Prompt

We need to check whether ArchUnitNET is already installed in our .NET solution projects. What exact command should we use to search our project files for existing installation references?

What was checked, without and with the skill
Checked	Without skill	With skill
The command uses ripgrep to search for TngTech.ArchUnitNET.	Missed	Passed
The command filters for csproj files.	Passed	Passed

ArchUnitNET for .NET

Trigger On

the repo uses or wants ArchUnitNET
architecture testing needs richer modeling than simple dependency checks

Value

produce a concrete project delta: code, docs, config, tests, CI, or review artifact
reduce ambiguity through explicit planning, verification, and final validation skills
leave reusable project context so future tasks are faster and safer

Do Not Use For

the lightest possible architecture rule checks

Inputs

the nearest AGENTS.md
target assemblies
architecture boundaries and naming conventions

Quick Start

Read the nearest AGENTS.md and confirm scope and constraints.
Run this skill's Workflow through the Ralph Loop until outcomes are acceptable.
Return the Required Result Format with concrete artifacts and verification evidence.

Workflow

Load the architecture once per test assembly where possible.
Encode a small number of durable, high-value architecture rules first.
Use the test-framework-specific integration package that matches the repo.

Bootstrap When Missing

Use when a repo wants lightweight, fluent architecture assertions for namespaces, dependencies, or layering. USE FOR: the repo uses or wants NetArchTest.Rules; architecture rules should be enforced in automated tests. DO NOT USE FOR: very rich architecture modeling that needs a heavier DSL.
