Testing & Security

Writes comprehensive tests with edge cases during test phase

Build responsive, mobile-first user interfaces that adapt gracefully across all screen sizes using fluid layouts, relative units, breakpoints, and optimized assets. Use this skill when creating or modifying UI layouts, responsive components, CSS media queries, or any code that needs to adapt to different viewport sizes. Use this when implementing mobile-first designs, adding responsive breakpoints (mobile/tablet/desktop), using relative units (rem/em), ensuring touch-friendly tap targets, optimizing images for different screen sizes, testing across multiple devices, or making typography readable on all screens. Use this when working on layout components, grid systems, or any UI code that should respond to screen size changes.

Write failing test first, then minimal code to pass. Red-Green-Refactor cycle.Use when: implementing features, fixing bugs, refactoring code.Triggers: "implement", "add feature", "fix bug", "tdd", "test first","write tests", "test-driven".

Use when designing test strategies, implementing test automation, or optimizing performance

Validate and debug Vercel AI SDK provider configurations including API keys, environment setup, model compatibility, and rate limiting. Use when encountering provider errors, authentication failures, API key issues, missing environment variables, model compatibility problems, rate limiting errors, or when user mentions provider setup, configuration debugging, or SDK connection issues.

Conversion Rate Optimization patterns beyond A/B testing. Heatmaps, session recordings, funnel analysis, form analytics, exit intent. Data-driven optimization.

Generates comprehensive test files for functions and classes. Use after writing a function, method, or class to quickly create unit tests with edge cases, assertions, and proper test structure. Supports multiple testing frameworks (pytest, unittest, jest, etc.) and follows testing best practices (AAA pattern, mocking, fixtures).

Generate and manage static audio files for Bob The Skull using ElevenLabs TTS. Use when creating greetings, startup messages, error responses, or test audio. Handles generation, naming, directory structure, and cross-repo syncing.

Validate Dokploy templates against conventions: YAML syntax, network structure, health checks, environment variables, security patterns, and quality standards.

Systematic test debugging with 5-phase investigation workflow. Use when debugging test failures, investigating complex errors, or when AI consultation would help. Uses native test commands with optional AI consultation for complex failures.

WHEN: Terraform code review, module structure, state management, security policiesWHAT: Module organization + State backend + Security policies + Variable validation + Best practicesWHEN NOT: Kubernetes → k8s-reviewer, Docker → docker-reviewer
