Installation

Add the marketplace

claude plugin marketplace add gao-hongnan/omniagents

Or from inside Claude Code:

/plugin marketplace add gao-hongnan/omniagents

Install plugins

Install individually:

claude plugin install omniagents-python@omniagents
claude plugin install omniagents-typescript@omniagents
claude plugin install omniagents-design-patterns@omniagents
claude plugin install omniagents-writing@omniagents
claude plugin install code-review-graph@omniagents
claude plugin install context7@omniagents

Scope options

Flag	Effect
(none)	User scope — available across all projects
--scope project	Project scope — committed to .claude/, shared
--scope local	Local scope — gitignored, machine-local only

Example — install omniagents-python for the whole team:

claude plugin install omniagents-python@omniagents --scope project

Updating installed plugins

If a plugin is already installed, running claude plugin install ... again is expected to report that it is already installed. Install is not the update path.

Marketplace update only refreshes the catalogue; it does not install plugins that are not already installed.

Refresh the marketplace, then update the installed plugin:

claude plugin marketplace update omniagents
claude plugin update omniagents-python@omniagents
claude plugin update omniagents-typescript@omniagents
claude plugin update omniagents-design-patterns@omniagents
claude plugin update omniagents-writing@omniagents
claude plugin update code-review-graph@omniagents
claude plugin update context7@omniagents

Inside Claude Code, the equivalent commands are:

/plugin marketplace update omniagents
/plugin update omniagents-python@omniagents
/plugin update omniagents-typescript@omniagents
/reload-plugins

Claude Code uses the plugin version as the cache key. Because these plugins set version in each .claude-plugin/plugin.json, maintainers must bump that version whenever published skill contents change. Pushing new commits without a version bump will make updates look current to already-installed users. For fast-moving internal plugins, omit version from both plugin.json and the marketplace entry so Claude Code uses the git commit SHA as the version.

Uninstall

The default scope is user. A bare uninstall command removes from user scope without needing a flag. Add --prune to also drop any orphaned auto-installed dependencies left behind:

claude plugin uninstall omniagents-python@omniagents --prune
claude plugin uninstall omniagents-typescript@omniagents --prune
claude plugin uninstall omniagents-design-patterns@omniagents --prune
claude plugin uninstall omniagents-writing@omniagents --prune
claude plugin uninstall code-review-graph@omniagents --prune
claude plugin uninstall context7@omniagents --prune

If the plugin was installed with a non-default scope, pass the matching --scope flag:

claude plugin uninstall omniagents-python@omniagents --scope project --prune
claude plugin uninstall omniagents-python@omniagents --scope local --prune
