.NET Agent Skills

English | 中文

[!NOTE] Fork notice: This repository is a fork of the official dotnet/skills repository. All skills, plugins, and tooling are Copyright © the .NET Team at Microsoft, licensed under the MIT license. The only change made in this fork is a DeepSeek Harness (DSH) packaging layer so the full catalog can be installed as a DSH plugin — see the DSH section below. In the other install methods below, replace dotnet/skills with flyneth/dotnet-skills to install this fork's version. Everything else is unchanged upstream content.

This repository contains the .NET team's curated set of portable skills and host-specific custom agents for coding agents. For information about the Agent Skills standard, see agentskills.io.

[!TIP] Compare skill value: Open the Skill Value dashboard See token use, elapsed time, activation, and not-passed rates by plugin, skill, executor model, and judge model.

Plugin support is component-specific:

• Skills and MCP servers are the portable component types defined by Agent Plugins 1.0.
• Files under agents/*.agent.md use GitHub Copilot custom-agent conventions. They are not installed as native OpenAI Codex agents.
• Native Codex agents use .codex/agents/*.toml. This repository does not currently ship them because Codex plugin installation does not place agent files in those discovery locations.

What's Included

Agentic Workflows

Reusable GitHub Agentic Workflows are published under agentic-workflows/. Install the complete collection with gh aw add-wizard dotnet/skills/agentic-workflows@main, or install an individual package using the command in its README.

DeepSeek Harness (DSH)

This fork ships an official-spec DeepSeek Harness bundle at the repository root — package.json declares dsh.bundle, cordis.patch.yml mounts the entry, and index.mjs bridges the skill packs onto ctx.skills — packaging all 17 plugins, 106 .NET skills in total, as one installable DSH bundle.

Option 1 · npm (recommended)

dsh plugin --profile <name> add dotnet-skills

<name> is the target profile; for the default web profile use --profile web:

dsh plugin --profile web add dotnet-skills

Option 2 · dsh-market (one-click, once listed)

Once listed in the dsh-market catalog: open the plugin market in the web UI, search dotnet-skills, and install with one click.

Option 3 · from this repository (no npm)

dsh plugin --profile <name> add github:flyneth/dotnet-skills

Same profile rule applies — --profile web for the default web profile.

• After installation, all skills are available in every profile that lists the bundle.
• Compatibility: "engines": { "dsh": ">=0.2.0-rc.2" }.
• Skills are read straight from plugins/<plugin>/skills/<skill>/SKILL.md at load time — no snapshot, so upstream updates flow through automatically.
