Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description compensates: it defines payload as the structure from export_storyline (schema_version, graph, profile_schema, top-level fields) and explains override_agent_name rebinding with the agent existence condition. Both parameters are semantically explained.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
