Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (one parameter, no output schema), the description is minimally adequate. However, it lacks any context about return format, pagination, or edge cases, and the presence of a sibling tool with similar scope (get_team_recent_files) introduces ambiguity that the description does not resolve.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
