Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one required parameter, no output schema, no nested objects), the brief description is largely sufficient for an AI agent to understand its basic use. However, it could be slightly more explicit about the scope of 'unlocks' (e.g., whether it includes features, items, or abilities) to achieve full completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
