The four tools have mostly distinct purposes: whisper creates a message, listen reads messages, forget deletes a message, and rest is a closing ritual. There is mild potential overlap between whisper and rest because both can leave text, but rest is clearly framed as a separate end-of-session action.

All tool names are single lowercase verbs in a consistent imperative style: whisper, listen, rest, forget. There is no mixing of casing or naming patterns.

Four tools is well-scoped for a small, poetic tree-hollow server. Each operation maps to a clear interaction without unnecessary surface area.

The surface covers creating, reading, deleting, and a closing ritual, which fits the domain well. An explicit update/edit operation is absent, but the delete-and-rewrite pattern is a reasonable workaround.
