Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description needs to explain return values, and it does by mentioning 'authenticated:true', 'pending[]', and 'connect_url'. It also covers two main scenarios. While not exhaustive, it is sufficient for a simple read-only status tool, especially given the annotations indicate non-destructive, idempotent behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
