Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers what happens (stops machine, flips status), the reversibility, and its relationship to delete_project. It does not mention return values, but that's acceptable given the absence of an output schema. Overall, it is sufficiently complete for the tool's complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
