Testing & Security

Use when adding debug-only deep links for testing, enabling simulator navigation to specific screens, or integrating with automated testing workflows - enables closed-loop debugging without production deep link implementation

Use for Core Location troubleshooting - no location updates, background location broken, authorization denied, geofence not triggering

Use when implementing in-app purchases, StoreKit 2, subscriptions, or transaction handling - testing-first workflow with .storekit configuration, StoreManager architecture, transaction verification, subscription management, and restore purchases for consumables, non-consumables, and auto-renewable subscriptions

Use when writing unit tests, adopting Swift Testing framework, making tests run faster without simulator, architecting code for testability, testing async code reliably, or migrating from XCTest - covers @Test/@Suite macros,

Use when integrating App Intents for Siri, Apple Intelligence, Shortcuts, Spotlight, or system experiences - covers AppIntent, AppEntity, parameter handling, entity queries, background execution, authentication, and debugging common integration issues for iOS 16+

Use when implementing BGTaskScheduler, debugging background tasks that never run, understanding why tasks terminate early, or testing background execution - systematic task lifecycle management with proper registration, expiration handling, and Swift 6 cancellation patterns

Use when app drains battery, device gets hot, users report energy issues, or auditing power consumption - systematic Power Profiler diagnosis, subsystem identification (CPU/GPU/Network/Location/Display), anti-pattern fixes for iOS/iPadOS

Use for Core Location API reference - CLLocationUpdate, CLMonitor, CLServiceSession, authorization, background location, geofencing

Vulnerability review, OWASP patterns, secure coding practices, and threat modeling approaches. Use when reviewing code security, designing secure systems, performing threat analysis, or validating security implementations.

Test charter structure, SFDPOT and FEW HICCUPPS heuristics, edge case discovery patterns, and session-based test management. Use when conducting exploratory testing, discovering edge cases, validating user journeys, or finding issues automated tests miss.

Identify existing codebase patterns (naming conventions, architectural patterns, testing patterns) to maintain consistency. Use when generating code, reviewing changes, or understanding established practices. Ensures new code aligns with project conventions.

Apply test pyramid principles, coverage targets, and framework-specific patterns. Use when designing test suites, reviewing test coverage, or implementing tests. Covers Jest, Pytest, and common testing frameworks with naming conventions and organization patterns.

Apply consistent security, performance, and accessibility standards across all recommendations. Use when reviewing code, designing features, or validating implementations. Cross-cutting skill for all agents.

WCAG 2.1 AA compliance patterns, screen reader compatibility, keyboard navigation, and ARIA best practices. Use when implementing accessible interfaces, reviewing UI components, or auditing accessibility compliance. Covers semantic HTML, focus management, color contrast, and assistive technology testing.

Systematic code review patterns, quality dimensions, anti-pattern detection, and constructive feedback techniques. Use when reviewing code changes, assessing codebase quality, identifying technical debt, or mentoring through reviews. Covers correctness, design, security, performance, and maintainability.

Discover patterns, rules, and interfaces through iterative analysis cycles. Use when analyzing business rules, technical patterns, security, performance, integration points, or domain-specific areas. Includes cycle pattern for discovery to documentation to review workflow.

Test pyramid strategy, test design patterns, coverage analysis, and quality gate configuration. Use when designing test strategies, improving coverage, setting up automation, or defining quality gates. Covers unit, integration, and E2E testing across frameworks.

Interview techniques, persona creation, journey mapping, and usability testing patterns. Use when planning research, conducting user interviews, creating personas, mapping user journeys, or designing usability tests. Essential for user-research, requirements-analysis, and interaction-architecture agents.

REST and GraphQL API design patterns, OpenAPI/Swagger specifications, versioning strategies, and authentication patterns. Use when designing APIs, reviewing API contracts, evaluating API technologies, or implementing API endpoints. Covers contract-first design, resource modeling, error handling, pagination, and security.

Coordinate multi-agent code review with specialized perspectives. Use when conducting code reviews, analyzing PRs, evaluating staged changes, or reviewing specific files. Handles security, performance, quality, and test coverage analysis with confidence scoring and actionable recommendations.
