Integrate real-world street networks into VRP problems using OpenStreetMap data. Use when loading real map data, creating instances from actual locations, computing network-based distances, or building tutorials with real-world scenarios. Guides through installation, loading areas, extracting nodes, computing distance matrices, and creating PDPTW instances from map data.

This skill should be used when the user asks about "game rules", "scoring", "phases", "Attack token", "Exploit token", "Ghost token", "tile placement rules", "path matching", "movement rules", "winning conditions", "turn actions", "firewall breach", "path segments", "edge nodes", or discusses Zero-Day Attack game mechanics and design.

分层架构规范 / Architecture and layering rules (v0.3.1)。在设计新组件、修改导入、检查分层时使用。核心约束：cli → flows → data，core 向内不向外。Use when designing components, changing imports, or reviewing layering decisions. Enforces cli/flows/core/data separation.

Comprehensive backend development guide for Node.js/Express/TypeScript microservices. Use when creating routes, controllers, services, repositories, middleware, or working with Express APIs, Prisma database access, Sentry error tracking, Zod validation, unifiedConfig, dependency injection, or async patterns.

Guide for the inter-host agent API system. Use when adding capabilities to hosts, writing handlers, understanding the GC protocol, or debugging agent call issues.

Use when implementing reduced motion alternatives, vestibular-safe animations, WCAG compliance, or designing for users with motion sensitivity.

Guide decision-making using principles and trade-off analysis frameworks. Use when making technical decisions, evaluating alternatives, designing solutions, or choosing between options. Helps establish lasting principles.

This skill should be used when creating extensions for Claude Code or OpenCode, including plugins, commands, agents, skills, and custom tools. Covers both platforms with format specifications, best practices, and the ai-eng-system build system.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Use when completing tasks, implementing major features, or before merging to verify work meets requirements - dispatches superpowers:code-reviewer subagent to review implementation against plan or requirements before proceeding

Scaffolds new frontend pages/features with TDD approach, following established UI patterns from BuildProject/Baker pages. Generates page component, test file, updates routing, and maintains 90%+ test coverage before implementing production code. Use this when creating new pages or features in the Bucket app.

Comprehensive security specialist that performs vulnerability assessments, secure code reviews, dependency audits, and provides remediation guidance following OWASP, CWE, and industry security standards

This skill should be used when working with the Ghostmind development system, which uses meta.json as a central configuration for Docker, Compose, Terraform, and Tmux. Use this skill when creating or modifying configurations for any of these components, setting up new applications, or understanding how the system components interconnect.
