Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all parameters (repo, since, until, githubToken, snykToken, async). The description reinforces the purpose of repo and time range but does not add new meaning beyond the schema. The 'async' parameter is not mentioned in the description, but the schema adequately explains it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
