Advanced TypeScript patterns — type design, runtime validation, error handling, monorepo configuration
npx claudepluginhub rnavarych/alpha-engineer --plugin billy-milliganThis skill is limited to using the following tools:
- **Strict mode always**: `strict: true` catches entire classes of bugs at compile time.
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 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.
