Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, no annotations, and sibling tools with overlapping purposes, the description fails to provide complete context. It does not explain what the tool returns, side effects, or how it differs from related tools like add_ticket_comment, leaving gaps for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
