API Development

This skill provides comprehensive guidance for documenting SAP APIs following official SAP API Style Guide standards. It should be used when creating or reviewing API documentation for REST, OData, Java, JavaScript, .NET, or C/C++ APIs. The skill covers naming conventions, documentation comments, OpenAPI specifications, quality checklists, deprecation policies, and manual documentation templates. It ensures consistency with SAP API Business Hub standards and industry best practices. Keywords: SAP API, REST, OData, OpenAPI, Swagger, Javadoc, JSDoc, XML documentation, API Business Hub, API naming, API deprecation, x-sap-stateInfo, Entity Data Model, EDM, documentation tags, API quality, API templates

Comprehensive ABAP development skill for SAP systems. Use when writing ABAP code, working with internal tables, structures, ABAP SQL, object-oriented programming, RAP (RESTful Application Programming Model), CDS views, EML statements, ABAP Cloud development, string processing, dynamic programming, RTTI/RTTC, field symbols, data references, exception handling, or ABAP unit testing. Covers both classic ABAP and modern ABAP for Cloud Development patterns.

Generate OpenAPI/REST endpoints from tRPC routers. Use when you have a tRPC API but need to expose REST endpoints for third-party integrations, mobile apps, or public API documentation. Provides automatic Swagger UI and OpenAPI spec generation. Choose this when you want type-safe internal APIs (tRPC) with REST fallback for external consumers.

WebSocket real-time updates, SSE broadcasting, event buffering

Generate API specification documentation from codebase analysis. Detects REST endpoints, function signatures, type definitions, and schemas. Triggers: API specification, endpoints, REST API, type definitions, OpenAPI, Swagger, API documentation.

Real-time bidirectional communication with security focus on CSWSH prevention, authentication, and message validation

Generate and validate Python clients from OpenAPI specs. Use for generation, validation, or troubleshooting.

Create Next.js 16 API Route Handlers. Use when building REST endpoints (GET, POST, PUT, DELETE), implementing CRUD operations, or creating authenticated APIs with Zod validation.

Quick reference for RESTful API design patterns, HTTP semantics, caching, and rate limiting. Triggers on: rest api, http methods, status codes, api design, endpoint design, api versioning, rate limiting, caching headers.

FastAPI web framework patterns. Triggers on: fastapi, api endpoint, dependency injection, pydantic model, openapi, swagger, starlette, async api, rest api, uvicorn.

Generates OpenAPI/Swagger/GraphQL documentation and SDKs from code

Unifies API response patterns across endpoints including pagination format, error structure, status codes, response envelopes, and versioning strategy. Provides contract documentation, shared TypeScript types, middleware utilities, and migration plan. Use when standardizing "API contracts", "response formats", "API conventions", or "API consistency".

This skill automates API endpoint testing, including request generation, validation, and comprehensive test coverage for REST and GraphQL APIs. It is used when the user requests API testing, contract testing, or validation against OpenAPI specifications. The skill analyzes API endpoints and generates test suites covering CRUD operations, authentication flows, and security aspects. It also validates response status codes, headers, and body structure. Use this skill when the user mentions "API testing", "REST API tests", "GraphQL API tests", "contract tests", or "OpenAPI validation".

Use when analyzing and improving performance for database queries, API endpoints, or frontend rendering.

JSON Schema仕様に基づくスキーマ設計を専門とするスキル。API仕様の定義、OpenAPI連携、バリデーションルールの標準化を通じて、相互運用性の高いデータ構造を設計します。Anchors:• Effective TypeScript (Dan Vanderkam) / 適用: 型安全性とスキーマ設計 / 目的: 堅牢なスキーマ構造の実現• JSON Schema仕様 (Draft 2020-12) / 適用: 標準スキーマ定義 / 目的: 言語非依存なデータバリデーションTrigger:JSONスキーマ定義、APIレスポンス検証、データバリデーション設計、OpenAPI統合、スキーマ継承パターン、複雑なデータ構造の妥当性確認時に使用。

This skill enables Claude to track and optimize application response times. It uses the response-time-tracker plugin to monitor API endpoints, database queries, external service calls, frontend rendering, and background job execution. The plugin calculates P50, P95, and P99 percentiles, average and maximum response times. Use this skill when you need to identify performance bottlenecks, monitor SLOs, or receive alerts about performance degradation. Trigger this skill with phrases like "track response times", "optimize latency", or "monitor application performance".
