Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 33% (only 'query' has a description). The tool description adds meaning by clarifying that queries can be names, categories, platforms, instruments, or rule preferences, which helps interpret the 'query' parameter. However, it does not explain 'limit' or 'category' beyond what the schema already provides, so compensation is partial.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
