## Why add is rated Medium

The empty description significantly limits confidence. The tool name 'add' in isolation suggests a Write operation (creating or modifying data).

Given the ambiguity and empty description, Write is the safest classification, but confidence is reduced to 0.45 due to lack of explicit evidence.
