Automated frontend, backend, and runtime test creation/execution for RustLearn or similar Rust/Next.js apps: Rust contract tests, API helper tests, route guard tests, Playwright/e2e checks, Docker Compose and Kubernetes smoke/log verification. Use when asked to add, run, debug, or harden repeatable tests.
Implement RustLearn backend/API work in Rust Actix Web with Diesel/PostgreSQL, repository/service layers, permission-scoped authorization, migrations, workers, wallets, reports, and frontend contract endpoints. Use when Codex is asked to add, fix, or refactor backend contracts, handlers, services, repositories, migrations, or Rust tests.
Implement product-grade frontend work for RustLearn or similar Next.js/React apps: app shell, auth/session UI, learner/teacher/organization/admin routes, permission-aware components, forms, data helpers, responsive layout, and UX refactors. Use when Codex is asked to build, refactor, or fix frontend code rather than only plan or test it.
Manual rendered frontend QA for RustLearn or similar web apps through Browser/Playwright: inspect desktop/mobile UI, exercise user flows, verify copy/states/permissions, capture screenshots, and report findings. Use when asked to manually test, QA, inspect, reproduce, or validate frontend user flows.
Frontend product management for RustLearn or similar product work: sequence milestones, update TODO roadmap, define dependencies, cut scope, identify risks, and turn goals into implementation plans. Use when asked to plan, prioritize, break down, roadmap, or coordinate frontend development.
Frontend product ownership for RustLearn or similar product work: define persona value, user stories, acceptance criteria, scope boundaries, and done/not-done decisions. Use when asked to decide what a frontend feature must do for users, write acceptance criteria, or judge whether a flow is acceptable.
