Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, meaning all three parameters are undocumented in the schema. The description adds no semantic information about 'graph_id', 'from', or 'to'—it doesn't explain what these represent (e.g., node IDs, names), their formats, or constraints. Since the description fails to compensate for the schema's lack of documentation, the score remains low.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
