Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with one parameter and no output schema, the description is adequate but leaves gaps. It does not clarify whether the deletion is reversible, if there are any prerequisites (e.g., profile must exist), or what the return value looks like. Given the low complexity, a slightly more detailed description would be expected, so a 3 is appropriate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
