Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the output schema exists and the parameter schema is fully documented, the description covers the essential contextual aspects: what, when, where, and required permissions. It lacks detail on idempotency or whether existing capsules are overwritten, but overall it is complete for a simple record tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
