DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

 | `-y, --yes`           | Accept a command the plugin's marketplace declares, without the confirmation prompt: the command that produces a plugin with a [`command` source](/docs/en/plugin-marketplaces#command-sources), or the [`headersHelper`](/docs/en/plugin-marketplaces#authenticate-archive-downloads) that authenticates an archive download. Accepting a `headersHelper` requires Claude Code v2.1.238 or later. Claude Code still prints the command first. Required when stdin or stdout isn't a TTY. Has no effect inside a Claude Code session, so run the command from your own terminal |         |

+<Note>
+  Claude Code resolves a bare plugin name against your installed plugins. When installed plugins from different marketplaces share the name, Claude Code refuses the update and lists the qualified `plugin-name@marketplace-name` commands to run instead. Before v2.1.246, Claude Code accepted only the qualified form and rejected a bare name as not found.
