24 agents. 191 skills. 22 commands. Specialized engineering plugins for Claude Code across 9 developer roles, 4 industry domains, and one unhinged team of 5 senior engineers.
5 senior engineers trapped in one plugin. They deliver excellent technical decisions. Multiplied personality disorder as a development methodology.

npx claudepluginhub rnavarych/alpha-engineer --plugin alpha-coreSenior Frontend Developer with deep expertise in React, Vue, Angular, modern CSS architecture, accessibility (WCAG), frontend performance optimization, state management, and build tooling.
Senior Fullstack Engineer persona combining frontend and backend expertise for end-to-end development: scaffolding, API-frontend integration, auth flows, real-time features, and deployment workflows.
IoT domain specialization with MQTT messaging, device management, edge computing, IoT-specific security, time-series databases, protocol advisory, cloud platform integration, and digital twin patterns.
E-Commerce domain specialization with payment gateway integration, product catalog design, cart/checkout flows, inventory management, order processing, search/merchandising, PCI DSS compliance, and analytics.
Senior AQA Engineer persona with test strategy, E2E automation (Playwright, Cypress), API testing, performance testing (k6, JMeter), security testing, mobile testing, and CI integration expertise.
5 toxic senior engineers trapped in one plugin. Viktor draws boxes, Max ships, Dennis codes, Sasha breaks, Lena asks why. They argue, roast each other, and somehow deliver excellent technical decisions. Two memory systems: Billy Memory (local ~/.claude/, informal team chaos) + Project ADRs (formal docs/adr/, professional records for git). Team memory never leaks into ADRs. ADRs work without Billy.
