Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The schema is rich with aliases and enums, but the description leaves gaps: it does not explain why memory_id is optional despite referring to 'stored memories,' nor the distinction between session_id and memory_id contexts. The presence of an output schema and full parameter docs reduces the severity, but the ambiguous optionality is a meaningful gap.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
