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, CancellationToken, Task.WhenAll/WhenAny, Task.Run, ConfigureAwait, async void, or fire-and-forget. Trigger on `.Result`, `.Wait()`, deadlocks, cancellation propagation, ASP.NET Core background work, UI responsiveness, exception flow, and performance-sensitive async API design.

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, and metrics.

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 pipeline, and CI/CD security posture.

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 prompt, wants an existing prompt improved, wants prompt failures debugged, or needs better structure for grounding, tool use, output format, or reliability.

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 workflow using mermaid_preview and mermaid_save tools.

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 issues, validate a code change end-to-end, or run MCC commands on a real server instead of guessing from static code.

Remove signs of AI-generated writing from text. Use when editing or reviewing text to make it sound more natural and human-written. Based on Wikipedia's comprehensive "Signs of AI writing" guide. Detects and fixes patterns including: inflated symbolism, promotional language, superficial -ing analyses, vague attributions, em dash overuse, rule of three, AI vocabulary words, negative parallelisms, and excessive conjunctive phrases. Use this skill when writing documentation for MCC.

Use when creating, updating, or improving agent skills.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Create, modify, repair, and wire Minecraft Console Client ChatBots and standalone `/script` bots. Use this whenever the user wants an MCC bot, C# script bot, chat or event handlers, periodic automation, movement logic, inventory logic, plugin-channel handling, or asks to fix or port an existing bot; default to standalone `//MCCScript` bots unless the user explicitly asks for a built-in MCC bot or repo wiring.
