1. Software Development

Automates i18n consistency checks, identifying missing translation keys and hardcoded strings in code.

Executes tests, analyzes coverage, and debugs failures to ensure code quality and reliability in software development.

Guides test-driven development for Tetris game logic, triggering on test-related phrases and emphasizing Result<T,E> pattern and property-based testing with fast-check.

Automates Ruff setup and execution for Python projects, including installation, configuration, and linting/formatting commands.

Initializes Python projects with uv, handling setup tasks such as generating project files, configuring dependencies in pyproject.toml, and verifying uv installation across platforms.

Executes individual development tasks following Test-Driven Development (TDD) methodology, ensuring systematic implementation and testing from specifications.

Provides in-depth exploration of codebase structure, architecture, and key components at the start of a development session.

Verifies code against Tetris architecture standards, checking prohibited patterns and required design patterns during reviews and refactoring.

Provides read-only exploration of codebases to map architecture, identify patterns, and generate documentation for unfamiliar code.

Manages Python project dependencies and workflows using the uv package manager, covering best practices and common patterns.

Enables developers to write tests before implementation code, ensuring robust and maintainable software through iterative development cycles.

Designs React components using Tetris architecture for consolidation, unified patterns, and efficient hook usage in creation and optimization.

Designs and implements RESTful API endpoints with resource-based URLs, HTTP methods, and proper request/response handling, including versioning and rate limiting.

Assists developers in processing and evaluating code review feedback and pull request comments with technical verification before implementation.

Enforces TypeScript strict mode and type safety in Tetris codebase, focusing on error handling and avoiding type assertions.

Manages database schema evolution through version-controlled, reversible migrations with zero-downtime deployment capabilities for backend systems.

Provides testing utilities for FastAPI endpoints, dependency mocking, and TestClient integration for API validation.

Executes software implementation plans using independent subagents within a single development session.

Automates semantic versioning (semver) for releases, ensuring package.json and pyproject.toml versions match git tags.

Manages and maintains a project's technical stack, ensuring consistency in frameworks, languages, databases, and tools across all development activities.

Provides secure and optimized database query implementation using parameterized statements, eager loading, and indexing to prevent SQL injection and N+1 issues.

Enforces consistent code style across all programming languages by applying naming conventions, formatting standards, and DRY principles to enhance readability and maintainability.

Defines database models with proper structure, relationships, constraints, and validation for ORM and database schema implementation.

Provides mandatory development guidelines for Flutter apps, covering UI/UX design, state management, networking, API integration, and required workflows.
