Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, so the description must compensate. It identifies that 'sticker' refers to the target sticker and 'keywords' to the new search keywords, but it does not explain formats, replacement vs. appending behavior, or the effect of omitting the optional keywords parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
