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, 0% schema description coverage, and no output schema, the description is insufficiently complete. It doesn't address behavioral aspects (permissions, reversibility, side effects), parameter details, or expected outcomes. Given the complexity of WordPress plugin management and the complete lack of structured documentation, the description should provide more contextual information.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
