Source Intelligence

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.

Plugins Notable

Plugin install and update take -y to skip the command confirmation, but not inside a session.

-y--yesclaude plugin installclaude plugin update
What

Both subcommands accept -y/--yes, which accepts a plugin whose install method is a command declared by its marketplace without showing the interactive confirmation. It is required when stdin or stdout is not a terminal, and it is refused with an explicit message if you run it from inside a Claude Code session.

Usage
claude plugin install my-plugin@my-marketplace -y
Evidence

For a plugin installed by running a marketplace-declared command: accept the displayed command without the confirmation prompt (required when stdin or stdout is not a TTY)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
