Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must carry the load, and it does for `since`: optional ISO-8601 timestamp with timezone, defaults to 24 hours ago, clamped to the last seven days. `project_id` is only indirectly covered via the tenant-scoping sentence, leaving one parameter thin.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
