Deep architectural context building for security audits. Use when conducting security reviews, building codebase understanding, mapping trust boundaries, or preparing for vulnerability analysis. Inspired by Trail of Bits methodology.
Use when implementing 'iCloud Drive', 'ubiquitous container', 'file sync', 'NSFileCoordinator', 'NSFilePresenter', 'isUbiquitousItem', 'NSUbiquitousKeyValueStore', 'ubiquitous file sync' - comprehensive file-based iCloud sync reference
Security vulnerability detection and variant analysis skill. Use when hunting for dangerous APIs, footgun patterns, error-prone configurations, and vulnerability variants across codebases. Combines sharp edges detection with variant hunting methodology.
QA an analysis before sharing with stakeholders — methodology checks, accuracy verification, and bias detection. Use when reviewing an analysis for errors, checking for survivorship bias, validating aggregation logic, or preparing documentation for reproducibility.
SEO optimization with keyword analysis, readability assessment, technical validation, content quality. Use for search rankings, blog posts, content audits, or encountering keyword density, readability scores, meta tags, schema markup errors.
Build React Native 0.76+ apps with Expo SDK 52. Covers mandatory New Architecture (0.82+), React 19 changes (propTypes/forwardRef removal), new CSS (display: contents, mixBlendMode, outline), Swift iOS template, and DevTools migration. Use when: building Expo apps, migrating to New Architecture, or troubleshooting "Fabric component not found", "propTypes not a function", "TurboModule not registered", or Swift AppDelegate errors.
Use this to write commit messages unless specific commit message conventions are explicitly specified.
Create standalone debugging interfaces that reveal the internal workings of complex systems through interactive visualization. Use when the user wants to understand how something works, debug internal state, visualize data flow, see what happens when they interact with the system, or build a debug panel for any complex mechanism. Triggers on requests like "I don't understand how this works", "show me what's happening", "visualize the state machine", "build a debug view for this", "help me see the data flow", "make this transparent", or any request to understand, debug, or visualize internal system behavior. Applies to state machines, rendering systems, event flows, algorithms, animations, data pipelines, CSS calculations, database queries, or any system with non-obvious internal workings.
C++20 specialist with expertise in modern C++ features, performance optimization, and system programming
Schema design guide for polizy authorization. Use when defining relations, actions, action mappings, hierarchy propagation, or modifying authorization models. Covers direct, group, and hierarchy relation types.
