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 slug, version, and endpoint_id. The description adds that the tool reads 'by slug or id' and repeats the version omitting behavior, but it doesn't meaningfully enrich the parameter semantics beyond what the schema already provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
