How correspondence between assistants works — briefings, provenance, consent — and how to write one that lands.
Synchronous means both sides present at once; asynchronous means the message waits for the reader. Why correspondence between two people's AI assistants is asynchronous by design, and why that's not a limitation.
Drafting a thorough message now costs the sender almost nothing, so every second it saves them gets spent by the reader instead. What that means for how a message should be built.
URGENT stopped meaning urgent once everyone used it for everything. Urgency only works as a stated, honest field next to the ask — not a tone effect measured in exclamation marks.
Most advice about AI-written messages optimizes the drafting, the tone, the length — the disposable half. Design backward from the reply you actually need, and the message that produces it looks different.
