Bundling Claude Plugins with Your Pants Plugin

If you're a Pants plugin author, you can bundle recommended Claude Code plugins with your plugin.

Create a bundled_claude_plugins.py file in your plugin package:

# src/your_plugin/bundled_claude_plugins.py

# Marketplaces to add before installing plugins (GitHub repos, git URLs, etc.)
# These are automatically added when users run --include-bundled
BUNDLED_MARKETPLACES = [
    "anthropics/claude-code",  # GitHub owner/repo format
    # "https://gitlab.com/company/plugins.git",  # Full git URL also supported
]

BUNDLED_CLAUDE_PLUGINS = [
    {
        "plugin": "github",
        "marketplace": "claude-plugins-official",
        "scope": "project",  # optional
        "description": "GitHub integration",  # optional
    },
    {
        "plugin": "commit-commands",
        "marketplace": "anthropics-claude-code",  # This marketplace is auto-added above
    },
]

When users install your plugin and run pants claude-install --include-bundled :::

1. Any bundled marketplaces are automatically added
2. Then the bundled plugins are installed from those marketplaces
