C# coding conventions, idiomatic patterns, performance, and async best practices for both .NET 8 (C# 12) and .NET 10 (C# 14). Use when writing, reviewing, refactoring, or designing C# code — including async code that uses Task, Task<T>, ValueTask,…

Use when a .NET process is slow, hung, memory-heavy, or deadlocked, or when analyzing C#/ASP.NET Core code for performance anti-patterns across memory, async, LINQ, database, JSON, caching, DI, concurrency, HttpClient, exceptions, response, strings, startup,…

Performs a systematic C#/ASP.NET Core security code review on .NET 8 (C# 12) and .NET 10 (C# 14) codebases. Covers OWASP Top 10, authentication/authorization audit, input validation, cryptography, dependency vulnerabilities, security headers, middleware…

create, repair, compress, and optimize prompts, system messages, tool instructions, schemas, and eval rubrics for general tasks across writing, research, coding, analysis, planning, tutoring, automation, and agent workflows. use when the user wants a new…

Use when proving MCC behavior on a real local Minecraft server, validating runtime or protocol changes end-to-end, exercising movement, physics, inventory, entity, chat, or terrain behavior, or running a single-version or cross-version regression sweep.

Adapt MCC palettes and protocol handling for a new Minecraft version. Use when the user wants to add support for a new MC version, compare version registries, update item/entity/block/metadata palettes, or fix protocol mismatches between MC versions.

Creating and refining Mermaid diagrams with live reload. Use when users want flowcharts, sequence diagrams, class diagrams, ER diagrams, state diagrams, or any other Mermaid visualization. Provides best practices for syntax, styling, and the iterative…

Build, run, and debug Minecraft Console Client (MCC) against a real local Minecraft Java server on Linux, macOS, or WSL. Use this whenever the user wants to compile MCC, start or inspect a local test server, connect MCC to a server, debug protocol or login…

Use when English text must be parsed without a human to resolve ambiguity — tool descriptions, error messages, inter-agent instructions, system prompts, status reports — and misreading has a real cost, or when text reads as dense, hedged, or easy to misparse.…

C# coding conventions, idiomatic patterns, performance, and async best practices for both .NET 8 (C# 12) and .NET 10 (C# 14). Use when writing, reviewing, refactoring, or designing C# code — including async code that uses Task, generic Task results,…

Apply SOLID principles pragmatically to C# and .NET code. Use this skill whenever the user asks to explain, review, refactor, design, or critique C#/.NET code for maintainability, extensibility, cohesion, coupling, testability, dependency injection, interface…

Use when a .NET process is slow, hung, memory-heavy, or deadlocked, or when analyzing C#/ASP.NET Core code for performance anti-patterns across memory, async, LINQ, database, JSON, caching, DI, concurrency, HttpClient, exceptions, response, strings, startup,…

Run UMPK end-to-end tests against isolated local vanilla Minecraft Java servers. Use for live protocol, lifecycle, movement, inventory, registry, proxy, or version-matrix validation where unit tests are insufficient.
