Install Dotnet Tooling

skills CLI
$ npx skills add novotnyllc/dotnet-artisan --skill dotnet-tooling -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install novotnyllc/dotnet-artisan dotnet-tooling --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/novotnyllc/dotnet-artisan.git skills-src && mkdir -p .claude/skills && cp -r skills-src/plugins/dotnet-artisan/skills/dotnet-tooling .claude/skills/dotnet-tooling && rm -rf skills-src

Use ~/.claude/skills/ instead of .claude/skills for a personal install. The folder must contain SKILL.md.

What it does

Dotnet Tooling is an agent skill from novotnyllc/dotnet-artisan. Manages .NET SDK installation (dotnet-install, workloads), project setup (.slnx, Directory.Build.props, CPM), MSBuild authoring, build optimization, performance (Span, ArrayPool, stackalloc), profiling (dotnet-counters, dotnet-trace), Native AOT/trimming, GC tuning, CLI apps (System.CommandLine, Spectre.Console, Terminal.Gui), ILSpy decompilation, VS Code debug config (launch.json, coreclr, remote), C LSP (csharp-ls, OmniSharp), and version detection/upgrade. Spans 34 topic areas. Do not use for UI implementation…

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 39 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/add-analyzers.md` and `references/aot-architecture.md`).

It sits in Development. It works with .NET, C# and Visual Studio Code. The repository describes itself as: Comprehensive .NET development skills for modern C and .NET. The licence is MIT.

When your agent uses it

  • UI implementation
  • API security design

Example prompts

  • “Use the dotnet-tooling skill to manage .NET SDK installation (dotnet-install, workloads), project setup (.slnx, Directory.Build.props, CPM), MSBuild…”
  • “/dotnet-tooling”

Requirements

  • Docker

What it can do on your machine

Read from SKILL.md and the folder at commit de192c1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/, which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Dotnet Tooling loads about 1.8k tokens when it runs, and up to ~132k if it reads all its reference files. Until then it costs about 140 tokens; SKILL.md has 611 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~140
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~132k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Questions about Dotnet Tooling

What does Dotnet Tooling do?

Manages .NET SDK installation (dotnet-install, workloads), project setup (.slnx, Directory.Build.props, CPM), MSBuild authoring, build optimization, performance (Span, ArrayPool, stackalloc)…. Dotnet Tooling is an agent skill from novotnyllc/dotnet-artisan.json, coreclr, remote), C LSP (csharp-ls, OmniSharp), and version detection/upgrade.

When should I use Dotnet Tooling?

Dotnet Tooling fits situations like: UI implementation; API security design.

How do I install Dotnet Tooling in Claude Code?

Run `npx skills add novotnyllc/dotnet-artisan --skill dotnet-tooling -a claude-code`. Or copy the skill folder (plugins/dotnet-artisan/skills/dotnet-tooling in novotnyllc/dotnet-artisan) into .claude/skills/dotnet-tooling in your project. Claude Code loads it when a task matches its description.

How do I install Dotnet Tooling in Codex?

Run `npx skills add novotnyllc/dotnet-artisan --skill dotnet-tooling -a codex`. Or copy the skill folder (plugins/dotnet-artisan/skills/dotnet-tooling in novotnyllc/dotnet-artisan) into .agents/skills/dotnet-tooling in your project. Codex loads it when a task matches its description.

Can I use Dotnet Tooling in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add novotnyllc/dotnet-artisan --skill dotnet-tooling -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/dotnet-tooling, .gemini/skills/dotnet-tooling, .github/skills/dotnet-tooling and .opencode/skills/dotnet-tooling in your project.

What does Dotnet Tooling need to run?

SKILL.md names no scripts, command-line tools or credentials: Dotnet Tooling is instructions for the agent only. Our summary lists: Docker.

Does Dotnet Tooling access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Dotnet Tooling safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Dotnet Tooling use?

Dotnet Tooling is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Dotnet Tooling use?

About 1.8k tokens (SKILL.md is roughly 7.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 130k tokens, read only when the agent opens those files.

What are the alternatives to Dotnet Tooling?

Skills that share tags, products or a category with Dotnet Tooling: Release Roslynator (dotnet/roslynator, 3.5k stars), Maui Hot Reload Diagnostics (davidortinau/maui-skills, 175 stars), Speckit Constitution (WeihanLi/WeihanLi.Common, 242 stars) and Analyzing .NET Performance (dotnet/skills, 5.6k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Dotnet Tooling?

novotnyllc (a GitHub organization) maintains it in novotnyllc/dotnet-artisan, which has 233 GitHub stars. The repository holds 9 skills in this directory. The repository was last updated on October 8, 2026.
