Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate for undocumented parameters. It mentions 'engagement's details' but doesn't explain the three parameters (engagementId, engagement, metadata) or their semantics (e.g., engagementId identifies the target, engagement contains updatable fields). This adds minimal value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
