Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the schema provides no parameter documentation. The description mentions no parameters at all, failing to explain what 'filename' and 'category' mean, their formats, or how they interact. For a tool with 2 parameters (one required), this leaves significant gaps in understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
