Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the basic purpose, parameters, and return type, which is adequate for a simple visualization tool. However, it omits usage guidance, selection requirements beyond the phrase 'selected curves', and explicit safety/side-effect information. The output schema existing reduces the need to document return structure, but the missing usage and selection context leave notable gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
