Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00044 | $0.00896 |
| Opus 5 | $0.00022 | $0.00448 |
| Sonnet 5 | $0.00009 | $0.00179 |
| Haiku 4.5 | $0.00004 | $0.00090 |
Grade A, and why
mcaf-dotnet-archunitnet scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
88% identical to archunitnet — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

MCAF: .NET ArchUnitNET
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.mdand confirm scope and constraints. - Run this skill's
Workflowthrough theRalph Loopuntil outcomes are acceptable. - Return the
Required Result Formatwith 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
If ArchUnitNET is not configured yet:
- Detect existing setup:
rg -n "TngTech\\.ArchUnitNET" -g '*.csproj' .
- Add packages to the architecture test project:
dotnet add TEST_PROJECT.csproj package TngTech.ArchUnitNET- add one framework bridge package:
TngTech.ArchUnitNET.xUnit,TngTech.ArchUnitNET.xUnitV3,TngTech.ArchUnitNET.MSTestV2, orTngTech.ArchUnitNET.TUnit
- Add at least one durable boundary rule test.
- Wire architecture tests into the standard
testcommand inAGENTS.mdand CI. - Run
dotnet test TEST_PROJECT.csprojand returnstatus: configuredorstatus: improved. - If
NetArchTestalready covers the same boundary policy and no gap exists, returnstatus: not_applicable.
Deliver
- architecture tests with richer domain and type modeling
- architecture-rule commands wired into repo test flow and CI expectations

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mcaf-dotnet-archunitnet is a skill published in the GitHub repository managedcode/dotPilot (23 stars, last pushed 4mo ago), licensed MIT. It adds 44 tokens to every session and 896 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to archunitnet, differing in 10 lines, and is treated as a copy.
