Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% across five parameters, so the schema provides no semantic help. The description never explains what 'shelf' means, what 'summary' vs. 'markdown' should contain, or how 'sources' should be formatted. For a 4-required-param tool, this is a significant gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
