SOLID design principles. Covers SRP, OCP, LSP, ISP, DIP. Use when designing classes and modules. USE WHEN: user mentions "SOLID", "single responsibility", "open closed", "Liskov", "interface segregation", "dependency inversion", "dependency injection", asks about "class design", "OOP principles", "extensibility", "abstraction", "how to design classes" DO NOT USE FOR: General code quality - use `clean-code` instead, Specific patterns - use design patterns skills, Language-specific OOP - use framework-specific skills

Use this skill when you have structured course content (or any chapter-based dataset) in markdown form and need to turn it into a working interactive website — without picking a framework, without a build step.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
