Lists classes within a Simulabra module, including docstrings, line numbers, and slots for code inspection.

Performs critical code reviews to assess quality, architecture, testing, and production readiness, ensuring robust and reliable code before merging.

Interprets legal text from regelrecht YAML files to generate machine-executable logic with parameters, operations, and cross-law references.

Guides implementation of React 19 patterns, Context shorthand syntax, use() hook, and optimization techniques like useMemo and useCallback.

Manages package dependencies using pnpm and corepack, including installation, upgrades, and troubleshooting via the packageManager field in package.json.

Generates TypeScript types for TMDB API endpoints using Zod schemas via pnpm codegen:tmdb.

Provides React component styling utilities using StyleX with design tokens, breakpoints, and responsive patterns for consistent theming.

Provides internationalization patterns for server and client components using getTranslations and useTranslations for multilingual content handling.

Provides data fetching patterns for server/client components using fetch API, TanStack Query, and related utilities for API calls and data loading.

Interactive workflow for setting up Magnet MCP server locally in magnet-app directory, triggered by user commands like 'local setup'.

Guides developers through Domain-Driven Design (DDD) methodology, emphasizing test-first domain model implementation and structured development flow from in-memory repositories to infrastructure.

Prevents non-conforming code generation by mandating study of existing implementation before new features, refactoring, or code modifications.

Guides domain modeling using DDD principles, including value objects, entities, aggregates, and domain services for effective software design.

Promotes simple, maintainable code by preventing over-engineering during reviews, design, and refactoring.

Guides restructuring disorganized codebases into clear package/module hierarchies, resolving dependency issues and circular references for improved maintainability.

Enforces the 'one public type per file' standard during code generation, preventing multiple public types in a single file.

Assists in designing and reviewing software projects adhering to Clean Architecture principles, emphasizing 4-layer structure and proper layer responsibilities.

Analyzes and refactors codebase package structure, resolving circular dependencies and splitting monolithic modules.
