTP method semantics, status code usage, versioning strategies, HATEOAS, and API documentation. Implements consistent response structures and content negotiation.Use when: designing REST API endpoints, defining URL structures and naming conventions, implementing pagination/sorting/filtering, choosing appropriate HTTP methods (GET/POST/PUT/PATCH/DELETE), selecting HTTP status codes, designing request/response schemas, handling API errors and validation, implementing API versioning, documenting APIs with OpenAPI/Swagger, or designing hypermedia controls (HATEOAS).

PHP API development mastery - REST, GraphQL, JWT/OAuth, OpenAPI documentation

Build resilient data ingestion pipelines from APIs. Use when creating scripts that fetch paginated data from external APIs (Twitter, exchanges, any REST API) and need to track progress, avoid duplicates, handle rate limits, and support both incremental updates and historical backfills. Triggers: 'ingest data from API', 'pull tweets', 'fetch historical data', 'sync from X', 'build a data pipeline', 'fetch without re-downloading', 'resume the download', 'backfill older data'. NOT for: simple one-shot API calls, websocket/streaming connections, file downloads, or APIs without pagination.

Use when documentation drift is detected. Comprehensively audits codebase and creates/updates Swagger, features docs, and general documentation to achieve full sync.

Generate TypeScript API client from Swagger/Go comments. Use when updating API endpoints, adding new routes, or regenerating the frontend API client after backend changes.

Library of battle-tested security prompt templates for secure feature implementation. Use when implementing forms, endpoints, authentication, authorization, file uploads, or conducting security reviews. Triggers include "security prompt", "secure form", "RBAC", "threat model", "STRIDE", "admin endpoint", "file upload", "security testing", "code review", "OWASP".

Debug WebSocket connection issues between CLI and FigJam plugin. Use when diagrams aren't syncing or connection fails.

基于 gin-gonic/gin 的企业级 Web 框架增强版，提供开箱即用的 JWT 认证、SSE 实时通信、缓存管理、OpenAPI 文档生成等企业级功能。涵盖选项式路由配置、统一响应格式、中间件管理、安全加固、性能优化等完整开发能力。

Expert in API integration with React Query, SWR, RTK Query, REST/GraphQL clients, WebSocket real-time, optimistic updates, caching strategies, and error handling

Create custom API endpoints and whitelisted methods for Frappe applications. Use when building REST APIs or custom endpoints.

Apply when designing RESTful APIs, defining endpoints, HTTP methods, status codes, and response formats.

Master API documentation with REST references, OpenAPI specs, code examples, and developer-friendly API guides.

Generate API documentation, user guides, and technical documentation for Frappe apps. Use when documenting APIs, creating user guides, or generating OpenAPI specs.
