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

1. Keep rules readable and close to the boundary they protect.
2. 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' .

1. Add the package to the architecture test project:

• dotnet add TEST_PROJECT.csproj package NetArchTest.Rules

1. Add at least one executable boundary rule test.
2. Wire architecture tests into the standard test command in AGENTS.md and CI.
3. Run dotnet test TEST_PROJECT.csproj and return status: configured or status: improved.
4. 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

1. Execute one planned step and produce a concrete delta.
2. Review the result and capture findings with actionable next fixes.
3. Apply fixes in small batches and rerun the relevant checks or review steps.
4. Update the plan after each iteration.
5. Repeat until outcomes are acceptable or only explicit exceptions remain.
6. 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.
