Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is minimally adequate for a simple zero-parameter stop action, but it lacks lifecycle context (e.g., what a session is, whether logs persist, or when it should be called). Given the sibling tool named remote_spy_start, the role is inferable, but the description itself is somewhat sparse.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
