WHAT IT DOES

What pwndbg_set_breakpoint does on Pwndbg Lldb

AI agents invoke pwndbg_set_breakpoint 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_set_breakpoint needs a policy

Setting a breakpoint modifies the debugging state of a running or loaded process by inserting a trap/interrupt at a specified location. This is an active operation that affects program execution flow — it's not merely reading data, but triggering a side effect in the debugger/process environment. It falls under Execute as it manipulates the execution context of a binary being debugged.
