Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers scope and parameter semantics, and the output schema handles return values. However, it lacks guidance on choosing between search_keyword and search_semantic, and does not clarify exact matching behavior (e.g., phrase matching, substring, case sensitivity). Given the tool's simplicity, this is adequate but not complete for an agent to use it optimally.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
