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 and it only partially does: it explains that capability filters by ability (activity/match/manage) and is computed server-side. It does not map the seven enum values (publishActivities, matchAdmin, introduce, draftFromProposal, etc.) to concrete meanings, leaning on the enum literals themselves.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
