Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has one required parameter, no output schema, and no annotations, the description is incomplete. It does not explain what 'apply styles' entails, which part of Figma is affected (selection, whole document), or the expected format of the markdown file. An agent may not have enough context to use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
