Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a transfer tool with no annotations, the description is severely incomplete. It fails to mention preconditions (e.g., checking balances with get_wallet_token_balance), postconditions, or error states. The output schema exists but is not explained, leaving the agent without a full picture.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
