dotnet-ai-toolkit

dotnet-ai-toolkit is a plugin for Claude Code from StefanTheCode/dotnet-ai-toolkit. Its manifest loads nothing; the 49 skills it bundles cost 5,371 tokens per session together, scanned A, original, MIT.

A toolkit of coding skills and specialist agents for .NET, Microsoft’s application-development platform, including C# and older .NET Framework projects. It covers APIs, database access, testing, authentication, monitoring, architecture, code review, and security.

In plain words
What is it for?
Use it to review .NET architecture and code, optimize Entity Framework Core database queries, create Minimal APIs, write xUnit and Testcontainers tests, configure JWT authentication and OpenTelemetry, audit security, and maintain legacy .NET Framework or WinForms code.
Why use it?
It helps developers handle common .NET development and maintenance tasks across both modern applications and older codebases.

Security

Grade A, and why

dotnet-ai-toolkit 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 yesterday.

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 installs

The manifest is a name and a version. 49 skills travel with it, and installing the plugin installs all of them — 5,371 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside marketplace.json#dotnet-ai-toolkit 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.

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.
