The tools are highly distinct: one searches by various criteria, one lists groups for a specific user, one detects inactivity, and one performs complex CSV cross-validation. Each serves a very clear and non-overlapping purpose.

The tools consistently follow a clear action_subject pattern using Spanish verbs and nouns (e.g., 'buscar_usuario', 'listar_grupos_de_usuario'). The naming conventions are predictable and highly readable across the entire set.

For a directory server, four tools cover essential management and auditing functions effectively. While a few more granular retrieval tools might be useful, the current count is well-scoped to the functions presented.

The current set is almost entirely focused on read-only operations and auditing. There is a critical absence of basic user lifecycle management functions, such as creating, deleting, or modifying user attributes/passwords.
