Testing & Security

SQL Server administration and maintenance. Use for database backups, security, user management, maintenance tasks, monitoring, and troubleshooting.

Testing guidelines for Bun/TypeScript projects using bun:test framework. Use when writing tests, creating test files, debugging test failures, setting up mocks, or reviewing test code. Triggers on *.test.ts files, test-related questions, mocking patterns, and coverage discussions.

Create Claude Code subagents from natural language requirements. Use when users want to create specialized AI subagents for Claude Code without manually writing the configuration. Handles agent creation for testing, code review, debugging, documentation, refactoring, and custom workflows. Generates .claude/agents/*.md files with appropriate YAML frontmatter and system prompts.

Creates and optimizes MSW (Mock Service Worker) handlers for Playwright E2E tests, implementing handler caching, fixture management, and AI Gateway mocking patterns. Use when mock setup is slow or test data needs centralization.

Configuring Claude Code settings.json & Security. Set up permissions (allow/deny), permission modes, environment variables, tool restrictions. Use when securing Claude Code, restricting tool access, or optimizing session settings.

Systematic debugging framework ensuring root cause investigation before fixes. Includes four-phase debugging process, backward call stack tracing, multi-layer validation, and verification protocols. Use when encountering bugs, test failures, unexpected behavior, performance issues, or before claiming work complete. Prevents random fixes, masks over symptoms, and false completion claims.

Enforces visibility pattern for testability by detecting private methods that prevent unit testing (causes 20-40% coverage loss). References authoritative style guides rather than duplicating. Auto-refactors code to private[module] object pattern with user approval. Detects inline lambdas and suggests extraction to named functions ("laws"). Blocks during scala-ninja review (Phase 2) as peer review rejection point.

Playwright E2E testing setup and configuration. Use when setting up end-to-end tests.

Harness CI (Continuous Integration) for container-native builds with test intelligence, caching, parallelization, and build infrastructure management

WordPress custom theme development specialist focused on clean, maintainable code following VIP standards. Includes modular theme structure, dart-sass via Homebrew, proper script/style enqueueing, template parts organization, text domain management, and comprehensive security practices (escaping, sanitization, file paths).

Review code for quality, security, and best practices. Invoke when reviewing PRs, checking code quality, or analysing implementations.

Perform accessibility audit on web pages. Use when users ask to check accessibility, audit WCAG compliance, verify ARIA usage, check color contrast, audit keyboard navigation, or analyze screen reader compatibility. Detects ARIA issues, focus problems, contrast issues, and semantic HTML violations.

Industry-specific workflow patterns and templates for finance, healthcare, logistics, manufacturing, retail, and common use cases like AI document processing, API integration, business rules, ETL, RAG, security, and project management. Use when asking about 'workflow examples', 'workflow templates', 'industry workflows', 'finance workflows', 'healthcare workflows', 'logistics workflows', 'manufacturing workflows', 'retail workflows', 'ETL workflows', 'RAG workflows', 'API workflows', 'document processing', 'business rules', or 'workflow patterns'.

Master Bash Automated Testing System (Bats) for comprehensive shell script testing. Use when writing tests for shell scripts, CI/CD pipelines, or requiring test-driven development of shell utilities.

WordPress plugin and theme testing with PHPUnit integration tests, WP_Mock unit tests, PHPCS coding standards, and CI/CD workflows

Phoenix Framework with LiveView on the BEAM. Covers OTP foundations, context-driven domain modeling, Ecto data layer, LiveView real-time patterns, PubSub/Presence, testing, performance, and deployment with releases.

Run the NOVAE loop (Sequential Thinking → Context7 QA → Parallel Tasks → Integration → Tests) for React/TypeScript + Express projects like ProAgentic. Use for features, bug fixes, or refactors that must be validated end-to-end. Prioritize user flows, Playwright MCP, and safety (never kill processes).

Implements Z-Wave CTT (Certification Test Tool) test handlers for automating certification tests. Use when asked to create handlers for a given test, which includes automating CTT log parsing and prompt responses.

Systematic code review using quality gates, SOLID principles, error handling patterns, and test coverage analysis. Provides structured feedback with severity levels and actionable improvements.
