Summary

A comprehensive Rails optimization guide with 45 rules across database queries, controllers, security, caching, and background jobs. Reach for this when you're writing ActiveRecord queries, building API endpoints, or reviewing code for N+1s and performance issues. The priority system is smart: database and controller patterns are marked critical, while background job patterns sit lower since they affect fewer requests. Each rule links to detailed references with examples, though the real value is having eager loading, indexing, and strong params checks baked into your workflow. It's opinionated about service objects and query objects for complex logic, which keeps models from turning into thousand-line monsters.

nestjs-modular-monolith

tech-leads-club/agent-skills

Specialist in designing and implementing scalable modular monolith architectures using NestJS with DDD, Clean Architecture, and CQRS patterns. Use when building modular monolith backends, designing bounded contexts, creating domain modules, implementing event-driven module communication, or when user mentions "modular monolith", "bounded contexts", "module boundaries", "DDD", "CQRS", "clean architecture NestJS", or "monolith to microservices". Do NOT use for simple CRUD APIs, frontend work, general NestJS questions without architectural context, or stack-agnostic evolutionary modular monolith design (use evolutionary-modular-architecture).

simple-deck

nexu-io/open-design

Single-file horizontal-swipe HTML deck. Built by copying the seed `assets/template.html` (which carries the proven 5-rule iframe nav script) and pasting slide layouts from `references/layouts.md`. Pitch decks, product overviews, study material — when you don't need the magazine aesthetic of `magazine-web-ppt`.

sprite-animation

nexu-io/open-design

A pixel / sprite-style animated explainer slide — full-bleed cream stage, bold display year, animated pixel-art mascot (e.g. Hanafuda card, mushroom, or 8-bit console), kinetic Japanese display type, ticking timeline ribbon. Reads like a single frame of an educational motion video — looping CSS keyframes, no JS, ready to be screen-recorded into a vertical video. Use when the brief asks for a "sprite animation", "pixel-art video", "8-bit explainer", "history of X explainer", "kinetic typography history", "Nintendo-style", "精灵图动画", "像素动画", or "复古动画".
