Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the baseline is 3. The examples reinforce how domain, min_strength, and limit are combined (e.g. domain="ai-ml", min_strength=0.5, limit=10), but they add no semantic detail the schema lacks, such as whether domain accepts wildcards or what strength measures.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
