What is dotnet-structure?

A review of a .NET backend’s solution and folder layout. It examines projects, layers, file sizes, and the boundaries between parts of the application.

Use it to review a .NET solution, project, or directory and get suggestions for organizing projects, folders, files, and architectural layers.

It helps find tangled dependencies, misplaced responsibilities, oversized files, and structures that make a codebase harder to understand or change.

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.

Token cost

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	$0.00024	$0.00466
Opus 5	$0.00012	$0.00233
Sonnet 5	$0.00005	$0.00093
Haiku 4.5	$0.00002	$0.00047

Security

Grade A, and why

dotnet-structure 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 3d 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.

What it actually says

Analyze the .NET backend structure. If $ARGUMENTS is provided, analyze that solution, directory, or project. Otherwise auto-detect the main backend solution.

First: Use the dotnet-backend-expert skill. Read references/project-structure.md and references/architecture.md.

Analysis Steps

Map the solution:
- list *.sln and *.csproj
- classify projects as API/host, AppHost, contracts, application, domain, infrastructure, workers, tests
- detect whether the codebase is layered, vertical slice, modular monolith, or tangled
File size audit:
- flag .cs files over 300 lines as split candidates
- flag .cs files over 500 lines as urgent
- suggest the split by responsibility, not by arbitrary regions
Project boundary audit:
- domain should not depend on infrastructure or host projects
- contracts should stay transport-safe
- AppHost should orchestrate, not contain business rules
Folder organization audit:
- check for one major type per file
- check for feature grouping versus giant technical buckets
- check whether endpoints, services, repositories, entities, and contracts are easy to locate
Missing pieces:
- missing contracts project or folder
- missing application/service boundary
- missing test projects
- missing composition root extensions

Explain the score briefly.

Issues Found

Order by impact. For each issue include the exact project/file and the recommended move, split, or create action.

Recommended Target Layout

If a change is needed, show the ideal target shape for this backend.

Migration Steps

Give a safe incremental path that keeps the app working at each step.

Changes

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.
