agent-signal

Each tool has a completely distinct function: numeric addition, text echo, and time retrieval. There is no overlap or ambiguity between them.

The names are short and readable, but they mix verb patterns (add, echo) with a noun phrase (server_time). There is no consistent verb_noun or other uniform convention, though the inconsistency is minor.

With only 3 tools, the set is minimal but appropriate for a simple utility server. It is on the low end of typical scope but not thin enough to be problematic.

The tools cover basic utility operations without an obvious domain requiring more (e.g., no CRUD expected). The only minor gap is that functionally related operations (e.g., subtraction or formatting) are absent, but the set is internally coherent.
