Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It documents all four parameters and notably lists valid channel values (email, slack, discord, console, webhook) that the schema does not enumerate. The 'data' parameter remains vague as 'Optional additional data'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
