Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description must explain the parameters. It does not: 'y' (presumably pixels) and 'selector' (CSS selector) are left undefined, and there is no explanation of defaults, constraints, or how they interact. This is inadequate for an AI agent.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
