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, no output schema, and a complex nested parameter structure, the description is inadequate. It doesn't address key questions about validation behavior, error handling, permission requirements, or what constitutes a successful update. The agent would struggle to use this tool correctly without trial and error.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
