WHAT IT DOES

What pwndbg_mprotect does on Pwndbg Lldb

AI agents invoke pwndbg_mprotect to trigger actions in Pwndbg Lldb. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why pwndbg_mprotect needs a policy

mprotect modifies memory page permissions (read/write/execute) on a live process, which is an active execution-side effect with potentially significant consequences. The description is empty, lowering confidence, but the name strongly implies triggering memory protection changes in a debugged binary — a common exploit development primitive.

From the tool's definition Tool name 'pwndbg_mprotect' suggests invocation of the mprotect system call or related debugging command, which changes memory protection flags on a running process.
