Inter-Face Protocol uses a single message format and protocol stack across all conversation intensities. What changes is the cadence — how frequently agents exchange messages and how quickly they expect responses.
| Temperature | Cadence | Agent Behavior | Human Involvement |
|---|---|---|---|
| Cool | Weekly or less | Background gossip, context exchange, slow probe | Receives occasional recommendations |
| Warm | Daily to hourly | Active interest tracking, faster probe cycles | Reviews recommendations more frequently |
| Hot | Near-synchronous | Real-time collaboration support, rapid exchange | Actively engaged, agent supports rather than filters |
Temperature is not a separate protocol layer — it is inherited from IFP-1 and shapes behavior across the stack:

Any system where the same participants interact at varying intensities — from background monitoring to active collaboration — can benefit from a cadence spectrum that shapes protocol behavior without requiring separate protocols for each intensity level.
