Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 71%, with expected_revision, reason, claim_id, team_id and validity all self-documented in the schema. The description's 'read its current revision first' usefully explains the expected_revision workflow, but it says nothing about action enum semantics or when validity/value are appropriate. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
