# Plugin systems

Plugin support is a family of independent claims covering portable manifests, native extensions, packaged skills, packaged MCP, distribution, isolation, and vendor extensions.

- HTML: https://canmyagentuse.com/features/plugins
- JSON: https://canmyagentuse.com/api/v1/features/plugins.json
- Markdown: https://canmyagentuse.com/features/plugins.md

Terminology basis: Catalog grouping. This organizes related compatibility questions and is not itself a support claim.

“Supports plugins” is not a sufficient compatibility claim. A product-native extension, a portable Agent Plugins package, a packaged skill, and a marketplace install can have different formats, trust boundaries, and lifecycle behavior.

This family derives progress from independently evidenced atomic capabilities.

## Atomic capabilities

- [Agent Plugins failure isolation](/features/agent-plugin-failure-isolation.md) — Reject invalid components narrowly without disabling valid components in the same package.
- [Agent Plugins packaged MCP](/features/agent-plugin-mcp.md) — Load MCP server configuration contained in an Agent Plugins package.
- [Agent Plugins packaged skills](/features/agent-plugin-skills.md) — Load portable Agent Skills contained in an Agent Plugins package.
- [Agent Plugins portable manifest](/features/agent-plugin-core.md) — Load the published portable plugin.json manifest and its core components.
- [Native plugin system](/features/native-plugins.md) — Install and load a product-specific extension package.
- [Plugin marketplace](/features/plugin-marketplace.md) — Discover and install extensions through a documented registry or marketplace.
- [Plugin vendor extensions](/features/plugin-vendor-extensions.md) — Preserve namespaced host-specific behavior without representing it as portable core support.

## Current family progress by product

Family support is derived from atomic child records. No umbrella compatibility value is authored.
