Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a read-only status tool with a single optional parameter and no output schema, the description is reasonably complete. It names the resource (IPsec SAs), the phases (1/2), the data type (state), and the parameter. However, given the large sibling set with similar status tools (gateway_status, interface_status, states_table), more clarity on what distinguishes this output (e.g., tunnel-specific SA details vs general gateway health) would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
