Watch your own data quality

The job: know when Signal has stopped seeing your site, before you build a decision on a number that has quietly become wrong.

Who this is for: everyone. This is the workflow that protects every other workflow on this site.

The failure that matters

The dangerous failure is not an outage. An outage is loud. The dangerous failure is silence that looks like data: the pixel stops firing, or the order sync breaks, and every endpoint keeps returning 200 with numbers that are smaller than reality. Dashboards look fine. Conclusions quietly rot.

The cheapest possible check

a = requests.get(f"{BASE}/attribution", params={"days": 7}, headers=H).json()

if not a["has_data"]:
    alert("Signal attribution has no data for the last 7 days")

if a["totals"]["visitors"] < expected_floor:
    alert(f"visitors={a['totals']['visitors']}, expected at least {expected_floor}")

if a["totals"]["identify_rate"] < 0.2:
    alert(f"identify_rate has fallen to {a['totals']['identify_rate']:.0%}")

expected_floor should come from your own history, not a guess — the median of the last eight weeks is a reasonable start. A fixed threshold is wrong within a quarter.

Asking the system about itself

The assistant can answer the health questions directly, which is often faster than assembling them:

curl -s https://app.signal.geysera.com/agent-api/signal/copilot/ask \
  -H "Authorization: Bearer $SIGNAL_COPILOT_KEY" \
  -H "Content-Type: application/json" \
  -d '{"question": "Is my workspace set up properly, and have we stopped identifying visitors?"}'

workspace_setup returns store connection, onboarding progress, pixel status, identification health and plan usage in one call, and it distinguishes "nothing happened" from "we are not collecting" — which is exactly the distinction this workflow exists to make.

What to check, and how often

The last one is the one people miss. Ask "what was revenue in the last 7 days?": a workspace whose store connection has silently expired answers zero, confidently, and everything downstream inherits it.

Make the alert clearable

Before adding any check here, decide what makes it stop. An alert that fires forever is one people mute, and a muted alert is worse than none — it is a check you believe you have.

What will go wrong

A quiet weekend fires everything. Compare like with like: this Monday against previous Mondays, not against Friday.

Your own traffic. Staff and monitoring hit the site too. A floor set from history already includes them; a floor set by intuition usually does not.

Crawlers. Unflagged bot traffic has inflated visitor counts before — by a lot. If a number moves and nothing else did, check that the visitors are people before you act on it.
