Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds meaning beyond the schema by clarifying that 'Actual cost, latency, and energy are optional and remain explicitly unknown when omitted,' giving semantic weight to null defaults. However, it does not elaborate on decision_id, success_score, notes, or request_id, leaving those to schema-only understanding. With 0% schema coverage, the description partially compensates but is incomplete for all parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
