Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has one parameter, an output schema, and annotations all available, but the description is minimal. It explains the limitation but doesn't tell the agent what to expect as output, how to specify the device, or why the tool exists (i.e., why not just call clear_logs on the router). Given the explanatory nature, the description should clarify that it's a no-op or query that returns a reason, which is missing. The output schema exists, so return format might be redundant, but the purpose context is insufficient. The tool is relatively simple, so a bit more description would make it complete; currently it's incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
