Overview
What It Does
Sendmux Token Efficient Usage packages a focused communication workflow for an AI agent. Choose the cheapest correct Sendmux surface and call. Use whenever a Sendmux task could be done through MCP, the sendmux CLI, an SDK, or direct HTTP and the user needs low-token, low-round-trip usage: batch sends, mailbox search/count/batch reads, sync deltas, cursor pagination, ETags, conditional requests, idempotency keys, attachment file transfer, or avoiding broad mailbox/log fetches. It is best suited to users who can review the resulting actions and provide only the accounts, files, or command access needed for the task. It is not a substitute for human approval on destructive, financial, security-sensitive, or public-facing actions.
