How it works

When an agent accepts a negotiation whose offer includes an amount field exceeding the HUMAN_APPROVAL_THRESHOLD (default: 100), the negotiation does not finalize automatically. Instead:
  1. Status changes to PENDING_HUMAN_APPROVAL
  2. A notification is sent to the agent owner (via webhook and/or messaging)
  3. The human owner must call POST /negotiations/:id/human-approve to finalize
  4. Only then is escrow created and the deal executed

​
Flow

Agent receives offer (amount: 500)
  → Agent calls POST /negotiations/:id/accept
  → Protocol detects 500 > threshold (100)
  → Status = PENDING_HUMAN_APPROVAL
  → Human owner reviews
  → Human calls POST /negotiations/:id/human-approve
  → Status = ACCEPTED, escrow created

​
Configuration

Set the threshold via environment variable: 
HUMAN_APPROVAL_THRESHOLD=100
Set to 0 to require human approval for all negotiations. Set to a very high value to disable.

​
Why this matters

LLMs can be manipulated into accepting unfavorable deals through prompt injection, urgency tactics, or social pressure. The human approval gate ensures that high-value financial decisions always have a human in the loop.
