What it does

Netarchtest is an agent skill from managedcode/dotnet-skills. Use the open-source free NetArchTest.Rules library for architecture rules in .NET unit tests. 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. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when…

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `manifest.json`, `references/examples.md` and `references/netarchtest.md`). Compatibility notes: Requires a .NET test project; works with any unit-test framework.

It sits in Agent Workflows, covering Codebase knowledge for agents and Unit testing. It works with .NET. The repository describes itself as: Installable .NET skill catalog and CLI for Codex, Claude Code, GitHub Copilot, and Gemini. The licence is MIT.

When your agent uses it

  • A repo wants lightweight
  • Fluent architecture assertions for namespaces
  • : the repo uses
  • Wants NetArchTest.Rules

Example prompts

  • “/netarchtest”

Requirements

  • Compatibility (from SKILL.md): Requires a .NET test project; works with any unit-test framework.

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

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

What it can do on your machine

Read from SKILL.md and the folder at commit 535dd55. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • dotnet
    • rg

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Requires a .NET test project; works with any unit-test framework.

    From compatibility in the SKILL.md frontmatter.

Context cost

Netarchtest loads about 1k tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 136 tokens; SKILL.md has 459 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~136
When it runs · the whole SKILL.md, loaded when a task matches
~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

NetArchTest

Trigger On

  • the repo uses or wants NetArchTest.Rules
  • architecture rules should be enforced in automated tests

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

  • very rich architecture modeling that needs a heavier DSL

Inputs

  • the nearest AGENTS.md
  • architecture boundaries to enforce
  • target assemblies

Quick Start

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

Workflow

  1. Encode only durable architecture rules:
    • forbidden dependencies
    • namespace layering
    • type shape conventions
  2. Keep rules readable and close to the boundary they protect.
  3. Fail tests on architecture drift, not on temporary style noise.

Bootstrap When Missing

If NetArchTest.Rules is not configured yet:

  1. Detect existing setup:
    • rg -n "NetArchTest\\.Rules" -g '*.csproj' .
  2. Add the package to the architecture test project:
    • dotnet add TEST_PROJECT.csproj package NetArchTest.Rules
  3. Add at least one executable boundary rule test.
  4. Wire architecture tests into the standard test command in AGENTS.md and CI.
  5. Run dotnet test TEST_PROJECT.csproj and return status: configured or status: improved.
  6. If richer modeling is required and ArchUnitNET is chosen as the standard, return status: not_applicable.

Deliver

  • architecture tests that are understandable and stable
  • boundary checks wired into the normal test path used by agents and CI

Validate

  • the rules map to real boundaries the team cares about
  • failures point to actionable dependency drift

Ralph Loop

Use the Ralph Loop for every task, including docs, architecture, testing, and tooling work.

  1. Plan first (mandatory):
    • analyze current state
    • define target outcome, constraints, and risks
    • write a detailed execution plan
    • list final validation skills to run at the end, with order and reason
  2. Execute one planned step and produce a concrete delta.
  3. Review the result and capture findings with actionable next fixes.
  4. Apply fixes in small batches and rerun the relevant checks or review steps.
  5. Update the plan after each iteration.
  6. Repeat until outcomes are acceptable or only explicit exceptions remain.
  7. If a dependency is missing, bootstrap it or return status: not_applicable with explicit reason and fallback path.
Required Result Format
  • status: complete | clean | improved | configured | not_applicable | blocked
  • plan: concise plan and current iteration step
  • actions_taken: concrete changes made
  • validation_skills: final skills run, or skipped with reasons
  • verification: commands, checks, or review evidence summary
  • remaining: top unresolved items or none

For setup-only requests with no execution, return status: configured and exact next commands.
