Agentic engineering
setups,directivesandskillsthat I use for building real-world .NET applications. Everything here has been used with real-world codebases - not generated with prompts and published untested. -
The
agentic-checktool scans your repo and automatically composes, installs and updates an optimized set of directives and skills for your tech stack, directly from best-in-class GitHub skills repo's. It also helps you compose a specialization hierarchy for the folders in your repo (e.g. to have common directives and skills in the repo root, but additional and different ones inbackendandfrontendsubfolders).
The skills available for composition are carefully tested and are selected from best-in-class GitHub skills repo's:

Demos:
- .NET Agentic Engineering (post with steps to get started)
- LiveCharts2 with Uno Platform (post with app video)
- GPT 5.4 vs Opus 4.6 for UI with Uno Platform (article with side-by-side apps video)
This repo saves .NET software engineers a significant, ongoing effort:
- filter proven engineering value from untested content and marketing in the agentic ecosystem
- fill agentic ecosystem gaps, both technology-independent and for specific technologies
- extend the agentic ecosystem with specialized technology/pattern skills for distributed/cross-platform applications
- compose an optimal set of directives and skills for your repo and tech stack, while avoiding contradictions and ambiguities that may cause agent mistakes.
Currently this repo includes technology-independent content and content specific for .NET, Microsoft Orleans and Uno Platform.
In the coming months I will be adding content for the latest .NET, Aspire, Azure, Fabric, Orleans and Uno Platform as I progress applying agentic engineering to a real-world distributed, cross-platform application that I am building with this technology stack.
👁️/⭐ this repo if this includes what you are looking for!
Install an optimized combination of models, harnesses, plugins, MCP's, skills and directives for your tech stack with these steps:
-
Check your Agentic Development Environment Setup
-
From within a folder in your repo, run:
dnx agentic.check
Run this regularly to catch skills updates and to get add directives and skills when you expand your tech stack.
Alternatively, you can manually compose and install directives and skills
This repo offers the following directives (markdown snippets to include in your AGENTS.md / CLAUDE.md):
| Directive | Description |
|---|---|
foundation-prompt-log |
Records sanitized user prompts and agent question-and-answer pairs as companion git commits so intent is preserved and can be replayed later. |
dotnet-cli-run |
Prevents long agent timeout delays from running dotnet in the background. |
dotnet-build-errors-and-warnings |
Configures .NET build warnings and errors and a modern C# .editorconfig, then directs agents to fix build errors and warnings or document rare justified suppressions. |
uno-build-and-run |
Standardizes Uno app launch for agents by skipping redundant pre-builds, writing per-run stdout logs via AGENT_CONSOLE_LOG, and verifying or stopping the app with the Uno runtime tools. |
This repo offers below skills. They are grouped in plugins for ease of manual installation, however the agentic-check tool selects or excludes each skill individually.
Skills for .NET development.
| Skill | Description |
|---|---|
cli-e2e-testing |
CLI end-to-end testing guide for real terminal flows with Hex1b automation, keyboard input, observable terminal output, and asciinema recordings. |
dotnet-livecharts2 |
LiveCharts2 development guide — installation, XAML source generator integration, theme config, gotchas, and sample index with exact repo file paths. Covers all platforms (WinUI, Uno, Avalonia, MAUI, WPF, Blazor, WinForms, Eto). |
dotnet-modern-csharp-editorconfig |
Drop-in opinionated .editorconfig for modern C# (C# 14 / .NET 10, also works with C# 10–13) — formatting, naming, style, and preview analyzer severities. Covers required .csproj flags and the .NET 8 vs .NET 9+ build-respect-editorconfig distinction. |
Skills for Microsoft Orleans 10 actor-based distributed applications.
| Skill | Description |
|---|---|
orleans-result-pattern |
Concise, version-tolerant result pattern for Orleans 8+ grain calls — Result / Result<T> with enum ErrorNr + string errors, [Immutable] for zero-copy within-silo calls, implicit conversions, and RFC7807 ValidationProblemDetails via TryAsValidationErrors. |
orleans-multiservice-pattern |
Modular-monolith pattern for Orleans 10 — host multiple logical services in one silo with strict Apis → Contracts, Apis → Service, Service → Contracts dependency rules so any logical service can later be extracted to its own physical microservice with minimal changes. |
Skills for Uno Platform cross-platform app development.
| Skill | Description |
|---|---|
uno-agentic-support |
In-app support for agent-driven Uno app runs — detects AGENT_CONSOLE_LOG, captures early stdout/stderr logging, and disables Uno Studio Hot Reload / Hot Design UI during agent UI testing. |
uno-csharpmarkup2 |
Build a Uno Platform 6 UI in pure C# with C# Markup 2 (CSharpForMarkup) — covers both the initial Presentation-project setup and ongoing per-page authoring via the included New-View.ps1 helper. MVVM/MVUX, Skia/native renderer, bind-without-strings, Spread, conditional children, and the markup/logic partial-class split. |
uno-fluent2 |
Fluent 2 Design System for Uno Platform — color, typography, geometry, materials, motion, iconography, spacing, elevation, lightweight styling, and responsive breakpoints. |
uno-hamburgermenu-databinding |
Data-bound, hierarchical hamburger menu with dynamic navigation using Uno Navigation Extensions NavigationView and MVVM. |
uno-livecharts2-theme-switching |
