Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool with no annotations, no output schema, and two undocumented parameters, the description is insufficiently complete. It doesn't explain what a 'tag' represents in this system, what the parameters do, what happens after creation, or how this operation fits within the broader context of tag management (alongside get-tag, update-tag, delete-tag).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
