Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must compensate, and it does for three of four parameters: from/to filtering, exercise_slugs filtering, and limit defaults/caps (30 days, 20, max 100). It does not specify the date string format for from/to nor the slug format, leaving a small gap on the wire format.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
