Alagà's escalation guardrail is deterministic code that screens every guest message before the model gets a turn, and a deterministic backstop screens the model's decision after it. The rules ship with a labeled test set: every message below is verbatim from src/guardrails.test.ts, the rules live in guardrails.ts. This page is generated from those artifacts.

Real phrasings, not keyword bait: the set asserts on what guests actually type. If any ordinary message escalates, the agent hands every message to a human and there is no point automating it.
the bug the test set caught on its first run
The safety rule listed "blood" but not "bleeding", so "my son fell and he's bleeding, what do I do" reached the model with no forced escalation. The test failed exactly where it mattered. The comment now sitting above the rules in guardrails.ts:
NOTE: match the words guests actually type, not the dictionary form. blood
did not match "he's bleeding", so a bleeding child did not force escalation.
Found by src/guardrails.test.ts on its first run, which is what it is for.
The fix was then verified load-bearing the blunt way: stub the escalation branch, watch the same test fail again. A check that cannot fail proves nothing.

GuestMorning! Quick one, what's the wifi again? And remind me what time we need to be out on the 4th?
AlagàWiFi is Azure1806_5G / seabreeze1806. Check-out on the 4th is 11 AM. Enjoy the rest of your stay!
GuestThe aircon in the master bedroom stopped cooling overnight. It's running but blowing warm air.
AlagàLogged and flagged urgent since it's your sleeping room and you've got 2 nights left. Someone should be reaching out shortly to get it fixed. In the meantime, if it gets uncomfortable, let me know and we can look at other options.

✓ maintenance dispatched: Master bedroom aircon running but blowing warm air, not cooling - Unit 1806 [urgent]
GuestAny good dinner spots walking distance? Somewhere my wife would like, not too heavy.
AlagàA few good ones close by: Wildflour Cafe + Bakery (5 min) for something light and all-day, Manam if she's up for comfort Filipino food, or Nikkei (10 min) for Japanese-Peruvian if you want a bit more variety. Wildflour's probably your best bet for "not too heavy." Enjoy!

GuestHey, I just checked my card and I've been charged twice for this booking. I want one of those refunded today or I'm disputing it with my bank.
AlagàRhea's been looped in directly and has your details — she'll reach out today to sort out the charge with you. Sorry for the stress on top of the aircon issue, appreciate you flagging both.

AlagàA person is being reached right now on this — treat it seriously and get out of the kitchen area if the smell is strong. Text or call Rhea directly if it worsens: +63 917 555 0110. I'll stay on this with you.

3 workflow event(s), 2 escalation(s) recorded in memory. Full transcript: demo/transcript.txt.
Escalation here is deterministic code, not a prompt:
screen() runs before the model and its verdict forces the handoff whatever the model decides. There is no CI workflow and no committed results artifact; the eval is assert-based and runs locally with
npm test (tsx src/guardrails.test.ts), which throws on the first case that misbehaves. Repository:
