This comprehensive guide serves as a decision flowchart for developers using Claude Code. It details when to use specific slash commands (/plan, /compact, /loop), select specialized agents (planner, code-reviewer, build-error-resolver), or invoke workflow skills (e2e-testing, tdd-workflow). It helps users select the optimal tool combination for complex tasks across the entire software development lifecycle, including feature planning, bug fixing, testing, and architectural design.

This skill performs a proactive, comprehensive audit to quantify the business and regulatory impact of a potential data breach before it occurs. It inventories sensitive data (PII, PHI, PCI-DSS), traces complex data flows through the codebase, identifies all exposure vectors, and calculates the 'blast radius.' The output provides law-sourced figures (e.g., GDPR, CCPA, HIPAA fine maximums) alongside heuristic risk estimates, guiding proactive hardening roadmaps for compliance and security.

Captures complete, full-page screenshots of any modern web page using the Chrome DevTools Protocol (CDP). Unlike standard tools, this utility handles Single Page Applications (SPAs), scrolling content, lazy-loaded images, and complex scroll containers, ensuring the entire visible content is captured in a single, high-fidelity PNG file. Ideal for documenting complex web flows and testing.

A comprehensive guide for building robust GraphQL APIs using Golang. Covers critical best practices including advanced schema design (nullability, pagination, mutations), optimizing resolvers, and preventing N+1 database queries using DataLoaders. Ideal for engineers building high-performance, production-grade backend services.

This skill guides the systematic migration of Java enterprise code from the legacy `javax.*` namespace to the modern `jakarta.*` namespace. It is essential for developers upgrading applications to Jakarta EE 10 or running on Tomcat 11+. The process covers updating imports, modifying dependency coordinates in build files (pom.xml), and adapting web deployment descriptors.

Expert assistance for building, modifying, and debugging Minecraft server plugins for the Paper, Spigot, and Bukkit ecosystems. This includes implementing complex gameplay mechanics such as minigames, advanced combat systems, persistent player progression (perks, economy, quests), custom command handling, and robust state management. We handle configuration, listener registration, and adherence to best practices for Java-based server API usage.

This tool analyzes and refactors code to detect and correct anemic domain models. It enforces rich domain modeling patterns (Entities, Value Objects, Aggregates, Domain Events), improving encapsulation and business logic ownership. Use it when validating, reviewing, or refactoring core domain logic to ensure adherence to Domain-Driven Design (DDD) principles.

This skill performs comprehensive, feature-level integration validation after all associated development tasks are implemented. It goes beyond checking individual tasks to ensure cross-task consistency, full test suite passage, and complete specification coverage. It validates data flow, architectural adherence, and performs critical security scans for residual issues (e.g., TODOs, hardcoded secrets), providing a holistic GO/NO-GO assessment for deployment. Use this skill as a final quality gate to verify that the completed feature set respects the designed boundaries and dependencies end-...

This tool assists engineers in transforming vague work logs into structured, evidence-backed impact statements for professional documentation. It uniquely mines Copilot CLI session logs, git commits, and GitHub PRs to reconstruct forgotten work. It enforces a mandatory 'Action → Result → Evidence' impact contract, making it indispensable for preparing performance reviews, promotion packets, and self-assessments.

This guide details how to use the `go.uber.org/dig` library for dependency injection in Go. It covers advanced concepts like constructor registration (`Provide`), service invocation (`Invoke`), parameter grouping (`dig.In`), result structuring (`dig.Out`), named dependencies, and value groups. It is essential for wiring up application graphs at startup in complex Go applications.

A robust application framework for Go, built on the uber-go/dig container. It provides advanced features essential for long-running services, including structured dependency injection, explicit lifecycle hooks (OnStart/OnStop), modular composition, and signal-aware graceful shutdown handling. Ideal for building robust daemons, HTTP servers, and background workers.

This skill guides the process of transforming private, repetitive operational workflows developed in Hermes into sanitized, reusable artifacts suitable for the public ECC layer. It ensures that sensitive data, local file paths, personal credentials, and private state are stripped out, allowing the core pattern to be safely published for broader use.
