Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (no parameters, no output schema), the description is mostly complete: it states the action, scope ('in the project'), and even names the underlying commandlet. However, it could add a note about safety or reversibility, especially since it is a cleanup operation. Still, the minimal context is adequate for a simple tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
