Review Mosoo changes for project-rule, architecture, type-safety, data-scope, generated-source, observability, dependency, and verification violations. Use before committing, after completing a feature, or when reviewing another agent's diff, especially for API, GraphQL, D1, runtime, auth, UI, or infrastructure changes.

Avoid unnecessary React effects in Mosoo while using React useEffect directly for real external synchronization. Use when writing or reviewing React components, refactoring effect-driven derived state or event relays, handling subscriptions and browser APIs, or validating web changes with Mosoo's focused Justfile commands.

Build or review Cloudflare Sandbox SDK integrations using repository evidence and current official documentation. Use for secure code execution, agent runtimes, container-backed tools, Wrangler bindings, Dockerfiles, preview services, or Sandbox lifecycle work, especially in an existing project whose package manager, Wrangler format, and image versions must be preserved.

Better Auth server/client setup: `auth.ts`, generated schema, DB adapters, sessions, cookies, env vars, and plugins. Use when mentioning Better Auth, betterauth, auth handlers, OAuth, email/password, or session configuration.

Scaffold Better Auth in TypeScript apps: framework handlers, DB adapters, OAuth, email/password, and auth UI. Use when adding login, sign-up, session handling, or Better Auth plugins.

Better Auth email/password setup: verification emails, password reset, policies, hashing, and credential sign-in. Use when adding or hardening email/password login, sign-up, reset, or verification flows.

Readability-first TypeScript and TSX style guardrails for strict codebases. Use when reviewing or editing TypeScript, defining shared contracts, creating lintable style rules, or deciding between type vs interface, null vs undefined, and Pick/Omit/Partial-heavy type expressions.
