What

Before running a slash command, Claude Code now consults a policy value attached to the command entry and can refuse it, showing the reason. Commands with no such policy value attached still run as before.

Details
  • The policy value is supplied by the server on each command entry; absent one, the command is allowed.
  • Refusals emit telemetry that separates a stale command list from an active denial.

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