ReasonFlow
autonomous inbox agent.
Classify the message, retrieve its context and draft the response. Route uncertain decisions to a person before dispatch.
The message pauses at the review gate.
SIMULATED CONFIDENCENOT A MODEL SCORE
A message arrives. The system finds context before it acts.
The context leaves room for doubt.
Pause here for a person’s decision.
The draft clears the routing gate.
Continue toward dispatch.
02 / THE PROBLEM
A plausible reply is not enough to act on an inbox. The agent needs the context behind the message and a deliberate place to pause when the decision is uncertain.
03 / SYSTEM MODEL
Email → classify → retrieve → decide → execute → draft → review → dispatch
04 / ARCHITECTURE
Human review is a route through the system—not a workaround when the model gets stuck.

05 / ENGINEERING DECISIONS
Make uncertainty part of the routing logic. Retrieved context supports the draft; the review gate determines whether it proceeds or waits for a person.
06 / FAILURE SURFACES & TRADEOFFS
Confidence is a useful routing signal, not evidence that a response is correct. Review adds waiting time, but creates a clear point to intercept uncertain actions.
