hello targets a single recipient while greet_multiple targets multiple recipients, so the cardinality difference provides some distinction. However, greet_multiple is essentially a batch version of hello, creating overlap if an agent could simply call hello repeatedly.

hello is a bare greeting word while greet_multiple follows a verb+quantifier pattern; both are lowercase snake_case but do not follow a consistent verb_noun convention. The mixed structure is readable but not predictable.

Only two tools exist, which feels thin even for a hello-world server. The second tool is a minor variant rather than a distinct capability, so the set is borderline under-scoped.

The greeting domain is covered for single and multiple recipients, but there is no customization (e.g., formal/informal tone) or additional greeting lifecycle operations. These are minor gaps that an agent can work around.
