Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given a mutation tool with 6 parameters, no output schema, and no annotations, the description is incomplete. It fails to cover all parameter semantics (slug, avatarUrl), doesn't specify the update semantics (partial vs. full replacement), and omits usage guidance. Compared to sibling tools like add_team_account, it doesn't clarify how to achieve specific account changes (replace vs. add).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
