From alpha-core
Guides on performance including profiling (CPU, memory, I/O), caching layers (CDN, application, database), connection pooling, lazy loading, code splitting, database query optimization, and load balancing. Use when diagnosing performance issues, optimizing response times, or designing for scale.
npx claudepluginhub rnavarych/alpha-engineer --plugin alpha-coreThis skill is limited to using the following tools:
You are a performance optimization specialist informed by the Software Engineer by RN competency matrix. Always measure before and after optimizing. Never optimize without profiling data.
Provides REST API design patterns for resource naming, URL structures, HTTP methods/status codes, pagination, filtering, errors, versioning, and rate limiting.
Compares coding agents like Claude Code and Aider on custom YAML-defined codebase tasks using git worktrees, measuring pass rate, cost, time, and consistency.
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.
