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

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.

| agent-harness | agent-harness-skill | Agent Skill for bootstrapping, verifying, and enforcing agent-harness infrastructure in repositories |
| automated-assessment | automated-assessment-skill | Systematic project assessment with scripted + LLM verification |
| retro | retro-skill | LLM-driven session retrospection: detects friction and materializes learnings into user memory, project rules, skill PRs, checkpoints, or harness artifacts. Includes /retro outcome and /retro audit modes |
| agent-rules | agent-rules-skill | Generate AGENTS.md with CI rules, architecture, ADRs extraction |
| skill-repo | skill-repo-skill | Skill repository structure, validation, and distribution |
Host-side tooling (not Agent Skills themselves, but part of the same family):
- composer-agent-skill-plugin — Composer plugin that pulls Agent Skills into PHP projects.
- node-agent-skill-coordinator — Discovers skills shipped via npm packages and registers them in the project's
AGENTS.md.

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/.

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"
}
