How to Set Up an Approval Workflow

Approval workflows are how agents stay fast without spending unreviewed. Here's the setup in four steps.

Step 1 — Set the threshold

Pick the amount above which purchases wait for a human. Start with your largest 'no review needed' purchase.

Set an approval threshold rule with action=flag. Transactions over the threshold return FLAGGED and route to the queue.

Assign the queue to the budget owner. Decide the response-time target and escalation path.

Review the queue weekly: approve, deny, and tune the threshold. The audit log shows the whole history.

{
  "type": "approval_threshold",
  "action": "flag",
  "params": {"over": 500, "currency": "USD"},
  "label": "Flag purchases over $500"
}

Over the threshold → FLAGGED → human decides.

What if approvals pile up?

Raise the threshold — or add more reviewers. The queue is designed to be minutes, not days.

Can different agents have different thresholds?

Yes — rules are per-agent.

One API call (or MCP tool) in front of every agent transaction — APPROVED, BLOCKED, or FLAGGED, deterministic, ~5 ms, fully logged.
