dsh_inbox_status reads/polls session state while dsh_inbox_deliver writes/sends a prompt; there is no overlap in their actions. An agent can easily choose the right tool based on whether it needs to observe or act.

Both tools share the clear dsh_inbox_ prefix and use snake_case, so they are instantly recognizable as part of one server. The minor deviation is that one name uses a noun (status) and the other uses a verb (deliver), rather than a uniform verb_noun pattern.

Two tools is at the low end of the acceptable range and feels thin for a general MCP surface. For the narrow status-and-deliver purpose the count is reasonable, but it is borderline rather than solidly well-scoped.

The core poll-and-deliver loop is covered: status tells whether the session is ready or busy, and deliver handles the different queueing modes. Mino gaps exist around inspecting queued messages or listing multiple sessions, but agents can generally work around these.
