Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a no-parameter, read-only list tool, the description is complete. It names the output fields (website_id, URL, platform, autopilot status), explains why the output matters for other tools, and gives sequencing guidance. With no output schema, this description sufficiently covers what an agent needs to know to call the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
