Plugins

Plugins are Agent Plugins packages: a bundle of skills and MCP servers that installs as one unit. Aster reads the format unchanged. A plugin’s MCP servers appear under names like <plugin>/<server>, and its skills appear in /skills.

aster plugins add owner/repo | ./dir [-p] [--plugin name] [--all] [-y] [-l] [--force]
aster plugins list [-p|-g]
aster plugins remove name [--purge] [-y]
aster plugins validate [./dir]

-p installs into the project instead of globally. --purge on remove also deletes the plugin’s cached skills and servers.

Where they land

Installed plugins live under the skills root next to regular skills, and their server contributions merge into the MCP catalog. Names aster.yaml already defines win a collision; a plugin only fills gaps.
