Denied tools get a new marker when they are withdrawn

When tools added later in a session are withdrawn because they were denied, Claude Code marks this, behind a switch that is off by default

Unclear It is not clear what the marker changes in what the model is told.

What

Some tools are made available to the model partway through a session rather than at the start. When Claude Code withdraws these tools because they were denied, it now adds a marker saying so. This sits behind a remotely controlled switch that is off unless it is switched on remotely.

Why

This may change how the model is told that a tool was denied.
