Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description should compensate by explaining linking_session_id's provenance and role, but it never mentions the parameter. The name and surrounding account-linking context are partially self-explanatory, yet an agent still gets no guidance on where the session ID comes from or how it is used.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
