Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the transparency burden. It discloses two behavioral traits: the table is 'padded' and the first row is treated as a header. It also notes it 'Runs on smart-tools.xyz', which is context but not critical. It does not mention whether the operation is read-only, possible side effects, or error handling, but given the tool's simple nature, this is acceptable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
