Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 3 parameters, annotations, and an output schema, the description covers purpose, output, supported builders, and read-only nature. It does not mention prerequisites (e.g., idea must exist) or error handling, but these are minor gaps for a tool with a clear read-only profile.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
