What

Claude Code can now ask for your approval with a message saying it does not know what a tool does yet, so each call needs your approval. For these prompts:

  • there is no option to always allow the tool
  • the automatic safety checker cannot approve the call for you
Why

You may see a prompt for each call to a command Claude Code does not recognise, and you cannot skip it with an always-allow rule.
