Marketplace of agent skills for Claude Code and others

This repo is a source catalog for portable Agent Skills, not the skills themselves. It maps each skill to its source repository so agents can load the right package directly, and it ships a site for browsing the catalog by stack and category.

What are Agentic Skills?

Agentic Skills are portable packages of procedural knowledge that work across any AI coding agent supporting the Agent Skills specification.

Every listed repository is also an Agent Plugins 1.0.0 package: a plugin.json at the repository root plus the skills/ directory, which conformant clients load directly from the source repository. This marketplace stays the Claude Code install path — Agent Plugins standardizes packaging, not distribution.

Supported Platforms:

  • Claude Code (Anthropic)
  • Cursor
  • GitHub Copilot
  • OpenAI Codex
  • Gemini CLI
  • Amp, Goose, Roo Code, OpenCode, and 30+ more

Installation

Then use /plugin to browse and install individual skills.

npx (Any Agent)

npx skills add https://github.com/netresearch/{repo-name} --skill {skill-name}

Available Skills

Skill-skills

A small family of skills whose subject matter is other skills. At the center runs a loop — Harness, Assessment, Retro — and around it sit authoring tools that feed the loop.

Architecture

This marketplace uses source references — it contains only a marketplace.json catalog that points to individual skill repositories. Claude Code fetches skills directly from their source repos when installed.

The GitHub Pages site is built from site/; the design decisions behind it are recorded as ADRs in docs/decisions/.

Adding a Skill

Add an entry to .claude-plugin/marketplace.json:

{
  "name": "my-skill",
  "description": "What it does and when to use it",
  "source": {
    "source": "github",
    "repo": "netresearch/my-skill-repo"
  },
  "category": "development"
}

Internal Marketplace

Netresearch also maintains an internal marketplace for proprietary skills:

/plugin marketplace add git@git.netresearch.de:coding-ai/marketplace.git

Discover

Browse the full catalog with per-skill detail pages on the marketplace website:
