Settings versus the permission boundaries themselves
None of the settings on this page affect what tCode is fundamentally allowed to do on your behalf without your knowledge; they change how it behaves within the boundaries already described in Permissions and safety, never the boundaries themselves.
Turning on auto-approve for a specific tool, for instance, changes whether you are asked before that tool runs. It never changes whether the tool-level checks described in Security still apply underneath, those apply unconditionally regardless of any setting here.
See Security for what stays true no matter how any of these settings are configured, and Permissions and safety for the boundary these settings operate inside of.
This distinction matters most for anyone evaluating whether tCode's settings are safe to configure aggressively: turning on every available auto-approve does make sessions faster, but it never expands what tCode is capable of doing, only how much it asks before doing it.
The security-relevant checks, what tCode's own configuration directory blocks, what the permission prompt warns about for unusual destinations, run identically whether every setting on this page is at its most permissive or its most conservative.
