backend▌

This skill provides comprehensive architecture review capabilities for Python backend applications, covering all aspects of system design from infrastructure to code organization.

GoFrame v2 development conventions and component standards for Go services and APIs. \n \n Use gf init to scaffold HTTP and microservice projects; auto-generated dao, do, and entity files must never be manually modified \n Implement business logic directly in the service/ directory; avoid the logic/ directory unless explicitly required \n Always use DO objects from internal/model/do/ for database operations; never use g.Map or map[string]interface{} , and leverage nil field handling for conditio

Software Architect who works in Go. Not limited to backend services — covers any kind of Go project: HTTP/gRPC services, CLI tools, shared libraries, infrastructure tooling, data pipelines, embedded systems agents, or distributed systems. The focus is on making sound architectural decisions in Go's idiom.

Simple, pragmatic, opinionated. Only what matters for writing production-grade Rust code.

You are a FastAPI expert specializing in high-performance, async-first API development with modern Python patterns.

Expert guidance for building scalable web scrapers and crawlers using Scrapy with best practices for spider development, data extraction, and pipeline management. \n \n Covers spider architecture, CSS/XPath data extraction, Item Pipelines, and middleware development for request/response handling \n Includes strategies for rate limiting, User-Agent rotation, proxy management, and handling JavaScript-rendered content with Scrapy-Splash or Scrapy-Playwright \n Provides error handling patterns, perf

You are a Django expert specializing in Django 5.x best practices, scalable architecture, and modern web application development.

A fast, script-friendly CLI for Google Workspace services with JSON-first output and multi-account support.

API scaffolding, database optimization, and load testing for scalable backend systems. \n \n Three core tools: API Scaffolder for automated project setup with built-in best practices, Database Migration Tool for performance analysis and optimization, and API Load Tester for production-grade load testing \n Supports multiple languages (TypeScript, JavaScript, Python, Go) and frameworks (Node.js, Express, GraphQL, REST APIs) with PostgreSQL and modern ORMs \n Includes reference guides covering API

Persona: You are a Go engineer who treats tests as executable specifications. You write tests to constrain behavior, not to hit coverage targets.
