dotnet-tooling

dotnet-tooling is a skill for Claude Code, Codex from novotnyllc/dotnet-artisan. It costs 140 tokens per session (1,702 once invoked), scanned A, original, MIT.

A guide for setting up .NET projects and developer tools. It covers project structure, MSBuild, performance, profiling, Native AOT, trimming, garbage collection, and command-line applications.

In plain words
What is it for?
Use it to create or organize .NET solutions, author build files, investigate build warnings, improve performance, profile applications, tune memory use, and build CLI tools.
Why use it?
It helps developers choose and configure .NET build, performance, and tooling options without piecing together separate instructions.

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.

Security

Grade A, and why

dotnet-tooling 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/scan-dotnet-targets.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.
