claude-code - 💡(How to fix) Fix [DOCS] Plugin docs missing autocomplete for `/plugin` arguments: subcommands, installed plugin names, and marketplace plugins

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://code.claude.com/docs/en/discover-plugins

Section/Topic

The /plugin command usage section (throughout the page). The interactive-mode slash-command reference could also benefit from a cross-reference.

Current Documentation

The discover-plugins page documents /plugin subcommands (install, enable, disable, uninstall, marketplace add/remove/update/list) and the /plugin tabbed interface, but never mentions Tab-based autocomplete for /plugin arguments.

For example, the "Install plugins" section shows:

/plugin install plugin-name@marketplace-name

And the "Manage installed plugins" section shows:

/plugin disable plugin-name@marketplace-name /plugin enable plugin-name@marketplace-name /plugin uninstall plugin-name@marketplace-name

The interactive-mode page documents Tab autocomplete for ! shell commands and @ file references, but does not mention slash-command argument autocomplete.

What's Wrong or Missing?

As of v2.1.157, /plugin supports Tab-based argument autocomplete:

• Typing /plugin and pressing Tab shows available subcommands (install, enable, disable, uninstall, marketplace, etc.)
• Typing /plugin install and pressing Tab shows installed plugin names
• Typing /plugin install with a partial plugin name and pressing Tab shows plugins from known marketplaces

This autocomplete behavior is completely undocumented. The discover-plugins page shows all the subcommand syntaxes but never tells users they can Tab-complete through them. Users may type commands manually or navigate the interactive UI without knowing the CLI has completion support.

Suggested Improvement

Add a short note after the /plugin command table or in the interactive-mode slash-command section explaining that pressing Tab after /plugin shows available subcommands, and that pressing Tab after a subcommand (like install ) shows matching plugin names from installed and known-marketplace plugins.

For example, add after the "Manage installed plugins" section:

> **Tip:** Press Tab after `/plugin` to see available subcommands. After typing a subcommand like `/plugin install`, press Tab again to autocomplete plugin names from your installed plugins and known marketplaces.

Impact

Medium - Makes feature difficult to understand

Additional Context

This autocomplete was added in v2.1.157. The discover-plugins page (https://code.claude.com/docs/en/discover-plugins) is the primary reference for /plugin commands and should document this behavior. The interactive-mode page (https://code.claude.com/docs/en/interactive-mode) already documents Tab autocomplete for ! shell commands and @ file references; adding slash-command argument autocomplete would make the autocomplete coverage complete.
