What
Claude Code can add tools partway through a conversation. Sometimes those late additions are rejected. When that happens, Claude Code still falls back to announcing the tools through tool search, which is how Claude finds and loads tools that are held back until needed. That fallback has not changed.
What is different is that, in some cases, Claude Code now also sends a usage report marking the rejection as a retry. Previously it only sent its existing report about the rejected addition.
Why
The extra report hints that a retry path for rejected tool additions is being prepared. For now, nothing changes in what you see or in how the tools load.
