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.

What it costs to keep this loaded
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 5.1 | $0.00112 | $0.00917 |
| Opus 5.5 | $0.00045 | $0.00367 |
| Sonnet 5.5 | $0.00022 | $0.00183 |
| Haiku 4.5 | $0.00011 | $0.00092 |
Grade A, and why
netarchtest 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 1mo 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.

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
- 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
- Encode only durable architecture rules:
- forbidden dependencies
- namespace layering
- type shape conventions
- Keep rules readable and close to the boundary they protect.
- Fail tests on architecture drift, not on temporary style noise.
Bootstrap When Missing
If NetArchTest.Rules is not configured yet:
- Detect existing setup:
rg -n "NetArchTest\\.Rules" -g '*.csproj' .
- Add the package to the architecture test project:
dotnet add TEST_PROJECT.csproj package NetArchTest.Rules
- Add at least one executable boundary rule test.
- Wire architecture tests into the standard
testcommand inAGENTS.mdand CI. - Run
dotnet test TEST_PROJECT.csprojand returnstatus: configuredorstatus: improved. - If richer modeling is required and
ArchUnitNETis chosen as the standard, returnstatus: 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.
What ships with it
4 files 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.
- 1mo ago First seen · 106 lines · 112 tokens per session scan A 2ae85c2c6bed
netarchtest is a skill published in the GitHub repository managedcode/dotnet-skills (495 stars, last pushed yesterday), licensed MIT. It adds 112 tokens to every session and 917 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
