Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, with the 'topic' parameter clearly documented as 'Topic to search for (e.g., "ped", "vehicle", "weapon").' The description doesn't add any additional meaning beyond this, such as examples of valid topics or search behavior. Since the schema does the heavy lifting, the baseline score of 3 is appropriate, as the description doesn't compensate but also doesn't detract.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
