description: Design and implement RESTful APIs, GraphQL endpoints, and backend API architecture following modern standards. Use this skill when creating or modifying API endpoints, route handlers, controllers, API middleware, authentication/authorization logic, or any files that define HTTP endpoints such as routes.py, api.js, controllers/, endpoints/, or API specification files (OpenAPI/Swagger). Apply this skill when implementing API versioning, rate limiting, request/response handling, API documentation, or when working with API gateway configurations. This skill is essential for building scalable, secure, and well-documented APIs that follow RESTful principles, handle errors gracefully, and provide consistent developer experiences across microservices and serverless architectures.

# Backend API
This Skill provides Claude Code with specific guidance on how to adhere to coding standards as they relate to how it should handle backend API.
## When to use this skill
- When creating or modifying REST API endpoints, routes, or controllers
- When implementing GraphQL schemas, resolvers, or queries
- When working on API middleware, authentication, or authorization logic
- When designing API request/response structures and data serialization
- When implementing API versioning strategies (URL path or header-based)
- When adding rate limiting, throttling, or API security features
- When writing API documentation (OpenAPI/Swagger specifications)
- When working with files like `routes.py`, `api.js`, `controllers/`, `endpoints/`, or API gateway configs
- When implementing error handling and consistent HTTP status codes for APIs
- When building microservices communication patterns or serverless API functions
- When adding pagination, filtering, sorting, or search capabilities to API endpoints
- When implementing async APIs, webhooks, or event-driven API patterns

Use this skill when developing or maintaining browser extension code in the `browser/` directory, including Chrome/Firefox/Edge compatibility, content scripts, background scripts, or i18n updates.
SEO optimization with keyword analysis, readability assessment, technical validation, content quality. Use for search rankings, blog posts, content audits, or encountering keyword density, readability scores, meta tags, schema markup errors.
Python backend development expertise for FastAPI, security patterns, database operations, Upstash integrations, and code quality. Use when: (1) Building REST APIs with FastAPI, (2) Implementing JWT/OAuth2 authentication, (3) Setting up SQLAlchemy/async databases, (4) Integrating Redis/Upstash caching, (5) Refactoring AI-generated Python code (deslopification), (6) Designing API patterns, or (7) Optimizing backend performance.
Drive the full internationalization journey for a project — detect the stack, recommend a library, set up the chosen library, wrap existing strings, and optionally connect a translation platform. Use when the user asks to add or configure i18n, internationalization, localization, multi-language support, or translations — including when they explicitly mention LinguiJS, Lingui, next-intl, "wrap strings", "find hardcoded text", "make my app translatable", or "set up translations".
