Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already documents both 'input' and 'policy', so baseline is 3. The description adds meaningful context by naming Flesch-Kincaid reading level, brand voice violations, and GDPR/COPPA markers, which gives the agent a clearer understanding of what the policy object and output will address.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
