What
Claude Code supports installing plugins (bundles of extra commands and tools) via deep links, special links that trigger an install when clicked. A new control, the tengu_amber_tollgate gate, can now block these deep-link installs entirely. When blocked, instead of running or asking for confirmation, Claude Code shows: "Plugin install links are turned off. To install, type /plugin install yourself."
Why
This gives a way to disable one-click plugin installation from links, requiring users to explicitly run /plugin install themselves instead.
The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
