WHAT IT DOES

What pwndbg_stackf does on Pwndbg Lldb

AI agents invoke pwndbg_stackf 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_stackf needs a policy

The tool belongs to a pwndbg/LLDB MCP server that executes debugger commands. Based on naming convention ('stackf' likely refers to a full stack/frame display command), it probably reads stack frame information. However, since the description is empty and all tools on this server execute pwndbg commands in a live debugger context, the minimum category is Execute. Confidence is low due to empty description.

From the tool's definition Tool name 'pwndbg_stackf' on a server described as exposing pwndbg commands under LLDB for binary analysis and exploit development. Empty description.
