What
If a plugin marketplace entry installs itself by running a command on your machine, install and update now print that command and ask "Run this command now? [y/N]". Acceptance is remembered per exact command string, so a changed command forces a fresh confirmation with a warning.
Details
-y/--yes is refused when the CLI is itself running inside another Claude Code session.
In a non-interactive terminal the command is only printed, never accepted.
Link mode for these plugins is refused on Windows.
Usage
claude plugin install <name>@<marketplace>
Evidence
Not an interactive terminal, so the command was only displayed, not accepted.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
