dotnet-artisan

Comprehensive .NET development skills for modern C#, ASP.NET, MAUI, Blazor, and cloud-native applications

Overview

dotnet-artisan provides 9 skills (2 routing + 7 domain) and 14 specialist agents for .NET development. It is compatible with Claude Code, GitHub Copilot CLI, and OpenAI Codex. Claude and Copilot consume the plugin manifests directly; Codex now has a first-class plugin manifest plus marketplace metadata, while still keeping the older skill-centric metadata as a direct-install compatibility layer. Specialist agents/*.md are currently used by Claude/Copilot flows; Codex routes through the skills/* surface.

The plugin covers the full breadth of the .NET ecosystem:

• Modern C# patterns, async/await, dependency injection, and source generators
• ASP.NET Core APIs, Blazor, MAUI, Uno Platform, WinUI, and WPF
• Entity Framework Core, data access strategies, and serialization
• Testing with xUnit, integration testing, Playwright, and snapshot testing
• CI/CD for GitHub Actions and Azure DevOps
• Native AOT, trimming, performance profiling, and benchmarking
• Security, packaging, documentation, and release management

Installation

Claude Code

From within Claude Code, run:

/plugin marketplace add novotnyllc/dotnet-artisan
/plugin install dotnet-artisan@dotnet-artisan

Once installed, Claude Code automatically loads relevant skills based on your questions about .NET development.

OpenCode (oh-my-opencode)

OpenCode supports Claude Code plugins. Install with Claude Code first using:

/plugin marketplace add novotnyllc/dotnet-artisan
/plugin install dotnet-artisan@dotnet-artisan

Then set this in ~/.config/opencode/oh-my-opencode.json:

{
  "claude_code": {
    "plugins": true
  }
}

GitHub Copilot CLI

Install as a Copilot plugin:

copilot plugin marketplace add novotnyllc/dotnet-artisan
copilot plugin install dotnet-artisan@dotnet-artisan

The flat skills/<skill-name>/ layout remains compatible with Copilot's one-level-deep skill scanning.

OpenAI Codex

Codex plugin-aware surfaces discover this repo through .codex-plugin/plugin.json and .agents/plugins/marketplace.json.

The repo also keeps .agents/openai.yaml and skills/<skill-name>/agents/openai.yaml as a compatibility path for direct skill installs and local ~/.codex/skills/ sync workflows.

For direct skill-centric installs, use:

$skill-installer install https://github.com/novotnyllc/dotnet-artisan

You can also sync skill directories into ~/.codex/skills/.

Root agents/*.md specialist definitions are not yet first-class Codex skills, so Codex still routes through the broad skill layer.

Provider Support Matrix

Provider	Primary surface	Status
Claude Code	.claude-plugin/plugin.json + skills/* + agents/*.md + hooks + MCP	Supported
GitHub Copilot CLI	.claude-plugin/plugin.json + skills/* + agents/*.md	Supported
OpenAI Codex	.codex-plugin/plugin.json + .agents/plugins/marketplace.json + skills/*	Supported

Compatibility is validated in CI with structural smoke checks via scripts/run-agent-routing-smoke.py --provider claude,codex,copilot.

Skill Catalog

The plugin organizes 9 skills in a flat directory layout (skills/<skill-name>/SKILL.md), backed by 159 reference files (~62K lines) of deep-dive guidance loaded on demand. Each skill follows the Agent Skills open standard with structured frontmatter and progressive disclosure — SKILL.md routing tables point to references/*.md companion files that Claude reads only when relevant.
