## What it is
Agent Plugins is an open, vendor-neutral specification (v1.0.0) defining a portable package format for bundling Agent Skills and MCP servers into distributable plugins for AI agent clients. The repository hosts the versioned spec, JSON schemas, and governance documents.

## Use cases
- package agent skills into a distributable plugin
- bundle MCP servers in a portable format
- make one plugin work across multiple AI agent clients
- implement a client that loads agent plugins
- avoid rewriting plugins for each agent client

## When to choose
- you author agent extensions and want one portable package format
- you build an agent client and want standards-based plugin discovery and loading
- you need a vendor-neutral interoperability floor for skills and MCP servers

## When to avoid
- you need a runtime or executable tool rather than a specification
- you need client-specific features like permissions, installation, or UX that the spec leaves to clients
- you require a mature ecosystem with many published plugins already

## Facets
- artifact type: learning-resource
- maturity: active

- domain: large-language-models, developer-tools, apis
- platform: cross-platform
