Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Only q and continent have schema descriptions; tag, type, limit, and score_mode are largely undocumented, and the tool description does not compensate. The phrase 'ranked matches with scores' hints at score_mode but doesn't explain its enum values or the limit/tag/type filter behaviors. Coverage is only 33%, so agents would have to guess at most parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
