Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must explain parameters. The single parameter 'node_name' is partially clarified by 'optionally filtered to one node', which links the parameter to its purpose. However, it doesn't explain the expected format (e.g., node ID vs name) or behavior if omitted.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
