    Mckay’s App Template

    Mckay’s App Template

    This is the template I use to start new full-stack projects

    ...The template includes a frontend built with Next.js, Tailwind CSS, and often UI components/frameworks like Shadcn + Framer Motion; a backend stack using PostgreSQL, Supabase, and Drizzle ORM for database operations; authentication via Clerk; and optional payment integration using Stripe. By providing a ready-to-go configuration (with example folder structure, database setup, auth, payment hooks, and environment templates), it lets developers skip the tedious initial setup and get straight to building product features. The template is ideal for startups, prototypes, or side-projects where you want a robust, production-grade starting point — with user accounts, auth, DB, and payments already wired up.

    multi-agent-shogun

    Samurai-inspired multi-agent system for Claude Code

    multi-agent-shogun is a multi-agent orchestration system designed to coordinate multiple AI coding agents working in parallel. Inspired by the hierarchy of a feudal Japanese military structure, the system organizes agents into roles such as Shogun, Karo, and Ashigaru, which correspond to strategist, coordinator, and worker agents. A user interacts primarily with the Shogun agent by issuing natural language instructions that describe the desired tasks. The system then automatically distributes work among multiple worker agents, allowing tasks to run simultaneously rather than sequentially. ...

    KSP

    KSP

    Kotlin Symbol Processing API

    KSP is Kotlin’s lightweight, idiomatic alternative to Java annotation processing that gives compile-time access to Kotlin program structure. Rather than forcing Kotlin through Java’s annotation APIs, it exposes Kotlin-first symbols—classes, functions, properties, types—so processors can generate code efficiently. The design dramatically reduces incremental build overhead by operating directly on symbols without compiling stubs, which speeds up large multi-module projects.
