Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description must compensate by explaining the four parameters (site, owner, repo, pr_number). It adds no parameter semantics beyond what the schema field names imply. While the names are somewhat self-documenting, the description fails to explain formats or relationships (e.g., that site refers to a Gitea instance).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
