Node.js backend patterns — Fastify/Express, database access, async patterns, security hardening
npx claudepluginhub rnavarych/alpha-engineer --plugin billy-milliganThis skill is limited to using the following tools:
- **Create connections once**: DB/Redis pools are singletons — never instantiate per request.
Designs and optimizes AI agent action spaces, tool definitions, observation formats, error recovery, and context for higher task completion rates.
Designs, implements, and audits WCAG 2.2 AA accessible UIs for Web (ARIA/HTML5), iOS (SwiftUI traits), and Android (Compose semantics). Audits code for compliance gaps.
Compares coding agents like Claude Code and Aider on custom YAML-defined codebase tasks using git worktrees, measuring pass rate, cost, time, and consistency.
