Enterprise-grade Python expertise with production patterns for Python 3.13.9, FastAPI 0.115.x, Django 5.2 LTS, Pydantic v2, SQLAlchemy 2.0; activates for API development, ORM usage, async patterns, testing frameworks, and production deployment strategies.

Rails project implementation, testing, and documentation support. Use this skill when working on Rails projects for implementing new features, adding tests to existing code, updating documentation, creating CRUD operations, building API endpoints, adding authentication, or any Rails development task. Triggers on Rails-specific implementation requests.

This skill should be used when creating a new .md file, completing an analysis or audit, deciding whether to archive or delete docs, or when uncertain if something should be documented. Covers document types, naming conventions, the "Link Test", and when to extract patterns to skills.

Server-side rendering patterns for Composable Svelte. Use when implementing SSR, hydration, server rendering, isomorphic code, or working with meta tags and SEO. Covers renderToHTML, hydrateStore, server-side routing, state serialization, and avoiding common SSR pitfalls.

Enforces test-driven development workflow for Claude Code. Implements Red-Green-Refactor cycle with configurable gates. Use when writing code, implementing features, or fixing bugs.

Build, test, or manage the Gradle multi-module monorepo. Use when building, testing, or debugging build issues across backend, frontend, or analytics.

Use when working with Rails projects, ActiveRecord models, controllers, routes, or Rails-specific patterns. Covers naming conventions, models, migrations, service objects, and testing with RSpec.

Essential exploitation payloads: anti-virus test files, file name exploits, malicious files. Curated for testing.

Comprehensive backend development guide for Node.js/NestJS/TypeScript microservices. Use when creating controllers, services, database access, middleware, DTOs, or working with NestJS APIs, dependency injection, or async patterns. Covers layered architecture (controllers → services → dbservice), error handling, performance monitoring, testing strategies.

Manage multiple development environment profiles (dev/test/staging/prod). Use when developers need to switch between environments, validate configuration, manage secrets, or ensure environment parity. Supports profile switching, variable validation, secret encryption, and environment-specific configurations.

Blazor component testing with bUnit. Use when writing unit tests for Blazor components, testing user interactions, mocking services/dependencies, testing MudBlazor components, testing components with Neatoo domain objects, or debugging component rendering issues.

Conduct sensitivity analyses to test robustness of findings. Use when: (1) Testing assumption violations, (2) Meta-analysis robustness, (3) Handling missing data, (4) Examining outliers.

Pick and run the smallest correct validation step (checks → focused Jest by path → broader suites). Use whenever you modify code and need confidence quickly.

Use when implementing any feature or bugfix before writing implementation code

Guide for writing Go tests following this project's patterns including httptest, test organization, and coverage requirements.

Generate comprehensive test suites ensuring 80%+ coverage for DevPortfolio. Use when asked to write tests, generate test suites, increase coverage, or create test cases. Generates Vitest + React Testing Library tests following AAA pattern with accessibility and i18n tests.

Introduce test-driven development to beginners with simple Flask/Sinatra test examples and TDD concepts

Develop and test API routes in the Next.js App Router. Use this when the user asks to create, modify, test, or debug API endpoints, handle API responses, validate request parameters, or work with the /api directory.

Design and implement visual regression testing for UI changes. Definesscreenshot coverage, rendering stabilization, baseline management, and CIintegration (e.g., Playwright screenshots, Percy/Chromatic). Use whenUI/styling/layout changes need protection against regressions, or when addingscreenshot-based tests to a web/WASM/desktop UI.

This skill should be used when estimating development time for Jira tickets. It provides both manual and AI-assisted estimates with T-shirt sizes, story points, and phase-by-phase time breakdowns based on task type classification, complexity scoring, and project architecture (monolithic/serverless/frontend/fullstack/mobile/test_automation).
