Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 2 required parameters, no output schema, no annotations, and a rich sibling set, the description is severely incomplete. It does not explain what an 'external location mapping' is, what session context is needed, or what the result of removal looks like. The agent cannot reliably invoke this tool based on the current definition.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
