Rulesrules, skills & MCP servers

Cursor rules for idiomatic Go API development — net/http with chi router, structured logging with slog, error handling patterns, context propagation, database/sql with pgx, and the project layout that the Go community actually uses (not the 'standard' layout that isn't standard).

🎭 211 个即插即用的 AI 专家角色 — 支持 Hermes Agent/Claude Code/Cursor/Copilot 等 16 种工具，覆盖工程/设计/营销/金融等 18 个部门。含 46 个中国市场原创智能体（小红书/抖音/微信/飞书/钉钉等）

18 opinionated Cursor rules for production Next.js 16 apps. Covers `use cache` directive with cacheLife/cacheTag, Partial Prerendering (PPR), middleware stacking for auth + i18n + rate limiting, Server Actions with optimistic updates, ISR revalidation strategies, error boundary patterns, Turbopack config, and a pre-deploy checklist. Not generic advice — specific patterns with code.

Cursor rules for Axum 0.8+ web APIs — extractors, state management, Tower middleware, error handling with thiserror, SQLx queries, and the ownership patterns that LLMs consistently get wrong. Includes tracing setup and graceful shutdown.

12 extremely opinionated Cursor rules that enforce zero-tolerance TypeScript. No `any` (ever), strict null checks, exhaustive switch statements, branded types for IDs, const assertions, discriminated unions for state machines, and proper error types. Every rule includes a BAD example and a GOOD example. For developers who are tired of `as any` and `// @ts-ignore`.

Cursor rules for Rails 8 — Solid Queue (default job backend), Solid Cache, Kamal 2 deployment, Hotwire (Turbo + Stimulus), Authentication generator, and the Rails conventions LLMs break by writing controller logic in views.

Cursor rules for Django 5.1+ with Django REST Framework — fat models with custom managers, lean views, serializer patterns, queryset optimization (select_related/prefetch_related), Celery task patterns, and the security settings LLMs always forget.

Opinionated Cursor rules for Next.js 16 — Cache Components with 'use cache', Partial Prerendering (PPR), the new proxy middleware (renamed from middleware.ts), async params/searchParams, and cacheLife/cacheTag patterns. Targets the actual breaking changes, not rehashed docs.

Cursor rules for FastAPI 0.115+ with Pydantic v2 — dependency injection patterns, async/sync router decisions, response models, error handling, middleware, background tasks, and the SQLAlchemy async session pattern that actually works in production.

Cursor rules for Swift 6 and SwiftUI — the Observation framework (@Observable, not ObservableObject), SwiftData (not Core Data), structured concurrency, NavigationStack patterns, and strict concurrency checking that Swift 6 enforces.

15 Cursor rules (.mdc files) optimized for minimal token consumption while maintaining full behavioral control. Every rule includes a measured token cost annotation, and most are under 100 tokens. The set includes before/after comparisons showing how typical verbose rules waste tokens on examples the model already knows. Covers: code style, error handling, testing, TypeScript, React, API design, git workflow, security, and accessibility. Designed for developers on Cursor Pro who hit usage limits, or anyone who wants more context window for their actual code.

Agentic-first Cursor Rules powered by MiniMax M2 — clarify-first prompting, interleaved thinking, and full tool orchestration for production-ready AI coding

Cursor rules for using shadcn/ui the way its own maintainers describe it: copy-paste source code you own, Radix primitives underneath, CSS variables for theming, Tailwind utilities via cn(). Covers the Tailwind v4 / OKLCH / @theme-inline migration, the cn() + twMerge contract, the wrap-nothing composition rule, the Form + react-hook-form + Zod triad, and the update-sync problem that happens when you customize too aggressively. Based on canonical patterns from ui.shadcn.com plus real bugs in github.com/shadcn-ui/ui issues #6427, #6585, #6856, #10101, and Hacker News discussions on the copy-paste model.

Production-grade Cursor rules used by senior engineers at top tech companies. Covers architecture decisions, code review standards, testing strategies, and security best practices. Battle-tested across 50+ production codebases.

Cursor rules for implementing Stripe Checkout in a Next.js App Router project. Every rule addresses a real, documented gotcha: raw-body handling in route handlers, signature verification, idempotency against the 3-day retry schedule, the `checkout.session.completed` vs `invoice.paid` race, and the middleware body-parser trap. Based on the canonical stripe-node/nextjs example plus six issues filed against vercel/next.js and vercel/nextjs-subscription-payments.

25 battle-tested refactoring patterns encoded as Cursor rules. Automatically suggests extract method, replace conditional with polymorphism, introduce parameter object, and more.
