Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 25% (2 of 8 parameters have descriptions: headUrl and headType). The description adds no parameter semantics beyond the schema. The tool name suggests 'by file' but the schema includes headUrl (online URL) and headType (person or web3), which are partially described. The other 6 parameters (ct0, tweet, apiKey, proxyUrl, resFormat, auth_token) are completely undocumented, and the description does not compensate for this gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
