Skill UI

Opinionated Terraform workflow skill that guides module design, state/backend management, provider patterns, security hardening, policy-as-code checks, and CI/CD plan/apply flows so IaC stays modular, compliant, and reliable.

A comprehensive guide and technique set for detecting and exploiting race condition vulnerabilities in web applications. It focuses on bypassing rate limits, exploiting Time-of-Check-to-Time-of-Use (TOCTOU) flaws, and duplicating transactions using advanced methods like Turbo Intruder's single-packet attack. Ideal for security assessments of state-changing operations (e.g., payments, inventory management, coupon redemption).

This skill covers the complete lifecycle for establishing, implementing, and maintaining an Information Security Management System (ISMS) based on ISO/IEC 27001:2022. Users learn the full process, from initial gap analysis and risk assessment (including defining risk treatment plans) to selecting Annex A controls, developing the Statement of Applicability (SoA), conducting internal audits, and preparing for final certification. It is essential for organizations needing to achieve formal security compliance and robust governance.

Automatically reverse-engineers any codebase (frontend, backend, or fullstack) into a comprehensive Product Requirements Document (PRD). It analyzes complex elements like routes, components, API integrations, state management, and business logic across major stacks (React, Vue, Next.js, Django, FastAPI). The resulting PRD is detailed enough for both product managers (understanding 'what') and engineers/AI agents (understanding 'how' to reconstruct the system).

A comprehensive architectural guide for building and maintaining macOS menubar utilities using SwiftUI and Tuist. It enforces strict separation of concerns by guiding developers to keep networking, state management, and UI presentation in distinct, testable layers, ensuring robust and scalable application development.

A comprehensive guide detailing proven patterns for building robust and scalable SwiftUI applications. Covers modern state management (@State, @Observable), advanced navigation (Sheets, NavigationStack), handling asynchronous data flows, and adhering to architectural best practices to create maintainable, performant UIs.

This tool serves as a persistent memory and state manager for complex coding projects within the Claude environment. It allows users to initialize new projects with structured metadata, track detailed session progress (including summaries, decisions, and next steps), and save the entire context reliably. By ensuring project continuity across disconnected sessions, it drastically improves the flow and consistency of the development workflow.

This technique audits user interaction flows (like button clicks) to detect subtle bugs that static analysis often misses. It specifically tracks the full sequence of state changes, identifying instances where later actions unintentionally cancel, contradict, or leave the UI in an inconsistent state due to state store side effects or race conditions. Ideal for debugging complex state management architectures (Redux, Zustand).

A comprehensive, library-agnostic checklist covering best practices for Flutter and Dart applications. It guides developers on architectural principles, state management patterns (BLoC, Riverpod, etc.), Dart idioms, performance optimization, and clean code principles, making it invaluable for code reviews.

A comprehensive operational guide for support teams to manage complex customer billing workflows. It assists operators in diagnosing billing anomalies, processing refunds, triaging charges, and recovering customer portals. Use this when investigating billing discrepancies, assessing churn risk, or ensuring accurate subscription state and revenue management.

A comprehensive guide to idiomatic and robust Dart/Flutter patterns. Covers essential topics including null safety, immutable state management (Freezed), advanced state solutions (BLoC, Riverpod, Provider), reactive routing with GoRouter, secure networking using Dio, and implementing Clean Architecture principles. Ideal for setting up new, scalable Flutter projects.

A comprehensive guide covering how to design, implement, and test state management using the bloc and flutter_bloc packages. Learn best practices for modeling state (sealed classes vs. enums), differentiating between Cubit and Bloc, handling naming conventions, and structuring your application architecture for scalability and testability.
