Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple 0-parameter read-only tool, the description gives a clear summary of the returned fields, which is adequate for basic invocation. However, there is no output schema, no annotations, and no mention of return format, prerequisites, or error behavior. It is a minimal viable description but leaves some context gaps (e.g., whether this is for the current binary).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
